Even though its a bit late for April Fools jokes, [Ameres] wrote in to share a project guaranteed to catch your friends (or enemies) by surprise.

Instructables user [PenfoldPlant] is a big fan of indoor rock climbing, and while watching others make difficult climbs, he has often wondered if he could follow the same route up the wall.

[Gordon] sent us a tip about this simple laser trip wire system after reading yesterday’s post on a more complicated laser security unit. That build did a lot to provide functionality, such as a system to disarm the trip wire, and a robust light detection circuit.

Instructables user [EngineeringShock] has been hard at work building a laser trip wire security system, complete with a combination lock. The security system works just like you see in the movies, employing an array of mirrors to bounce the laser across an opening several times in order to secure the space.

After reading over the proceedings of the 2005 SIGGRAPH, [Dan] realized he could reproduce one of the projects with $50 worth of equipment and some extreme cleverness.

Have a bunch of time on your hands, and about $2,500 sitting around? Why not settle in and build yourself a laser cutter?
That’s exactly what Buildlog forum member [r691175002] did, and he told us about it in our comments just a few moments ago.

[Joey] likes to dabble in laser projection, building his own hardware and writing the software that drives it. One way that he tests his setup is by replacing the laser assembly with an analog oscilloscope.

This laser display is persistent thanks to a glow-in-the-dark screen. [Daniel] built it using a Blu-ray laser diode. As the laser dot traverses the screen, it charges the phosphors in the glow material, which stay charged long enough to show a full image.

[Rich] over at NothingLabs has put together a really cool laser light show that you really must see in an effort to win a laser cutter from Instructables.

[Pete] had some spare time on his hands over his spring break, and he was itching to build something. He settled on a laser light show since, after all it was spring break, and what says Party better than a laser light show?
He glued three hobby mirrors to three small motors, mounting the motor assemblies on the lid of a wooden cigar box he bought for next to nothing.
