Hello, I have been planning to build a laser for quite some months now, but I ended up spending almost all my money an a mechanical keyboark because my old one broke. For now, I'm planning to do an S4X build probably around November, as my allowance is only 50 cents a day so it takes a...

Thanks for the reply, that's good enough :D. I just wanted to see if that heatsink had a good duty cycle or else I would buy the copper heatsink.

Hello, I am planning to do a single mode 450nm build, with a Survival Laser C6 with an aluminum heatsink and a G2 lens, with an Osram PLT5450B with a copper module and a microboost at 275mA from DTR (should be ~300mW). What would the duty cycle be if I apply thermal paste between the module...

Sorry, didn't notice that. By the way, I don't really trust that tool, it says 70mW of green is 13.11x brighter than 100mW of red, but for me the red is about 1/3 - 1/4 of the brightness.

Nice build! How does the beam visibility comprae to a 100mW green?

Thanks, but the Sanwu goggles CAN be worn over prescription glasses :D. I PM'd Podo about it and he said they can.

Thanks for the reply. Unfortunately, the safety goggles on Sanwu aren't slip over, and I wear prescription glasses. I am pretty much blind without them. Are there any cheap slip over goggles available for 532nm?

Thanks everyone for the replies, but I'm not sure if I will get it at all. My dad doesn't like the idea of me having a class 4 laser. Might just get another green 303 and safety goggles from Sanwu and be careful to prove that I am responsible with lasers. That thing had a really visible beam...

Hi Podo, which laser should be brighter? The green 304 or the 250mW 650nm pocket with G2 lens? I might buy both of them around Christmas. Also, does the Pocket come with a battery? Thanks

Hi, So, this will be my first build. I am planning to do a Survival Laser Bargain host bundle with an Osram PLTB450B. I want to choose the 530mA driver, so I get used to the power, and later upgrade it to something like 1A. Thing is, i saw DTR's power test and at 0.5A it says it is using...

jbaughb I saw your message and I didn't order it because I read posts saying it is a scam (just in case you don't receive my email.

Thanks but do you have any link to him? I can't find where he sells them. UPDATE: I think I found it: https://innolasers.com/shop/index.php?id_product=9&controller=product Is this the one?

LOL I've heard of Dr.Lava but they say he doesn't sell them anymore :(

Hi, sorry for the n00b question, but could anyone tell me where to buy a Microboost driver and how to set the current to 300mA?

What a coincidence, I had already planned to use a SL C6 Assembly before starting the thread :D

Thanks, that should be ~300mW of single mode 450nm goodness :D

Thanks, I might use it for a build in a month or two but I'm kind of paranoid about the current.

Hi, does anyone know what current is the driver set at here? (the one with a 3-element lens and a driver)
