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).

For more detailed information, see manual in the "Files" tab.

LED Lighthouse Solder Practice Kit

This simple flashing LED circuit is great for learning how to solder or to polish up on your soldering skills. It uses a 555 timer in the astable configuration to flash the LEDs continuously. The rate of flashing can be changed by adjusting the variable trimmer potentiometer R2 (f ≈ 0.3Hz-30Hz). It can be powered by a 9V PP3 battery (not supplied).

The kit is supplied with Yellow LEDs by default but you can choose Red, Blue, Green or White LEDs from the drop-down list above.
