A Perfect Rose, a Stepper, an X-Ray Machine, and Thee

The Day of Compulsory Romance is once more upon us, and in recognition of that fact we submit for your approval an alternative look at one of the symbols of romantic love: an X-ray of a rose.

Normally, diagnostic X-rays are somewhat bland representations of differential densities of the tissues that compose various organs and organ systems, generally rendered in shades of gray. But [Linas K], a physicist with time to kill and access to some cool tools, captured the images in the video below not only in vivid color, but as a movie. The imaging side of the project …read more

Forgot About Valentine’s Day? A Quick IoT Valentine

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 …read more

Valentine’s Heart with Awesome Animations

January has drawn to a close, and for many of you that means: “Oh no! Less than two weeks’ time until Valentine’s day.” But for us here at Hackaday, it means heart-themed blinky projects. Hooray!

[Dmitry Grinberg] has weighed in with his version of the classic heart-shaped LED ring. It’s hard to beat the BOM on this one: just a microcontroller, five resistors, and twenty LEDs. The rest is code, and optionally putting the name of your beloved into the copper layer. Everything is there for you to download.

We’ve featured some epic hacks by [Dmitry] in the past: from …read more

A Heart for His Girlfriend

[Decino] made a nice LED animated blinking heart box for his girlfriend. That’s a nice gesture, but more to the point here, it’s a nice entrée into the world of custom hardware. The project isn’t anything more than a home-etched PCB, a custom 3D-printed case, a mess of LEDs and current-limiting resistors, a shift register, and a microcontroller. (OK, we’re admittedly forgetting the Fifth Element.) The board is even single-sided with pretty wide traces. In short, it’s a great first project that ties together all of the basics without any parts left over. Oh, and did we mention Valentine’s day? …read more
