This is a **fully functional 555 timer** project using publicly available bipolar transistors.
The project uses 24 transistors. The resistance values are taken from the datasheet and are slightly shifted towards the more accessible series of values.
There are three test points.
The PCB design process can be...
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...
