Basic Voltage-Controlled Amplifier
I’ve been looking at the theoretical principles that govern the voltage-controlled amplifier (VCA) recently and came across some simple VCA designs that caught…

Differential Amplifier w/ Cathode Follower
This is a circuit designed for a classroom project whereby the instructions were to “improve” a differential amplifier circuit. The differential amplifier design…
LightBox prototype
here’s a small battery-powered guitar amp that i’ve constructed from reused parts. the housing is a busted computer power supply (some of which…
the final layout
She’s big and bulky, but you can’t ask for too much when you’re dealing with pre-printed PC boards. The 22k resistor in the…
the first of four…
This was my first attempt at building the circuit on the PC board. Unfortunately, I think I’m going to have to get a…
