This covers the tedious, but worthy task of creating 90 marine-grade "flexible bus bars". All are made of 4x 80mm 10awg wires with a tested final resistance of 0.11 mΩ resistance, compared to the battery cells' 0.21 mΩ resistance!
This is a very repetitive video, so I did my best to edit it in a fun way. Just the same, I wanted to get across the tremendous amount of time this stage of the project took. This video had well over 20 hours of raw footage! So happy to have this done, and looking forward to starting to assemble the packs in the next video.

![Lightning Rod Tip Shape; Good Blunts And Bad Points - Ep. 125
For decades, the recommended shape of a lightning rod was to be a sharp point. That was wrong, and blunt tips turned out to be much better lightning rods.
This video explains why that is the case.

![Ep. 92 - The Motor Spins!
Wow, ok, so this is a lot! It took a LOT more work than expected, but the motor is finally under my own control!
The Kelly KLS-72100N, Golden Motor 10kw BLDC, and my own home brew (with your help!) arduino-based helm controls are all talking and working together. Its been a slog, but holy moly have I ever learned a lot. ^_^
We use MCP4725 12-bit DACs to send voltages to the controller, and a TI ULN2003a Darlington transistor array to flip the switches going to the controller. I also chase down a voltage issue that turns out to be a really dumb oops on my side.
