Tripod holder for camera

Thir is a camera tripod converter fir the Samsun Galaxy Note 2 phone.  You can record in 1080p on a tripod with it

Photometrics Coolsnap cameras

One camera is a coolsnap K4, which is a 2048 x 2048 x 12 bit cooled camera.

Second camera is a coolsnap camera, color, 1024 x 765 x 12 bit color.

the color camera can be read out with raw bayer array, or read out by a program that combines the array into a color snap.

Many thanks to my friend Dan Goldstein for the K4 camera.

test images will be found here.

Two test lenses were used with the photos.  The wide field one is shot with a Bell & Howell / Angineaux 10mm flat field short focus 16mm camera lens.  The full field lens in the images in these photos are shot with a Sony TV 25mm F1.8 lens.

If you consider the following approximation from cameras:

50mm  "normal" for 35mm format image plane
25mm  "normal for 16mm format image plane  (11m x 6mm)

Coolsnap K4 is 15mm square or a 21mm diagonal format.  However the format of a camera frame is 3 x 4 5 diagonal.  taking the 21mm dimension as the 3 dimension this format is akin to a 25mm diagonal format camera frame.  The normal lens for that would be 17mm.

General info

There are two known versions for the board (chips listed left to right topdown):

	symbios logic 53CF96-2 (narrow SCSI HBA); a pair of Toshiba TC558128AJ-15 (15ns 128Kx8 CMOS static RAM); a pair of ALS245A (buffers); Lattice pLSI1016 (PLCC); LSI KL5C80A16CF (Z80 instruction compatible microcontroller); Atmel AT27C256R-70RC (70ns 32Kx8 CMOS EPROM).
	symbios logic 53CF96-2 (narrow SCSI HBA); a pair of SEC KM681001BJ-15 (15ns 128Kx8 CMOS static RAM); a pair of ALS245A (buffers); LSI KL5C80A16CF (Z80 instruction compatible microcontroller); Atmel AT27C256R-70RC (70ns 32Kx8 CMOS EPROM); Lattice pLSI1016 (PLCC).

The DIP switches

Left to right:

0	dunno
1	dunno
2	dunno
3	SCSI bus termination
4	SCSI bus termination
5	SCSI target bit 2
6	SCSI target bit 1
7	SCSI target bit 0

IDE drive geometry

as far as i can tell the board only understands drives with maximum of 15 heads and 63 sectors per track. the cylinder number is limited to 16384. the controller does not honour the total number of sectors on the drive that limits the total capacity to a little bit less than 8G.
drives with more than 15 heads seem to allow the device to probe but fail to accomplish any actual data transfers resulting in controller timeouts. that sounds like an overflow and thus division by zero on the board's controller (;

English Electric valve thyratron

CX1622S Glass Deuterium Thyatron.  35,000v, 5000A pulses for driving laser tubes or microwave circuits.

These tubes are still used because solid state just doesn't work at these power levels. This is a lower power device.  The real power thyatrons are ceramic and metal container types.

This is a pentode filled with hydrogen gas.  The gas fill allows for quick turnon and turnoff of high current.  In operation this would be the circuit would have a very high magnetic pulsing field (safety warning mentions don't come near it with a pacemaker) and also x-rays.  Out of circuit, don't drop it.

Love large glass objects.
