More Efficient Sprinting with Arduino
Running and sprinting are simple in theory - put one foot in front of the other as fast as possible. It’s not rocket science, but it is a science. This is why learning proper technique is important at any skill level, especially in competitive settings, where even small mistakes can have significant effects. That’s where Sprint Academy Founder Christian Robinson comes in.
Project Requirements
- Simple and fun to use
- Robust

“There are many technologies that provide different metrics but I couldn’t find anything rugged that does it simply,” Robinson said. “I wanted something where I could just drop it wherever I needed and be able to determine that the training I was doing was effective.”
Data over guesswork
As both a caver (a person who explores caves, often referred to as spelunking) for more than 30 years and an ambitious contributor to an open-source map project (OpenStreetMap (OSM)) since 2009, Eric Sibert has a long-standing passion for positional accuracy. In all that time, Sibert has been on a quest to find an accurate and portable tool that allows him to easily switch between these tasks - a quest that has proven to not be so simple.
To meet his requirements, he would need a tool that could be taken into remote caves, but also provide extreme accuracy for correcting street-level data. This dilemma ended up being a drawn-out and fruitless endeavor for quite some time. “I’ve been watching for years for potential GPS chips providing raw data at a low price. I made some attempts in the mid-2000s with the SiRF III chip.

In parallel to the advances in hardware Sibert was seeing, the free and collaborative Centipede Network of reference stations providing real-time corrections was introduced and is quickly growing in France. It reached him at the beginning of 2021. When it arrived, Sibert said, “I added a hc-05 Bluetooth module to my device to get corrections through my smartphone. It is astonishing to have a real-time position with an announced accuracy of a few centimeters.” Then, another breakthrough occurred - “Mid 2021, I got the Sparkfun RTK Express. It is more convenient than my device thanks to its compactness, integrated battery, and configurability.”As both a caver (a person who explores caves, often referred to as spelunking) for more than 30 years and an ambitious contributor to an open-source map project (OpenStreetMap (OSM)) since 2009, Eric Sibert has a long-standing passion for positional accuracy.
