[iskor12] put together a blu-ray laser that is waterproof and packs quite a punch. At 182 mW there is enough power here to pop dark colored balloons (see the video after the break). To make this happen, he found an LED flashlight that has rubber o-rings for waterproofing. Although small, there is enough space in the case to house the battery, driver, and laser diode. A thick ring of aluminum is placed around the laser diode to act as heat sink.

We’ll admit, we don’t know that much about lasers. This is probably the wrong question to ask, but now that he has this what do you do with it? Leave us a comment about your plans for this diabolical creation.

[Ben Heck] has put the final touches on his Pelican case Xbox 360. This prototype was constructed for use by troops stationed overseas. When he announced the project in October, he already knew some of the hurdles he would face. An industrial Velcro style product is used for all component mounting so the air/water-tight seal of the case remains intact. He sanded the surface so that it would stick better. [Ben] mentions that he ended up using less Velcro than he planned on because it held so well. Not being able to cut the case meant the DVD drive had to be converted to top-loading. The tray movement limit switches have been relocated so they now respond to lid position. He regrets not being able to motorize the lid, but let it go since this is still just the first attempt. Extra copper was added to all of the heat sinks to improve cooling. This Xbox is for sale and he’d love to hear from anyone that wants to put it into production. The write-up has a ton of pictures and you can see a video of it below.
