Very happy to how our electronics board came out this year. I made just a few suggestions this year including standardizing the use of ferrules and also the use of wire tunnels. Those two suggestions went a long way.
Gotta love a clean electrical set up. We did the same thing by standardizing the material usage and cleaning up our overall setup for the electrical and pneumatics setup. We had a couple kids that wanted to do this for a couple years and we told them to run with it. Makes troubleshooting and debugging on the physical end so much easier when everything is labeled and clean.
