The face of the clock consists of individual wavers of solar panel glued into a huge clock-like array. The solar cells feed into an Adafruit PowerBoost 500, a TPL5111 low power timer breakout, and ...

This solar clock was built using a lot of salvaged parts. We find it interesting that [Nereus] combined a ring of storage capacitors with a power cell (translated) to create a hybrid energy storage… ...

A new solar clock could monitor the rhythm of the sun's magnetic field and help predict solar flare surges that can damage communication systems on Earth. Skip to main content.

By John Strege The pace of play is a perpetual issue for which any number of solutions have been proffered (see the USGA's "while we're young" campaign). Here's a new one: Solar-powered clocks.

At 10:00 GMT on Monday, the most important alarm clock in the Solar System will wake up ESA's sleeping Rosetta spacecraft. Rosetta is chasing comet 67P/Churyumov–Gerasimenko and, since its ...
