Here you will find the projects I have taken on (most of which are never completed)

Dual Power Supply with 48V Phantom Power Output

Posted December 27th, 2013 by

Presented is another power supply schematic, but this time using adjustable regulators instead of the normal 78xx and 79xx series fixed voltage regulators. These typically provide lower noise output, and the output voltages can be changed by altering the values of resistors, rather than replacing the three-terminal regulators (which can be quite cumbersome).

Hi-Z to Balanced Line Level Converter

Posted December 16th, 2013 by

Presented is a schematic for a simple circuit with a high-impedance, unbalanced input suitable for an electric (or bass) guitar or some sort of piezo pickup, and balanced, line-level output suitable for use with an audio interface with an appropriate input.

Regulated Dual Power Supply

Posted December 1st, 2013 by

The first project I’ve decided to publish here is a simple dual power supply, which I use for powering audio circuits requiring such a supply. It’s pretty much a standard design, and should be suitable for low power devices (ie. don’t use it for a power amplifier or a toaster or anything).
