Black & Gold Sprints @ Gooski’s

So, what are Black & Gold Sprints? Good question! This is from the website–

Black and Goldsprints are powered by any-old laptop and a relatively simple and inexpensive hardware and software setup developed by The basics; each bike has one roller with a magnet mounted to it and a Hall effect sensor sends a tick to the open-source software each time the roller goes around. An Arduino USB controller does the in between work to make the sensor communicate with the computer. With some simple math one can work backwards from the desired race distance to a number of “ticks”; the sofware thus measures how long it takes for each racer to accumulate X amount of ticks and shows a real-time progress display.

There’s a lot of information on the site. Definitely worth checking into!@ Black & Gold Sprints is coming to Polish Hill —
