Been out of the hobby for several years now but after firing up a few of my old ones I decided I may want to hop back in :) I'm looking at an LPM in the < $200 range, most people have seemed to recommend Laserbee or Hyperion. Hyperion seems to have stopped selling, so I'm guessing it would be...

Hi all! After going dead for several months (school sucks :/), I have returned and still have 10 of these diodes untouched and spectroe'd by Paul. These bad boys will run you $24, and 7$ express shipping Here are the wavelengths for each diode, you can request a certain one if you'd like.

Do you ever find yourself browsing through AliExpress, and stumble upon something that seems too good to be true? Because I do that a little too often, and is probably why I have no money. Anyway, behold the cheapest actual 450nm pen I’ve ever found, at $22 from AliExpress:

So I understand that after posting this thread, there is some interest for some more of these diodes. I ended up paying sround $285 base for the one mentioned in that thread and 35$ for "dhl express" shipping, and around $7 more to ship to paul to be tested. Should there be sufficient...

I got this email today from this one supplier that at this point I'm not even sure how I got into contact with them... They've literally been sending me the nonstop "are you there" spam for the last year, but today I got an interesting one promising a "Osram PLT5 488nm 60mw 5.6mm brand new laser...

Hey guys, long time no post ;) Anyway, I emailed a supplier probably 2 years ago about a diode, and they finally got back to me and sent me a list of diodes that were surprisingly very cheap($24 for a 7875!). Among this quote were some that i had never heard of such as the NDG7K75T. Looking...

http://arstechnica.com/tech-policy/2015/11/new-york-city-bus-driver-hospitalized-after-passenger-fires-laser/ So now they've advanced from airplanes to bus drivers? Unfortunately this article has almost no useful information as to what really happened but its still painful to see how stupid...

This recent Friday, i came into contact with a lady who had some old lab equipment from a nearby place that had shut down. Luckily, I happened to spot the "532nm" written on one of the boxes or i wouldn't have even bothered. She noticed me talking and asked if i knew what it was and long story...

I'm looking to make a driver for my Mitsubishi g84. I have been browsing every article on making one, and have learned the following: 1. The lm317 won't be enough because it can only supply 1.5A 2. The lm338 will be enough 3. 1.25(ref voltage)/2.4 = 0.52ohms? I don't think i calculated the...

I cant post mine right now because im taking a time lapse but feel free to share yours!

I know there's a thread like this for photos, and thought we should have one for video too. Just to be clear this is YOUR random(doesn't have to be laser related) video (although that gave me an idea for another thread). I'll start it off. Heres a quick one of me testing the default wicked...

I was wondering if there has been a thread on this, if not (is there a reason/legal?) then this could be it. As far as i know: C@5io XJ-A140 C@5io XJ-M140 I'm assuming the others with similar model numbers?(m150/m250 and such). The other reason i say this is i'm looking to get one and do a...

It's using a crazyspaz m-140, and a wf501b host from budget beams. Build: Putting those ridiculously good silicone wires through the hole. Heatshrink for the diode. Soldering the first wire Heatshrink ;) Second wire Forget to take pictures because you got to into the zone...

more videos/ and some beamshots(at night) to come!

well my source of financing for my laser hobby is actually youtube. I transcribe the songs from a game called geometry dash when im bored. i made this one yesterday:

For those of you who saw my first thread: http://laserpointerforums.com/f50/first-build-sort-its-altoids-93851.html, I've since rebuilt it to address some things that were bugging me, namely: 1. Duty cycle was about 45 seconds on/off Now unlimited :) 2. The battery pack was glued outside of the...

I know this is probably a question hat wouldn't be well recieved so i took it to off topic: I'm trying to write up a page on efficiency for the wiki and i was wondering if anyone knew what the current diode that averages the best electricity->light ratio is?

I just ordered one of those black aluminum housings thats usually listed as "stage laser", one such is here: http://www.ebay.com/itm/33x33x50mm-Laser-Module-Housing-for-5-6mm-TO-18-LD-with-Lens-Aluminium-Part-/191353474393?pt=LH_DefaultDomain_0&hash=item2c8d8e4d59 I seem to have figured out how...

I'm not sure what to make of this one... I have been having an issue with this one dimming shortly after use, and the working time only got shorter. I tried to see what the issue was and on defocusing i would see what appeared to be it dimming, then like cells dividing, another beam appears and...

This thing is amazing! i highly recommend it to anyone! Don't be like me... order good batteries before hand.
