It’s one thing to see science-fiction slowly become reality, but quite another to take that process into your own hands. Inspired by a movie prop, [Eric Strebel] decided to build himself a 21st science-fiction artifact: a pulsing, life-force amulet.
At the — aheam — heart of this amulet is a blinking LED circuit which [Strebel] modified into a slow pulse with the help of his friends. To add to the surreal quality of the amulet, he sourced a stone from a local gem show, bringing his circuit along to get an idea of what the final product would look like. Once [Strebel] had shaped the stone to a more manageable size, he took a polyester filler mold of its rear face to use as a base from which to cast a durable resin housing for the circuit.
[Strebel] is using a pair of coin cell batteries which fit snugly behind the glowing LED, and in case he ever needs to get inside the amulet, he’s attached the stone to the rear with sew-on straps — super-gluing them to each piece. He went for a bit of an industrial look for the necklace — a braided oil line with a modified quick-release clasp that works like a charm.
How does this amulet stack up to one from the 23rd century? You be the judge!
If Star Trek taught us anything, it’s clearly that we’re not quite in the future yet. Case in point: androids are not supposed to be little flecks of printed circuits with wires and jacks sprouting off them. Androids are supposed to be gorgeous fembots in polyester kimonos with beehive hairdos, designed to do our bidding and controlled by flashing, beeping, serial number necklaces.
Not willing to wait till the 23rd century for this glorious day, [Peter Walsh] designed and built his own android amulet prop from the original series episode “I, Mudd.” There’s a clip below if you need a refresher on this particularly notable 1967 episode, but the gist is that the Enterprise crew is kidnapped by advanced yet simple-minded androids that can be defeated by liberal doses of illogic and overacting.
The androids’ amulets indicate when they BSOD by flashing and beeping. [Peter]’s amulet is a faithful reproduction done up in laser-cut acrylic with LEDs and a driver from a headphone. The leads for the amulet go to a small control box with a battery pack and the disappointing kind of Android, and a palmed microswitch allows you to indicate your current state of confusion.
You’ll be sure to be the hit of any con with this one, although how to make smoke come out of your head is left as an exercise for the reader. Or if you’d prefer a more sophisticated wearable from The Next Generation, check out this polished and professional communicator badge. Both the amulet and the communicator were entries in the Hackaday Sci-Fi contest.

Are you tired of being ignored? Do you want a fashion accessory that says, “Pay attention to me!” If so, you should check out [Al’s] recent instructable. He’s built himself a necklace that includes a display made up of 512 individual LEDs.
This project was built from mostly off-the-shelf components, making it an easy beginner project. The LED display is actually a product that you can purchase for just $25. It includes 512 LEDs aligned in a 16 x 32 grid. The module is easily controlled with a Pixel maker’s kit. This board comes with built-in functionality to control one of these LED modules and can accept input from a variety of sources including Android or PC. The unit is powered from a 2000 mAH LiPo battery.
[Al] had to re-flash the firmware of the Pixel to set it to a low power mode. This mode allows him to get about seven hours of battery life with the 2000 mAH battery. Once the hardware was tested and confirmed to work correctly, [Al] had to pretty things up a bit. Some metallic gold spray paint and rhinestones transformed the project’s cyberpunk look into something you might see in a hip hop video, or at least maybe a Weird Al hip hop video.
The Pixel comes with several Android apps to control the display via Bluetooth. [Al] can choose one of several modes. The first mode allows for pushing animated gif’s to the display. Another will allow the user to specify text to scroll on the display. The user can even specify the text using voice recognition. The final mode allows the user to specify a twitter search string. The phone will push any new tweets matching the terms to the display as scrolling text.
