12 volt power supply (7812)

Posted on Apr 29, 2012

Please operate caution when building this power supply. It is run on standard 117 ac current - and under the right circumstances 117 ac can kill you. Use a plastic enclosure if possible to decrease chances of short-circuiting.

Don`t use the power supply if it`s wet, and never run it without the specified fuse. all resistors are 5 or 10 percent tolerance, 1/4-watt all capacitors are 10 percent tolerance
