Day 1: Thing 1: Midi Monster Board Design

Posted by & filed under Thing A Day 2010.

This month we have two workshops. One on interfacing Purdata with the outside world and one on programming midi devices. I designed one board that should work for both classes. I will blog a bit more about this technically later at but that was my thing for the day.

The $15 Wiring Board

Posted by & filed under Avr Development, Wiring/Arduino.

This was started out as one of my things for Thing-A-Day (2008) ( This follows my work getting the wiring software platform working on some generic mega128 boards. It is somehow related to my work on reducing the costs of the Arduino runtime to less than $4 I recently found the code for an Stk500v2… Read more »

Day 28: Thing 28: Charley plexed display

Posted by & filed under Thing A Day 2008.

(Archive of: Today I made the software for some hardware that I built a while ago. The origional question was if I got 15000 leds for next to nothing and it costs 4-15 per 8×8 array (with the 4$ solution also needing 4 to eleven additional parts) to drive them are we getting anywhere?… Read more »

Day 25: Thing 25: AntiSocial(ism)

Posted by & filed under Thing A Day 2008.

(Archive of: I went to radio shack about a month ago and bought an utrasonic distance sensor made by parallax called a ping))). I have been feeling cranky and anti social lately so I thought I should make something that didnt want to be bothered. I am considering adding an air horn for people… Read more »

Day 24: Thing 24 — Mouse Whiskers (touch sensor)

Posted by & filed under Thing A Day 2008.

(Archive of: Two weekends ago Aidan and I went to radio shack and he was looking at these $9 bug bots which have a sound sensor, two touch sensors (antennae) and 6 legs. He was very interseted in both the walking mechanism and the touch sensor. We decided that we should add one of… Read more »

Day 23: Thing 23: DELETED!!! (Button and screen)

Posted by & filed under Thing A Day 2008.

(Archive of: After the last two days of disaster I got a new board in the mail. It has one of the new atmel USB avrs on it which I would like to work with instead of the the ftdi chipset for programming avrs and arduinos. Rather than attempt to do another complicated and… Read more »

Day 20: Thing 20: Arduino on a (simm) Stick

Posted by & filed under Thing A Day 2008.

(Archive of: In response to a conversation I had with “lady ada” in which she asked me “what is an arduino?” I have been pushing the question “What isnt?”. I have a bunch of stuff that I have built around the simstick platform which I wanted to reclaim so I put a 168 on… Read more »

Day 18: Thing 18: CD Hole Based circuit board.

Posted by & filed under Thing A Day 2008.

(Archive of: I havent made a circuit board in ages. I was thinking that if I made circular pads for the leds they might make a decent reflections for the display. I made the etch mask for this out of the holes for press on cd lables and 1/8″ engineering tape. In the middle… Read more »

Day 17: Thing 17: Soldering Iron Timer Redux

Posted by & filed under Thing A Day 2008.

(Archive of: Today I really made Space and time (The appartment was getting a bit difficult to get around in). So this is a make up entry. After oxydizing the first tip on my new weller I decided it was time to build a new soldering iron timer (and one for my glue gun… Read more »
