LED Jack-o'-lantern Solder Practice Kit and Halloween Decoration

Practice your soldering in style with this simple flashing LED circuit. It uses a CD4017 decade counter IC to flash the LEDs sequentially. The rate of flashing and brightness can be adjusted via two potentiometers, which also act as a stand for the jack-o'-lantern. It can be powered by a 9V PP3 battery or a 6 x AA battery holder (not supplied).
