Looking for a simple soldering kit to build for fun, or to help teach someone electrical engineering and soldering skills?

This is a perfect kit for that. Once built, it has 22 Red LEDs that slowly throb. It creates a very cool effect. You can adjust the throb rate with the included potentiometer.

Get if for a friend you like. Gift it on Valentines Day. Or assemble it and give it to someone. Make a tree ornament out of them!

This makes a GREAT Christmas gift, or birthday gift too!

This is a very easy kit to assemble.

It runs on 5V DC. We used a USB cable (not included) to power the one we built.

You can also get a battery box to run it. Its also acceptable to run this on two CR2032 batteries (not included), especially using this battery box.

Quantity per pack: 1 kit
