Portable, Variable Power Supply

Ive been a bread board a lot lately to make electronic projects and wanted to come up with a small, portable power supply. After a bit of rummaging through my spare parts I managed to find all of the bits needed to build one!
This is a simple project but has been invaluable in powering my circuit projects. You only need a handful of parts and some basic soldering skills to make your own and if you tinker with circuits and electronics, youll find this little, portable power supply come in handy.
The power can vary from 2 volts to 25 volts and has a potentiometer to allow you to change the voltage easily. I also wanted to be able to change the ends of the testing wires for different projects so also added banana plugs to be able to swap and change.”
