Made some headway with the ripple tank user interface electronics...
The mini screen will display a rotary encoder menu with digital HIGH & LOW and current for the electromagnet.
It was quite a tight fit making the connections on that 1/2-breadboard. I still have to squeeze three more on there for the electromagnet power, ground and signal...
Unfortunately, I purchased the wrong flex cable connector for the screen, so I wasn't able to power it up yet. I ordered the correct one and now just waiting for that to come with the mail.
I really like Adafruit boards and controllers for this kind of visible hardware project. Most of them are on black & white screenprints, rather than the usual PCB ugly green. They cost generally twice as much as the cheap eBay versions, but they're made in USA and with excellent support.
This will all just slide into the section of 80/20 above the ripple generator nice and tidy...
