The Lightchaser

I'll let the video do the talking about the history and cut to the chase - this is a kinda not-so-tough shell for a slab pinewood derby car. To every interpretation of the rules I can find, it is 100% race-legal. I did not fully document this build as I did not intent to share it initially, so I'll share what I can here. If you promise not to judge me for my timeline, I've included the F3D as well 😁 WHAT YOU'LL NEED:1x BSA Pinewood Derby kit, cut flat to ~½" (12-13mm) thick~180mm segment of 5mm RGB-IC COB LEDs (Ali)1x Wemos D1 Mini v3 (Ali)1x USB-C TP4056 (Ali)1x 6mm micro slide switch (Amazon)1x 952540 3.7V LiPo Battery (Amazon)You can go smaller if you want, but this lasted all day.Some screws (Amazon)2x M2.6x5 Self-tapping (sides)2x M2.3x8 Self-tapping (D1)Two M2x3 bolts and nutsSome ½" VHB tape and Adhesive (CA/E6000)HeatshrinkOptional - JST1.25 2 pin connectors for the battery, JST 3 pin for the LED stripOptional - some wire harness tapevery dry Transparen
