In this post, we show you how to build a solar-powered asset tracker for your bicycle or other important equipment using Adafruit FONA 808 and Freeboard. We will show you how to 3D print a custom case, wire...

In this post, I will discuss how we are working to revolutionize bird research by creating a solar powered bird feeder with a range of data collection capabilities. I will focus on how we have worked to...

We sometimes need a lightweight way to track power production of our panels in places that are far from an electrical outlet. In this post, we show you how to design a voltage, current and luminosity data...

Tutorial: Solar Power for Raspberry Pi This post will walk you though how to protect your Raspberry Pi while powering it from a solar-powered system, and provide some tips for reducing the power consumption....

Direct solar charging from a solar panel without any intermediate battery reduces complexity and weight of the system, but there are several challenges to making it work consistently across all phones. We...

Particle Electron Power Consumption How much power does the Particle Electron consume? When designing a solar-powered IoT project, it is always important to have a good real-world sense for how much power...

Hi there folks, In this post, I'm going to talk about building a simple solar powered cloud-connected weather station using the Particle Electron. I'll also discuss the tradeoffs between the different power...

Tutorial: Power Consumption for Time Lapse with Motion Control Complicated time lapse camera moves require a lot of power. Camera batteries, motion controllers, tablets/computers, and motors all require...

Solar Charger Peace Corps Discount Congratulations on your acceptance into the Peace Corps! We are excited for you to start your journey and are happy to extend a Peace Corps discount to help provide power...

LittleBits are a set of small electronic toys that allow kids (and adult engineers like myself) to easily build electrical inventions. There are different types of power, input, and output components that can...

Solar Panel Longevity: 2 Year Update Often our customers ask "How long can the panels stay in the sun before I should take them down?" Sure the technical answer is that the panels can last 8-10 years in the...

We are always excited to learn about new products that equip adventure-seekers in a more sustainable, green way. One of these trends that we've seen grow over the past few years is the emergence of...

Makers and engineers all over the world are using our solar panels to power their DIY microcontroller projects, but until recently no one had designed a printed circuit board and launched a successful...

Chromebooks have become increasingly popular over the last few years and customers have been asking us about how to charge them from solar. Most of them charge similar to laptops, but have the energy...

We recently collaborated with Nicholas Johnson to build  a solar-powered air quality sensor that sends real-time information to the web for anyone to see via the cellular network.  This project shows the...

In cooperation with Nicholas Johnson, we built a dust sensor that operates roughly 24x7 and publishes the results consistently to the web via GSM.  The project combines an inexpensive air quality dust sensor...

DIY: Waterproof Case for Solar Powered Projects This post outlines the steps necessary to build your own waterproof case for solar Arduino (or Raspberry Pi) projects that you want to leave outdoors. We've...

The PIXO charger has been discontinued. We now offer alternative ways to charge both AAs from USB and camera batteries from USB. Ever wanted to charge a DSLR camera battery while off-grid but only had a...
