Collaborate Disseminate
Inspired by many months of hours-long load shedding in South Africa, [JGJMatt] decided to make a portable speaker that can play tunes for hours on a single charge and even …read more Continue reading Building a Solar-Powered, Supercapacitor-Based Speaker
Supercapacitors are definitely not the same as batteries, we all know that. They tend to have a very low operating voltage, and due to their operating principle of storing charge …read more Continue reading SuperCapacitors vs Batteries Again
Without knowing it, we’ve spent years watching [Jasper Sikken] piece together an empire of energy harvesting equipment, and now he’s putting the pieces together into wonderful creations. His recently finished …read more Continue reading Magic Pyramids Blink Eternal with the Power of the Sun
One of the biggest challenges for wireless sensor networks is that of power. Solar panels usually produce less power than you hoped, especially small ones, and designing super low power circuits is tricky. [Strange.rand] has dropped into the low-power rabbit hole, and is designing a low-cost wireless sensor node that …read more

We’ve all committed the sin of making a little arduino robot and running it off AA batteries. Little Flash is better than that and runs off three 350 F capacitors.
In fact, that’s the entire mission of the robot. [Mike Rigsby] wants people to know there’s a better way. What’s …read more
