Here at Voltaic we understand the importance of taking environmental sustainability seriously. Throughout the life cycle of our products we do our best to conserve resources by identifying the best practices...

How to Estimate Solar Charge Time Unfortunately, solar charge time is not as simple as just dividing your battery capacity (measured in Watt hours) by the power of your solar panel (measured in Watts). Even...

The Drifting Buoy Project currently has three buoys drifting in the North Atlantic, Gulf of Mexico and the Pacific. The buoys measure surface location, speed, direction, water temperature and light. The...

We deployed our water quality sensor in a basin near the East River nearly three weeks ago and it is consistently reporting water quality data. Using circuit and software design by Dylan Sri-Jayantha and...

Located in historic Fort Tilden National Park, Camp Rockaway is a 6-week popup campsite created by local architect Kent Johnson. Designed as a way to promote the outdoors as well as the history of Fort Tilden...

In this post, we show how to design a solar-powered water quality monitor using readily available components. The device is designed to float in salt water and send temperature, dissolved oxygen and other...

This post was written by the team at PERCH.LA Ideally, we’d all have solar panels on our homes. The reality is that many of us aren’t homeowners or don’t live in a home that can support a solar array....
