Hi Rich - is this one still for sale? Would it be possible to use this one for a case-positive diode? I've got a lovely 503nm one that I bought from Jnrpop and it'd go nicely in this host :)

If you're able to measure and set up a diffraction grating in a decently precise way indoors (or measure long enough distances and have a large flat wall & a friend to help outside), you could measure your lasers yourself with a cheap diffraction grating ordered online. Apply a bit of...

Certificate's not a local problem - but yeah, seems that it'd be connected with the upgrade rather than an actual attacker :)

A British artist called Stuart Semple who was unhappy with Anish Kapoor's exclusivity on Vantablack came out with this product which he calls "Black 2.0". http://stuartsemple.com/project/black-v1-0-beta-worlds-mattest-flattest-black-art-material/ Basically it's a poor-man's version of...

I got maybe an hour of "this page is unavaliable" on every thread, but it seems to have gone pretty smoothly :) Also had the same warnings as you GSS, certificate was expired according to Chrome for me...

Post your intro in this subforum - that way people will not ask you to do it in the future as they'll be able to find it. Then I strongly reccomend you go and read and comprehend all of the sticky threads in the Welcome and Sticky subforums before you post again. Seriously - being rude will...

I suppose the question becomes - is there a similar material that's less exotic that can be welded with copper in this way? i.e showing that same aesthetic but not costing as much?

That is some beefy Nb-Ti cabling... I visited CERN in 2013, and they had some bits of the Nb-Ti superconductors on the LHC ring to show us on the tour - a thin cable of Nb-Ti about the diameter of a pencil was rated for 13,500A of current when cooled. Equivalent copper bundle had a diameter of...

Yep - I'd mirror XquantumTheory20's sentiment. You'd be better buying a JetLasers PL-E Pro or PL-E Mini instead, it's a similar design, but at a much more reasonable price and arguably equivalent or better build quality. Wicked Lasers has a poor reputation here, and tends to overcharge. If you...

Hak - it shows it when you hover the mouse over someones username - it's not perfect, but it's not bad either. Obviously it still is prerequisite that the user's filled their location out on their profile...

Double post was back in August 2017 - not sure whether Xqt2019's necro is more obnoxious than the DP here :)

For a laser diode to "go LED" that means the internal structure of the diode is damaged enough that it no longer properly lases - it'll put out a little splash of light, but it's never going to work properly again. It's dead. If all you want is a working laser, you may as well buy a new one -...

It's going to be a pretty invisible laser display if you use a 5mW module - You'll need a dark and hazy room to see even the faintest whiff of beam, but the dot will be visible just about. The low-power blue diodes aren't avaliable at low cost since there is not demand for large-volume...

Are you configuring the LM317's for constant current not constant voltage? You should be setting the current on each driver, not the voltage. Constant-voltage drivers and laser diode's dont mix so well as LDs have a negative temperature coefficient (as their temperature rises, their resistance...

I'd use the search box to look for threads before asking questions outright, as there's a fairly definitive guide thread on combining beams here; https://laserpointerforums.com/threads/reference-guide-how-to-combine-lasers.77449/ Edit: It seems as if you may not have read the sticky threads or...

Can you attach a picture of the projector?

May i suggest Ninite.com as a fast way of reinstalling everything* without bloaty installers etc. *most common free programmes

Was it an old licence key you lost or something? If you can't get a replacement (or a 365 activation through work :P) then there are some passable free alternatives - LibreOffice has always worked fine, although may take some getting used to.

In the picture it's almost indistinguishable from the anodising on that host... Really neat work.

why do you need a 445 specifically? The best cost-to-beam specifications will be found with cheap 532nm DPSS modules, I'd have thought...
