I only won the cup for innovative construction!
@M0YNG Well done! Looks like some interesting stuff was on display.
@bamfic it's what I won the cup for!
It's a box containing 4 18680 lithium cells, and some models to safely charge them from a solar panel, and regulate the output voltage to keep my radio safe.
I got bored of carrying heavy lead batteries when operating portable, this is my current solution.
Ha, it's not complex enough to have software 🤓
I've blogged about a previous version, and may well write another post about this, when I get a chance.
Hopefully this link works...
@M0YNG Congratulations Christopher.
@DD5CF_G1ZOS thanks! It was a nice surprise
