Avoid Bicycle Crashes With A DIY Distance Warning System

In an effort to make bike riding safer, DIYer Ben Heck builds this proximity sensor for bikes, that warns when you’re getting too close to cars or other objects on the road.

The final product is similar to the sensors in your car that beep when you get too close to something — except Heck’s design works the entire time you’re riding, so that you won’t get hit by any opening doors or bushwhacking ninjas. Check out the video above to see how he puts it all together with an Arduino, some ping sensors, and a few LED lights.
