Any electronics whizzes here? I have an Atera brand hot tub that I've had for years. The topside control panel sucks. It's a pcb touch pad and it's a pain to use. You have to push the little touch pad just right in order to change the temp or turn the Jets on and off. I was wondering if it is possible to build a better switch. Something like a dial or some other mechanical switch rather than the crappy touch pad. Any suggestions?
