TRON bike lighting update.

Got a black helmet for myself and for one of my kids and did the final fit of the LED strips before the last push to get them all soldered together. Done, though after hot gluing and heat shrinking it all down, two of the ... 20 connections short out if they flex a bit, so I need to cut them open and redo. It's actually the second connection I did and also the third to last. It makes sense I would screw up near the start before I got the hang of it but near the end doesn't.

Anyway once those are fixed and showing enough durability it'll be time to VHB tape them to helmets.

I was all set to try some demo runs with ESP32-C3s I had on hand but then I noticed a variant which comes with a postage sized OLED screen so I obviously need that so it blinks each kid's name and maybe a cute bitmap design.
