Hello,
I am trying to create a power bus to feed items in a modular system (I am building a modular analogue synthesizer).
Before I begin I want my power supply board to provide a stable "+12", "-12" and "GND".
I have bought a 24V power supply and I have a bunch of Voltage Regulators, one that takes +15v and gives +12v (I can cope with that, easy stuff), and one that takes in -15v and gives -12v...
Now, I think I have implemented a way of using a voltage divider to work myself some negative voltage (cause all voltage is only relative to its GND right?), but I think I am going to have a problem because I don't think my resulting GNDs are common to each other. Can anyone suggest what I might need to do to achieve this? (please see the diagram)
Many thanks, Alec
