Hi,
I’m new to the forum, and looking for some info and help for my project. I’m a guitarist myself and facing the problem as many others do, powering bunch of hungry pedals from one power supply on the pedal board.
What I would like to do is regulated power supply with isolated outputs to avoid ground loops, using a torodial transformer with multiple secondaries, and I want that its totally hum free and clean.
Why I want to build it? It’s only a power supply. Because what is currently on the market costs 200$ + with decent quality, and most of them are underrated with mA of current for my needs.
Then I need to pack it to very compact enclosure e.g. (6" x 3.4"x 1.75")
I need 4 rails with 12V and one with 9V 400ma each.
I drew schematic with Eagle, but I'm a little lost, I dont know how to make 5 rails together, and create simple PCB layout, with one or 2 layers.
Can someone help me with this? Also comments on the schematics are more then welcome.
I'm not expecting that someone will draw me PCB for free, but we could talk about if someone have time to do it I'm willing to pay for the effort.
Thanks
