A man builds a real life phaser seen from Star Trek. Fun stuffz :
Hmm a modified laser pointer ?
Nice invention. Now we need to find a lot more frequencies in case the Borg decide to stop by ....
The guys burning his basement all for the love of being a trekie?
I want one. :nerd:
Did he build it to stop Shatner from releasing another album?
thats actually really cool. oh man
That's funny. It probably wouldn't be legal for him to take it out in public, though. If it's strong enough to pop a balloon then it would definitely harm someone's eye. Eventually batteries will be powerful enough for small lasers like that to put out some serious damage.
you know you can take green laser pointers out in public, and those burn retinas easily. people use them to point out stars in the night sky.
one guy i know modified an already strong green laser pointer, i forget how exactly. it burned paper and clothing.
At least his phaser has a safety button.
Star trek phaser..Meh.
Build a lightsaber and ill be very impressed.
This has been around for ages. They use a Blu-ray or HD-DVD drive laser.
That's great, I'd buy one of those. Someone needs to release the TOS communicator as a phone.
What's the maximum rating for a blue ray or DVD burner laser? I can't imagine something that small could handle very much power.
I have a broken CD player I never threw away, yet. Can this type of laser do something or would it just be a light until it breaks?
well blu ray burners (which are violet lasers) can put out 5-800mw depending on their burn speed, so ive heard. thats pretty powerful. enough to burn things easily! dvd burners and players use red lasers. i dont think output enough mw to do anything except blind somebody.
yeah the first guy to post videos about this used a ps3! that only puts out about 30-40mw so not enough to pop balloons or anything fun
Well, I just did a little research on lasers. I could buy a laser pointer with 1W of output, but it's $138 and overkill. In fact, the quality high-powered laser pointers are all relatively expensive compared to the <5mW pointers.
I have a laptop here who's motherboard died. I just pulled out the DVD burner and it says it's a class 3B laser. I could eventually make my own laser device, although I may need something called a laser driver. It would still be cheaper and more fun to improvise my own some day instead of buying one of the expensive ones. I already know about circuits and how to solder. I'd still have to do a lot more research on how to remove and reinstall this laser properly since it's so small.
Let KipKay show you the way
Well, I took it apart and these certainly are not typical laser diodes. Panasonic calls them hologram units, which seem to be more complicated. They have the data sheet for the CD burner hologram unit, but there isn't one for the DVD burner hologram unit. I'll have to find one elsewhere to experiment with lasers. Just my luck.
