i ordered a 150mW red with a built in driver from laser lands and i received the next level down model with a larger driver board outside of the module. the thing is im kind of pissed but i can deal with it because im not gunna wait a month and a half just to get the right model with the same...

i was wondering about how its such a big deal shining, pointing, or waving your laser pointer or labby at a plane, heli, or any aircraft. but just how annoying is a laser a few hundred feet away or w/e cruising altitude most planes are at. i mean Ive seen my 50mw green about a hundred feet away...

i was wondering if anyone would be interested in some pre-built laser spirographs or if you would like to assemble them yourself you could do that also i could send it as a kit. i am very interested in your opinions and i see that everyone has a list of lasers in there signatures and wouldnt it...

i was looking into building a red, green, and yellow laser i know i need a turning mirror atleast im pretty sure. i bought a 50mW from laserlands a while back and now i need a red and ive been looking for a review and cant seem to find one for this laser----->Industrial 150mW Red Laser Module...

im very involved with electronics and now im starting to get into lasers and im mostly interested in circuits for them and the various effects and other systems you can buy. i was currently thinking about making and selling a power supply circuit for any laser within the circuits limitations...

i finished my Spirograph and now im onto a new project working with hdd galvos and Ive been getting most of my info around the web and mostly on here. and im starting to build the circuitry to drive my "hdd galvos" this circuit so far is of my own design because i like to be original and develop...

this is a spirograph ive built lately and i hope to make it better soon but i cant play around with it too much because its for an electronics competition. i used 555 timer circuits to pwm the pc fans which worked pretty well. i got my fs mirror out of a rear projection tv. and my 50mW green...

my dads been in construction for a while and he pulled out this laser grader or marker and was showing me. theres a 5mW laser mounted in the head which spins and makes a line across the wall,floor, and ceiling. its used to get straight walls and ceiling tiles and he said 10 or so years ago it...

this is my first spirograph and is what i consider my first working prototype. i plan on making alot of improvements, better speed control circuitry, better variability in speed. im using my 50mw green laser module from laser lands a good module but apparently im cooling it too much and might be...

i got a 50mw 532nm green from laserlands and its awesome but lately ive gotten some weird like spurts of green shooting out at a 45 from the beam :wtf:you usually get. anybody ever get this? i dont get it all the time and to fix it i just turn the laser on and off a couple of times. :thinking:

i recently found out what a phr sled was and that you can get dichro optics out of them and i have a few questions. - are the optics contained in the part that slides on the rails? - do xbox sleds contain good optics? - i really enjoy using ebay anyone got good links to sled sellers? ive looked...
