I am planning a movie set which will contain old circuit boards from TVs, VCR's and other old electronics. The plan is to go to several Goodwill stores and buy up all of the TV's and such that they have, open them up and integrate them into the set. There is an electrical danger here due to charges still present on large capacitors. What is the best way to quickly and effectively remove these charges? Dunking these devices in a salt water bath seems like a good idea (we do not need for these devices to work.) If so, are there things we need to be aware of? If not, is there a better recommendation?
We will be getting around 60 items, so finding and discharging all of the capacitors individually could be a big problem.
