Okay, this is kind of an off shoot of an old thread from several years ago. So, i guess in a way im reviving a really old thread.
Anyway, sometimes as a team involved in FIRST, one always wants to try new things, and new projects, and for most of those projects you need motor speed controllers. You cant always borrow a victor or a jaguar for these projects, and you usually dont want to buy your own. Anyway, when i was the head electrical person for my team, i would always dream of being able to make my own victor from scratch. Mostly because i thought it would be cool to have a robot in the summer, but also because it's sometimes fun to just make your own stuff.
Anyway, I've been working on an open source clone of the victors. I finally have a working prototype, and even thought it's still in need of testing, debugging, and possible improvements.... i thought some of you may benefit from me sharing it with you early anyway.
Here's some pictures, hopefully in the future i will upload a youtube video. Here's a link to the current thread dedicated to it, if you want to check the progress in the future. OH!! also remember that any version before R9 has a major design flaw having to do with the wrong part being used on the board. R9 is the only working version up to this point!!
