ELECTRONICS

All projects shown here are focused on general electronics and are not intended to be used in an audio synthesizer environment. Do not take these designs as finished products. Some have flaws and I will explain known issues to the best of my ability.


Function Generator

Produces a sine, square, and triangle capable of +/- 10Vpp and 50mA source/sink. Sine wave THD ~2%.
Pulse output provides 0-12Vpk pulses with 70ns rise/fall times. Capable of 200mA source/sink.


Laser Tracking Servo

Utilizing a PID loop to have a laser pointer track the center of a solar cell several feet away.


Switch-Mode Power Supply

An attempt at building a regulated switching power supply.


PID Motor Controller

Using PID to regulate the speed and torque of brushed DC motor.


Discrete Linear Regulator

A discrete linear regulator utilizing a TIP35C pass transistor. Capable of 1.86% line/load regulation and 50% efficiency. Active current limiting at 2A output current.


PLL Exploration

Implementations of the CD4046 PLL and phase detection.


Triac Exploration

Focused on the BT139 Triac. Included in various implementations such as opto-isolation and off-line digital electronics
