TLC5940NT Painter Board
This screen shot is an all-layer view of my TLC5940 painter board. The 1st draft featured two TLC5940s, but I decided it made the board too large. Instead, I wanted the ability to mount the painter boards around the LED’s shadow box. This should make routing all the wires much easier.
This pattern is called Row Your Boat. As one of the strips starts to get brighter, a nearby strip will join in the fading. After completing a fade cycle, they start switching colors. There is a random strobe thrown in there as well. The first 10 seconds are with a diffuser (piece of paper), the last 10 seconds are without. The final panel will use a diffuser.
Quick schematic in gschem running on OS X.
In an attempt to find a free set of schematic and PCB tools for hobby work, I looked back at gEDA. The last time I used it was when the project first started, years and years ago. I was happy to see that OS X had a set of fink packages for the gEDA suite. After figuring out how to get X11 in Leopard (since I didn’t include it when I installed 10.5) and install fink, getting gEDA going was a snap. The user jluciani in the Arduino forums has provided some free pcb footprints he has used from previous projects.
Landing on water isn’t easy. In fact, most aerospace engineers never considered it possible.

Initially I tried to get a LCD screen working with my Illuminato based Arduino. After a couple of attempts I realized two things: 1. The Iluminato is not ready for prime time. and 2. I burned out the LCD. So I decided to move on to the LCD strips I have from Sparkfun.
This morning I woke up somewhere in Southern Austria. When I looked outside my window, I found a very heavy snowfall. My local colleagues tell me that we received somewhere between 50 and 60cm of snow. That is between 10 and 20ft, based on what I can see.
Four weeks ago, I developed a rash (no, not that kind). My dermatologist (www.webmd.com) concluded it was a result of being exposed to extreme dry and cold conditions. In fewer words, I was allergic to Colorado. So, I moved from Colorado Springs back to Austin. Despite growing up in Northwest Indiana, which received significant amounts of snow fall and ridiculous below freezing temperatures, I am very warm blooded. After moving just 2 or 3 weeks ago and becoming acclimated to warm weather again, I found myself headed to Europe on a business trip.
This is my third extended visit to Europe. The previous two were in November and Januarys, respectively. Eventually I will visit Europe when I don’t need 9 layers of clothing.
The other day the question was asked “Can you sell a bag of Trash on Craigslist”? This question interested me
Not everything is free
because in Dan Ariely’s book “Predictably Irrational“, he discussed the behavior people exhibit when something is “Free.” In short, our brains actually react differently when “Free” is offered instead of a price. People quickly forget there are costs associated with anything that is “Free.”
It was quickly discovered if you actually post “I have a bag of trash,” it gets flagged. Real Fast. Not satisfied with the result, I made a post that described a bag of garbage without using those exact words. The result? Well, they surprised me. After just 12 hours, I had to take down the post because I got tired of the emails.
After a long time posting to cmiyc.com, an upgrade to Wordpress, and two physical moves I just wanted to make sure the blog still works….

Minor change in how uploads are handled (to correctly support USB). This is the only different from 96.
