After several years of searching, I finally got my hands on a working ASR33 Teletype machine for a decent price. The only problem is that I now have to figure out to get it shipped from Alberta! This baby will be used with the Mod 80 that I have been restoring.

I have a Commodore 16 and a Commodore Plus/4 that do not work. These are notorious for failing due to some of the chips overheating. I've tried getting these two to work without success thus far. Since I don't have access to a working machine to test which chips are working and which ones are not, I decided to build a test unit using an Arduino UNO to at least eliminate a few of the possibilities. This is what I came up with. It function is to test the C16 and Plus/4 PLA (Programmable Logic Array) and ROM chips. Now that the hardware piece is finished, it is time to do the coding.
I used to have one of those La Crosse weather stations, however my rain gauge stopped working, and eventually, my temperature sensor died as well. This is the second time that happened, so I decided to try something completely different.
I purchased a SparkFun Weather Shield and hacked some of my old La Crosse weather instruments from my dead weather station to make a personal weather station using an Arduino, an Electric Imp. You can now see my weather on Weather Underground. I even went so far as constructing my own Stevenson enclosure for my weather station. |
