Pedal Power supply "Spyder" 8 output

I built this power supply because i didnt feel like spending 100-200 bucks for something i knew i could build myself. This project really kicked off my building days. I started with the design i found here:

http://www.geofex.com/Article_Folders/Spyder/Spyder.htm

It is a pretty simple isolated, regulated 9vdc power supply with eight outputs all rated at 300ma. This allows you to run many pedals off each output if needed. Similar power supplies' outputs are only rated for 20-100ma.

The short and skinny is that this power supply takes in 8 AC leads, runs then through their own bridge rectifiers, power regulators and filters, and then each has their own standard DC output.

For the transformer i picked up a great offering from Ted Weber. Part # WPDLXFMR-1

This transformer, while a bit on the large side, gives you all the outputs you need for this build, plus an extra 9vAC 2A output that you could use to power a pedal that requires AC power. ( i just left this unconnected).

I pick up all my supplies from pedalpartsplus.com
They do some great powdercoating at low cost which is nice to have your enclosure show up ready to go and dry.

By no means did i optimize this build for space. Id say it has the same footprint as the VooDooLabs power supply, but its about twice as think. And as opposed to the voodoo supply, which is about 160 bucks, this thing cost me 50 to make.

As you can see the transformer takes up a bit of space in the enclosure. Youre gonna need a drill press, or a very strong and steady hand to drill the enclosure. For the AC power jack, i used a computer style panel jack from Mouser. I drilled a few large holes for the cut out, and then just nipped around until the jack would fit. This was a real pain in the ass as i did not have legit metal nippers. Prob as easier design would have been to use a hard mount AC cable with a strain relief holder on the chassis. I just like the idea of being able to break the whole thing down with no cable sticking out.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

This board was from Radio Shack and cut down to the right size.  All of the leads you can see are the actual component leads…no other wires were used.

 

 

 

 

 

 

 

 

 

 

 

 

 

These board mount wire terminals worked out great. I bought them on a whim…but really it was much easier to manager the transformer wires this way.

 

 

 

 

 

 

 

 

 

 

I have never been a huge fan of these black isolated DC jacks..i have used them on everything…but i have always been a fan of the metal kind.

 

 

 

 

 

 

 

 

 

 

 
To this day i still have not trimmed the leads on the transformer! I was going to, but i got so excited to finish, once i found the box was working perfectly, i just jammed everything in and screwed on the bottom plate:

 

 

WHAT YOU CAN’T SEE IN THE PHOTOS THAT YOU SHOULD KNOW:

 

1.) The AC jack has a chassis mount grounding point for the earth ground….this is a MUST!

2.) The breadboard is supported on two long bolts that act as stand offs.  The final version also has electrical tape covering the backside of the board where all the solder points are. ( dont want anyhting shorting out!!)

3.) The LED was just wire in parallel with one of the outputs.  I was thinking it would be cool to have 8 leds connected in series to each input, so that a light would come on whenever a jack was connected…in the end that was pointless (like the traction control warning light on the dash of my car) and was going to take two much time.
