Biking can be dangerous. Drivers don’t know when you are going to hit the brakes or make a sudden turn. It would be much safer if you had a brake light. The Spooklight has a wireless handlebar touchpad and an accelerometer that lights up your brake light when you slow down.

Just like how a car works. The LEDs are super bright, and the lithium polymer battery will keep it working for about 60 hours. The Spooklight easily comes off the bike and charges via USB. And yes it will also charge your gadgets while you’re on the go.

This little device will sit on your wrist and actually sense your happiness levels through your skin and let you know just how happy you are. It has an accelerator that senses your movement when you work or do other activities. A GSR lead is attached to your fingers and detects galvanic skin response so it can judge how tense or how happy you are. A voice sensor will also detect repetitive phrases when you say them. The sensors work with Bluetooth technology.

The result is that Robometer displays various colors and a voice prompt to remind you about the things that make you happy. I can only assume that some of us for whatever reason, don’t actually know when we’re happy. For those dim-witted souls, this device will bring a smile.
