This circuit uses the Buck/Boost Converter circuit for typically for use in a lab bench power supply. It features both adjustable voltage AND current using potentiometers.
Without a buck/boost converter,a computer power supply can only provide a 3.3V, 5V and 12 supply lines. With the buck/boost converter created with the aid of a 555 timer, adjustable voltage is allowed. A simple transistor is us...
This PCB is designed to drive five strips with WS2812B LEDs (or their variants) along with a Raspberry Pi (any version) from a single ATX power supply unit.
The five 5V ATX power rails are distributed to the five LED strips. While the data is forwarded between the strips.
The data path starts at the Raspberry Pi, which is connected to the first LED strip. From the end of the firs...
