== Low Res film festival on the Roof==

Visit project page [[Low Res Screen Project @ Load of Fun]]

This idea is inspired by the Graffiti Research Lab's project [http://graffitiresearchlab.com/?page_id=72#video Drive-In GIF Theater]. Basically you have people submit animated gifs and then create a giant led display to show them on. I think this might work really well for the [[Grants#Kresge Arts in Baltimore|Kresge Grant]]. Create a giant display for the roof and then ask for open submissions.

To make the project more accessible to everyone we could create a portable system for creating the animations that could be lent out to schools or others. I am thinking a digital camera on a stand with some lights, perhaps a computer, but it wouldn't be necessary. The system would convert the images to animated gifs that could be displayed on the screen.

You could also make the system web accessible. This would open up the possibility for playing simple games on the display a la [http://video.google.com/videoplay?docid=-8851774172783947549 Blinkenlights]

== Arduino Keg Meter/Barbot ==
Basically a way to measure how much beer has left a keg and the ability to log who drank how much beer. Similar project: http://kegbot.org/wiki/Main_Page
We could place the keg on a scale and measure how much less a keg weighs after a user has finished pouring, place the glass on a scale zero out the reading and then measure how much the glass weighs afterwards, or find a food safe flow meter to measure how much beer passed through the hose. I would like to use RFID to recognize each user and log the results to a webpage or a projector display of the current standings. This would be a great way to run a fund raiser and once the initial hardware was built super cheap to order extra RFID tags. I have all the supplies needed to build a kegerator except for a fridge to cool it. [[User:Mehuman|Mehuman]] 19:03, 8 July 2009 (UTC)

== Giant LED VU Meter ==
This i see as something we can assemble and sell to local clubs and maybe use for our own parties. I'm thinking large scale and go from green to yellow to red so there would be no need for RGB LEDs just wire a line of 4-5 leds and have that row display when the music reaches a certain volume.

Here is a link using a piezo to measure the volume of the music: http://www.nerdkits.com/videos/sound_meter/

The LEDs would be fairly cheap. Using this image as a template: http://www.enote.si/studio/images/vumeter.gif. If we say on average $.6 per LED, which looks a bit high but bear with me. 8 rows of 5 green + 3 rows of 5 yellow + 3 rows of 5 red = 70 LEDs * $.6 = $42 per VU Meter + cost of microcontroller ~$30. So a set of working VU Meters to put in a club would cost us ~$114 and if sold for $200-$300 we could make a nice profit while still learning and teaching.

== UAV Project(s) ==

== Guerrilla Marketing ==

What if we had a workshop where we made some sort of gorilla marketing device. One way to go would be some sort electronic apparel, like an ambient orb hat or some kind of musical shirt, etc. Or it could follow examples of other gorilla marketers like the [http://www.bikesagainstbush.com/blog/about.php|chalk printing bicycle] or the [http://laughingsquid.com/aqua-teen-hunger-force-promo-causes-panic-in-boston Boston Aqua Teen Hunger Force flashing LED signs]. Something simple, fun and easy to individualize. Why not tell people about the newly energized Baltimore maker/tinker/hacker/builder/breaker community?

* go for it, any volunteers to organize? [[User:Abachman|Abachman]] 23:25, 8 July 2009 (UTC)

== Ambient Orb [DONE July 2009] ==

== Weather Instruments and Networks ==

Build weather instruments, assemble into a weather station using wifi, etc. Install around Inner Harbor, and "Northwest Harbor" (Canton). Especially wind and waves for sailors.

Instruments, compare with Ft. McHenry data http://opendap.co-ops.nos.noaa.gov/stations/stationData.jsp?id=8574680 and http://tidesandcurrents.noaa.gov/geo.shtml?location=21201

Feed data to:
* weather underground http://www.wunderground.com/weatherstation/index.asp
* Citizen Weather Observer Program http://www.wxqa.com/ and http://www.findu.com/
* NOAA http://www.nws.noaa.gov/om/coop/ & other programs
* Local marinas & sailing centers:
** downtownsailing.org

Installation locations:
* downtownsailing.org at Baltimore Museum of Industry, Riverside/Locust Point.
* Marinas

===== Display stations =====
Build a small display station with LCD display from salvaged laptop showing wind, waves, sever-weather/radar, etc. for the Inner Harbor. Install at marinas, etc.

== AM Radio Transmitter ==
You don't need any sort of licensing to broadcast on AM frequencies if your transmitter is 100 milliwatts or less. A transmitter with a basic wire antenna can get 50 to 200 feet of range, however a more substantial outdoor antenna can transmit as far as two miles. I would be interested in setting up an internet radio station and then using multiple transmitters to broadcast that station over AM around Baltimore. The transmitter stations would require enough computing resources to connect to the internet in some way, decode an internet radio stream, and output an audio signal to the AM transmitter. The transmitters themselves can be purchased for about $75-100 dollars, but it's possible we could construct a transmitter from plans for much cheaper. Five to ten well placed transmitters could cover a significant amount Baltimore city.

===== Steps =====

* Setup a stream
* Build an Arduino/xbee that dials into the stream and outputs audio (I'm don't think an Arduino has the processing power to connect to the internet, decode an audio stream, and provide an analog output. An old laptop or eeepc, which already had network and audio interfaces might be cheap enough to work. [[User:Jonlesser|Jonlesser]] 03:04, 2 July 2009 (UTC))
* Connect audio with AM transmitter
* Build a nice case with antennae(s)
* Replicate and distribute
* Broadcast to the masses

===== Hacker Radio Broadcast topics =====

* Freeculture
* DIY discussions
* Copyright law
* Opensource
* Coverage of local events
* Creative Commons music show?

== Intervention at Baltimore Development Collective's geodesic dome ==
[http://www.flickr.com/photos/artbma/3620589054/ This dome] won the Sondheim Artscape Prize. It's located in front of the Baltimore Museum of Art. It is just begging for a techno-art intervention from the Baltimore Node.

== RFID-tag City Landmarks ==

Wireless mesh?
Public Computer Centers ([http://broadbandusa.sc.egov.usda.gov/files/BB%20NOFA%20FINAL%20with%20disclaimer_1.pdf PDF]) - Federal stimulus funds available. Application window is July 14-August 14. <br>
(Is this a better link? [http://broadbandusa.sc.egov.usda.gov/forms/PCC/Public%20Computer%20Centers%20Application.pdf PDF])
I am definitely interested in developing this --[[User:Antilog|Erich Steiger]] 03:19, 16 July 2009 (UTC)

* ''The "Public Computer Centers" application process includes a 15 page form and something like 20 pages of written documentation (http://www.newamerica.net/files/Public%20Computer%20Centers%20Program%20Application%20Guide.pdf). The estimate given in the program application guide for the application process alone is 140 hours of work times six people (i.e., 720 person-hours total). That's probably out of scope for Node (since we have no employees or full-time volunteers). [[User:Abachman|Abachman]] 16:27, 31 July 2009 (UTC)''

== Circuit Bending 101 ==
All-ages introduction to hacking electronic toys and digital electronics.

==== Parts ====
* Toys from salvation army and other thrift stores
* Soldering iron and solid core wire
* Continuity/Voltage/Current Tester
* Heat Sink Tubing

== Roof Top Garden ==
I know we have roof top access at the LoF. I have not seem the roof yet and we would have to ask Sherwin but i think it would be cool to build a roof top garden it would also help satisfy the sustainability aspect some people talked about. We could also make it nerdy and wire up some sensors to monitor the soil moisture and remind us to water.
* Yeah, I really want to do some kind of garden-hacking. Here's a Garduino project from Instructables - it's for indoor gardening: http://www.instructables.com/id/Garduino_Gardening_Arduino/ [[User:Sylviachi|Sylviachi]] 02:48, 18 July 2009 (UTC)

== Backyard Fish Farming ==
<blockquote>''Now, a growing group of urban agriculture enthusiasts are translating the practice of land-based fish farming to a very local level. Their system of choice is called aquaponics -- a symbiotic setup in which plants and fish are raised simultaneously in recirculating water. The two "crops" are complementary: fish waste fertilizes the plants, which naturally filter the water so that it stays clean even when many fish are raised in close quarters (one might even call it a form of heavily engineered polyculture).''</blockquote>

Sounds like more fun than urban chicken farming. What's the minimal sustainable size needed for a project like this?

== Construction Assistance ==

If we have light shop tools and experienced folks on hand we might be able to offer open shop hours for drop-in fee based tool use. Similar to [http://www.bethsdiyworkshop.com/ Beth's DIY Workshop], we're not going to do it for you (this isn't a cheap form of appliance repair), but we can help you do it. [[User:Abachman|Abachman]] 19:32, 17 July 2009 (UTC)

== Fab Lab ==

Build our own MIT-style Fab Lab. From the FAQ:

''Fab labs have spread from inner-city Boston to rural India, from South Africa to the North of Norway. Activities in fab labs range from technological empowerment to peer-to-peer project-based technical training to local problem-solving to small-scale high-tech business incubation to grass-roots research. Projects being developed and produced in fab labs include solar and wind-powered turbines, thin-client computers and wireless data networks, analytical instrumentation for agriculture and healthcare, custom housing, and rapid-prototyping of rapid-prototyping machines.''

''Fab labs share core capabilities, so that people and projects can be shared across them. This currently includes:''

* ''A computer-controlled lasercutter, for press-fit assembly of 3D structures from 2D parts''
* ''A larger (4'x8') numerically-controlled milling machine, for making furniture- (and house-) sized parts''
* ''A signcutter, to produce printing masks, flexible circuits, and antennas''
* ''A precision (micron resolution) milling machine to make three-dimensional molds and surface-mount circuit boards''
* ''Programming tools for low-cost high-speed embedded processors''

This would be a large scale effort, featuring lots of fundraising (50 to 60 thousand dollars) and more space hunting, but would satisfy a lot of folks' initial visions for B'node.

== RFID Door ==
A way of entering and leaving the space with out having to buy a $15 key. Invisible to the outside. To start all codes would be hardcoded into the Arduino but as we get more sophisticated codes could be accessed from a database that the kegerator would also have access too. I have code from a guy named Arclight that has the majority everything written out. [[User:Mehuman|Mehuman]]

=== Parts ===
* Arduino
* RFID Reader - I have a Parallax one to donate [[User:Mehuman|Mehuman]]
* RFID Tags or Fobs
* Electric Strike to open door.[http://cgi.ebay.com/ELECTRIC-STRIKE-LOCK-FAIL-SECURE_W0QQitemZ400047589508QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item5d24b1c884 $25 on eBay]

== Automate the Entire Space ==
I bought a ton of x10 stuff of a guy for really cheap and think it would be a great idea to set it all up a the space. I have 5 cameras, 1 with pan and tilt. 2 rca to usb devices, 1 works with linux the other i have yet to test. I have 2 computer control devices, Firecracker CM17A and Activehome CM15A both work with linux. a motion sensor that will turn on and off the lights with movement. This all can be controlled by Mister Home. [[User:Mehuman|Mehuman]]

== Giant Vibrobot ==

world record sized vibrobot with motorcycle engine and electrical conduit for bristles.

== Laser Projector ==

Laser with culminating lens and small lcd screen stripped of backing.

== Steam Dot Matrix Sky Printer ==

Using steam or fog machine, hoses and servo articulated ends 'print' smoke patterns.

== Helium foam printer ==

controlled helium gas through a bubble solution to make floating 3D sculptures.

== PixelVision clone ==

One of these: http://en.wikipedia.org/wiki/PXL-2000 with an arduino and a walkman.

== Wayward Bike ==

A bike that twitters it's location and takes pictures automatically.

On a sweet chopper bike donated from Velocipede install an inexpensive boost mobile phone with GPS and bluetooth interface a low profile unix device to take pictures from web cams facing the biker and forward to be updated in a twitter feed and mologogo service. Device would be integrated as part of a stereo/lights system (spoke POV!) powered by C cell batteries and solar array and with a charging system.

The bike would be left out with a full explanation that by using the bike you agree to have your image and location posted online and will not hold velocipede/node responsible for getting run over in traffic and that the bike is free for anyone to use when you are not in transit.

This is an opportunity to explore inexpensive unix embedded systems and to collaborate with velocipede to combine our collective tools (I really want to use that welder!) and expertise and to generate interest in our groups with online promotion.

== Wayward Bike Mark II Summer 2011 ==
refined open source system that to use requires recording a short video interview before using the bike. Biometric identification system that gathers statistics about where it goes and how fast. bike computer informational system that uses google maps, geocaching and user created content. locationally aware systems provide sound track and lighting system changes by user generated content.

== Wayward Bike Mark III sell out edition ==
Utilizing open source tools and corporate sponsors Wayward bike systems mass produced will be available on freely available bikes (similar to the unlocked black bikes in Amsterdam) and will make me rich by providing locationally aware advertising content to the bikes. Having retired I will spend all my time at node puttering and providing generous donations

So a set of working VU Meters to put in a club would cost us ~$114 and if sold for $200-$300 we could make a nice profit while still learning and teaching.

== Guerrilla Marketing ==

What if we had a workshop where we made some sort of gorilla marketing device. One way to go would be some sort electronic apparel, like an ambient orb hat or some kind of musical shirt, etc. Or it could follow examples of other gorilla marketers like the [http://www.bikesagainstbush.com/blog/about.php|chalk printing bicycle] or the [http://laughingsquid.com/aqua-teen-hunger-force-promo-causes-panic-in-boston Boston Aqua Teen Hunger Force flashing LED signs]. Something simple, fun and easy to individualize. Why not tell people about the newly energized Baltimore maker/tinker/hacker/builder/breaker community?

* go for it, any volunteers to organize? [[User:Abachman|Abachman]] 23:25, 8 July 2009 (UTC)

== Weather Instruments and Networks ==

Build weather instruments, assemble into a weather station using wifi, etc. Install around Inner Harbor, and "Northwest Harbor" (Canton). Especially wind and waves for sailors.

Instruments, compare with Ft. McHenry data http://opendap.co-ops.nos.noaa.gov/stations/stationData.jsp?id=8574680 and http://tidesandcurrents.noaa.gov/geo.shtml?location=21201

Feed data to:
* weather underground http://www.wunderground.com/weatherstation/index.asp
* Citizen Weather Observer Program http://www.wxqa.com/ and http://www.findu.com/
* NOAA http://www.nws.noaa.gov/om/coop/ & other programs
* Local marinas & sailing centers:
** downtownsailing.org

Installation locations:
* downtownsailing.org at Baltimore Museum of Industry, Riverside/Locust Point.
* Marinas

===== Display stations =====
Build a small display station with LCD display from salvaged laptop showing wind, waves, sever-weather/radar, etc. for the Inner Harbor. Install at marinas, etc.

== AM Radio Transmitter ==
You don't need any sort of licensing to broadcast on AM frequencies if your transmitter is 100 milliwatts or less. A transmitter with a basic wire antenna can get 50 to 200 feet of range, however a more substantial outdoor antenna can transmit as far as two miles. I would be interested in setting up an internet radio station and then using multiple transmitters to broadcast that station over AM around Baltimore. The transmitter stations would require enough computing resources to connect to the internet in some way, decode an internet radio stream, and output an audio signal to the AM transmitter. The transmitters themselves can be purchased for about $75-100 dollars, but it's possible we could construct a transmitter from plans for much cheaper. Five to ten well placed transmitters could cover a significant amount Baltimore city.

===== Steps =====

* Setup a stream
* Build an Arduino/xbee that dials into the stream and outputs audio (I'm don't think an Arduino has the processing power to connect to the internet, decode an audio stream, and provide an analog output. An old laptop or eeepc, which already had network and audio interfaces might be cheap enough to work. [[User:Jonlesser|Jonlesser]] 03:04, 2 July 2009 (UTC))
* Connect audio with AM transmitter
* Build a nice case with antennae(s)
* Replicate and distribute
* Broadcast to the masses

===== Hacker Radio Broadcast topics =====

* Freeculture
* DIY discussions
* Copyright law
* Opensource
* Coverage of local events
* Creative Commons music show?

(Is this a better link? [http://broadbandusa.sc.egov.usda.gov/forms/PCC/Public%20Computer%20Centers%20Application.pdf PDF])
I am definitely interested in developing this --[[User:Antilog|Erich Steiger]] 03:19, 16 July 2009 (UTC)

* ''The "Public Computer Centers" application process includes a 15 page form and something like 20 pages of written documentation (http://www.newamerica.net/files/Public%20Computer%20Centers%20Program%20Application%20Guide.pdf). The estimate given in the program application guide for the application process alone is 140 hours of work times six people (i.e., 720 person-hours total). That's probably out of scope for Node (since we have no employees or full-time volunteers). [[User:Abachman|Abachman]] 16:27, 31 July 2009 (UTC)''

== Circuit Bending 101 ==

== Roof Top Garden ==
I know we have roof top access at the LoF. I have not seem the roof yet and we would have to ask Sherwin but i think it would be cool to build a roof top garden it would also help satisfy the sustainability aspect some people talked about. We could also make it nerdy and wire up some sensors to monitor the soil moisture and remind us to water.
* Yeah, I really want to do some kind of garden-hacking. Here's a Garduino project from Instructables - it's for indoor gardening: http://www.instructables.com/id/Garduino_Gardening_Arduino/ [[User:Sylviachi|Sylviachi]] 02:48, 18 July 2009 (UTC)

== Backyard Fish Farming ==
<blockquote>''Now, a growing group of urban agriculture enthusiasts are translating the practice of land-based fish farming to a very local level. Their system of choice is called aquaponics -- a symbiotic setup in which plants and fish are raised simultaneously in recirculating water. The two "crops" are complementary: fish waste fertilizes the plants, which naturally filter the water so that it stays clean even when many fish are raised in close quarters (one might even call it a form of heavily engineered polyculture).''</blockquote>

Sounds like more fun than urban chicken farming. What's the minimal sustainable size needed for a project like this?

== Construction Assistance ==

If we have light shop tools and experienced folks on hand we might be able to offer open shop hours for drop-in fee based tool use. Similar to [http://www.bethsdiyworkshop.com/ Beth's DIY Workshop], we're not going to do it for you (this isn't a cheap form of appliance repair), but we can help you do it.

== Fab Lab ==

Build our own MIT-style Fab Lab. From the FAQ:

''Fab labs have spread from inner-city Boston to rural India, from South Africa to the North of Norway. Activities in fab labs range from technological empowerment to peer-to-peer project-based technical training to local problem-solving to small-scale high-tech business incubation to grass-roots research. Projects being developed and produced in fab labs include solar and wind-powered turbines, thin-client computers and wireless data networks, analytical instrumentation for agriculture and healthcare, custom housing, and rapid-prototyping of rapid-prototyping machines.''

''Fab labs share core capabilities, so that people and projects can be shared across them. This currently includes:''

* ''A computer-controlled lasercutter, for press-fit assembly of 3D structures from 2D parts''
* ''A larger (4'x8') numerically-controlled milling machine, for making furniture- (and house-) sized parts''
* ''A signcutter, to produce printing masks, flexible circuits, and antennas''
* ''A precision (micron resolution) milling machine to make three-dimensional molds and surface-mount circuit boards''
* ''Programming tools for low-cost high-speed embedded processors''

This would be a large scale effort, featuring lots of fundraising (50 to 60 thousand dollars) and more space hunting, but would satisfy a lot of folks' initial visions for B'node.

On a sweet chopper bike donated from Velocipede install an inexpensive boost mobile phone with GPS and bluetooth interface a low profile unix device to take pictures from web cams facing the biker and forward to be updated in a twitter feed and mologogo service. Device would be integrated as part of a stereo/lights system powered by C cell batteries and solar array and with a charging system.

The bike would be left out with a full explanation that by using the bike you agree to have your image and location posted online and will not hold velocipede/node responsible for getting run over in traffic and that the bike is free for anyone to use when you are not in transit.

This is an opportunity to explore inexpensive unix embedded systems and to collaborate with velocipede to combine our collective tools (I really want to use that welder!) and expertise and to generate interest in our groups with online promotion.

== Wayward Bike Mark II Summer 2011 ==
refined open source system that to use requires recording a short video interview before using the bike. Biometric identification system that gathers statistics about where it goes and how fast. bike computer informational system that uses google maps, geocaching and user created content. locationally aware systems provide sound track and lighting system changes by user generated content.

== Wayward Bike Mark III sell out edition ==
Utilizing open source tools and corporate sponsors Wayward bike systems mass produced will be available on freely available bikes (similar to the unlocked black bikes in Amsterdam) and will make me rich by providing locationally aware advertising content to the bikes. Having retired I will spend all my time at node puttering and providing generous donations

===Questions for Workshop88 competition===

'''Does the cost refer just to the payload or payload + balloon and recovery equipment?'''

'''When does the 45 minute clock start?'''

==== From the FAQ: ====

'''Can I used donated items to offset the cost of my balloon?'''
*No, even if an item is donated you need to assign a universally accepted value to it. IE: MSRP, average eBay price, etc...

'''Why do I have to count the value of donated item'''
*A meaningful price cap levels the playing field for all groups and pushes them to innovate.

'''Is there a prize? Can we make a donation of an item or cash as part of the pot? What do we get if we win?'''
*Bragging rights, a cool trophy made by the members of Workshop 88, and the honor of building next year's trophy.

===Goals of Node Space Shot===

Why we should go to near space:

It's a spectacular and achievable goal with lots of design challenges requiring robust methods and coordinated work.

The challenges include extreme cold, condensation, extreme force, unreliable data and luck.

With other hacker spaces working on the Workshop88 competition and general interest this is an opportunity to both collaborate with other hacker spaces and to establish Node's own style. Opportunities exist for developing methods for payload data recording, tracking and recovery methods.

Near space cooled shot of vodka.

Objective:
Send stuff to near space by baloon, recover stuff relatively intact. Use easily available materials when possible. Create software and methods easily available for other groups to repeat.

Launch:
We need to learn the methods for inflating and handling the baloon to allow for optimal and controlled release.

Location location location. Brief experimentation with ucam.org's tools shows a launch in Baltimore County will land 100 miles in to the ocean parallel to NJ. A launch in Pittsburgh would land in Philly or DC depending on latitude. MD and the east coast in general is lousy for a launch effort because of the jet stream and not so great for recovery because the terrain is primarily wooded/urban.

Launch Proposal: using google maps and google charts, python, GRIB data, google apps/amazon develop applications for landing predictions and embedded unix based flight control software.

We should prepare to use a launch and recovery site not in state. This is kind of a bummer because space is just above us, but also a boon because A) collaboration with other hacker spaces for using members and resources. B) ROAD TRIP!

Payload:
The goals of the payloads goals are to gather information and return them safely through low temperatures, moisture and recoverable from falling to earth.

There is a richness of materials to work with available in consumer items for this requirement. Data must be stored in a way that will be recoverable after power interruptions and extreme physical duress.

Payload proposal:
Using ziplock bags, styrofoam, thermal blankets and a spraying of electronics with non conductive oils, use arduino with SD card to record data.

Telematics (Telemetry):
XYZ

Accurate measurements and reporting of position and height through out flight. Consumer electronics are easily available but limited in scope. GPS position and altitude are measurable by a variety of methods.

Avionics:
Get up and then get down!

Getting up is relatively straight forward, but leaves a lot to experimentation. Balloons need to be properly inflated not to swell too much and pop at altitude. Proper handling of the balloon is essential to optimal performance.

Getting down will happen, the key is to choosing how predictably and violently the trip down goes.

Recovery:
Let's try and not drop a payload from near space at terminal velocity on someone's head. Oh, and littering is bad mkay?

Deploying a chute too early will cause the craft to drift with the wind recovery area can be reported by gps enabled cellphone and refined by RF beacon signal and audible beacon.

Idea: lifting body and active avionics can guide the payload back to a easier to identify area.

Phase I
construct avionics and telemetry systems.

Phase II
drop stuff off building, stick in freezer.

Phase III
drop stuff off of lower altitude balloon.

Phase IIII
test flight to test and calibrate systems.

Phase IV
Flights for extreme capacities for contest and other goals.

== Classes ==

=== Programming for Kids ===

I'd like to teach an intro to programming class aimed at all / any ages. Most likely based on games / graphics. [http://hacketyhack.net/ Hackety Hack], [http://love2d.org/ Love 2D], and [http://processing.org Processing] are potential frameworks. [[User:Abachman|Abachman]] 20:13, 7 July 2009 (UTC)
* I'm interested. Especially in processing. --[[User:Antilog|Erich Steiger]] 03:37, 16 July 2009 (UTC)
* I'm very much into this too and feel that I could teach a few classes of "intro to processing" --[[User:Mattyfo|Mattyfo]] 16:41, 16 July 2009 (UTC)

=== Open Workshop for Homeschoolers ===

There are a lot of kids who aren't trapped in the educational prison system during the daylight hours who might be interested in a regularly occurring class or open space. I'll be contacting the various co-op groups I have connections with, but I know there's a woodshop that gives kids (10 + years old?) a space to come and work on projects. The goal would be to provide the exact same thing we're looking for except on an hourly fee schedule.

What I'm suggesting is very specifically an unstructured time. Leave the textbooks and lessons at home. Kids have as much (probably more) curiosity and interest in this stuff as we do. Members would be present to guide, answer questions, and help with safety related issues. [[User:Abachman|Abachman]] 20:31, 7 July 2009 (UTC)

Has anyone heard of Beth's DIY Workshop. It is a wood shop where she teaches woodworking and basic home repairs type classes. It is also available for use if you need wood tools but don't have a shop. It is on Harford Road. [[User:Kellyegan|Kellyegan]] 16:00, 10 July 2009 (UTC)

=== "Official" Student Groups ===

Question to folks connected with universities and high schools: what is the potential for marketing the space to art and tech profs and teachers who might be interested in hosting their class in the space, or perhaps stopping by for a field trip? Second, what is the possibility that those official groups could be asked to donate in exchange for quiet use of the space? [[User:Abachman|Abachman]] 20:31, 7 July 2009 (UTC)

* The space would have to provide added benefits over traditional or existing classrooms. It might be a good fit for a high school class or club which doesn't have the resources that a university has. Field trips seem pretty easy to arrange but we would need to provide some sort of educational content. Also for college students particularly art students who in their first couple of years don't have access to studio space. This might be a great resource. Also school without dedicated spaces for shop/construction work might be interested. [[User:Kellyegan|Kellyegan]] 23:54, 29 July 2009 (UTC)

=== SketchUp Workshop ===
[http://sketchup.google.com/ SketchUp] is a free 3d modeling program acquired by Google a few years back. I've been using it a lot recently to design robots and art projects. I propose a workshop to introduce folks to the basics of SketchUp modeling as a tool for ideation. Topics: Navigating 3d space, building geometry and extruding forms, importing 3d models from Google's 3d warehouse, sharing your models with the world, integration with google earth, exporting models to meatspace (laser cutting). It could be a 2 hour deal, a full day, or a weekend depending on who's interested and how deep people want to go. If there is sustained interest, it could grow either into a SketchUp users group hosted at the Node or branch out to other digital ideation tools, e.g. [http://usa.autodesk.com/adsk/servlet/index?id=6848332&siteID=123112 SketchBook Pro], [http://usa.autodesk.com/adsk/servlet/index?id=7635018&siteID=123112 Maya], Photoshop, etc. --[[User:Jonlesser|Jonlesser]] 05:22, 11 July 2009 (UTC)
* I would be interested in this as a short course. Would love to do room layouts like you did for the Lof space. [[User:Mehuman|Mehuman]] 13:29, 11 July 2009 (UTC)
* Am interested --[[User:Antilog|Erich Steiger]] 03:39, 16 July 2009 (UTC)

=== Basic Electronics ===
Basics of electronics starting with fundamentals, passive components, transistors, etc. with a focus on practical application. Soldering tips, etc. Willing to help, probably someone else with more experience to take lead? [[User:Antilog|Erich Steiger]] 03:44, 16 July 2009 (UTC)

=== Biodiesel Workshop ===
I have a diesel VW and used to occasionally fill up with B100 at a biodiesel station when I lived in Berkeley. Biodiesel is not too hard to make, especially in small batches. We could talk about biodiesel and straight veg oil and maybe have everyone make a small batch (1QT). There is a [http://www.baltimorebiodiesel.org/index.php biodiesel coop] in Baltimore that we could reach out to and see if one of their people would be interested in lending some expertise. --[[User:Jonlesser|Jonlesser]] 00:18, 17 July 2009 (UTC)

== Events ==

=== Craft Night ===

I'm not part of this scene (yet?) but there is definite potential for outreach. [http://www.nycresistor.com/2009/05/01/craft-night-review/ NYC Resistor has had success with craft nights] as an ongoing event.

From NYC Resistor (emphasis mine):
<blockquote>What: Craft night---an open project night where people bring projects they have been working on or meaning to work on for awhile. In the past people have worked on knitting, mending, clothing reconstruction, web design, robots, etc. The definition of 'craft' is very loose. Where: NYC Resistor Lab 397 Bridge St. 5th Floor, Brooklyn, NY Who would like this: People who like to make stuff. '''Why: So you don't have to make stuff by yourself.'''</blockquote>

=== Pedal Hacking Workshop ===

[[Pedal Hacking Workshop|Guitar pedals, building / modding / hacking.]] Bring your own to mod, or build your own. Let's hash out the details on the mailing list. -[[User:Antilog|Erich Steiger]] 02:47, 5 August 2009 (UTC)

=== Powertool Drag Racing ===

TSIA...

== Meetups ==

===DIY Bio===

Start a regular, monthly or semi-monthly meetup as part of the existing [http://diybio.org/about/ DIYBio] movement.

<blockquote>DIYbio is an organization that aims to help make biology a worthwhile pursuit for citizen scientists, amateur biologists, and DIY biological engineers who value openness and safety. This will require mechanisms for amateurs to increase their knowledge and skills, access to a community of experts, the development of a code of ethics, responsible oversight, and leadership on issues that are unique to doing biology outside of traditional professional settings.</blockquote>

''I have no experience in this area, beyond a (weak) connection to a Hopkins graduate biophysics research lab. I would love to start sequencing and modifying some DNA, however. [[User:Abachman|Abachman]] 17:35, 29 July 2009 (UTC)''

===Code in the Morning===

Evenings are hard for me to make a regular meeting, mornings are easier. I'll probably be in the space one or two mornings a week, doing my indie code thing. Why not grab a cuppa joe and join me?

How does 7:30AM - 9:30AM on Mondays sound?

== Wifi Antenna From old Satellite Dish ==
I just canceled my directv and they don't want the dish back. I've seen them used before to improve wifi signals. If there was any place near by with open wifi that we wanted to pick up we could build this to allow us access.

[[User:Mehuman|Mehuman]] 20:27, 20 July 2009 (UTC)

== Low Res film festival on the Roof==

Visit project page [[Low Res Screen Project @ Load of Fun]]

This idea is inspired by the Graffiti Research Lab's project [http://graffitiresearchlab.com/?page_id=72#video Drive-In GIF Theater]. Basically you have people submit animated gifs and then create a giant led display to show them on. I think this might work really well for the [[Grants#Kresge Arts in Baltimore|Kresge Grant]]. Create a giant display for the roof and then ask for open submissions.

To make the project more accessible to everyone we could create a portable system for creating the animations that could be lent out to schools or others. I am thinking a digital camera on a stand with some lights, perhaps a computer, but it wouldn't be necessary. The system would convert the images to animated gifs that could be displayed on the screen.

You could also make the system web accessible. This would open up the possibility for playing simple games on the display a la [http://video.google.com/videoplay?docid=-8851774172783947549 Blinkenlights]

== Arduino Keg Meter/Barbot ==
Basically a way to measure how much beer has left a keg and the ability to log who drank how much beer. Similar project: http://kegbot.org/wiki/Main_Page
We could place the keg on a scale and measure how much less a keg weighs after a user has finished pouring, place the glass on a scale zero out the reading and then measure how much the glass weighs afterwards, or find a food safe flow meter to measure how much beer passed through the hose. I would like to use RFID to recognize each user and log the results to a webpage or a projector display of the current standings. This would be a great way to run a fund raiser and once the initial hardware was built super cheap to order extra RFID tags. I have all the supplies needed to build a kegerator except for a fridge to cool it. [[User:Mehuman|Mehuman]] 19:03, 8 July 2009 (UTC)

* A way to sense if the beer is flowing, a flow sensor?

== Giant LED VU Meter ==
This i see as something we can assemble and sell to local clubs and maybe use for our own parties. I'm thinking large scale and go from green to yellow to red so there would be no need for RGB LEDs just wire a line of 4-5 leds and have that row display when the music reaches a certain volume.

Here is a link using a piezo to measure the volume of the music: http://www.nerdkits.com/videos/sound_meter/

The LEDs would be fairly cheap. Using this image as a template: http://www.enote.si/studio/images/vumeter.gif. If we say on average $.6 per LED, which looks a bit high but bear with me. 8 rows of 5 green + 3 rows of 5 yellow + 3 rows of 5 red = 70 LEDs * $.6 = $42 per VU Meter + cost of microcontroller ~$30. So a set of working VU Meters to put in a club would cost us ~$114 and if sold for $200-$300 we could make a nice profit while still learning and teaching.

== UAV Project(s) ==

== Guerrilla Marketing ==

What if we had a workshop where we made some sort of gorilla marketing device. One way to go would be some sort electronic apparel, like an ambient orb hat or some kind of musical shirt, etc. Or it could follow examples of other gorilla marketers like the [http://www.bikesagainstbush.com/blog/about.php|chalk printing bicycle] or the [http://laughingsquid.com/aqua-teen-hunger-force-promo-causes-panic-in-boston Boston Aqua Teen Hunger Force flashing LED signs]. Something simple, fun and easy to individualize. Why not tell people about the newly energized Baltimore maker/tinker/hacker/builder/breaker community?

== Weather Instruments and Networks ==

Build weather instruments, assemble into a weather station using wifi, etc. Install around Inner Harbor, and "Northwest Harbor" (Canton). Especially wind and waves for sailors.

Instruments, compare with Ft. McHenry data http://opendap.co-ops.nos.noaa.gov/stations/stationData.jsp?id=8574680 and http://tidesandcurrents.noaa.gov/geo.shtml?location=21201

Feed data to:
* weather underground http://www.wunderground.com/weatherstation/index.asp
* Citizen Weather Observer Program http://www.wxqa.com/ and http://www.findu.com/
* NOAA http://www.nws.noaa.gov/om/coop/ & other programs
* Local marinas & sailing centers:
** downtownsailing.org

Installation locations:
* downtownsailing.org at Baltimore Museum of Industry, Riverside/Locust Point.
* Marinas

===== Display stations =====
Build a small display station with LCD display from salvaged laptop showing wind, waves, sever-weather/radar, etc. for the Inner Harbor. Install at marinas, etc.

== AM Radio Transmitter ==
You don't need any sort of licensing to broadcast on AM frequencies if your transmitter is 100 milliwatts or less. A transmitter with a basic wire antenna can get 50 to 200 feet of range, however a more substantial outdoor antenna can transmit as far as two miles. I would be interested in setting up an internet radio station and then using multiple transmitters to broadcast that station over AM around Baltimore. The transmitter stations would require enough computing resources to connect to the internet in some way, decode an internet radio stream, and output an audio signal to the AM transmitter. The transmitters themselves can be purchased for about $75-100 dollars, but it's possible we could construct a transmitter from plans for much cheaper. Five to ten well placed transmitters could cover a significant amount Baltimore city.

===== Steps =====

* Setup a stream
* Build an Arduino/xbee that dials into the stream and outputs audio (I'm don't think an Arduino has the processing power to connect to the internet, decode an audio stream, and provide an analog output. An old laptop or eeepc, which already had network and audio interfaces might be cheap enough to work. [[User:Jonlesser|Jonlesser]] 03:04, 2 July 2009 (UTC))
* Connect audio with AM transmitter
* Build a nice case with antennae(s)
* Replicate and distribute
* Broadcast to the masses

===== Hacker Radio Broadcast topics =====

* Freeculture
* DIY discussions
* Copyright law
* Opensource
* Coverage of local events
* Creative Commons music show?

== Intervention at Baltimore Development Collective's geodesic dome ==
[http://www.flickr.com/photos/artbma/3620589054/ This dome] won the Sondheim Artscape Prize. It's located in front of the Baltimore Museum of Art. It is just begging for a techno-art intervention from the Baltimore Node.

== Circuit Bending 101 ==
All-ages introduction to hacking electronic toys and digital electronics.

==== Parts ====
* Toys from salvation army and other thrift stores
* Soldering iron and solid core wire
* Continuity/Voltage/Current Tester
* Heat Sink Tubing

== Roof Top Garden ==
I know we have roof top access at the LoF. I have not seem the roof yet and we would have to ask Sherwin but i think it would be cool to build a roof top garden it would also help satisfy the sustainability aspect some people talked about. We could also make it nerdy and wire up some sensors to monitor the soil moisture and remind us to water.
* Yeah, I really want to do some kind of garden-hacking. Here's a Garduino project from Instructables - it's for indoor gardening: http://www.instructables.com/id/Garduino_Gardening_Arduino/ [[User:Sylviachi|Sylviachi]] 02:48, 18 July 2009 (UTC)

== Backyard Fish Farming ==
<blockquote>''Now, a growing group of urban agriculture enthusiasts are translating the practice of land-based fish farming to a very local level. Their system of choice is called aquaponics -- a symbiotic setup in which plants and fish are raised simultaneously in recirculating water. The two "crops" are complementary: fish waste fertilizes the plants, which naturally filter the water so that it stays clean even when many fish are raised in close quarters (one might even call it a form of heavily engineered polyculture).''</blockquote>

Sounds like more fun than urban chicken farming. What's the minimal sustainable size needed for a project like this?

If we have light shop tools and experienced folks on hand we might be able to offer open shop hours for drop-in fee based tool use. Similar to [http://www.bethsdiyworkshop.com/ Beth's DIY Workshop], we're not going to do it for you (this isn't a cheap form of appliance repair), but we can help you do it.

== Fab Lab ==

Build our own MIT-style Fab Lab. From the FAQ:

''Fab labs have spread from inner-city Boston to rural India, from South Africa to the North of Norway. Activities in fab labs range from technological empowerment to peer-to-peer project-based technical training to local problem-solving to small-scale high-tech business incubation to grass-roots research. Projects being developed and produced in fab labs include solar and wind-powered turbines, thin-client computers and wireless data networks, analytical instrumentation for agriculture and healthcare, custom housing, and rapid-prototyping of rapid-prototyping machines.''

''Fab labs share core capabilities, so that people and projects can be shared across them. This currently includes:''

* ''A computer-controlled lasercutter, for press-fit assembly of 3D structures from 2D parts''
* ''A larger (4'x8') numerically-controlled milling machine, for making furniture- (and house-) sized parts''
* ''A signcutter, to produce printing masks, flexible circuits, and antennas''
* ''A precision (micron resolution) milling machine to make three-dimensional molds and surface-mount circuit boards''
* ''Programming tools for low-cost high-speed embedded processors''

This would be a large scale effort, featuring lots of fundraising (50 to 60 thousand dollars) and more space hunting, but would satisfy a lot of folks' initial visions for B'node.

== Lantern Parade ==

Working with NANA projects create some designs for LED/EL wire lanterns of varying complexity and costs to use in NANA Projects Lantern Parade.

Lanterns can include electro mechanical connections to cause blinking up to arduino controlled POV displays.
