Hands-on with GlassLight for Google Glass

Adafruit's first electronic accessory for Google Glass is here, and it's a voice controlled flashlight you can mount to the MicroUSB port.

We learned a while back that the MicroUSB port on Google Glass was going to be used for more than connecting to your PC and charging the device when the mono bug and stereo earbuds were released by Google. While it's a huge deal to have these audio enhancing accessories around, especially if you're the type to wander around the house and listen to music through Glass, there's still plenty more that can be done with this little port. Enter the GlassLight, a simple flashlight add-on for Google Glass that can be voice activated.

This accessory is just about as simple as it gets. GlassLight snaps into the MicroUSB port and sits dormant until you tell it to do something. In order to have a command to issue to the accessory, you have to side-load the APK from Adafruit. Once installed you gain a simple "Toggle Flashlight" command that turns the light on and off. Since all you are doing is activating a single tiny LED back by your ear, both the battery drain and the amount of light produced are extremely minimal. In its current form you won't be using this to go for a late night stroll in the woods, but if you're elbows deep in a computer trying to replace a motherboard the added light right where your eyes are pointed is a great tool to have.

For $30 you get a decent starting point that isn't likely to be a part of your regular Glass setup out of the box, but is still a cool accessory to have in your Glass arsenal. This being an Adafruit project, you have everything you need to make any adjustments you see fit. Replacing the onboard LED with something a little brighter, or even just adding some kind of focusing lens to control the distribution of light are examples of things you have the ability to do to improve this concept and make it your own.



I would love to be able to test this...just need to get my hands on Google Glass.


I hope they make a video to show it in action. It's pretty cool to see the new ideas people come up with to make tech even more useful.


£1500 for a device that prides itself as there to catch every moment, I'd seriously be miffed to find out there's no flash to be honest....


I love the idea of Google Glass, but three things suck about it: 1. The price 2.It's made by Google, and I really don't like Google (as a company) 3.You can only attach one accesory to it at a time

I never knew you could add attachments to google glass. The possibilities are endless.

I wouldn't mind having a Google glass but they are quite expensive and don't look very cool.


Sounds like a nice addition!


pretty cool, although its weird that Google didn't think to add a 3 dollar light to a $1500 product.
