Pseudonymous maker “n°Storage” is in search of folks desperate to flex their expertise at surface-mount machine (SMD) soldering — with a chunk of “versatile PCB origami” festooned with 80 RGB LEDs below the management of an exterior machine.
“FlexiBall is a modular PCB origami [in the shape of an] icosidodecahedron,” n°Storage explains of the bizarre soldering problem. “It has twenty versatile PCBs of triangular form. Every PCB is similar and has 4 WS2812B-2020 LEDs in serial. As soon as these twenty triangular faces are related with soldering iron they kinds twelve hole pentagonal-faces. So FlexiBall is an icosidodecahedron.”
As soon as you’ve got soldered 80 LEDs to twenty of those compact triangular boards, you can also make your personal FlexiBall. (📷: n°Storage)
Every of the roughly-triangular components within the equipment holds 4 LEDs — one at every level and a fourth within the center — with two surface-mount capacitors per board. Soldering every board up, then is not an excessive amount of of a problem — however there are 20 boards in complete, and the versatile PCB substrate means overlong heating can render a board ineffective.
“This equipment serves as a superb train to do SMD soldering,” n°Storage claims. “It challenges your ability and your endurance. Be able to desolder if issues go improper. The conventional third hand [PCB stand] shouldn’t be really useful as a result of the enamel of its clip makes the versatile PCB ugly. In case you are utilizing a sizzling gun and solder paste, use the helper [with] a metal base with magnetic pillars.”
The FlexiBall equipment, which requires an exterior microcontroller related over a versatile printed circuit (FPC) cable, is out there to order on n°Storage’s Tindie retailer at $36; those that do not fancy the problem can order one pre-assembled for an extra $60.
