Here are some of the projects on my to-do list. I try my best to document these doings, since other people may learn from them as well. If you have a project in mind you think I should build, drop me a line.
Finished projects are on the sidebar. I’ve tried my best to make them clear, but some of them are not yet fully documented.
Current projects that should have something to post about soon:
- Roaming Robot
I’m almost finished machining the frame for this robot. It has rack and pinion steering, GPS for overall navigation, and sonar for collision avoidance. I’m hoping it will be autonomous enough to get me donuts across campus.
- Antenna Analyzer
This device uses a DDS (direct digital synthesis) chip to sweep a sine wave over a frequency range, then samples the SWR at minute points along the way and graphs this. This sort of graph is very handy for tuning antennas, since you can see in real time what each change you make does.
