LED Magnetic Heart

 

LED Magnetic Heart

Mastelios on Instructables created this LED heart with some earth magnets, 3 Volt Lithium Coin Cell Battery,  a 10 Ohm Resistor and a plastic DVD case.  The heart only lights up when the two halves are connected. Nice touch.

Valentine’s Robo Grinch

Strapped for cash and an upcoming Valentine’s Day date, this user created the Robo Grinch from his spare parts bin. Using some oven knobs, LEDS and other assorted spare parts, Instructable user M.C. Langer ended up with a cute robot for Valentine’s Day.  The LED eyes even light up.

See the Robo Grinch Instructable.

Dark Heart

 

Over at Nerd Kit, they have instructions on how to make this heart with red LEDs.  They want you to buy a kit, but your could probably make this on your own with an Arduino Uno R3 Microcontrollerred LEDS, cardboard and some soldering.
