Valentines day is just over a month away and you might need that long if you want to really impress that fellow geek in your life with a home made flashing LED Love Heart.

The kit comes with full instructions,a circuit board, 28 LEDs and various diodes and resistors. You’ll need your own soldering iron, battery and plasters (if you’re not that adept at soldering).

As unique presents go it is certainly that, unique. Tacky yes but hey who wouldn’t be impressed if given a home made electronic gift, it certainly beats those singing and flashing cards.

For only $8.99 this is what you get in the box:

Available from (you guessed it) ThinkGeek.
