ok, afraid to say that i screwed up big time. i soldered the driver to laser and tested, it works sweet, now i needed to put on a spring for battery contact, ripped apart a old remote and used the spring from that it was to big so i cut it down till it fit tried to insulate the whole lot so...

spent the last of my money on 2 sleds, but i did try the cells i got out of a laptop battery think they are 17500, they where not even close to being able to fit. i will try a improvised way tomorrow as im tired

i wanted a unique laser so i went looking for a strange item and came across a 50cal casing, and heres the build well sort off anyway, if my writing is crap, sorry i just don't do this kinda stuff often. 1st picture is after i struggled to cut through the casing with a wannabe dremel :D. In the...

that 405nm diode only needs 4.5v dont try giving it 7v. I have never heard of grove 2 driver but after some quick research seeing it has a vdrop of 1.2v+405nm diode 4.5v=5.7v you would only need 2 of those batteries, you could use 3 batteries as this driver supports up to 12v, but why waste...

Contradicting myself here but anything above 5mw you should invest in some laser safety glasses, your more likely to find a 1w> 445nm laser cheaper then a 50mw as there is a certain projector where the diodes get harvested in big quantities. Also a laser is focused light (not something for...

wavelength is also what will affect the brightness of what you will see example. 532nm green diode 50mw 808nm infrared diode 1w because our eyes only see up to 700nm (apparently) the green laser will win in terms of brightness. And yes there are different powers for each diode, 10mw vs 50mw...

That looks cool, looks front heavy with all that heatsink :D just a idea, instead of using the tiny heatsink on the NPN is there anyway for you to attach it to the main cooler using a non-conductive thermal pad?

"impairment of health or death from radiation by reason of the fact that it emits radiation" I hope they realise this is a laser, impairment yes but death is over the top after all this is not a James bond laser :D

Thanks for the welcome :thanks: with the yellow project, I thought i could just combine red and green laser beams through a dichro < would that work?. That project can wait though as i have just brought a LPC 815 sled and a PHR 803T sled for £14.03. Also trying to get access to a lathe to make...

Hello LPF members, this is my first time I have ever introduced on a forum so hope this is ok, my name is Adam and im 18. I have great interest in electronics(I self taught for 4 years and then 2 years in college). I have a 405nm PHR803T diode that I think I have killed at some point :thinking...
