Hey Guys. Acquired some linear bench PSUs numerous years back (#1) and reaching the limits 5.1A on some diodes were I would like to go a tad higher as my voltage on some diodes' is still quite low and looks like there is more optical-gain. and wondering if you can daisy-chain these to double the...

Thread still topping the 445forum as top thread, - IMO a joke this dumping on new users. #44 2 posts and gone, tsk, wonder why' because of what he necro-started an old thread that was relevant to the beam-problem he felt he had as a new laser-owner... and it's even 2 moderators that are...

Sorry for necrohumping this old :devilish: of a thread but not much thread activity on 0AT Do you have an active video link as the YT-demorun above seems gone with the wind? I reckon it's these 4.7w Nichia 0A / OAT there are in many of these China CNC PWM/TTL labby's from China this year, that...

That blue light of massless particles, looks wicked and like its painted on.. another Osram PLTB450B build driven conservative, where im fooling around with different screw-on-LDsinks attachements and testing the use of indium, copper'grains and solderballs in trying to close as much of the...

if the price is equal' amongst 05,06 and 08 LDbanks on a attractive single-offers' is there an obvius choice' with our hobby as "handheld lasers", and that is the intended purpose and not just take it on the fly as to nominel-effect. Are certainly not on call with the pro & cons when it comes...

the new double threaded-screw-in-diodesink works good :beer: and makes it a lot easyer to change diodes with wth the use of RC-plug to the LDpins. (high C'rated lipo-plug & silicone wires)... Housing a PLTB450B P8MAX cam LE2M cam. Looks wicked how deepblue the PLTB450B diode delivers at...

Jerry all of these issues have been adressed by Korad with stronger trans in newer batches...(was down to an lacking 220v trans(not the aussie model), being tortured by the max'amp on a hefty 240v aussie juice) on EEVblog the Korad seems to be hands-own the best budget psu with the price in...

PLT5 450B single mode laser from above-picture. an retailaluhousing with an alubacktrigger with an cobber-module inside and radial heatsink at front. clocking in at 197mA at tailcap DMM on mA-setting and 0.169A on (10A) Amp-setting //2xAAA. (often puzzeles me why multimeters-values differs from...

bummer, 100buck, damn thats a lot. but then again, also of respectable and tested backland if you aint doing it on the fly with el'cheapo parts and sleds like myself) have just finishing up some 405nm buildsx12 and x16s and are as noobish as they come, but aint got much budget for each laser...

S06J X12 on left-beam right along BDR209X16 in the right..(plain' no fog or likewise) Huawei P8max mobilepicture on standard setting X12 & X16 X822 LE2M mobilepicture std sett.. X12 & X16 a stander comming short with close to 1kg of metalhosting dangling.. backplate, so i dont blind any...

finally got that S06J x12 diode to play along. beam shot S06J X12 on left-beam right along BDR209X16 in the right..(plain' no fog or likewise) Huawei P8max mobilepicture on standard setting X12 & X16 X822 LE2M mobilepicture std sett.. X12 & X16 a stander comming short with close to 1kg of...

Hmm, the driver on the PLTB450B-build at relative low current, was not that fund of my thin transperrant heatshrink and the heat from the power simply heated the flowsoldering to a point that the transperant shrinkwrap moved it out of place. (picture) was running in the ballpark of 1.1 to...

god damn, the +pin breaked off (left one).. it looks like a fiidle nightmare in trying to get anything to attach to that little restspot on the diode.. assume many users have been in that situation with diodes that have lost one of there pins, any recommendable way in trying to salvage this...

Damn. all over the place in getting these diodes pressed in a bank-up old brass/copper pill and these 3.8mm BDR209 that looks like dwarfs with these short legs, quite a hazzle with that length. finally got the hole-pressure-tool to push it true with a bang (not ideel I know), but ewen thow it...

sounds promissing just have in mind the XXXXXXD-model is without computer management (while with an P endmarking they are with RS232 /USB interface and free software) and the KA models doesnt got the joystick(click/turningwheel)interface that are on the KD model that makes the adjustment a joy...

Yes, but as i notice most of the lesser linier PSU in this sub100U(delivered)level got som spiking. The KA3005P was check by EEV blog, and as i reckon it did decent when it come to spiking.(though' with the pricelevel in mind) but i have also notice that the majority of the...

Have also jumped on numerous bluray diodes, now that they are in another priceballpark.. Got some of the lesser S06J and numerous BDR209 and some still in the sled, and yep its alsmost a shame to crank that nice sled up for these high powered bluray-short-leg-dwarfs, but on the other hand there...

Re: Killer deal on USB spectrometer! here 1½ months later, any development on this sub100US (delivered) USB-spectrometer.. http://www.thunderoptics.fr/web_documents/to-mini-usb-tg-640-xxxx.pdf there Ebay-feedback seems legit and numerous transaction solelly this last month, so I doubt that...

Certainly an old thread, but since its sticky and just hanging there in necrofileland, still room for own approaches. I dont own an LPM.. been thinking about jumping on one for some years, and patrtically since they TEC-based-ones, seems to be acces-able from around 70US (certainly attractive...

For sure' you gotta love or hate aliexpress but it is certainly the wild-west when it comes to diffuse specification taken out of the blue air. - and also not too solid when it comes to buyer-rights where its an timefraction of a few weeks you actually can make the dispute. Certainly are many...
