Automatic temperature controlled fan speed controller to cool my extruder motor. It uses a 555 timer and an opamp to generate a 25kHz PWM signal for the fan, and is mostly made from surface mount parts.
I am building a website for makers to keep track of materials and components, and to allow those components to be shared locally with other makers.

I'm a engineer and maker, and enjoy doing 3D printing and electronics projects at home. I also mentor for First Robotics and enjoy teaching others about engineering.
