Introduction: Power Supply for Guitar Pedalboard
Complementing my previous project, this time more than an Instructable I just wanted to add a simple design to the pedalboard that I may someday put together.
All of my pedals depend on 9V either battery or external power supply to work. There are some products from Voodoo Labs, MXR, T Rex engineering, and others that provide several isolated 9V outputs. It shouldn’t be complicated to create something similar for much less money
I already have 5 Radioshack 12.6v 300ma PCB Mount Miniature Transformer 273-1385b (pictured). The output current is 300 mA, more than enough to power effect pedals.
The design is the direct application of the LM7809 voltage regulator and I am using SMD diode bridges MB10S.
Step 1: Using DIYLC for the Board
The design is very simple and I replicated one supply times 5. The schematic and board design are attached. Also included is a PDF file with the traces for the board a 1:1 scale and mirrored ready for PCB transfer.
The application can be downloaded from http://diy-fever.com/software/diylc/
BOM
C1, C3, C5, C7, C9: 1000uF 16V
C2, C4, C6, C8, C10: 10nF 16V
IC1, IC2, IC3, IC4, IC5: MB10S
IC6, IC7, IC8, IC9, IC10: LM7809

Step 2: Soldering Components, Putting Things Together
My next project will probably be to put together the looper and 2 of these power supplies, changing one 7809 for a 7805 to power the looper.
I shall be set after that.
