Re: Testing unit idea

 

I use an ESP32 dev board like this one on Amazon for this purpose:

I have it permanently stuck in a bread board along with a breakout cable for a 10-pin IDC as shown in this photo:

I connect the appropriate pins of the MCU to the appropriate ribbon cable pins and use the attached script to control the relays from my lab computer via the USB serial link.

Testing filter boards would be very easy if we had a nice widget that had simple controller and an 12c socket ribbon cable plugged into to turn filter banks on and off.
Would make tweaking toroids easier for me if rig was not needed. I use SA or signal generator.
Maybe build on bread board ??
Build a few and loan them out as needed.
Just a thought, unfortunately I am not much on designing nor programming.
