Meet Evo: the world’s first smartphone-controllable handheld laser. There is a lot of fun to be had with a laser like this. It is open-source, so anyone can create apps for it on iOS or Android. The laser has 4 operating modes: momentary, constant, strobe, and bypass. The Evo is lockable (has a cipher-locked SmartSwitch technology and removable key).
The Evo is made from brushed and hard anodized aircraft-grade aluminum. It is powered by 2 * AA batteries. Sets you back $199.95 at the time of this writing. Just know what you are doing before picking up an Evo.[via]
