ATmega88P microcontroller counting digits on a custom LED 7-segment display.

Can you make an iPhone out of an AVR? No. Can you get a surprising amout of functionality out of a humble 8 bit processor and a cheap touch LCD? Yes. More at rossum.posterous.com

Instead of chaining multiple guitar effects in search of a new sound, I decided to mod just one. Using an Arduino microcontroller board + digi-pot chip, I was able to add a variable gating effect to a fuzz pedal.

Now that I've figured out how to store song information in flash memory on the Arduino, I can actually play full songs. This is a little suite of Mario Brothers themes that I put together. Enjoy! The sound you're hearing is coming entirely from the motors. The song information is taken from a MIDI file that I composed. An Arduino provides the necessary commands to spin the motors at the required frequencies. Note: See my earlier video at http://www.youtube.com/watch?v=8L8hY8siUMQ Motor #2 buzzed a bit on the table this time. I'm going to find a better way to hold the motors still while still allowing them to vibrate.

Edith Kollath is a friend of mine who is at the crossroads of art and microcontroller technology. She made the most beautiful books that breathe. Besides being beautiful objects, this show is also about the TSA. On a trip home to show the books in Germany, the TSA detained her and took the books from her. The story is bizarre and strange and reflects the very weird times we live in today.

This was my first microcontroller project. These days it's a lot easier to get starter with microcontrollers with an arduino. If you're interested in microcontrollers, you should get Tom Igoe's book, "Making Things Talk".

A Video Montage of Make: Magazine's annual DIY festival in its debut at the Travis County Fairgrounds in Austin Texas, October, 2007. Footage was generously donated by Rocketboom. The next Maker Faire will be held at the San Mateo Fairgrounds on May 3rd & 4th 2008. http://www.makerfaire.com

Taken after returning from the Glade festival 2007, with the patterns I had programmed for that trip. The hat how has a button and can switch between them without needing to be reprogrammed. More info here: http://www.noodlefactory.co.uk/~nick/wu-lee/LedHat

This is a demonstration of controlling an analog meter with a microcontroller, using pulse width modulation.
