I was inspired to build my own test bench power supply following the excellent tutorial by JumperOne. It was actually very simple to do and I didn’t get electrocuted in the process.
Now I can save on those batteries when building circuits. I’m also hoping to be able to use the +5V source to power 4 or 5 servos for a robotic arm project I am working on. I have to test the current to make sure it’s not too much or too little for the servos. Any suggestions are appreciated.
Once the black (ground), red (+5V), and yellow (+12V) wires are bundled, They are soldered to end of the binding posts.
For my next project, I might try building an AC to DC power supply using a transformer and bridge rectifier. JumperOne has a tutorial on that also!
