Each pair of Glow Rockets starts as a complex PCB design and ends with meticulous hand-assembly.

I am so excited to announce I’ll be vending my latest LED Wearables at THE BOX SHOP’S OPEN HOUSE + MARKET next Sunday!
Come see the future of wearable tech—I’m bringing the brand new battery-free supercapacitor earrings and pendants: the Duonacci, Amoracci, and Fibonacci lines! See for yourself how they glow for up to 16 hours on a 5-minute charge.
Im also bringing tons of my festive Wreath earrings and
selling off the remaining stock of my original battery-powered Spiral earrings!
This is your chance to shop for unique, high-tech gifts.

I often get questions what LEDs I use. Specifically, why I use discrete LEDs instead of addressable ones.
You know those cool, flashy LED strips that can do rainbows and chase patterns? Those use addressable LEDs (like WS2812s). They’re easy, but they consume constant background power and don’t allow for the fine-tuned efficiency I need. This design has about 100 LEDs, and the addressable equivalent LEDs could use up to 50mA+ just sitting in idle. Running these LEDs directly reduced the power consumption to only 1mA while running, and down to 100uA in idle.

Before I switched to supercapacitors, I created these battery-powered LED Wreath Earrings. They’re a classic favorite that combines festive cheer with a touch of tech.
