As any electronics geek that is serious about his hobby, i have my own ‘home lab’. most of the stuff was bought for cheap in a broken state. stuff either gets torn down for parts or, if they are useful, restored to working order. Over the years i have amassed a serious collection of test equipment, and the collection is recycled ever so often when newer generations equipment come in and older equipment goes out the door.
