After a very rough year in my personal life I am finally able to settle back into my own place and start doing what I enjoy and that is tinkering. I had started the $50 Robot last year and had gotten as far as assembling the control unit. Last night I was going over the work I had done and found a number of bad or missing connections. I guess mixing trying to solder a robot brain and a bad relationship is never a good thing. Anyway, my question is, I'm thinking about disassembling the whole thing and starting over. Once I desolder the components, is it advisable to use them again or should I just buy new components?
