37mm Camera Launcher Questions and Answers

So there have been some questions going around about the 37mm launcher system.  How does it work?  What are the components?  Etc.

Well, Vlad, my partner in this venture, has written up a bit of an explanation where he got the original idea and goes over, in some detail, some of the components.  It’s at http://hacksrus.com/~recompiler/tars.php

Vlad’s post goes over the original idea, propellant, shells, and some of the arming ideas we have come up with.  In this forum, we’re going to do a post about the electronics, cameras, battery packs, etc.

But go read Vlad’s post.  He has GREAT details about the components and ideas!

Oh, and for the video of our first launch, go here.  http://www.youtube.com/user/quadling1#p/a/u/0/u0OZ45EvO8o

Only the first minute or so is useful, but we left the whole thing there so you can watch our failure drills.  ;)

37mm Camera Launcher

Vlad Gostom (@recompiler) and I (@quadling) spent a few weekends to burn parachutes, make the magic smoke come out of cameras, and dress up in enough tactical gear to choke a horse.  What did we accomplish?

A beginning.  We wanted to throw a camera that could push live video to receivers on the ground.  And we wanted to use a 37mm flare launcher to do the pushing.  Well, Vlad owns a launcher from Spike’s Tactical.  (Awesome people at Spike’s, by the way.  Their products rock, and their customer service is fantastic. We do not work for Spike’s.  We just like their stuff.)

Josh owns enough cameras to outfit a small Indian casino.  No, seriously.  So let’s try putting it together.

We managed to find small wireless cameras that would fit in Baby Soda Bottles (or Parison Tubes, for the pedantic).  Battery adapters were hand made, and hand wired.  Soldering lithium-ion batteries was fun, in a fatalistic way. Hey, you heat up something that burns, enthusiastically, and not be fatalistic!

Custom shells were acquired, ballistic tables calculated, and primers bought.  It’s time. Drumroll!

Well, it was an abject failure.  But a great success all at the same time.  The projectile only flew about 30 feet.  The video was not-so-good.  But it flew.  It worked.  We’ve got a lot of work ahead of us, but Vlad and I are convinced it’s workable.

So we presented on the matter at BsidesLV and Defcon.  Why would you present a firearm talk at a Hacker Con?  Ah!  Well, we’re hackers.  And the informational aspects of this make this a tool of Cyber war, or Ground Search and Rescue Info.

Um, people listened. Wow!

Couple things.  The photo in many of the stories is of me.  (Dear god)  Oleg Volk took the photo.  Oleg is a friend of ours, and a truly awesome photographer.  If you get a chance, please check out his site.  Olegvolk.net

There are many things unsaid in the articles.  Slashdot has some great questions and comments.  I’ve answered some, and I’ll answer any here too.

For now, I have a Blue Man Group show to go to, since we’re still in Vegas.  Talk to you a little later tonight!

Joshua

Edit: Looks like we made GeeksAreSexy!  Yes!

Also, we made a website called Sync, albeit with a few details wrong. We are aiming for 3-400 meters in the air, not 75, but hey, thanks for checking us out anyway!

First Time Trap Shooting With A 20 Gauge

Thanks to my brother I got to go trap shooting for the very first time with his Berreta 20 gauge semi-automatic shotgun at a great shooting club in upstate New York while he demoed our guide’s similar 12 gauge. We had a great trainer for three hours guiding us through different scenarios and flight patterns in multiple settings from open meadow to woodland. But for a “warmup” we actually first went to the rifle range to try out my brother’s .270 bolt action deer rifle. I was not ready for that! I figured, okay, you’re a hunter, in the woods… everything is stealthy and quiet. Man, this rifle had a bark! You might be laughing, but I had never been near a high powered rifle before this. After my brother fired it a few times it was my turn. Even with it resting on a sandbag I thought it was going to jump back and hit me in the face. I still manage to get a good three shot grouping at 75 yards and to hit a round metal kill zone target at 100 yards on my first try. I still wasn’t used to the bark, but now had some basic confidence in moving on to our shotgun lessons.

The first trap scenario was a slight gully in front of us with a hill sloping up showing sky behind with trees on either side. This trap shot the clay straight up and I was told to lead slightly ahead and shot just as it started to slow before the height of its trajectory.

The next one was looking up a cleared hillside with heavy woods left and right. For this one we had to shot twice. The first clay winged out quickly close by from my right and flew away up the hill almost immediately followed by a second clay further out on the left crossing to the right about half way up the hill with maybe just a two or three seconds between shots. That was quite a challenge!

Our third scenario was an open field with lots of sky, with the sun in our eyes on the left shooting at a clay traveling to the right and at a quickly rising clay on the right making a slight arch to the left.

All in all it was a great morning and I even got two compliments from our guide. A great experience that encouraged me to continue, and with the 20 gauge, very little punishment. I was just a little bit sore the next day, but pleasantly so, if you know what I mean, but ready to go for my first day hunting with a shotgun! I’ll save that story for my next post.
