    0-30 Vdc Stabilized Power Supply

    The best way to print it out correctly is to make some test prints to find the correct ratio. Take a part with fixed dimensions (like an IC) and try to fit it on the print out paper. Then change accordingly the ratio (resize scale) to achieve the correct dimensions. It is better to use a program...

    Lost with Ground, +15, -15 and 0 volts

    Things are easy, don't be confuzed. ;) When you have +/-15V and ground (0V) that means that if you measure across ground and +15 you will get +15V reading and if you measure across ground and -15 you will get -15V reading if you don't move the test probe that was to the ground. These are...
