It was great – up until this point:
Thanks Alasdair 😉 No dangerous damage done except to my pride.
It was one of the ESCs which overheated and burned, but there was a lot of collateral damage, as the burning ESC means the RPi etc may well have see ~12V directly from the LiPo for a second or two; dissection planned for today to work out what if anything is salvageable.
Zoe’s autopsy showed that actually all that’s lost is a USB power cable for the PiZero, and obviously, the burning arm / ESC / motors etc. Amazing the PiZero and sensor PCB survived – I’ve got a mass of spares to it’s time to put her back together.
