We lined the unique Fibonacci Earrings by California STEAM on the weblog, however since then they’ve been tweaked and improved, and at the moment are supercapacitor-based! The all-new Rechargeable Supercapacitor Fibonacci Earrings can be found in turquoise or pink, and identical to the unique are dazzling and a surefire solution to make an entrance at any convention or hacker get-together!
Virtually all wearables with LEDs use coin cell batteries. Whereas these are a neat little bit of expertise, they don’t actually have sufficient oomph to maintain power-hungry circuitry like these LED arrays operating for lengthy evenings. Plus, coin cells have a adverse environmental affect, and the price of operating earrings like these would rapidly get them relegated to the again of the jewellery field. With these points in thoughts, California STEAM determined to check some various technique of vitality storage and got here throughout hybrid supercapacitors which match the invoice completely.
Hybrid supercapacitors have the identical advantages as conventional supercaps — quick cost cycles, low output impedance, and an enormous variety of cost/discharge cycles, whereas additionally providing elevated vitality density and the next working voltage. The caps on these earrings can maintain them operating for 20 hours, after which be totally recharged in solely three minutes from an honest USB energy provide! Add in low self-discharge, and it’s simple to maintain these earrings able to go for an evening in town.
One other change was to 0603 LEDs, which allowed extra colors just like the turquoise and pink we see right here. The older design used 0402 LEDs which have been restricted to extra fundamental colors. If you wish to see them in motion, take a look at the video under, and remember to take a look at the product web page!
