Build this Universal Voltage Regulator for $8.





Nothing special about this kit.
Just install all the components, watching polarity.
C1 cap may be either a 330uF or a 470uF
C2 cap has been changed from 220uF to 47uF
Mount the 7808 regulator on top of the board.
Bend the 7808 leads and then insert and mount flat,
aligning the holes of the PCB with the 7808
When installing the LEDs, note the flat edge.
The 4-40 mounting screw and nut are not included it the kit,
and may not be required, depending upon how much heat is
generated by the TO-220 voltage regulator.
