Whether it’s exploring uncharted caves in France or contributing to an open source street-mapping project, Eric Sibert relies on the SparkFun RTK Express for the positional accuracy he needs.
When Adam Garbo of the Water and Ice Research Laboratory at Carleton University saw a lack of data coming from the cryosphere, he turned to an affordable, open-sourced solution he dubbed the Cryologger.
When Jean Rabault Førland was looking for a cheaper and more compact way to collect data on sea ice for the Norwegian Meteorological Institute, he looked to the Artemis Global Tracker (AGT) as an alternative.
We looked into what farming, ag tech and similar companies were doing with our components, and created a resource page for anyone exploring tech to improve productivity, efficiency, safety, and resource utilization in agriculture.
Starting a brewery led to designing a better automatic keg washer that saves time and money.
To help feed the planet in 2050, this group is trying to find ways to make farming more sustainable.
For many of us, air quality was top of mind this summer. PurpleAir was there to help.
Distance sensing combined with haptic feedback create a way to "see" the world around you.
When it comes to training, athletes need to know whether they're improving - that's where one SparkFun customer's system comes in.
When a GPS module with a small footprint and extreme accuracy is needed, GPS-RTK2 is just the thing.
When faced with the option of buying something to fit his needs or building it himself, Anker Berg-Sonne chose to take the DIY route.
