1LT/C – One Laser Tag Per Child
Here it is, just ummm…. 6ish months late for those of you who saw its debut at ‘The Last HOPE’. For everyone else: 1LT/C is a machine that is capable of running L.A.S.E.R. Tag for a cost of about $200, providing you get creative and make your own case out of oh… say cardboard? The end result is still well below $300 after you toss in a cheap keyboard+mouse and house everything in a Pelican case as pictured above.

I’ve built a couple versions of this system based on GRL-UT’s design/advice and found it really fast and cheap for Laser Tag as well as other applications. If you want to upgrade a little the Intel DQ45EK and DG45FC boards can take larger processors. Here is a version (unfortunately w/o the picoPSU):

Utah! Excellent! Greetings from SLC. Do you have a meeting time/place? I’m from SF, and I’m excited to learn of GRL in Utah.
Awesome!
Any advice on getting started further? DIY tutorials or the like? I’m somewhat of a novice, though I’ve built my own electronics before…
Feel free to email directly. Any help is appreciated.
Good work!
Dope — any plans to make available as a kit, or even pre-fab? I’d buy >1
I’m very interested in participating. I’ve got some GRL inspired projects of my own, including games that you play with lasers which I’d love to demo/share.
you forgot to build a clip for the laser pen.
Great! I’d definitely buy it too.. Keep up the good work

I wish I could build something like that, even out of cardboard.
Sorry guys, but this is bull. I love you guys sometimes but you need to get a little less pretentious and add a bit more meat to your posts, rather than just some pretty pictures self back patting. To a 16 year old kid with no background, this page is as good as useless. The result would not be sturdy and could be a fire/ shock hazard. Check hackaday, they always encourage source, tutorials, and build shots for their posts. The stuff you guys do on instructables is a nice step this way. Also, please bear in mind you can get surplus mobos, often with chips, ram, and HD for $25-50 on ebay. Likewise, a used/ surplus gen one netbook would do this and be cheaper and more reliable.
Finally, a $200 cardboard pc does nothing when you guys are using high end projectors with high costs and power requirements. Have you guys ever considered teaming up with lumenlabs? They’re good people, and with a hacked up screen (gen one eeepc for example), this could reach a lot more people.
