Another circuit with famous 555 chip. I decided to make a toy robot with blinking eyes. It is easy and fun to make.. This project is great soldering practice.
Great beginer project or toy for your kid scientist. My kids love it, they want to make couple of them , and they are caling them terminators :) .

For this project you will need:

555 timer
10UF capacitor
47K resistor
100K resistor
cr2032 battery and battery holder ( battery holder can be found on old motherboard)
switch

You can find all the parts in broken electronic devices except 555 timer. You can buy 555 timer on ebay for very cheap 10 pcs for 1 dollar.”
