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.
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.
DISCRETE LINEAR REGULATOR
A discrete linear regulator with a TIP35C pass transistor. Capable of 1.86% line/load regulation and 50% efficiency. Active current limiting at 2A output current.
PHASE LOCKED LOOP EXPLORATION
Implementations of the CD4046 PLL and phase detection.
Focus on the BT139 Triac. Included in various implementations such as opto-isolation and off-line digital electronics
SWITCHING POWER SUPPLY
An attempt at building a regulated switching power supply.
PID MOTOR CONTROLLER
Using PID to regulate the speed of brushed DC motor.
LASER TRACKING SERVO
Utilizing a PID loop to have a laser pointer track the center of a solar cell several feet away.
