Edrum PSU
12/25/2009
The Edrum Project only requires a simple power supply, I ended up just using a 12 VDC wall wart to supply the unregulated power and made a regulator PCB for the +5 and the +8 Voltage Regulators....

This PCB is the only point where the Analog supply and the digital supply grounds meet together, this will keep any "noise" in the supply lines from kreeping in....



The 4 diodes rectify the incoming voltage to DC and the Reglators provide the proper voltage levels...
The power indicator LED will also be connected to this board and the LED will be mounted on the faceplate.


Not much to this PCB either, just a simple 2 Voltage regulator PCB and some passive components....... Some spacing for Heatsinks were left in the design in case I need them later on, but from what current the whole projects draws, I should not have any problems with the regulators heating up....
