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 […]
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 […]
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 🙂
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 […]
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.
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.
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. […]
Here is a picture of the clock running. It is showing that the time is 2:12pm 🙂
We have a problem in our house. The youngest has a habit of waking the whole house at a time that is not pleasing to the rest of us. We put a clock in his room, but that didn’t help much because the monster child can’t read yet. As with everything I decided a technological […]
After quite some time I finally have some code that seems to decompress the message data returned from Windows Live via the DeltaSync protocol. The code is AWFUL, but the results are looking pretty good.
