Boo! Need a hand?

Unless you can solve the shortage of some general ICs and supply chain issues, probably not much to be done on it. I've paused development since every time I go to do a release candidate hardware build run a bunch of components are on half-year backorders. So I'll re-spec them or otherwise change the design, test things, get back to release candidate state and bam, same nonsense.

It's a pretty complex safety critical thing, so it has to be 100%. Can't be some Arduino with a jumper wire rats nest to a battery pack and call it good enough.

OK, can't do much about the global supply chain in my current role as non-King of The World 😕 Yes, I get that its safety critical and has to be 100%. I'm a Professional (Mechanical by background) Engineer and understand the difference between a prototype and a finished product.

The best thing I can suggest is just place those orders and wait the 6 months. Half a year soon disappears. For perspective there have almost been 12 half-years since this thread started.
