  1. I scrubbed Atmega8 package to expose what’s inside the DIP.

  2. This is simple animation (Click on it to see it) demonstrating how simple shift register works. There is a clock signal used to clock the register (rising edge) and manual switch used to push data to register. LED bar indicates how data is shifting.

  3. This UV PCB exposure was built from flat-bet scanner and three 8W UV light tubes. Exposure time is about 2 minutes and 20 seconds.
