Accelerometer Equipped LED Braking Lights Work Even With Engine Brake

vololights-1

Without brake lights, motor vehicles would be pretty dangerous; simply watching that hunk of metal in front of you getting bigger isn’t going to cut it, ever. But standard lights are also not 100% perfect. For instance when you slow down through either engine brake or downshifting, nothing lights up. And there’s rarely a way to tell whether you’ve just tapped the brakes or are mashing them with all your might. The VoloLights solve both those issues by including a 3-axis accelerometer. Sadly for motorcycles only, these LED lights will blink any time you’re slowing down, whether it’s through pressing the brake lever, through downshifting or even engine braking. What’s more, they’ll blink more rapidly in proportion to how fast you’re scrubbing speed. The system is embedded into a license plate holder that also has plate illumination so you can remain street legal. At $79 as a Kickstarter pledge, it’s a pretty affordable way to add yet another layer of safety to your ride.

ShockBox Is A G-Meter For Potential Head Injuries

Playing contact sports is all fun and games (literally) until someone gets a concussion, or worse. It’s not always easy to tell between the player that’s laying on the ground because he got the wind knocked out of him, or the one that needs medical attention because his brain got a shakeup. The ShockBox is a special sensor that is meant to be placed either on or inside a helmet, and it contains two things: an accelerometer and a Bluetooth radio. Should any one player experience a severe hit, a signal is immediately sent to a paired smartphone (say, the coach’s) with impact data and analysis. It uses long range Bluetooth, so the device has a range of up to 100m, and one smartphone can pair with up to 128 sensors at once. This means you could conceivably monitor an entire team, and provide medical assistance when needed. ShockBox installs with 3M double sided tape, which is provided with your $149 unit. Yeah, that’s a lot of money to fork over when you’re decking out an entire high school football team, but if you’ve got the budget, you don’t want to be skimping on safety.
