Showing off my Zemismart motorized curtains opening up in the morning. In the background you can see the Sunsetter Somfy motorized shade on the balcony closing automatically to keep the morning sun out.

Quite possibly the best film ever produced. Twenty-five action-packed minutes of high-energy (pun intended) transmission line science. "I give this video 3dB" - Gary Schwartz

A very simple little circuit that uses a 555 timer to generate a PWM signal to control the speed of a motor. The 555 output (pin 3) drives a IRF520 N-Channel MOSFET that controls the motor.

Just a lab assignment for ELEN126 - Digital Techniques. The circuit is comprised of four 74LS76 JK flip-flops, several AND gates, a 74LS47 BCD to Seven-segment decoder, and a giant 7-segment LED display. The clock is generated by a simple 555 timer circuit .
