Raspberry Pi with webcam connected to LilyPad Arduino with ultrasonic rangefinder. If the rangefinder is tripped a picture is taken and sent to cloud. The Raspberry Pi usb ports are both used, so I had to make a wired serial com link between Arduino and Raspberry. The level converter is $1.95 from Sparkfun.
The rangefinder works well with the Lilypad whereas some other variations of the Arduino don't have enough current to operate it consistently.
My take on the arduino based PC ambient lighting project posted here: siliconrepublic.blogspot.com/2011/02/arduino-based-pc-amb...
I used the same embedded arduino code and wiring setup to get it working, but main difference is that I used Python code instead of Processing for the desktop client, and I used an arduino proto shield to make a compact package that I could hide on my desk. I'm still tweaking the code so that it can work with fullscreen applications like games and average all 3 monitors instead of the center, but as it is now it works really well.

I am slowly building a UAV. This is a Pandora pan/tilt head with a tiny KX131 video camera, controlled by an Arduino board.
This will be the UAV's eyes.
For fun I used the Sudden Motion Sensor on my Mac to control the servos.

Arduino with variable flashing light makes interesting sounds with Thingamagoop.
Knobs controls speed of flashing, duration of 'light on' and a randomness level to keep things interesting.
A small and simple Arduino project with a lot of the basic stuff. Digital input, analog input, digital output, LEDs, and so on. See comment for the source code.
Arduino and hiviz.com audio trigger setup for Milky Music..
There is some stuff on the experimental board, which is no longer used.. And I know, its not really nice, but it works..
Assembly instruction for audio trigger can be found on www.hiviz.com
Drop of water just before it hits the sheet of plastic.
Test with the Arduino Duemilanove microcontroller to control delay.
Now it's much easier to control the delay as i can program it from my PC.
here is a quick picture of the setup : http://www.flickr.com/photos/34463171@N04/3601835144/
Now i'm waiting for a solenoid valve for the setup so i can control the drops too and start it all with a push of a button.
Space was limited in my room so I decided long ago to remove my bed and build a lofted setup.
I do a lot of tinkering so I built in a U shaped desk that extends more or less around the full perimeter of my room with lots of space to work on things. My desktop setup lies directly underneath my bed and on the opposite side I have a soldering/electronics station.
I recently underwent a few hardware upgrades for my desktop which include a liquid cooled 6 core, 64 gb RAM custom machine and 3x 27" Achieva Shimian Korean IPS displays. These are mounted to the wall with monitor arms and can be pulled closer to the edge of the table if needed. The setup works really well for my 3d modeling and coding work.
They are also backlit by a RGB LED strip powered by an Arduino R3 and Python based client on the desktop which changes color according to the color on the screens. I find that it helps a lot with eye strain and adds a great ambiance to the room.

Our third Arduino 101 class at Tam Makers went really well. I taught this evening course with co-instructor Donald Day on Thursdays, from June 16 to 30, 2016, at the woodshop in Tam High School in Mill Valley.
We worked with an enthusiastic group of seven students, including adults with diverse backgrounds, as well as a couple high school students. Our partner Geo Monley worked both as a mentor and as a student during the hands-on sessions.
We started the class at 6pm, by giving students an overview of how circuits work. We then learned how to use a multimeter, how to solder electronics, and how to control rainbow-colored NeoPixel lights.
Students seemed to really enjoy this class and told us they learned a lot from it. Several expressed an interest in taking intermediate and advanced classes in the future. This is one of our first maker courses at Tam Makers, and we’re really happy that it is going so well; we look forward to teaching more classes in the fall.

My trolley (Lego 9v train) powered by Arduino. The trolley moves back and forth along the track with a several second wait at each train platform. Version 1 of the trolley was controlled by Mindstorms EV3 and a normal Lego regulator. The only issue was the trolley would not start from time to time (maybe once every hour or two on the worst day). The Lego regulator supplies 3V and 4.2V as the lowest 2 settings (at least the 2 Lego regulators that I tested) and nothing in between. At 3V, the trolley would have problems and at 4.2V it would always start but it was travelling like a run-away freight train. In version 2, the arduino is supplying the power to the 9v track and is able to select the voltage anywhere between 2.2ish Volts and 5 Volts with a 5V power supply and this particular motor controller. It can supply up to 1.2A (the trolley uses .1A at steady state and according to googled sources peaks at .4A). Currently I'm running it around 2.4V and it seems to be starting just fine. However, I have been unable to do long term testing yet because the sensors (reed switches) are not reliably detecting the trolley so it ends up in the last track section which is plastic track (to avoid the train grinding it's motor at the stop). The actual trolley car was created by Nate.

I am making an Arduino course for hipsters, instead of looking at what you learn, I am going to concentrate in what people think about themselves, establish an indie relationship to the world of electronics, portratit electrons as Emo-children, help the bohemian soul to embrace complex concepts that go beyond drinking wine while listening to Coldplay ... and all of this while only wearing B&W clothes.
This is the cover to the notebook for the course that will take place on April 28th at STPLN, in Malmo, Sweden.
Arduino hack: light sensor programmed to indicate light level using 3 LEDs - Picture by Tristan Nitot
Using a second arduino as a graphics card generating B/W video out (PAL or NTSC) thanks to the amazing Batsocks code as used in the TellyMate shield. (See recent blog post.)
This makes me very, very happy! Apart from the duinos there are only FOUR components in there -- 2 diodes and 2 resistors.

UPDATE (11/2013) By now, the Arduino Leonardo and many other ATMega32u4 based clones are widely available. When loaded with the Leonardo bootloader they identify themselves as a USB keyboard/mouse. You can easily access these features using the provided libraries: arduino.cc/en/Reference/MouseKeyboard
UPDATE (2/13/2012): Spark Fun publishes a tutorial for an Arduino keyboard. OK, so they cheat a little by using a variant of the ATmega chip, but it is inexpensive and works with the Arduino software, so I think I'll have to give it a try.
UPDATE: Apparently new Arduinos are being release very soon which already include the ability to mimic a keyboard or mouse out of the box! Check out the official announcement!
UPDATE: Another Arduino/USB keyboard project just appeared I wonder if it can be generalized to any ATMega328.
UPDATE: check this out us.cactii.net/~bb/morsekey/ looks like it could be another method for turning any arduino into a usb keyboard!
Tired of waiting to find out how to program Arduino Uno to pretend that it's a keyboard?
I am.
I needed a way to interrupt a PC during boot to get to the BIOS from a remote location. In this case the BIOS works well enough over a serial port, but you can only get there by pushing a real key on a real keyboard in person. Who wants to go down to the lab every time you need to push a button!?
So I looked into recycling an old keyboard for the job: Instructables, Hacking a USB Keyboard
That's a nice enough explanation, but doesn't really get me to writing a program to press keys, never-mind let me press a key via SSH. Although it did show me how to figure out which two wires I need to connect to "press" DEL.
So I figured, I'd try a FET as switch. I started with an MPF-102 FET, but that didn't work very well. Frankly, I'm wondering what an MPF-102 is actually good at. Nothing I've found so far.
Having failed with a transistor, I tried a proper relay. That worked well but then I wondered: What would happen if I just used the suggested PN2222 transistor without the relay? And that just worked. Yay!
Then I added a MAX-232 chip which doubled as a non-USB method for programming the Arduino (an FTDI cable costs $20!, MAX232 is $1.20 or so, plus capacitors) and the lab has digi console servers which let me talk to RS232 via SSH/telnet. That's how I was talking to the console on the PC anyway.
I "stole" the wiring for the MAX232 from the Freeduino Serial.
And pressing the key is as simple as a digitalwrite HIGH for .1 seconds. I simplified one of the stock serial examples to make it interactive, and I soldered some wires to a DB-9 connector (as per the Freeduino schematic).
And it worked! Although, OSX wasn't very helpful. Every time I plugged int the keyboard to test it, it asked me to help it identify why kind of keyboard it was. And then I ran into a feedback loop when I told it to send DEL whenever it got a single character. Turns out DEL is 3 or 4 characters which each tried to send a DEL, and you get the picture.
I deployed it today, and it works perfectly! Then I see this link on Make's blog: MAKE Video audition: Google Reader pedal But *whew*, its OK. They are also only adding a different mechanical switch to a keyboard's guts, not giving you programatic control over the keyboard.
With some shift registers and a bunch of transistors, I could control the whole keyboard with no special software/drivers. In fact, it would work without the target computer ever realizing that it is being remotely operated!

PS Yes, my wiring could've been neater/cleaner, but I was trying to get something working relatively quickly. I'm very pleased with the functionality, although the appearance is admittedly sub-par.

any similarity to a test message in another photo is entirely intentional. can you guess what's coming next?
I haven't got a kitten to chase my laser pointer, so I built this instead. Using an arduino board and a few LDRs, the reverse doesn't work yet, it needs some more calibration.
