Tech Class #2 will be on Feb 8th from 1pm-3pm at the Replay Foundation facility ( directions here ). If you are planning on coming there are several things you need to know! The class will be an opportunity to learn about electricity, how it powers a pinball machine, how to measure it, and how to avoid zapping yourself. You are encouraged to bring a multi-meter for the hands on portion of the class. If you don't have one, we can recommend a starter multi-meter one from Harbor Freight ( Harbor Freight Multi-meter ) or Amazon ( Amazon multi-meter ). Each class costs 5 dollars per person. This money goes to covering supplies and costs for the class. We're looking forward to seeing everyone on Feb 8th!
