If you own any type of TI calculator (82, 83, 83+, 86, 89, 92, etc.), you may not know that it can do a lot more than math! You can build a robot (http://smallrobot.com), collect data like distance, velocity and acceleration (http://www.eaiusa.com/mo__texas__instruments__calculators__CBL-CBR.htm) or make cool games in TI-Basic or assembly (Motorola 68K or Z80--depending on your device.) I started on http://ticalc.org, so if you find this message interesting, you may want to check it out. They have games, programming and hardware tutorials, and news. So, any other calcaholics out there?
