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

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.

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..

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

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.

Yeah, definitely small world!

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...

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!

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!

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

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...

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!

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.

Here is my current setup for taking pictures with this beast. Yes, that is a microphone stand that is holding the huge Maglite build ;). None of my C-Clamps were big enough and I didn’t trust my other tripods to support its weight. Also, a Sanwu 3X BE was used to tame the divergence of the...

Hey guys, here is another project I completed this summer. This is something I've been wanting to build since the 44-V2s became available. I've been holding off on posting this until I could get some decent night shots, and we have finally had a solid week of crystal-clear night skies! The host...

This one must be on the higher side of the of those wavelengths, it definitely has a green tint to it. The GoPro just has a hard time picking it up.

Here is another build that I made this year using a 488nm Sharp GH04850B2G. I machined a small heatsink and affixed it to the threaded insert with Arctic Alumina (it works ;)) It was a DTR packaged diode/ driver, I'm not sure which driver it is or what it it's set to, based on his...

To answer your question Alaskan, (for these long exposure shots) the NDG7475 does have somewhat of a blue hue to it when photographed alone, but I think it is definitely the camera. So almost a week later, we finally had a clear sky last night to re-take some of the pictures. While the GoPro...
