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!
