Electronic Hourglass DIY Kit
Note, this kit needs to be assembled. You will need a soldering iron and solder – have a look at this soldering iron, it works great for projects like this one.
Using light-emitting diodes instead of sand, this project simulates the movement of an hourglass. Works like a real hourglass, the upper part of the sand (light emitting diode) goes down one by one, the lower part of sand piled up one by one. After the drain is completed, click the switch to restart your hourglass.
The jog switch can adjust the hourglass speed, max. 28 LEDs lit at the same time
Can be used as a decorative night light, power consumption less than 0.5W, is very environmental protection and energy saving.
