DIY Power Supply

[jyblood]

I want to build the Hammerhead Pi with a few mods. Where can I buy a good power supply with boost and regulated -5v, +5v, +12v, and -12v ?

Do you want a bench supply power from AC mains?
or something that is powered from a battery (what Voltage, type and capacity)?

What is wrong with the power supply methods in the HH?
I used them and they do work.

Check my HH build here:

Here is the power supply board tested and working for the HH. it was one of the first boards ive made so its design is not optimal or pretty but it works.

I tried to look at this but unable to open the .dip file.
What is this file and what opens it?

Its the free dip trace.

Would not be much to make a better smaller pwb. Might be good for projects to have a modular power supply that could be reused. or if there is a specific design you want send me a schematic.

Thanks. First I've heard of this one.
How about a schematic (Please)?
