Power supply
Just a quick update on the DDS Function generator project. I’ve just finished designing and laying out the power supply module. It’s a very basic design that uses 4 linear regulators to output 15V, 5V, GND, -5V, -15V. It’s not the most efficient design but because the system will not be using huge amounts of power, I think it’ll serve quite well, and because it’s a module if heat does becomes a issue it can always be replaced with a more efficient switch-mode supply.
Above is a quick 3D rendering of what it looks like at the moment. For scale, it’ll easily fit in the palm or your hand.
