Hey guys I'm thinking about building another red laser since I have a 24x burner on hand, I know it would be easier to buy the harvested diode, however I already have the burner. I noticed from threads on this forum that the diode is in an odd shaped heat sink, can the heat sink be totally cut...

Hey guys i was looking at some homemade laser shows and wanted to build my own..i like the galvo system the best as we all do and was looking as the cheapest way to get it done..i came accross a video on youtube where it seems to me that the guy is using regular full turning motors and still...

Hey everyone i need to know how different drivers work.. I know that some drivers need voltage to work so therefore the output voltage is lower that the input..can someone please tell me which drivers do this.. I know the Lm317 driver needs voltage to work so therefore its output is lower than...

Hey everyone, im thinking about building a blu ray laser..i have build red lasers from DVD burners before and all went well..so i want to try a 405nm before i go to 445nm.. Im thinking about using the PHR 803t diode, is this a good idea? Or no one uses this anymore? Im asking this because im...

Hey everyone i know this is a question that has been asked many many times, but i cant quite find a definite answer..i want to build my own test load, here is what i am thinking about using.. Diodes Resistor Im hoping to build a test load that would test up to 3Amp, so i can do all my testing...

Hey guys im doing some research and lloking for stuff to build my first 445nm laser.. I was looking on ebay and some CHEAP stuff caught my eyes..can anyone tell me if they are any good? Thanks guys.. Diode Driver Lens Another Lens Thanks again guys..

Hey guys is this laser driver any good? Im thinking of using it on my red DVD diode..or two in parallel for a 445nm diode..the reason im asking about this one is because its cheap lol..but is it any good? will it really supply 500mA current? Thanks guys.. *Laser Driver*

Hey everyone, im addicted to lasers lol.. Anyways i need some help understand somethings..i have some knowledge on some lasers..example i made a red burning laser.. I have some cheap 5mW green lasers.. I really like beam pointing, and from what i understand green is the best since the human...

Hey guys i bought a green 5mW laser of ebay and it works very well..can see a visible line at night and im very impressed by it..so i decided to buy a few more..however i noticed that two of the new ones i bought are much much dimmer..im able to see the green dot, but no visible line at...

Hey guys i finally put together a red laser..i got the diode from a DVD burner and im using a driver i got from ebay.. Driver I didnt have my DMM with me, plus i didnt know what was the required amperage, so i started low and gradually raised the amperage to a satisfactory amount.. Im powering...

Hey everyone, i got my hands on a few dvd burners and planning on building a red laser, i already have two aixiz 5mw laser and i ordered to driver of ebay..i have a liteon dvd burner..im not sure of the speed of the burner or any thing much..it has DVD+Rewritable R/RW to the back it says...

Hey guys, does anyone know if these drivers are any good? and can u all please tell me what diodes they are compatible with and how do i go about setting them...any help would me greatly appreciated.. Driver Link 1 Driver Link 2

Hey guys, sorry for the noob question but i really want to know before i go out and spend wasteful money.. If i purchase a cheap 5mw green laser of ebay and then i purchase a stronger green module (50mw) and swap it with the one in the 5mw laser pointer, would i now have a powerful 50mw green...

Hey guys am trying to build my first driver..i id some reading on them and i would just like someone to help me confirm that these are the right pats to use, thank you.. LM317 Variable 100 omh resistor 1N4001 Diode 10mf 16v Capacitor Im not sure if this surfae mount is the best... And well...

Hello everyone, im sorry if the title is misleading, but it was the best i could think of... I recently purchased a 5mW Green laser pen of ebay (i have not recieve it yet though)...i dont know much about green lasers but i do understand that it uses an IR diode and crystals to get the green...

Hello everyone im looking for an adjustable setting drive, like a rkcstr..can anyone let me know where i can get it for the best price? im from Trinidad (in the Caribbean).. Im also looking for a green laser pointer, i was advised to purchase one instead of building one..can anyone let me know...

Hello everyone im new to the forum and i have a few questions...BTW great forum... I would like to build two lasers...the main reason is for pointing into space, im into astrology and when using the telescope i would like to point it up to the sky when poining out stars to my friends... Ok so...
