This week we worked on electrical practice boards with relays. I thought I knew all the things that could go wrong with them by now but I learned a few new problems. I also learned how to find more than one problem in one circuit using multiple methods of detection with my trusty dusty multi-meter.  I also learned how a transistor works and found a really cool video on them.
