Matchbook - A tiny book format

i was reading an interesting article that articulated something i've thought of for a while - so many good ideas and stories out there... how to stand out?

Infestation (the article)

Unless you are famous, you won't be seen outside your normal circles.  I'm ok with this but do like the broader feedback.  Not interested in the fame or fortune, just want input on my thoughts or ideas.  Kind of why i blog to myself...

here is a fun project.  A mini book, the size of a book of matches.  "Matchbook".

it is simply an ATtiny85 microcontroller (~$1USD), a SEEPROM memory device (i have lots of the Microchip 24LC256 already), and a cheap 1" OLED display.  Everything fits the form-factor EXCEPT the battery... gotta work on that.  No good having a mini book with a cord or power needs.  The memory gives space for ~20k ascii text files, and is pushed in by an Arduino over the USB.

My first preferences for Matchbook titles:

The Machine Stops (E M Forster)

The Feeling of Power (Isaac Asmov)

Great short stories, and 'relevant' to the form itself.

Dark Light Shooting

OK, its been a while since posting, and this isn't anything new but needed for another project.

We are doing some night drills with the kids home from college, and using our wifi-controlled targets.  They are really fun, and i've added a 'random' feature to turn the target on/off for random lengths of time. 

Here are some of the logo images...

you can get the targets and more info at shootdarklight@gmail.com.

where has the time gone...

Wildlife as viewed by Thermal Camera

Here are some comparison videos showing a raccoon and some deer moving through the trees.

The raccoon was about 25 yards away and tough to see even with a flashlight in the early morning.  Lit up the thermal camera, though.

I never saw the deer until i put up the thermal camera and there were some bright red spots.  About 40 yards away as they moved off slowly through the trees.

Thermal Camera and Suppressors

Yep, more thermal camera pictures.  Here are some of the weapons we took pictures of after heating up the cans.

Warning, plenty of targets were harmed in the making of these images.

Here's video of a 22LR:

a Glock 17 (Liberty can):

Knife Making and Forge with the Thermal Camera

Yeah, we are pointing the thermal camera at about everything these days.  Technology lets us see the hidden world.

We did a comparison of quenching tool steel in water vs. motor oil.  i was quite suprised how quickly the oil heated up and how slowly it cooled the steel.  impressive.

Here is a better comparison of the two.

Thermal Camera Video for Target Practice

This thermal camera (Seek CompactXR) we are playing with for Drone use is also a ton of fun out shooting.  Shooting is fun anyway, so we took a bunch of video.

Here's snapshot of a 50 BMG (BMG = BigMammaGun!).  Before the shot...

During the shot...

After the Shot.  Barrel didn't really heat up as much as i expected.  that hot forehead caught the camera's attention, though.

Here's one of the videos.  more on the FaceTube channel.

The suppressors were great fun, too.  22LR really didn't heat up much.  Here is a Liberty Suppressor on a Glock 17.  165*F is the hottest the camera recorded.

Here's one of the videos.

An AR chambered in 7.62x39.  Love this gun!  The pucker factor is great - LOUD, belching flame, and throwing a 30cal projectile.  Gets everyone's attention quick!

Here is a lever action 357 (Ruger) with the suppressor on it.  We were only shooting 38s, so it was quiet, cool, and almost boring.  almost...

Lots of video on the FaceTube channel.

Thermal Camera for DJI Phantom 3

Working on a thermal camera to see through the trees and locate stray cows...

No pictures yet on the design, but the test flights are AWESOME!

here is some early test video... i'll try to upload more later, but we hare having too much fun lately.

Those stray cows don't stand a chance hiding from us...

Laser Attachment for DJI Phantom 3

We are now shipping a laser attachment for the DJI Phantom 3 (Advanced) with the 4K camera. 

The package includes a custom, 3D printed camera attachment with two (2) laser diodes, a battery holder / gimbel protector, protective case, and a rechargeable CR123a battery.  The lasers point where the Phantom 3's camera is pointing.  The laser attachment glows-in-the-dark for easier handling in low-light or dark conditions.

2 different models - one where the lasers are always on, and last up to 1 hour on a single charge of the CR123a battery.  

On the 2nd model, you can remotely turn the lasers ON or OFF using the DJI Go App.  Easy Peasy!

 The laser attachment glows in the dark.

Here is the total assembly.  It weighs 1.2 ounces, so is light, balanced, and easy for the drone to carry.  The attachment on the camera is ~0.2 ounces, and does NOT inhibit the camera or gimbel in any way.

Drone with a Knife!

Just kidding.  Not a drone post!  Some cool knives one of the boys has been making lately.  We have a separate blog to show them, and even some video HERE

The blog is http://yukonapproved.blogspot.com/

Drone Range Finder

Yep, another drone post.  There will be many more...

Out shooting the other day, we used the drone to not only range the distance but to give feedback on where we were hitting.  It was great!  The range was much farther than we guestimated, and with the drone overhead we could see where the bullet strikes were and quickly compensate.  We are taking the bird every time now!

The distance to the target was ~1858 feet.  The argument was wither it was 450 or 550 yards away... we were both wrong!

In the image above, we could see (real-time) the bullets hitting at the base of the right leg of the target.  Having a larger tablet to fly the drone is a BIG deal here, to see better where the strikes are.  My old eyes could barely make it out on the phone we were using.  A quick adjustment was ready.

Here is a view from above the shooter.  Target is at the base of the taller trees, to the right of them.  You might even recognize the spot...

No real good video to show what we were seeing... but here is from a different time when the drone could show us steel strikes.

A Drone with Freakin' Lasers

It didn't take long flying our drone before we started thinking of fun things to do and add to it.  How about Freakin' LAZERS!

We had some caps 3D printed to fit and stay in place on several different drone cameras.  The plastic they are printed with is Glow-in-the-dark!  Of course, just having lasers wasn't enough - we wanted to remote control them, on-n-off, while flying.  The easiest way to do this is using the remote control's ability to turn the drone's LEDs on-n-off.  That way we get a farther range on the control.

Under settings, a simple switch turns them on for us.  easy peasy.

Two lasers are added, and the whole thing, including battery (rechargable) is under 1 oz.

 The tolerances on the 3D print weren't good... but some slight modifications were all that was needed.  for the Phantom 3's 4K camera, we also cut down the length of the cap to be less obtrusive.  There are tabs for a rubber band to secure the cap to the back of the camera, but with the radial force exerted by the cap itself, it stays in place very well.

Everything is installed quickly so we don't have it permanently on the drone.  One mod we did make to the drone was to drill into the LED cap and hot-glue the light sensor directly to the bird.  We are using this sensor for other control projects, and it is easy to attach to the laser's control when we put the cap on.  You can see how we secured the sensor's wire to the drone's leg to keep it in place, and keep the wires from flapping about.

If you are interested in buying a cap or a whole setup, shoot us an email!  we've made a few of them and can make more.

Some demo videos:

A Drone for Exploring

Finally got one, and now that we have it, I wish we had gotten one sooner!  This thing is so fun, so easy to fly, and really expands many options in exploring the world.

One favorite has been to fly around all the large ships and fishing going on along the big river.  It is a bit freaky flying so far over the water... but worth it.

With an app showing what ships are passing by, we can run down and fly about them.

 Here is the Queen of the West from the air.

You can see video of her (and other big ships) here: https://www.youtube.com/watch?v=Qln8n87UlxY

Night flying is also tricky, and unnerving.  Be sure to scout out all the power-lines and trees before going back at night!   Here's a rodeo practice going on at the Fairgrounds.

here is a race at the local race track.

So much fun.  All the new features and capabilities make this really easy to pick up and fly.  The 4K camera is especially awesome!

Stay tuned for some of the other modifications and projects...

One Big Bullet

Biggest one I've seen in the wild, anyway.  While hunting firewood for cooking my fish along the bank of the Sea of Galilee i found this dude.  I was only about 300 yards from the entrance to Capernaum on the northwest side.  In the rocks, and seemed to have been there a while.

For reference, that is a size 15 shoe.

Looking East toward the Golan.

From the looks of it, could have come from any number of old tanks still in the area from '67.

I may take it back to see if it will 'fit' any of the memorials that are around, or the Armour out in the pastures.

 Visiting with a friend who served on a tank crew in 1972, he said it was an AP Tracer round.  He wasn't sure if there was any explosives inside it as he had never seen one still in a single piece.

A little video.  Any inputs or clarification about the round are appreciated.

Coward Gun Scope Demo

This is a fun project in the works - a DIY Felin handgun scope.  The small camera is coupled to a laser and transmits its video to ANY smartphone or tablet... allowing the user to shoot around corners or cover without exposing any personal area.  Look and shoot in relative safety - hence the name "Coward Scope".

Pretty simple, and WAY cheaper than any commercial products out there.  Simple, uncomplicated, and disposable!

Here is an example of a commercial product...

We posted about the details of the camera already.

Did i mention cheap and disposable?  The camera itself is less than the cost of a cheap box of 9mm!

Here are some videos if the prototype in action.

Here is video off of the smartphone
