Re: Awesome Electronics Box!
 

It was a concern at first, that's why we added the vents and extra fans. We've tested it pretty extensively and haven't had any issues (box never even gets warm). It's a combination of good circulation, operating in room temperature, and not having an overly power-hungry robot. You're right though, with enclosed electronics, heating should always be a concern.

Looks great! We did a similar thing with our control board this year, but we decided to route our wires above the pegboard in panduit tracks for easier inspection, as opposed to behind the pegboard (I'm presuming the wires are back there, as they're not visible in the video). We did not do panel-mount or color-coded andersons, just left some pigtails out for each one, and clearly labeled each with a 1-6 value. We went with six talons as opposed to your seven, but we were initially only using four and added a fifth to add more power to our lift; we still have a spare which we can swap out in just a few minutes. We mounted our polycarbonate cowling a couple of inches above the components to allow passive rather than active airflow.
