Did you forget about Valentine’s Day? Do you need a quick project to get ready for Valentine’s Day? [Becky Stern] has you covered. She’s whipped up a neat Internet-enabled Valentine project which should be pretty quick to put together.

At its heart (pun intended) is an ESP8266 microcontroller, in this case an Adafruit Feather Huzzah. Several layers of tissue paper heart are stitched together and cut out into a heart shape and then attached to a spring. A vibrating pager motor is used to shake the it when a signal comes in. Two buttons are used to send the message and a red LED is used to light the heart up. The whole thing is enclosed in a shadow box. [Becky] also put together another controller with a similar setup in a plastic enclosure. When the buttons are pressed on either controller, the other gets a signal and the heart shakes and lights up.

These projects send and receive Valentines, but they could be programmed to send whatever information you’d like. If you’re looking for a quick Valentine’s Day project, this is a great one, and you might have all you need already in your component drawer. Break out the soldering iron and send your Valentine a message! If you’re still looking for a quick Valentine’s Day project, check out this animated heart or this PCB Valentine.

Binary Love Clock

binary love clockI combined a strip of WS2812B addressable RGB LEDs with an Arduino, a real-time clock and a beautiful heart-shaped boutique paper box to make an ornament for my wonderful Valentine. It displays the time, in seconds, in binary, since we met… (of course, it’s slightly approximate — I forget the precise second we met, but I think I know to within about 30 minutes!)

Heart-shaped project takes no shortcuts

If all [Blake] wanted to do is scroll “Blake loves Kim” on some LEDs he could have stopped with the breadboard version of the project. Or hastily craft a cardboard heart around the marquee. But he really just used this heart-shaped electronics project as an excuse to get his feet wet with several different types of manufacturing.

The project started as a simple scrolling message pendant. Something along these lines. His very small LED module was being driven by an ATtiny85. He planned to run it from battery which is a perfect excuse to learn how to use the sleep functions built into the chip.

The initial design worked so well he decided to lay out his own circuit board. This made it quite simple to add in a side-positioned button to wake from sleep, and a coin cell battery holder on the back. He used OSH Park for board manufacturing — good thing they allow creative board outlines. To protect the circuitry he also ordered laser-cut acrylic plates that work in conjunction with stand offs to form a case.

He mentions he missed his Valentine’s Day delivery date by a long shot. But that’s how these sort of things go, right?
