We’ve covered [mitxela] in the past and if you know him, you’ll likely know him for putting the micro in microelectronics. This year, he’s at it again with his LED Industrial Piercing.
Inspired by the absolutely tiny 0402 LEDs and industrial piercings, [mitxela] started thinking of a way to construct the 5cm long device. He found some normal LED earrings to steal the battery compartment from. Then, with a tick needle and some more steel, he created a new industrial earring with some holes.
Of course, no [mitxela] project is complete without comically tiny microsoldering and this project makes the VQFN ATTiny he used look large. He puts his PCB suppliers to the test with a merely 1mm wide flex PCB for the LEDs to be mounted on. Finally, he combines the flex PCB, the earring and some epoxy to create yet another piece of LED jewelry.

Well, at least now us ticks can see to bite you better because of the bright lights. Thanks [mitxela]! What’s that you say… “do ticks have eyes”? Of course we do, see Tick Anatomy 101 [1] below.

“On the Internet, no one knows if you’re a dog!”
Your comment gives me mixed feelings, I have previously only had contempt for ticks. But the insightful comments you have made previously on Hackaday, forces me to widen my perspective.
I think [Kristina Panos] would be interested in the keyboard you use.
Beyond the showy aspect, what sensor applications could be realized? Starting with pulse oximetry you’ll likely not lose during workouts, to biochemical measurements?
This would take my Prince Albert to the next level.
Underpants Disco! Whop! Whop!
I would love to know who the PCB manufacturers are that were able to make that. I may have some projects that would likely be as extreme. I had not seen anyone that could make something that small in flex.
That pcb is a very simple one called a flex pcb you just say it is flex when you order it… They are a bit more expensive than ridgid pcbs and of course you can do even more complex with ridgid flex
Is it possible to change the weak laptopscreen leds with something more powerful? Any links?
