Self-described know-how fanatic and bike owner Luca Schultz has turned his most popular mode of transportation in to a cellular monitor — by turning considered one of its wheels right into a Espressif ESP32-powered programmable persistence of imaginative and prescient (POV) show.
“That is my subsequent technology of motorcycle POV shows with prolonged performance, a extra polished design and a better user-experience,” Schultz writes of the BikeBeamer, which builds on his earlier bkpvdsply venture. “BikeBeamer produces stunning full-color pictures and animations proper in your bike spokes. Able to displaying over 16.9 million colours in its 70cm [around 27.6″] large round canvas, it is positive to look gorgeous with every thing it shows.”
The BikeBeamer relies on persistence of imaginative and prescient, the impact whereby rapidly-moving lights “smear” throughout your view — that means {that a} easy LED swung rapidly sufficient will seem to attract a line. Add some extra LEDs and management when every is illuminated, and you may make photos seem — which is what BikeBeamer does, providing a comparatively excessive decision through the use of a complete of 256 high-brightness RGB LEDs per wheel cut up throughout 4 parts to cut back the rotational velocity required for a secure picture.
The customized BikeBeamer circuit board performs host to an Espressif ESP32 microcontroller module, which makes use of its Wi-Fi radio to supply the “beamer” a part of the identify: a easy net interface that permits you to add a picture and convert it for show on the BikeBeamer. “BikeBeamer is a ardour venture of mine into which numerous hours, to not say weekends went,” Schultz says of the venture. “I am actually proud of the way it has turned out and love the by no means ending first time reactions of individuals when driving round with it.”

Schultz might provide a “small manufacturing run” sooner or later, the maker has mentioned, priced at €20 (round $22) for a naked PCB, €40 (round $43) for a partial equipment, €120 (round $130) for an entire equipment, €130 (round $141) to incorporate a case, €250 (round $271) assembled, and €260 (round $282) assembled-with-case.
