There are a lot of instructions on the net covering the steps to build yourself a laser, from the large scale models at Power Labs which are not portable to smaller scale ones using DVD/Blu-ray lasers which can't be used for much more than driving the family pet insane. Over at Hack a Day is a detailed project on how to build your own hand held pulse laser which can certainly burn holes through thin metals and other unsuspecting inanimate objects. This particular build is powered by scrounged capacitors from disposable cameras and as long as you keep an even number and ensure the capacitors are all the same rating you can make it even more powerful.
"Self-declared Mad Scientist and Instructables user [Trevor Nestor] recently built a pulse laser pistol and decided to share his build process, so that you too can build a ray gun at home. The gun is made up of mostly scavenged components, save for the Neodymium:YAG laser head, which he purchased on eBay for about $100. He does say however, that you can score an SSY-1 laser from an old rangefinder, providing you hang out near a stockpile of decommissioned Abrams tanks."

Habley has recently shown off a new small, embedded computer dubbed the SOM-6670E6XX. The new computer is the size of a post-it note; however, it sports an Atom E600 processor running at 1.0Gh as well as an integrated GMA600 graphics core. To be more specific, the motherboard in question measures 70mm x 70mm.
The CPU and GPU blend is able to support two displays and pipe two HD video streams to each. Using Media Player Class Home Cinema 1.5, the computer is able to play both a 1080p MPEG4 trailer of the X-Men First Class film and a HD FLV version of SpiderWic simultaneously. While playing both films, the CPU saw around 93% usage and 210 MB of RAM from the Windows Embedded 2009 operating system. Further, while playing an HD FLV film trailer while also watching an HD YouTube clip, the processor was again pegged at 93% usage; however, in this test the RAM usage was much higher, at 422 MB. The test system used, in addition to the SOM-6670, it consisted of a SOMB-073 Carrier board (which provides the various IO including video and audio output, mouse and keyboard input, and SATA ports), 1GB of on-board RAM, and a 5400RPM laptop form factor (2.5”) 120GB hard drive.
Including the two monitors, at 1280x768 (over HDMI) and 1920x1080 (SDVO) respectively, the system drew 18 watts during usage. You can see the test system of the small HD-capable computer in action in the video below. What uses do you have in mind for a micro-sized computer such as this?

If you can't wait for someone to release a mobile PC with the Chromium OS preinstalled, then why not pick up your own laptop and install Chromium yourself? ExtremeTech walks you through the process, from finding or making a build to install and installing it on a bootable USB device to moving that installation onto an internal drive. There are links to troubleshooting sites and they reveal that the default password seems to be facepunch.
"On June 15, Samsung and Acer will release the first consumer-oriented Chrome OS laptops, or Chromebooks as Google likes to call them. Both hardware- and software-wise, these netbooks are nothing special: You can download Chrome OS's open source brother, Chromium OS, for free -- and at around $400 for a Chromebook, you would certainly expect some better hardware than what Samsung and Acer are offering.
In fact, for around $300 you can get a cheaper and more powerful netbook with Windows 7 pre-installed -- and it only takes about 30 minutes to wipe Windows and install Chrome OS yourself. You'll end up with a better and cheaper Chromebook -- and to top it off, you'll have a spare Windows 7 license that you can give to your mom."

Wired offers you several ways to build your own laser, some powerful enough to burn holes in paper and other flammables but all able to ruin the eyesight of anyone you point it at ... so bear that in mind. They range from a build claiming you need no soldering for those less technical people who want a laser to one built in an Altoids tin. The power of the laser varies depending on the build, some even use re-purposed DVD lasers as the light source. Perhaps the most impressive build lacks wattage but being able to project vector graphics with lasers more than makes up for it.
"Even though lasers are as common as dirt now, appearing in everything from DVD players to supermarket scanners to computer mice, there's still a certain appeal to a beam of coherent, monochromatic light. Especially if it's dangerously powerful.
So it's no surprise that people can't resist playing with lasers, building their own, customizing them and, of course, setting stuff on fire with them."
