If ever there was a quintessential weapon of science fiction, it would have to be the ray gun. [lonesoulsurfer] built this one-of-a-kind stunner from his impressive collection of junk. It’s centered around a vintage Bakelite soldering gun, a vacuum tube, and a portable stove burner, all of which contribute to the fantastic mid-century look.
Inside is a slightly modified version of a ray gun sound effects circuit from MAKE: that squeezes square waves from a lo-fi synth builder’s favorite IC, the 40106 hex inverting Schmitt trigger. [lonesoulsurfer] was able to reuse the soldering gun’s trigger to start the pew-pew-pew, and he can adjust the death ray’s output with potentiometers. The gun is powered by an old cell phone battery and a combo Li-ion charger/step-up module from the world’s largest virtual auction house. Blast past the break to watch the build video.
If one little green LED isn’t enough for you, maybe you’d prefer this light painting gun.

Faced with a printer that would stop printing for no apparent reason, Finnish pirate and hacker [Janne] decided he had had enough. After doing a bit of research, he disassembled the drum assembly and replaced some components. The end result? Supposedly ‘broken’ printers started working again.

Here’s another Star Trek phaser toy with a laser added. [Jay] started with a 1994 Star Trek phaser and added a 12X Blu-Ray diode. The sound effects of the toy still work, a nice touch that you can check out in the video after the break. That video shows him popping balloons with the laser, a feat made possible by the 465 mW that it puts out when the diode is driven at 320 mA of current. He’s made a nice carrying case for the weapon but we didn’t see a spot in there for protective glasses like we’ve seen with other phaser hacks. He did make one safety consideration by adding a safety switch and indicator LED to signal when the laser diode is armed.

[Directive0] added a 200mW laser to his Enterprise Phase Pistol toy. This joins the ranks of hand-held laser hacks that we’ve seen around here lately. His build makes use of the stun and kill settings of the toy to switch between different modes. The built-in 9 volt battery holder is tapped into for power. When set to stun, the stun LED indicator is illuminated and a trigger pull sends current limited electricity to the laser diode. When the kill (or blind) setting is selected, the appropriate LED is illuminated and the trigger sends the full current from the battery to the laser diode. Power regulation is managed by the driver circuit for the laser.
This build preserves the unmodded look of the toy gun. [Directive0’s] inclusion of protective glass should fend off the warnings we usually see in the comments of these types of hacks.
Phasers come with two settings: stun and kill. [Luke] took this seriously when he put two 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.
