What’s the perfect gift for the special someone that puts up with a soldering iron in the kitchen and little bits of wire underfoot? How about this touch activated, pulsating LED heart? This geeky Valentine’s Day card pays homage to the musical greeting cards that are popular this time of year. This isn’t just for Valentine’s Day — it’s a simple heart, so give it to your loved one any time of the year. You can also make your own shapes using the same basic circuit. [via]
