Hi everyone. Figured it's summer, so it's time to clean out my garage. Here are some items for sale. Assorted First Surface Mirrors As seen above, there are seven mirrors of the same shape and size, and a few other mirrors that are varied in size. The similar mirrors are 1.5" long. Price...

Hi everyone - I'm going on a cruise with my fiancee in a few days, and I thought it would be really neat to bring some lasers aboard so I can take some beamshots over the ocean (my fiancee being an amateur photographer). I checked online, and it turns out that lasers are prohibited aboard most...

Hi everyone. I know I haven't posted in a while because I've been really busy with school and the fiancee (recently got engaged!). Anyway, I basically haven't done anything laser related in about a year, so I figure it's time for me to sell most of my equipment and things I am not using - I...

Hey everyone. I've been hiding this update for a while now so that I didn't get anyone too excited. But, now that they are due to arrive any day now, I figured I would make the announcement. BlitzBuck V4 Note: You'll notice one of them has some solder on it. That was one of my test boards. It...

Hey everyone. We all love lasers here, we all know that. But how many of us get to work in a state-of-the-art laser research lab?! I do! A few days ago, I received an email from the physics adviser at my school (I'm a physics/math major) informing me (and other physics majors) of a new upper...

Hey everyone. I was looking around on KickStarter and stumbled onto this: Oscilloscope Watch by Gabriel Anzziani ? Kickstarter I thought it was kind of nifty. It's not the best oscope (only 4MSps), but hell, for $125, it's quite a deal. What do you guys think?

Hey everyone. So a few days ago I decided to take a risk and bid on a Bosch and Lomb monochromator. Anyway, long story short, I won it for about $230 and it arrived today! Without further ado, here are the pictures that I know you guys have been waiting for! The Monochromator! Now, that's...

Hey everyone. I figure that I should have done this sooner rather than now, but I wasn't sure how much interest this would garner. In my I "C" Red entry, I used a very unique driver design that allows me to have power modes (eight modes total) without the use of a PIC or microcontroller. While...

Hey everyone. I got this brilliant idea today, and I need a special machinist to do it. I'm looking for a glass host. Yup, you got that right, a glass host. I'm thinking it will be a typical host shape (flashlight like), but made of glass, with the exception of one strip of metal running along...

Hey everyone. So I recently got the PGL-III-C 671nm from the CNI GB that Bloom ran (by the way, thanks!). I don't have many pictures (no good camera), but you all know what a PGL-III-C looks like anyway, and because this wavelength is beyond 660nm, it basically looks like a deep red. Hard to...

Hey guys - My Tenergy 2x li-ion charger is finally in its last throes of life. It used to be a 2x charger, now it'll only charge one at a time (no idea why). Anyway, I figured I would finally get a smart charger, ideally one that can charge up to 4 li-ion batteries, with different current...

I know this doesn't really belong here, but I feel it's necessary for those who want to work with drivers. I've never actually understood the physical mechanism of a transistor before I read this article. It's a great read and very well explained. Here: SCIENCE HOBBYIST: how transistor works...

Hey everyone. I know I'm not the biggest fish around here, but I was thinking of changing my avatar to something a little more unique. Would that throw people off? For those that know me, would it add confusion? I feel the laser-related avatar is tired and looks the same as everyone else's. Or...

Hey everyone. So I was taking a look at some ICs over at Linear Technology and noticed that no one had ever introduced a charge pump driver into the forum. I experimented with them a while back but decided that they probably wouldn't be wanted enough by the forum to warrant the effort of selling...

How is everyone fitting these in builds with the new 5W reds? To get it to focus to infinity, you would need to have it be 5cm (2 inches) away from the diode. Your lens would need to be huge. How is everyone doing this? Why can't we use a shorter FL lens? I realize that we won't get as nice a...

Hey everyone. I was thinking that it's about time that a FlexMod replacement come about. I recently saw a thread where it was required, I thought that maybe it would be about time someone came up with a reasonable linear driver like the FlexMod. Then I figured, hey, why not me? I'm just...

Hey everyone. So the recent past have been good to me with regards to lasers! Built my 520nm laser yesterday (in the Green forums) and got my ML argon ion from Dave today! Both of these were birthday gifts, so I am happy! The laser I got is fantastic. Plug'n'play from Dave, has all six standard...

Hey everyone. So I have decided I am going to start converting my laser collection to gases and solid sterling builds (besides CNI builds, unfortunately). My first one is in my signature, the 445nm build I did. That one turned out great. This one may very well have turned out better! It...

I guess it can happen to vets like me too! I had finally got my 520nm laser built using the new diodes, and it worked perfectly. The window was a bit dirty, which was confusing (not sure how it got dirty - I kept it in the package until I was ready to install it into the laser). After I...

Hey everyone. I figured that since this project isn't getting under way, I would sell the IR bar for it. Anyway, I have a 40W IR bar, capable of running up to 45A or so (haven't tested it above that). It was in new condition when I got it and hasn't seemed to degrade since then. It's a lot of...
