![Ep. 95 - 2 Throttles, 2 Motors, 1 Brain - DIY Helm Controls
Ive been deep into learning STM32 embedded development, and Im finally starting to come up from under the rock Ive been hiding under.
This vide is pretty technical, and probably not the most interesting. However, I wanted to make it anyway because projects are not all sparks and excitement. Working through long, slow spans of learning to do something is a real part of taking on big projects.

![Ep. 106 - Shaving My Box - Battery Prototype Pt. 2
In this video, I shave down 75mm / 3 in the port/starboard width off the battery box. Will that be enough? I dont know, and wont until the next video. With the box thinned, I finish the rebates for the vertical separators and the mid-plate.
Happy holidays!
