OV-imponator!
The hardware is designed using KiCad, and the project borrows a little layout from a previous attempt at an OV-imponator with another architecture (used "dumb" LEDs).
The imponator will consist of a circuit board shaped like the OV logo, with a regular imponator pin on the back, and a laser cut diffuser on top of the SK9822 addressable RGB LEDs. It will be connected to an external battery pack. Unlike the regular imponators, the diode plate and "driver circuit" are combined in this implementation.
Symbols and footprints not contained in the official KiCad (7.x) library should be added to the respective project-local libraries.
Komponentene koster veldig omtrentlig 100kr, og kretskortet er tolags på ca. 50 x 65 mm.
