    DIY Zilog Z80 computer as a hands-on project...

    I am going to make my own Zilog Z80 based computer just for sh*t and giggles while also learning about the computer history at the same time. So yeah, I am sure this one wouldn't be the first Z80 related project that got posted here. And I am not that old. LOL But, still the computer history...

    Osram PLPVQ-940A driver question

    Hey all. I got my hands on an interesting VCSEL diode (Osram PLPVQ-940A) from Digikey website for almost $10 for the DIY Infrared illuminator for some of my digital camera so I can use it for certain night shoots without disturbing anything in the dark. It's powerful for such a tiny laser -...

    Any LED flashlight style (center positive) 16.8mm boost laser driver?

    Like the title, I am looking to see if there's a potential seller for the adjustable current boost laser diode driver in the 16.8 millimeters round LED flashlight driver style packaging (center positive) for the 505nm laser diode I haven't mounted yet, and I am allowing DTR some time with the...

    A question about Nikon D3400 DSLR camera regarding beamshots (LED and / or laser)

    I am wondering about the Nikon D3400 DSLR camera's white balance settings regarding the beamshot of either nearly monochromatic LED flashlights and / or lasers; is it best to edit the white balance on the computer via RAW (NEF) file (Darktable on Linux computer - similar to Photoshop), or just...

    Curious question about Osram PLTB450B theshold current (?)

    Since I have the Osram PLTB450B 1.6 Watts 450nm blue laser diode, having messed around with it long enough, that raised a curious question; is the lasing threshold current as specified in the datasheet as 200 milliamps or is it merely a speculation? In my case (and in this picture), it's very...

    Wanted - 17mm round laser driver

    Since Flaminpyro's now MIA, I am wondering if you guys would know of wherebout that I can purchase the adjustable boost switchmode laser driver in the LED driver style / layout (17mm round, and positive terminal center and negative ring, just like the LED drivers) - I would like to be able to...

    Feeler thread for custom 26650 host price

    I am wondering about a price tag estimation of a decent x2 26650 Lithium-ion cells laser pointer host - I would like decent lathed host made eventually, however I want to have general idea how much they will cost me in approximation when I want it made by a LPF member here. Aluminum will do...

    Feasibility of diode-pumped dye laser (just a thought).

    Like it says in thread header; it's more of a thought. :thinking: I was wondering whether if it's possible to use the green - blue Gallium-Nitride laser diodes which are nowadays powerful and cheap (true blacklight laser diode is of course prohibitively expensive so I won't bother covering it...

    Convoy S2+ Laser host question

    Before I buy the parts for a 505nm aqua laser, I am wondering if the Convoy S2+ host could as well suit the laser itself (and it will be picked in the green color too) as I have several 18650 Lithium-ion batteries I can use, especially the pricey A123 18650 Lithium : Iron Phosphate cell which is...

    520nm green laser diode in holography usage

    Since the holography usage was mentioned in the Osram PL520 50mW diode datasheet, I was wondering if anybody here perform the hologram imaging with this particular diode (instead of either the standby lasers; 632nm orangish-red Helium-Neon laser and / or 635nm red single mode laser diode), and...

    Copper Vapor laser switchmode PSU opinions

    Alright, since I have couple high-ampere IGBTs lying around, along with PSU-related chips, I figured I would ask here for the opinion on high-voltage step-up SMPS for the eventual Copper Vapor laser I may assemble at some point. So, which output driver stages would be preferable? I do have few...

    Hello. :D

    I am a long-time lurker of this forums, and I gotta appreciate it being the place whereas I can find the answer for, like the ruggedness of a In : GaN 405nm violet laser diode for example. Now I have decided to be a member of LPF here. :D Now, about myself... I am a hearing-impaired person...
