Does anyone have or know a cheap source of IR lasers. Also can one be made form a green laser? I want to build one for long range night vision viewing. Thanks!

to control fan speed,(computer fan) is it done by resistance or by voltage

Re: 4.5v Laser can it be powered with 5V and a Res all went well :) I now have a wall plug powered diode, with adjustable brightness :D

Re: 4.5v Laser can it be powered with 5V and a Res when you say pot, you mean the dial on the variable resistor? i got a fairly high one so should be good :) I havent done a tun of electronic stuff in a while, so just starting to get play with it all again :)

"should" you have an IR filter for any greeny?

Re: 4.5v Laser can it be powered with 5V and a Res Well i have a crap keychain one i want to use to make my motor/mirror contraptoion for now, i just want to be able to playg it in, so i dont go through to manny battereis, will do the job for testing.. would that work thoe.. it takes 4.5v the...

Do you have the schematic for it? I would like to attempt to build one! :D is it powered of batteries or ac>dc plug?

I was looking at the box one, i dont see how the straight cable would work thoe

Before i try it, a laser that normally takes 4.5v (3 1.5v little batteries) can i power it with a 9v wall charger if i use a 5v regulator and run it through a variable resistor? Just want to check before i potential burn it out.... :D

haha that is a little tripod :P

Is there general dual laser ones or do you need custom ones.. better to just get lower power ones or get higher and goggles! :P

Wow , glasses cost more than the lasers! Is there goggles that do both red and green

Ok so i orderd 100 UV leds, iknow they arnt 100% acual UV but they still make things glow like a black light atleast thats the plan.. a Big CIS style light is defintly on the list.. not quite sure what else to make yet.. I may buy a couple single laser modules to play with.. either 30 or 50mw...

how much would you want for a controller board? I like how it has the random/auto function!

Looks more like a projector IMO

ok now you guys have done it, i have to build one,.. one color or two.. how many MW laser do you generally use for them? I might make one with either R/G or both :) Do PC fans spin fast enough? or is the something more preferable for a motor? One lase Q, for working with laser i know you...

Sweet pics! im going to have to work on building one of those

I use fog or haze, use a tripod, set a timer, for 2 second delay before it takes the camera, (you pushing the shutter button will shake it. and turn off the flash.. I have got amazing pics by doing this :)

lol, everyone is obsessed with burning stuff! Personally i love the light shows from scanners, it what sold me... I may buy a single green just diode or pointer one of these days to play with thoe.. after seeing what you guys do with them, could be new toys to play with.. I just bought a...

awesome, thanks for your help :)
