I saw this last night, and can’t wait to try it out. http://courseweb.stthomas.edu/apthomas/SquishyCircuits/howTo.htm It would be cool if there was a nice way to make a cake that was conductive, and yet still edible….

Failure
I have been looking for this video for ages! http://blip.tv/tucs-tech-talks/an-illustrated-history-of-failure-2729174 I saw it some time ago and it was amazing. The content is great, but more importantly it show how to give a presentation using powerpoint that actually works!
JRuby, Rails and Development mode
Well, that was fun… I spent quite a bit of time today beating my head against a “memory leak” only to remember that JRuby + Rails + Development mode = very leaky. Switch to production mode and the problem goes away. A simple little Rails app with one controller and one model is all that …
Sadness doesn’t even come close
My boy is going to die soon. He has been diagnosed with a degenerative brain disorder. He is almost 4 now and we will be “lucky” if he sees 6 years old. There are is no cure. All we can do is try to keep him comfortable. I alternate between numbness and weeping. He’s such a …
Funky Clock 2 is up and running
Funky clock is installed and working really nicely 🙂 I had a little trouble with the digital inputs as the pull down resistors I used were 100K instead of 10K. Also for some reason I was unable to read port E2 at all. Once I moved that input to port C4 and replaced the resistors …
Temperature sensor
I added a LM35 temperature sensor to the unit measuring the water level in my main tanks. After a mild calibration issue (shown above) it seems to be reading very close to the actual temperature 🙂 I find it amazing how much I am enjoying having this data. Very silly 🙂
Funky Clock 2.0
Here is Funky Clock 2.0, well the processor board anyway. I have several PIC18F452 in the PLCC package, so I decided to see if I could get that working. My forth is running on it and I am implementing a new UI for the clock allowing the time to be set using a really cool …
DeltaSync HU01 decompression code released
I have released an initial version of the DeltaSync HU01 decompression routine on github. See https://github.com/dparnell/hu01 for the code It is AWFUL code, but it seems to work.
PS3
Unless you’ve been living under a rock recently you’ll know that the Playstation 3 is now wide open for home brew code. I’ve been having some fun running my own code on my PS3 🙂 The PSL1GHT wiki contains all the information necessary to set up a development environment.
More on the Funky Clock
I had another one of the LED arrays around the place and decided to see if I could drive it directly from the PIC port pins. It seems I can, and the results are much better than my much more complicated previous setup. Of course it uses up almost all of the PIC18F4550’s port pins. …
