Many a maker likes to use their craft to create gifts for loved ones. [Jiří Praus] was celebrating having been married for 5 years, and crafted this beautiful LED heart sculpture to commemorate the occasion.
The outer shell was created by first starting with a 3D printed heart shape. This was used as a form upon which the brass wire could be soldered together to form an attractive heart-shaped cage. Inside, an Arduino Nano is hooked up to a series of WS2812b LEDs. The LEDs are flashed in time with the heartbeat of the person holding the heart, thanks to a MAX30102 heartbeat sensor. There’s also a TP4056 charge module and a small lithium battery to provide power for the device.
Adding the heartbeat sensor really makes this project shine, forming a connection between the holder and the device itself. The tasteful craftsmanship of the brass design makes this an excellent gift, one we’re sure anyone would like to receive. We’ve seen [Jiří Praus] make the most of this artform before too, with projects like this stunning tulip or dead-bug Arduino. Video after the break.
“heart-shaped cage”. Sounds like most every relationship I’ve ever been in.
+1 lol
Hmmmm if it’s every relationship then maybe the problem is you? Sorry buddy, been there too. Best of luck working it out. Glad I eventually did, it was well worth it.
Dang, that is one good-looking soldered brass wire cage. That’s tough to do that cleanly, came out looking great.
Can this get a bit freaky for the wearer? I have a pulse meter and there’s a “feedback” aspect to it, that can make your pulse race….
Lovely idea. Pretty sure my girl would love getting a present like this too.
The only thing that bothers me a bit is that it’s lacking symmetry and that there is a 4-corner polygon in the center to allow for the pushbutton-activation. I’d probably try to put a little IMU in there and have it activate if you move/pick up the heart…
Man, this is really nice. Kudos to the designer.
Man, I wish this was a product for sale… I’d love to buy one.
Using addressable LEDs seems unnecessary, since after the extraneous startup sequence they all pulse together.
