I've finished the design of the active hybrid-dry/capacitive electrode (the electronics, PCB and mechanical parts). If there are some hardware/electronic engineers in this list, I'd like you to take a look at the schematic, or design in general. I think I have commented a lot each step, although I need to finish some section... If there is something you don't understand, or if you can see any mistake, please just contact me.
I'll finish these sections and continue with the rest of the module this week.
I'd also like to know whether you have some email list for hardware/electronic engineers, since maybe my emails bother some of you...
I hope you enjoy this as much as I do! ;)
