The project is presented to the operating system as USB joystick with 4 directional buttons and 8 general purpose buttons as the interface offers 12 digital inputs.
With minimal electronic knowledge and even cheaper cost, the project aims to create a universal solar power charger with the option of changing the panel whenever desired.
A glass test tube case is used to fit this single digit Nixie clock using minimal component count and without the difficulty of obtaining high voltage transformers & transistors, inductors, and driver ICs.
