    559nm Build in Vintage Flashlight

    Oh, wow. What happened to jayrob? He was one of the artists here, for sure. Yeah, I've seen the 473-488 diodes. I have one in my cart from DTR at the moment. I remember when those were unobtanium. 473 is such a pretty color. I have one of the 473 bench lasers, but want to do a...

    559nm Build in Vintage Flashlight

    ZRaffleticket! Good to see you're still here, man. I've been away from the hobby for a while, but am cycling back into it again, seeing what's new, and am planning some new builds. (Every time I leave and come back to this hobby, it gets so much better.) You were the one who inspired me...

    488nm Sharp Solarforce Build

    Ooooh, 4/8/12k paper. Very cool. So when you polish in the lathe, you don't get bands or rings? I tried using a drill, but found I needed the randomness of a hand pattern, to avoid streaking. But I arguably wasn't being very careful. Do you do it wet, or dry? Good tip on the Krylon...

    488nm Sharp Solarforce Build

    I don't like to swear often in my posts, but good god that is fucking awesome. Amazing job. Really well done, on both the idea and execution. EDIT - Can you talk about your polishing technique? I mirror polished the heatsinks on some of my all-copper builds, and I found it hard to get that...

    Returning member here

    Ok, but how? The max person here after the several years I was here had just barely hit 1000 rep (and that took a lot of work). Also, I know from other forums I'm on that use the vBulletin software, that there are mechanisms that prevent small groups from repping each other and abusing the...

    Thanks to all who chimed in. Most appreciated. So can someone explain about the rep system maxing out? When I was here before, it seemed to make sense. It wasn't easy to get tons of rep quickly (you had to earn it), and Cyparagon was the rep king. How/what changed

    Ha. Regarding drama, I actually wasn't referring to anything specific, as I haven't read up on much here yet. (And I don't necessarily consider it a bad thing, as I know any active community will have some friction, as part of just being active.) But I was/am curious if there have been...

    Hey Alaskan! I actually remember when you were new here, and you lived in Alaska, haha. :) Good to see you're still here, and a mod now, too. Very cool. I never really forgot about this place, as I still have all of my lasers, parts, and equipment, and still love all of my builds. I...

    Hey all! Returning member here. Been gone for about 3 years(!), but haven't forgotten the hobby. Decided to poke my head back in, as I do miss this place, and was curious how things have evolved. Not sure if any of the vets remember me (see pics of some of my vintage solid-copper builds...

    Can i take my TK75 on a JetBlue plane??

    Sorry to be late to the discussion, but I figured I'd chime in here. I fly JetBlue regularly, and have transported lasers between BOS and SFO on two occasions, both times in my carry on. I had a 400mW green from Lazerer, and the other was a 2.5W blue that I built in a solid copper vintage...

    NDB7A75 w ball lens - $120 shipped on eBay

    445nm 450nm 3 5W 3500mW Blue Laser Diode LD to 5 ?9MM Nichia NDB7A75 w Ball | eBay I know some folks have started playing with extracting these from the new monolithic projector heatsinks, but it looks like Laserlands has them available loose (or already extracted). Seems like a decent price...

    SuperBoost Drive (5.5+ amp boost driver)

    Re: I need to gauge interest. Please comment. I'd be in for one or two. I support your work, man. We need more folks like you on the forum. (And more good driver choices out there.) -Andy

    Sold

    I really wish people would leave their for sale threads intact, and not just delete or replace them with 'sold' when the item sells. (I'd prefer to just see 'SOLD' added to the original title.) It's valuable historic information (not to mention interesting) to know what was sold, when, and...

    Any ideas about Digital SANWA LP1 Optical Laser Power Meter

    The Laserbee will likely not be a very good solution for measuring lasers below 5mW. Because of the sensor it uses, it will take 25-30 seconds to heat up the sensor, and this will not work well or accurately for low power lasers (which can't heat the sensor much). If you truly want to...

    Any ideas about Digital SANWA LP1 Optical Laser Power Meter

    That meter is meant for measuring very-low-power lasers (e.g. for optical communications), as the maximum rated power is only 40mW. Likely not very practical for our hobbyist needs. For $30-40 more, you could buy an Ophir sensor (like the one below), and with a DMM and two 9V batteries build...

    No longer WTB: C Mount 5W 650nm Laser Diode

    Re: WTB: C Mount 5W 650nm Laser Diode Apparently these were notoriously fragile. IIRC, several people had them die after 'normal' use (i.e., not severely overdriving them), which was not fun, given the ~$400 price tag. I think this is why Jordan stopped carrying them (and why you might not...
