Star Trek submarine

You can try to be unimpressed. You can attempt to feign disinterest. But even the most casual Star Trek fan will get giddy watching this model submarine in action.  Apparently there is a group that builds under water R/C vehicles from static models. It’s not Star Trek exclusively either, we saw some anime vehicles as well as a modern-day shuttle replica.

Set phasers to “blind”


[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.

LED Enterprise


[Wolf] built this LED Enterprise model. It’s a ‘sparebot‘ assembled from leftover LEDs and resistors. Unlike most sparebot sculptural oddities, this one actually works. If you place it near a magnet, a reed switch closes to turn on the LEDs. A mechanical switch would have just caused more stress on the model. The part count is very low, but took some forethought. Two resistors are used to raise the resistance of the red LEDs to match the white LED. A quite clever and simple model.
