I have been making armor for a while. Today after putting together some of the scales, I had to test them against impact of a sharp object with high impact. The throwing axes used, weigh 2 pounds 4 ounces, or one Kilogram each. It took a few tries to hit the armor but after I had, I finally managed to break the scales with the tip of the throwing axes.
While the backing used for the impact test does not simulate real impact from a claw, or tooth, it does give a fair idea that it would significantly slow the force of a sharp object trying to pierce what is behind it.
The thread used for this test is a low test weight cotton twine, and held up as well as could be expected for the circumstances.
The velocity of the average throw is about 25 to 30 feet per second (time from thrown axe leaving my hand until impact at target) makes it about 17-24.45 Mph
I am not well versed in physics, but can guess that as the points on the axe are less than 1/4 inch across, with 2 plus pounds of force each behind them divided out between them, there is over a pound of weight hitting the scales. there is little to no give of the backing as it is wood, and each of the rounds weighs about 80 pounds. they did rock back about an inch when they were hit. the blades bit in about 2 inches in the unprotected area, and about 1/4 to one half inch into the armor. Suffice to say, I think this will stop light grazing damage, but will not stop serious point impact. I expect broken bones, or at the least serious bruising from impact, but less probability for large open cuts from a slash.
Later tests with different impacts will be forthcoming, but for the moment, this is the hardest impact testing that would show the worth of what I have been working on.
Further, of the 4 sets of armor made, only one withstood the impact and did not break. it had double layers of scales and the twine holding it snapped on impact. the smaller scales experienced the similar damage with no scales being visibly damaged, but the twine sheered and all the scales flew apart.

Here you see the effect of the different ISO settings of the Panasonic Lumix LX3, the upper crops are jpeg (out of cam) with noise reduction -2. In the middle you can see an ISO 800 image with the same jpeg settings except that nr is +2.
Below you find 2 RAW crops with ISO 800 and 1600.

testing basic movements (just head, arms and hands) using a handmade clay doll that i've just finish doing.
made this short film as a "try-out", looking for improve my stop motion's techniques and use my knowledge to shot advertisement videos in the future.
built a Lady Gaga figure cause she is one of the music icons my class team chose to represent pop music (and because I just love her) :)
she is made of biscuit, clay, play-doh, wire and some recycled material.
unfortunately my camera had just a few shots left, so this first clip is really short.
thanks for watching :)
Jonathon let me test out some of his lighting gear yesterday! Had a lot of fun and learned a lot! Thanks again Jon (he took this shot)!
I am not a very good model btw...well, wasn't trying really...just sitting still. :)
Testing my brand new scanner :)

a quick test of the Nikon 28mm f2.8 on the A7R. I already had a Vivatar 28 with a Canon mount but I had purchased a variable ND filter mount and it was for Nikon. (most of my fast lenses were Nikon before I sold them) I'll use this combo for some long exposure experiments...
Edited SpaceX (probably, although I got this from a NASA source) image of a static test firing of a Falcon 9 rocket. This is the rocket that will carry a man-rated capsule to orbit for testing prior to launching people.
Original caption: At NASA Kennedy Space Center’s Launch Complex 39A, the nine engines of a SpaceX Falcon 9 rocket roar to life in a brief static firing on Jan. 24, 2019. The test was part of checkouts prior to its liftoff for Demo-1, the inaugural flight of one of the spacecraft designed to take NASA astronauts to and from the International Space Station. NASA has worked with SpaceX and Boeing in developing Commercial Crew Program spacecraft to facilitate new human spaceflight systems launching from U.S. soil with the goal of safe, reliable and cost-effective access to low-Earth orbit destinations such as the space station.

I am test-riding this little number. Was surprisingly stable on the highway even on a very windy day. And it kan keep up with the other traffic quite nicely.
This would be the 'sensible' choice for me. Reasonable price, good quality, but no gizmos or 'flash'. It lacks a certain gimme-gimme factor. Hmmmm.
Have to add that the seat is super-comfortable, and the build-quality feels superb.
Testing out my Sony NEX 6 with the e mount 35mm F1.8. This was taken in aperture priority mode F2.0 at ISO 800 with a 1/30 shutter speed. I could have easily backed down to ISO 400 at 1/15 of a second. This shot was taken very quickly and I didn't spend much time composing and dialing in the settings.
