This is yet another project born of necessity. It’s a simple circuit, but does exactly what it’s designed to do – dim LED lights or control the speed of 12V DC motors. The circuit uses PWM to regulate ...

This handy circuit can be used as a speed controller for a 12V motor rated up to 5A (continuous) or as a dimmer for a 12V halogen or standard incandescent lamp rated up to 50W. It varies the power to ...

This project was created in an attempt to use 22V DC LED bars on a 12V DC source. After locating the MeanWell LDB series of buck boost drivers, I decided I wanted to ad the capability to dim the LEDs, ...

The TC665 is a System Management Bus (SMBus) PWM fan speed controller from Microchip that was developed for use with brushless DC motors. The device features FanSense™ protection against fan failure ...

PWM or Pulse Width Modulation has generally been regarded as too complicated for PC fan speed control compared against using rheostats or linear voltage regulators such as the LM317. I present here a ...

I have a Darlington transistor to keep cool. It is a lovely chunky TIP147 in a TO247 package, attached to a PC heatsink (£6 from ebay) to get the heat out. PC heatsinks are great as they often include ...
