I was just thinking what would be some easy common household items that could act as pcb substrates for TH. Anyone used anything like cardboard, thick paper, plastic(eek!), etc?
I have some 100wt paper that I was thinking possibly could work for simple TH circuits without too much difficultly and wouldn't burn under an iron. Of course it wouldn't beat a protoboard/perfboard or pcb but for quick one-offs of simple circuits it might do the job.
