Valentine’s Day is right around the corner (already? Wasn’t it just Christmas?!) — if you have a partner or perhaps a cute hacker at your local hackerspace has caught your eye, let them know your circuits are energized by their presence with these adorable Circuit Candy Hearts!

Each one is a small circuit that requires assembly. They come with a CR2032 and a keychain ring for display. But there’s no reason you couldn’t turn it into a necklace or bracelet! With five different designs to choose from, you’ll be able to find the perfect one for your nerdy love. Or, maybe you’re feeling a bit spiteful this year; Alpenglow still has you covered with their PS I Hate You design (which you could also use if you’re feeling particularly tsundere). You can also buy all five designs at once if you have a polyamorous relationship or you just want to brighten the day of your family/close friends!

So whether you’re feeling warm or cold on the 14th, let your feelings be known with these excellent, adorable candy circuit hearts! With Valentine’s day only two weeks away, be sure to order soon so they show up in time.
