I was interested in seeing what could be whipped up quickly under conditions where you can’t buy commercial gear any more.

Lots of possibilities of using HF for data handling, old cell phones re purposed to create local networks, wifi routers to create a local data network..etc

Plus, the cheap little boards I made can be used to control equipment located remotely by just adding a bit of code.

It’s a hobby that might come in handy some day.

I envy you ... skills such as yours (being able to build from scratch, program, etc..) are rapidly becoming a lost art in the amateur radio community.

I can do basic restores of older tube equipment but this newer stuff, forget it. Specially the surface mount stuff. Probably just as well, the arthritis in my hands is getting bad enough that I struggle to solder on a PL-259 half the time.
