I've seen recently on EEVBlog (https://www.youtube.com/watch?v=LXIoZBCr3Xk&list=UU2DjFE7Xf11URZqWBigcVOQ
) a resistor decade. I knew in the very first moment, I want one, and also I know that I hate that kind of rotary switches.
So, I want to created a decade box without them. In this one, I'll use MCU, relays, relay drivers, power supply, LED or LCD display, microswitches, and so.
It will be totally over-engineered, costly thing. And it will be fun designing and building it.
