With some basic LED’s you too can create your very own LED DIGITAL CLOCK! This is a great little project to practise soldering as well, using the awesome little micro-controller Arduino.
So get stuck in, have fun, and don’t forget you need 130 LED’s

Make your own digital clock
Turn a glue stick into a flashlight!
First pioneered in 2005 and only posted till just recently, we present the glue stick flashlight!
This neat little flashlight is housed inside the glue stick, powered by one AA battery. Using two white LED’s to provide the light, the only issue is it needs 7.2volts to run the LED’s. No problem! with his custom step-up converter using a transistor, inductor and other components. I like it!
