Sounds like patenting an idea might end up costing me a fortune!
Im gonna try out the glue gun approach, and get hold of some epoxy resin and some potting compound and see how i get on with a trial board
I did like the diode idea but i havent been able to get one to go open circuit, so i just frantically wiggled some jumper wires up and down in the middle until i felt the conductor beneath the insulation break (open circuit) and then just connected them all over the place!
Anyone copying the design should go crazy trying to figure out how its even working!
