huh i had no idea it could be problematic at cool temps. ill have to try that out. if i could i would have had liquid nitrogen drippin on it :D i guess ill put a switch on the fan so if it does get to warm ill bring it back down to temp. right now i have it where my cooling fans for the various...

yeah theyre blue/violet is extremely false advertised no hint of blue at all that you see with other diodes

thanks for posting the vid your very helpfull i am seeing some of the "kink" if i understand it right. do you think that my current isnt steady? or that i should make it steadier? how? also isnt the colder the better and longer life? ill see if i can get mine up here by tonight to show you.

yeah slow and reversible sounds nice and i want to start making some with reg dc motors and i know theyre EVERYWHERE im not a tard and take it easy my spiro is pretty complex :cryyy:but not pc driven. and thanks for the info but i kinda already knew it but wasnt sure if alot of people did...

im gunna take pics of my fans running tonight cuz i feel that your a fan hater :na: i also do not like that you cant flip flop polarity cuz most pc fans are brushless and theres a circuit in there controlling it. and i love the fact that pc fans are easily mounted CUZ THERE SQAURE and its easy...

im running it off of a lm317 to supply 2.9 volts when adjusted to the driver already on the diode and the driver has a pot on it. should i lower the current to the driver or trim the pot. and its not a crazy like vibrant 45 beam coming off of it but when it shines on the wall you can see the...

this isnt a detailed video but ive seen others on it and its sortof like a coating that can really pick up light behing objects idk i cant explain it but if you find a better video you might get it. YouTube - Optical Camouflage (Invisible Cloak)

recycling is always best i built half of my spiro with parts from the trash including my fs mirror

is it possible that im cooling it too much? without a heat sink when i bought it at first it would dim after 3 min operating and be warm. with my heat sink i have yet to reach a max operating time. i also have it sitting on top of a fan gettin pretty frosty. i would like to attach a picture but...

i also immediately thought lens issues or defects but i dont see how it can happen periodically. after that i thought maybe power issues im running it off a lm317 circuit. ill have to check with my meter tonight cant right now its over my friends house on my spirograph :yabbem: also takin some...

what Ive found is that as long as you don't have any problems getting from mirror to mirror to the last just adjust the last mirror accordingly and you can get any size and distance you want. me and everybody on here knows that you can glue the mirror down permanently but im trying to figure out...

o wow nice idea with the penny i just got it thats a good idea but i like using pc case fans they look nice although since there brushless pwm is kinda weird.

i cannnnn do that i gots the smarts i cut and and balance mirrors and i think i did pretty good for my first laser spirograph that i made recently. hopefully soon ill be getting a few more rptv's then ill have a shit load of nice optics and fs mirror.

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:

wow im stupid what i meant to say is that theyre 50mw green was awesome and the violet is not that cool besides me needing for an rgv soon

i like laserlands also and bought there 50mw which amazed me but it think the 50 is lacking i havent tried it out in smoke yet and im not that interested in burning but im gunna order a red and maybe another green from laserlands soon if i get some cash :paypal:

check in the back of a projection tv theres a huge piece of fs mirror i used some to build a spirograph lately just gotta know how to cut the glass :horse:

jayrob's picture clearly shows where the red and blue module's go just look at the link provided by lonewolf. the rectangle prism is what your talking about and the cube dichro is what combines blue and red then that beam reflects of the turning mirror and through that same prism green passes.

yeah i think the dichro in the phr is a pass red reflect blue/violet. all i would have to do like in his picture is reposition the turning mirror then put my green and blue through it. i am going to eventually make an rgb but right now all im interested in is blue and green for a school project...

will those sleds have the optics to combine 532nm and 405nm beams?
