(Archive of: http://www.thing-a-day2.com/2008/02/28/day-28-thing-28-charley-plexed-display/) 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 27: Thing 27: The last of the 4 led arrays
(Archive of: http://www.thing-a-day2.com/2008/02/27/day-27-thing-27-the-last-of-the-4-led-arrays/) And then there were 4. Since this is finally the end of this particular resin. I also went to get the right casting resin. Now to wire them up….
Day 25: Thing 25: AntiSocial(ism)
(Archive of: http://www.thing-a-day2.com/2008/02/25/day-25-thing-25-antisocialism/) 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)
(Archive of: http://www.thing-a-day2.com/2008/02/24/day-24-thing-24-mouse-whiskers-touch-sensor/) 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 21: Thing 21 — Fred 644 (an attempt to port Arduino to another processor)
(Archive of: http://www.thing-a-day2.com/2008/02/21/day-21-thing-21-fred-644-an-attempt-to-port-arduino-to-another-processor/ ) I wound up on the bus for much of the day so I took my laptop and ported the arduino “Core” to atmel’s Mega644 which has 4 times the memory of the new arduino as well as almost twice the number of pins avaliable. When I got to the bootloader I… Read more »
Day 19: Thing 19: Bead Work LED array
(Archive of: http://www.thing-a-day2.com/2008/02/19/day-19-thing-19-bead-work-led-array/) I think this takes the jewelry wire influence a bit far. I used a set of glass beads to space an insulate the array wires. In the end it was almost too pretty to embedd in the plastic. These are getting amazingly tedious and I am dissapointed in the resin that I… Read more »
Day 18: Thing 18: CD Hole Based circuit board.
(Archive of: http://www.thing-a-day2.com/2008/02/18/day-18-thing-18-cd-hole-based-circuit-board/) 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
(Archive of: http://www.thing-a-day2.com/2008/02/17/day-17-thing-17-soldering-iron-timer-redux/) 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 »
Day 16: Thing 16: Headbucket Headlights (more things that go blink in the night)
(Archive of: http://www.thing-a-day2.com/2008/02/16/day-16-thing-16-headbucket-headlights-more-things-that-go-blink-in-the-night/) I went to the hardware store to replace the tip on my new Weller soldering iron after discovering that Radio Shack did not have a suitable one. At radio shack I picked up two 1100 mcd leds. On the way back I went to the art supply store to see if they… Read more »
Day 15: Thing 15: 8×8 Led Array Panel (Another thing that Goes Blink in the Night).
(Archive of: http://www.thing-a-day2.com/2008/02/15/day-15-thing-15-8×8-led-array-panel-another-thing-that-goes-blink-in-the-night/) Yesterday I went to Tap Plastics and bought some resin after working on the programmer (yesterday’s thing). At dinner last night (which saved me from pulling my hair out for the entire evening trying to get virtual pc to flash the xbee modules from my mac) I was complaining that I have… Read more »
