The following projects were made as hobbyist projects. Not required for class. This webpage is under development

Boost Converter (Without Feedback)

A voltage boosting circuit using a MOSFET and 555 timer for signal generation. The next version of this circuit will have feedback with a microprocessor to control the switching.

3 Channel PWM controller for 10W RGB LED

Two Different attempts to implement a TLC5973 three channel Pulse Width Modulation (PWM) controller. Three 10 Watt 10 ohm power resistors were used in series with 3 power MOSFETs.

Motion sensing switch for power LEDs

Three different designs to automatically turn on a power LED based on a PIR motion detector. Once triggered the light remains on for an adjustable amount of time. These circuits are used throughout my apartment.

Power LEDs

The smaller packages shown in the first two photos contain 9 LEDs, with a forward voltage of 10 Volts, and a max power of 10 Watts. The package in the in the last photo has a max power of 50 Watts, and 100 LED chips.
