The Lilypad Arduino sewn in, showing the LEDs on the desk as well as the spool of conductive thread.
Arduino Micro with 2 Adafruit PIR motion sensors. The PermaProto board fits *almost* perfectly in the project box, a very slight amount of dremel tool work gets a perfect fit. The Micro is very low profile so it fits fine with the PIR unit.
Arduino with game controller buttons triggering MIDI shield and running output through an amplifier to old Apple speakers. 3D Printed faceplate for buttons and speaker jacks. Neopixel changes colors when a button is pressed.

Connecting an Apple II keyboard to a computer with USB is surprisingly easy with a Teensy board. The Apple II uses an ASCII keyboard, which means that rather than returning scan codes, it returns a 7-bit ASCII value. This also means you can't read the state of modifier keys like shift or control independently. The Apple II keyboard in particular doesn't even support lower-case letters (though I've made a bit of a hack for this). They even re-use a couple alpha keys for other characters, so shift-P makes @ and shift-N makes ^. Other late 70s/early 80s home computers like the TRS-80 had a really simple layout like the Apple II's (though the TRS-80 had all four arrow keys but no Control key). I may have to try out adapting some other weird old home computers as USB keyboards -- the C-64 seems like it would be a good shape/size for that. (from afiler.com)
Arduino (Teensyduino) code is available at github.com/afiler/keyduino.
An arduino-based hangman prototype that uses a 16x2 LCD display, a potentiometer to scroll through the letters, button to select and speaker for sounds. Now to build a box!
So I got the sparkfun LSM303 breakout board working last night. Trouble is the I2C bus needs not higher than 1.8v logic levels to work properly.
The level shifter is capable of doing this, but it needs a 1.8v supply to operate, hence the white wire tapping it off the breakout board.
(The two yellow wires are due to the library pinout of the arduino nano board being bad)

Base board, without printed board layout. This is the pin set AFTER the chip has been bootloaded, otherwise you need pins running to the 3rd, 4th, and 5th pins up from the bottom right.

I know everyone has done this before. RFID and arduino that is. But looking at the example code it looks like the antenna is always in receive mode. I am not sure how this affects the life of the chip / reader but I thought of adding a way to detect human presence before activating the receiver.
I found some little IR heat detector (here: www.allelectronics.com/make-a-store/item/IRD-10/INFRARED-... and tossed together some analog read code and viola. Now when the IR detector detects over a certain variable heat temp it activates the RFID reader.
I will post the code and write up on my blog.

PCBs for a combined magnetometer and/or cloud detector.
Magnetic field measurements are taken from a Stefan-Mayer FLC100 sensor. Cloud detection is by measuring the 'sky' temperature. Low temperatures suggest clear skies and higher temperatures indicate the presence of cloud. A humidity sensor is also fitted to help predict the clear sky and cloudy sky temperatures. The Embedded Adventures lightning sensor module can also be fitted.

the faint glow on the led is infra red light, invisible to the eye, but visible to the sensor in my camera.
Here I'm using the arduino to control the dvd player. I just need play/pause and the dv->out button.

Arduino clone with on-board DS1307 real-time clock. The layout is designed for easy assembly and maximum compatibility with the Arduino Uno, with additional functionality being compatible with the Arduino Mega2560. The auxiliary power connector and optional LM61 temperature sensor are not fitted on this board.

We taught a workshop on how to create interactive art with the Arduino platform at the Mill Valley Library on October 24, 2015.
We showed 9 students how to make lights blink, sounds play, motors move, and how to add more color with neopixel LEDs, as described in this online guide we created for the workshop:
At the end of the workshop, we asked participants if they would like to this again, and the answer was a resounding yes! Participants told us they learned a lot from this workshop and would not only come back for future workshops, but also recommend this program to their friends.
Instructors for this workshop were Donald Day and Fabrice Florin, with support from Jean Bolte and her daughter Natalie. We are all members of Pataphysical Studios, the art collective behind the ‘Pataphysical Slot Machine’, our poetic oracle.
Come visit the exhibit this month! We’re open every Saturday and Sunday in October, from 1 to 5pm, in the downstairs conference room of the Mill Valley Library.
Special thanks to the Mill Valley Library and the Friends of the Library for making these workshops possible — especially Kristen Clarke, who helped us get the Arduino parts and set up for the workshop.
