Let your geek shine. Meet Landon Cox, proud father, SparkFun customer, and developer of a novel timing system for speed climbers that is both precise and easier on climbers’ hands. Using laser switches, hand-built enclosures, and plenty of brutal tests by his speed climber daughter, Landon debuted his timing system at the USAC Nationals earlier this year. Whether you’re searching for a breakout board, or prototyping a climbing sensor to withstand high-impact abuse, the tools are out there. Create a project you’ll love, and let your geek shine too.
