General Technical Chat

• General Technical Chat

  This is where everyone hangs out and rants and chats about whatever electronics topics that don't quite fit into the other more specific categories on this forum. Occasional off-topic stuff is ok, but generally we like to keep it electronics related, so please don't start deliberately off-topic threads.
