Bat Detector Box, this box is used to detect the presence of bats by converting their echolocation ultrasound signals to audible frequencies usually about 300 Hz to 5 kHz. Bats emit calls from about 12 kHz to 160 kHz, but the upper frequencies in this range are rapidly absorbed in air. Bats use echolocation which is the use of sound waves and echoes to determine where objects are in space, bats send out sound waves from their mouth or nose. When the sound waves hit an object they produce echoes. So when it gets a bit warmer I will be out there listening for them, And Pauline if you see this I still have your bat box and it’s still ok thanks.
117 Pictures in 2017 – 14 Radio Day
I rearranged my little watercolor box. But after finishing this drawing I squashed in one more pan. ;-)

Teasing is over, here is the real thing. Inside the box, a semi-illuminated street with a strange scene going on.
These photos are'nt so great, but this creation means a lot to me, so please visit this page for more pix, different views and construction details :))
Made for a local convention this last week-end, and more coming up hopefully!
Feel free to tell me what you think, good or bad, or anything in between!
cheers y'all :D
This photo, suggestive of an old-fashioned lift cage, in fact shows inside a much smaller enclosure: one of the electrode housing boxes that will fly on ESA’s LISA Pathfinder mission, planned for launch later this year. The inside of the box measures 5.5 cm on each side.
LISA Pathfinder is a technology demonstrator that will pave the way for future space-based observatories measuring gravitational waves – ripples in the fabric of space-time that are predicted by Albert Einstein’s general theory of relativity. Produced by massive accelerating bodies, these perturbations are expected to be abundant across the Universe, but they are yet to be detected directly.
Although not aiming at detecting gravitational waves, LISA Pathfinder will test the technologies that could be used for this daunting endeavour. In particular, the mission’s goal is to achieve the best free-fall ever, reducing all the non-gravitational forces acting on two test masses and controlling any residual effect with unprecedented accuracy.
LISA Pathfinder's test masses are two identical cubes of solid gold–platinum alloy, measuring 4.6 cm on a side and almost 2 kg each. Once in space, they will have no mechanical contact with their immediate environment. Each cube is surrounded by an ‘electrode housing’, its walls lying several millimetres from the cube on all six sides.
The boxes will track the positions of the test masses and apply tiny adjustments if needed. The housings are part of highly sophisticated equipment that includes a laser metrology system and several microthrusters to apply small shifts to the spacecraft’s position to keep it centred on the masses.
In fact, achieving a near-perfect gravitational free fall is very complex even in space, as forces other than gravity will disturb the motion of the cubes, including pressure from sunlight and particles from the solar wind.
The data collected by LISA Pathfinder will reveal all the spurious effects that can affect the purely gravitational motion of two test masses in space. In a full-scale gravitational wave observatory, the test masses would be contained in individual spacecraft separated by a million kilometres. Knowledge of all the non-gravitational forces acting on them will be needed to calibrate and optimise such a future experiment, enabling the detection of possible variations in the position of the test masses caused by a passing gravitational wave.

8" tiffany box cake covered in fondant. fondant covered foam lid. ring is edible but diamond is glass.
This little gold and silver gift box is only 3 cm and actually has a small clock and picture frame inside.
As I sat waiting for the mountain bluebirds to return to their nesting box my shutter finger got itchy to take some pics... so I decided to play with an HDR shot...

They say the eye is the Window of the soul. Here it's a reflection of a Woman with a camera :)
The Common Box Turtle isn't as common today as it once was. This species is terrestrial. Habitat loss and fragmentation has resulted in it being considered a species of concern in Ohio. Many have been killed by vehicles while crossing roadways. Decades ago I might see two dozen of these turtles in a single day. Now I'm lucky if I see one every year or two.
When what was on the box, was literally in a box.
Another scene and glimpse into "Hole House Farm" marvellous decay and a plethora of old things in large numbers and in some quarters haphazardly piled up.
The best thing about running out of light, a reason to go back!
The Florida box turtle has a narrow and highly domed shell. Its carapace has a distinct pattern of yellow stripes that make it easily identifiable. This turtle has sharp claws as well as a sharp beak used for catching small insects and eating fruits, vegetables, and fungi.
