Hardware Startup

My adventures in electronics and as a second time founder of a hardware/electronics startup

About

I’m a hardware designer, startup founder and father of two kids. I love building and launching products and want to share some of the things that I have learned over the years. My first product is GrowGuard, a way to connect your plants to the Internet. It allows you to record and watch their growing conditions over time and get alarms when things are going bad.

High-speed camera system catches close-ups of snowflakes in mid-air

Ben Coxworth

Falling snow can play havoc with radar systems, so the more that we know about the manner in which snow falls, the better that those systems can be equipped to compensate for it. That’s why for the past three years, researchers from the University of Utah have been developing a device known as the Multi-Angle Snowflake Camera – or MASC. Using three cameras and two motion sensors, it captures 3D photos of snowflakes in free-fall.
