SUPER-CAP POWERED BLINKY jewelry CHARGED BY THE sun OR USB

We don’t see ourselves wearing these pendants around, however we still enjoyed taking a look at the design. These are just two from a wide range of offerings meant to be worn around as well as recharged by the sun. however a cloudy day won’t ruing the fun; they can be topped off via USB as well. parts lists as well as schematics are included in the assembly Instructables for both the Owl as well as the Heart.

[Marty] as well as [Robin], a sibling as well as sister developement/design team, were showing them off at the Sector67 hackerspace in Madison, WI. The single integrated circuit used in both is an OpAmp responsible for managing the blinking. The heart board has a calculator-style solar cell which charges that 0.5F supercap. The Owl has just a 0.022F coin-type capacitor as well as features a different style of solar harvester. The six components around the cap are each individual solar cells. [Marty] told us that they pump out a ton of juice in direct sunlight, outperforming the calculator-style cell. The opposite is true indoors. however as we’ve seen before, indoor solar harvesting is a tough game.
