Freeform electronics is the method of making circuits without a PCB, the parts are simply connected together directly or with bare wire.
I have been fascinated with it for a long time now and love the look of the bare components floating in space. In this video I go over the history of the technique, how I make it and some tips for making your own freeform circuits.
