Laser raygun boasts 300mW, hunts Klingons
Phasers come with two settings: stun and kill. [Luke] took this seriously when he puttwo Blu-ray lasers into a toy raygun. He picked up the toy from Amazon for about twenty bucks and set to work.
The laser diodes are both pulled out of a 6x BD-R burner, which we think is a pretty expensive source to scavenge from. [Luke] removed the toy circuitry, reusing the trigger, top switch, and battery pack. The two diodes are mounted on a swiveling carriage which is turned 180 degrees to switch between the two diodes. A boost driver converts the 3v from the batteries up to 7v for the diodes.
This is a skillful conversion and [Luke] should be proud. Don’t miss the video after the break and if you’re thirsty for more take a look at the last hand held laser we featured.
우홋... 재밌겠다. 방금 스타트랙 더 비기닝보고 와서그런지 더욱더 애착이 가는 작품 ㅎㅎ

Awesome robots love Fanta
What you are seeing above is not a commercial for Fanta, though we think it would have been a good one. It also isn’t being played at an accelerated speed. That is a real time demonstration of the accuracy and speed the ABB robots achieve. We were surprised, even shocked, when we clicked play. We don’t know who came up with this idea, but we want those robots, and we want some Fanta. We’re a bit curious what industry needs beverage tracing robots though.
The last time we saw such amazing feats of robot awesomeness, they were bouncing balls and catching stuff in mid air.
Remotely control your crappy car (dangerously)

Here’s one that brings back that giddy feeling we got when the original episodes of thebroken were posted all those years ago. The lunatics over at Waterloo Labs havealtered a beat-up Oldsmobile for remote control via laptop, iPhone, and…. wait for it…Power Wheels.
Brake and gas pedals are actuated using a wrench connected to a motor bolted to the floorboards of the car. The steering wheel has been replaced with a gear and connected to a motor using a motorcycle chain. Much like the van we saw last month, an iPhone app has been written to wirelessly control the car of doom. This leads to some car surfing and ghost riding the whip in the video after the break.
To our delight, they’ve also implement the most unorthodox automotive interface yet, Power Wheels. A chain has been added to measure the orientation of the toy steering wheel, and an optical encoder is used to measure the speed of the tiny electric vehicle. It looks like it doesn’t do the best job of translating to a full size vehicle, but it maxes out their style points.
Homopolar motor

Slow day at the office? Here’s a trick that’ll make your coworkers smile. Dangerously Fun has a guide to build a homopolar motor from a battery, copper wire, and magnet. A homopolor motor doesn’t rely on electromagnets in an armature changing their polarity to force a rotation movement compared to stationary magnets. Instead, they use an electrical current’s orientation to a magnetic field to provide a repulsive or rotational force. In this implementation, the current moves through a loops of copper wire from one pole of a battery to the other. A rare-earth magnet on one pole of the battery provides the magnetic field.
After the break we’ve embedded video of this simple example as well as a few more complex homopolar examples such as a five speed version. The motor in action certainly brings a smile to our faces and places this firmly in the useless machinesfamily of hacks.
