Keep away from dirtiness – keep away from mess,
Don’t get into doin’ things rather-more-or-less!

Microcontroller modules for the ambitious:

    

The digital analog computer -- wire as programming language ...

It's five times better business than Linux- or C++-drill ...

The digital analog computer with an auxiliary troubleshooting unit on top (will be mounted only during bring-up and for troubleshooting tough dogs) . . .

 

All-in-One (AiO) Trainers:

Why tinkering with wires, when one can have all together (so that it will not fall apart??

Making good use of inexpensive small tablets...

         

Sometimes, the simplest will be the best: toggle switches to provide a test stimulus and LEDs or the like to observe the response:
