Here is my first attempt at combining a couple PCBs and tying in the power together. There will most likely be some changes. I am etching this board tonight to mess with and see how the shared power works out.

Each circuit individually has been verified by its designer and DIY communities.

What is is?

It is a combination of 3 PCBs made by other people. I do not take any credit for making these designs individually, I just combined them for a neat/clean build.

What circuits are they?

• A basic 1hHz audio oscillator with a symmetry adjustment designed by R.G. Keen. I will be addig a DPDT toggle to switch between input jack or an audio probe.
• A charge pump / voltage inverter that can supply +9v -9v +12v +15v +18v designed and laid out by Madbean.
• Headphone amplifier designed by JMK Pedals.

Whats left?

I have an order of some parts I am waiting for but I am thinking of building this in a 1590BB so its not to large and takes up to much space on the bench.
