The tightest constraint in this build has to be running a full addressable setup off a small battery, and the maker handled it by powering everything from a 3A phone power bank. For me that is the boldest call here: a 16.4 foot strip with 300 pixels at 60 per meter, plus a flexible LED panel, all fed from a pocket-sized bank. It clearly works, but I do wonder how much headroom is left when the white strobe flashes kick in at full brightness.
The layout is nicely thought out. A WS2812B strip with SMD 5050 RGB pixels runs along the steering stem, and a programmable flexible panel with individually addressable pixels sits on the bottom of the stem. The strip is IP67 waterproof and runs on 5V, which seems like a sensible spec for something that lives outdoors on a scooter. The maker says the whole point is being seen while riding, and the demo in a darkened room backs that up: the lights cycle between multicolored animations and bright white strobes that light up the whole room.
Control comes from a GLEDOPTO ESP32 mini strip controller running WLED, with a microphone sound mode available. The maker built a playlist that rotates favorite presets for 60 seconds each, so the scooter keeps changing its look without any fiddling. That seems like a smart way to show off a range of effects.
The little storage bag with keys hanging under the handlebars is a charming touch. The maker reports plenty of compliments while riding and says the effect looks far better in person than on camera, which I can easily believe.
