Here's a piece talking about both the importance and practice of building community at a hackerspace or makerspace. From MAKE:

Occasionally, I'll visit a frustrated makerspace. "We have a space. We have tools. Where are the members?" They describe how they've put energy into the physical aspects of the space and say nothing about the community building aspects. To this I typically reply that a makerspace without a community is a soulless place. Without a soul there's little passion and therefore little stickiness for prospective members. It's not easy to create community but it's an important theme to develop. One way to do this is to tap into existing community. Below are some techniques we've used at Nova Labs.

Most cities have interest groups of many types. As a simple test, go to Meetup.com and do a search for what exists in your community. You may find several groups with maker instincts: woodworking, robotics, PHP coding, etc. On Meetup.com alone, the variety in major metropolitan areas is staggering. Identify a few and get to know them. By doing only this, you can discover mutually beneficial opportunity to nurture community.

Our makerspace was actually founded with one such group at its core: Northern Virginia RepRap Group. NovaRRG is a hub of 3D printing enthusiasts and experts who meet regularly and build Prusa 3D printers. As time has gone by, we've reached out to the DC/MD/VA Robotics and Automation Group because our robotics enthusiasts were champing at the bit to do things. It turned out the group needed a space to meet regularly so we offered our conference room and several collaborations have resulted. We also connected with the DC Area Drone User Group because, heck, we wanted to fly drones! Leveraging Nova Labs' space, resources, and 3D printer group build expertise we collaborated on a kit build with great success. In each case, we've been careful to work together for mutual benefit so both communities continue to want to work together.

Problem interfacing tdb380/mdfly to arduino

Have one of these remarkable little modules which plays mp3 files OK. Two problems:
1. Despite using drivesort serial commands dont always produce desired file
2. Volume keeps resetting to zero and has to be increased via hardware.

Which water sensor to buy ?

Posted: 22 Jan 2013 01:28 AM PST

Good morning,
I'm from France and I have a request for my project.
I need to manage the level of water bewteen two tanks (the water will fall down from one to the other) .
So considering that the quantity of water will not change, I will use two sens...

Really don't have any background in Programming...

So what made you pick a thesis in a topic you know nothing about. Will you be graduating in that?

If you don't mind blocking, you could just use "vw_wait_rx", or just use "vw_get_message" as you've shown.

so it is Arduino compatible but I saw some where else in the forums that there's more than one version of the bootloader.

Correct.

Bonjour,
Moi je passerais par un PCF8575, qui permet d'avoir 16 entrées/sorties numériques commandées via I2C.

it was a PRE-installed bootloader from MAKE: I bought it at Radio Shack.

hmmmm, now you got me wondering. let me zip on over to the makershed web site and see what they have.

Reverse Engineering the Propel ExecuHeli IR Protocol

Posted: 22 Jan 2013 01:00 AM PST

IndoorHeliProtocols

Here's a reverse engineering project that is instructive re: how to parse out several channels of IR commands issued to control an indoor helicopter.

From PetaVolt, via Hack A Day:

After seeing all of the Syma 107′s hacked I thought I would try to decode the IR protocol on my Propel ExecuHeli. Here are my findings.

For accuracy purposes I decided to find the signal on the controller board. I traced the IR LEDs through a transistor to pin 6 of the micro.

Unfortunately, there are no markings of any kind on the micro. It looks like it was manufactured without them.

Before digging into the protocol I thought I would have a look at what frequency the data is modulated at for the three different channels….

bueno la verdad no tengo opción de cambiar de cámara ademas aun que el espectro en su mayoría es el visible y un poco mas, por otro lado ocupar una cámara convencional no me sirve por el modo en que se capturan y almacenan las imágenes, así que por eso...

RGB Lamp with Wireless Controls

Posted: 22 Jan 2013 12:00 AM PST

RGB Lamp

Here's an assignable RGB LED strip lamp project that can be controlled wirelessly by dragging values across a window. Another great project from Miguel Ángel de Frutos Carro:

Shows the operation of an RGB lamp using a digital LED strip. After activating the bluetooth, open the application to control the lamp. The program shows a hue palette divided into 30 rods: one for each LED from the strip. Click and drag the mouse cursor to make your own patterns. Clicking on a rod while the spacebar is pressed removes the color (switch off this led).

Part list:

wooden support (optional),

RGB digitally-addressable LED strip (from Adafruit or Pololu),

microcontroller (arduino pro mini, for example),

Bluetooth .OR. Xbee .OR. an USB wire.
