Ever had a need for a replacement or project power supply that you just can't find anywhere or costs way to much?
This instructable will teach you to take junk wall warts from thrift stores and hack the circuit to give you what you need. Not the connector but the power itself. I never pay more than a buck for one using this mod.
I have been doing electronics experimentation for decades and often find a major stumbling block for my small projects a suitable power supply.
We can very simply change a single part and "make" what we need.
Need 5 volts? 9 volts? 12.6? 13.5 or any number in between? Here is your answer.
Should cost about 1 dollar!
Here we go.
First a tiny background.
These little wall warts come in 2 styles. Switching and Linear.
We need to use switching type for this hack.
How do I tell the difference?
Linear supplies, which we don't want are usually heavy in the hand and rated input is 110 - 120 VAC 60 HZ
Switching are rated 100-240 VAC 50-60 Hz, thats what we want.
NEVER WORK ON ANY LINE OPERATED EQUIPMENT WHILE PLUGGED IN. ELECTROCUTION IS POSSIBLE AND INJURY OR DEATH MAY RESULT. BE SMART, BE CAREFUL.
