Managed to test them for the first time 🎉. They held up to a few falls, as I was busy looking down trying to see the effect and lost my balance 😅.

My test code doesn't seem to handle the noisy input well, even though I limited to a single axis for forward and backwards acceleration. I would sometimes see the backwards animation flash as I moved forwards.

Also, @Phil Weasel called it with the JST-XH connector. After some rough asphalt and light jumps, the frames would occasionally reset, since I would see the startup test sequence appear. I have some JST-RCY connectors in my parts bin, so will try that next.

Plenty of notes for the list of improvements. I'm looking forward to implementing them.

Looks awesome! I expected it to be much bulkier but it looks really cool when in use.

I fear you might get the same problem with the RCY connectors. Maybe really get some JWPF ( i know, they are just my favourite 😉), they are all over the automotive world. I usually leave a small pigtail from the pcb with wire-wire connectors can then be held by a "clip" on the 3d print. This way you can also safe a bit in the total width.
