Psychedelic Sphere
thingiverse
This creation boasts 49 self-flashing LEDs, providing a vibrant light show without the need for LSD. The design features a USB power source, with all LEDs connected in parallel (using 2-pin flashing LEDs). Two 1N4007 diodes are utilized in series to decrease voltage. Alternative options include using standard LEDs with added current limiting resistors or implementing a LED Cube scheme for customizable sequences. The model is printed in PLA silver-grey, featuring drilled cable holes (not printable) and a column support that can be removed post-printing. Assembly involves gluing after soldering, and a new concept suggests using it as a "TV-simulator" when away from home, replicating $10 store-bought devices due to its self-flashing LEDs.
