Less than two weeks away, it is time to make your special someone a present. Below are five DIY projects that involve gluing, soldering, microcontrollers, painting and general making to create gifts for Valentine’s Day.
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.
Wearable Glowing 3D Heart
Using a glue gun, coin cell battery and a really small led, Instructables user circuitbreaker created this red heart. He used the glue gun to slowly build up layers of glue that form the heart. Wearable Glowing 3d Heart
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.
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 Microcontroller, red LEDS, cardboard and some soldering.
Heart Rate Monitor
Using an Arduino Microcontroller and a photodiode Instructable user ohoilett created a heart rate monitor. I’m sure you could dress it up with red cardboard hearts to make it more Valentine’s Day appropriate.
