Please operate caution when building this power supply. It is run on, I believe, 120v ac current (standard US wall outlet) - and under the right circumstances 120 ac can kill you. Use a plastic enclosure if possible to decrease chances of short-circuiting. visit page.5 volt power supply (7805) - schematic
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-wattall capacitors are 10 percent tolerance visit page.
