Modding Laser Tag Gear?
digitalsushi writes "With summer here again our thoughts turn to the outdoors, and for two years, my peers and I have tried to find plans online for augmenting our laser tag gear to make it more realistic. We're not engineers, but also figured it can't be that hard to do something with some kind of infrared laser to decrease the beam width. What other sorts of inexpensive things could be added to our gear to make it more interesting? We're using the popular Laser Challenge V2 kits, but any brand at all would be interesting."
Have you ever considered airsoft as an alternative? The guns are expensive but they should still be cheaper then getting realistic laser tag gear and a lot more fun. Airsoft uses air to launch small 6mm plastic BBs and they are designed to look like the real thing. Most guns that are sold in stores like Walmart are very cheaply made and not worth your money. I would recommend getting an AEG (Automatic Electric Gun) from Asia (airsoftshop.com, wgcshop.com) but if you prefer to buy from the US I would recommend combatdepot.com. Airsoft can be dangerous so if you play make sure you are wearing proper eye protection (at least ANSI 87.1). Also be sure to inform any neighbors you have as well as the police that you are having an airsoft game. You do not want the police comming to your house and opening fire on everyone they see.
Well, if it makes you feel any better, when I have kids, I'm going to teach them as much about violence as I can. Extensive martial arts training, stuff like that.
Hey, maybe my kids and your kids can get together and play, and my kids can beat up your kids! Wouldnt that be fun!?
Ok, just kidding. I do fully plan on teaching any/all kids I have as much about self-defense as I possibly can, and that will include extensive training with guns, knives, and "common items" which can be used as weapons in a pinch. I also will be teaching them, from the beginning, the seriousness of what they are learning. There is nothing wrong with letting your kids know how to handle themselves when push comes to shove, just make sure they understand the responsibility that goes with their knowledge.
But maybe that's just me. I always resented my parents for being overly protective in that regard, and not giving me the opportunity to learn how to defend myself - a problem I took upon myself to rectify.
We used to play some lasertag in highschool. My personal favorite hack used a magnifying glass and a poster tube to make a long-range sniper-style rifle.
CONSTRUCTION: basically, i took the IR LED and lens off the old gun. securely insert the proper size magnifying glass lens into one end the the poster tube. Insert a plastic cup that fit inside the other end of tube, but can slide forward and backward in the tube.
ALIGNMENT: using a penlight, stuck through the opening in the plastic cup, determine the focal length of the setup. In a dark room, you can project an image of the lightsource onto a wall by adjusting the distance from the cup to the lens. find the proper locationa and mark it.
FINAL ASSEMBLY: put the LED from the gun into the cup at the end of the tube. remove all excess cardboard of the tube. Firmly attach to the gun. (we used duct tape).Go out and test!
RESULTS: basically this allows you to focus the beam more tightly. the downside is that you have less cross sectional area to the beam. this makes things harder to hit. the upside is that you have a more concentrated beam. this means it travels father. In side-by-side tests with fresh batteries, the modified gun shot fully 3 times further, but you had to be DAMN accurate.
get a good optics book (or even a general physics text) for more on the lens setup.
