DIY Resistor Substitution Decade Box. George (our video producer!) writes –
Here’s a handy guild on how to build your own DIY Resistor Substitution Decade Box. I had seen several people online building their own, but instructions weren’t very clear. Hopefully these 50 or so pictures will help. First step – hop onto ebay, and pick up some switches. You can find them by searching for “decimal thumbwheel switch” – I think I only paid $5 for 10 of them including shipping (from china). Order up some extras – they can be used for all sorts of things – and a fun part to keep around.
