I tried fixing the last two troublesome buttons with debouncing software, but the issues were beyond code capabilities. I dug into the problem, and they both worked after reflowing their solder joints which was great news because I thought I demolished one of the buttons during installation.
Repairing some buttons
The following connections I focused on were the potentiometer and OLED screen. I probably mounted the slide upside-down, but I'll confirm that when I'm coding. The screen was straight-up broken. I must have overtightened the screws because I found cracks in the glass, but I replaced it and got the live value to show on the screen.
Screen and potentiometer working
I designed and printed a slider to go on top of the potentiometer. It's not a particularly inspired design, but it says "Velocity" on the top, so at least it's custom. After the picture, I painted the lettering in black, and it looks much better.
Printed pot topper
The following prints were spacers for the micro USB ports and some brackets to hold the faceplate off the bottom of the lunch box. Neither were a lot of trouble, but they'll both be helpful soon, and it seemed like a good day to tidy up some of the loose ends.
Angle brackets
I drilled holes in the lunch box cover to mount my LED panels. Next, I wired them up with power at each end and data between the three units. I probably should have paid better attention to their orientation when I set them up.
Panels ready to mount
I found an excellent video about a college student who made an incredible model roller coaster, but more importantly, he outfitted it with genuine industrial controls and sensors. Industrial hardware isn't cheap, but he was given a controller and screen through the college.
The rest of the summary posts have been arranged by date.
