    Videos you wish to share part two.

    While we are on the topic, here is last year's small show. The GoPro picked up the 360 degrees of audio pretty well.

    Videos you wish to share part two.

    Not currently, lasers have worked to ignite fuses, but have only tried to do it up close :cool: (and had to clean my lenses after) :confused:. You would definitely need a tripod for anything over a couple feet. I'm going to have to try that RC Relay idea, it looks much simpler than what I've...

    I got kind of obsessed with rockets a few years back and made a rack of my own to launch them.

    Post your random pics!

    A coworker gave me a MagLite to use for parts (the switch) because the inside was so corroded that the tailcap wouldn't budge. So I introduced it to the bandsaw. 🤣 So that's what the inside of a battery looks like..

    Enchanted Beams Thread

    I was anxious to get some shots this weekend as the snow finally melted.

    Back from 2014...man prices have changed

    I have a Sharp 488nm doing 139mW (The link to the build is in my signature.) It is definitely a unique wavelength that you need to see, my camera has a hard time capturing it. From what I've read, they can run from 486nm to 493nm as their temperature changes.

    Another bad idea

    I was going to post a thread on this, but I just found yours. A few weeks ago, a friend was showing me that his wife got him these for Christmas. I was actually surprised to see that unsafe junk like this is being sold. I didn’t get a pic, but because of the super unfocused beam, I had to...

    Sale thread/ Hosts/Heat Sinks/Focus adapters/lasers

    That Hex host is definitely unique, I like it. That's one host you'll never have to worry about it rolling off whatever you set it on!

    My Very First Laser Build!!! --- 445nm, 2W (M140), my "Alternative" Laser Host, and Analysis of Build Cost!

    Nice job with the DIY! I like the key switch. I also recently did a similar diy build in the thread "DIY Project Box Enclosure Build". The 1/4-20 thread to mount to a tripod surely does make aiming it so much easier!

    New drivers by me testing and suggestions thread.

    That's cool to see someone designing drivers! 20mm is the most common diameter that I've used.

    DIY Project Box Enclosure Build

    Here is a project I did earlier this year prior to my 7W NUBM44 Maglite build. I had a couple of weeks off work and wanted to try something that could be done without the assistance of a machine shop. The host (if you want to call it that), was an “Aluminum DIY Project Box Enclosure Case” found...

    7.3W 450nm NUBM44-V2 Maglite Build

    Nice! I haven't attempted a cycle of over one minute on + a few minutes off. At 1 minute, the outer diameter of the almost 2.5" heatsink starts to get warm, so I know that the copper module on the inside has to be scorching hot. I've etched my name in a car tire years ago with an M140, so I...

    Thanks! I like your host too, looks very clean!

    Guide: Where to buy 18650 & 26650 Li-Ion batteries

    I've been buying imren 21700s from liionwholesale. The 21700s have a good capacity and fit all of my hosts that use an 18650 + spacer. Pretty good prices and good selection of other sizes. Shipping cost is a downside though.
