I have lots of different home-made plexiglass shapes but always seem to be drawn to the plain rectangular shape or the hoop. I have been taking a couple of small shapes out with me recently as they fit in with all my other gear but have not been inspired to paint with them as I find it takes a lot of concentration and time to create something I'm happy with. So drawing on inspiration from my LP friends, I set up my trusty circuit board and fixed the small "flame" plexi shape to a wheel attached to a tripod and using the Ryu's Lightworks V2 torch and my SonyA7iii mounted on a rotation gimbal, I rotated the flashing blade and capped between each of the 8 points of rotation using a Samyang 14mm lens. This had been preceded by a shot of the circuit board using a Minolta MD 50mm f1.7 with macro extension tubes, then lens capped and swapped mid-exposure for the Samyang. Chuffed at the 1 successful attempt. Packed up and a cup of tea.

A magic collection of old radios from the 1920s to the 1960s.
Well worth a visit. Just check when they are open before calling.
My favorite compact, Olympus 35RC, all ready for action: small, light strap for hanging on shoulder, vented lens hood (uneccessary but fun) and wide angle finder (absolutely unecessary but fun).
I just can't say how nice it is to shoot with an RC -- I actually agree with Ken Rockwell that in many functional ways, this camera is better than a Leica.

Produced between 1956 and 1965 by Chicago based Imperial Camera Corp, Imperial Savoy was one of the first 6×6 cameras they produced under the Imperial name. It takes a 620 roll film, giving 12 6×6 exposures. 620 film is pretty much identical to 120 film with the exception that the spool it’s wound around has thinner ends, making the roll of film shorter.

Finally the high-speed laser camera is ready.
What's new in this version?
- I currently use one of the fastest shutters available. The shutter-lag is only 3.3 msec. This is the time from the command to the moment the picture is taken. The internal Nikon D300 shutter-lag is normal arround 52 msec, a lot to slow for in-flight insects at closeup distance.
The used external shutter is the Uniblitz VS14 shutter. I used the naked body shutter, so the housing is a DIY version. The external shutter is now between the camera and the lens. This DIY housing is only 30mm wide. Because this shutter work as a macro ring, the infinit focus range is limited. But in my case the usable range goes from 17mm to 82 mm frame picture. This range is super ideal for small insects in-flight.
I use now 3 flashes, 2 x SB-80-DX and one ringflash the SB-29-S. This must result into better lighting. The ringflash is not connected to the macrolens but via a new DIY adapter to the frame. This results into a fix position as the macrolens lenght change with the macro setting. If this ringflash stay on the lens, the laser detection optics have not enough free to see the reflected IR signals.
In this version the lasers are a lot more accessible to adjust them correct at the ideal focuspoint of the camera. The results of this is a very high sensivity of the detector system, even at very closeup and high speed movements of the insects. The laser detection time is now 2x 60 usec or 120 usec, the shutter-lag is 3.3 msec, so I have set the flash delay at 3.5 msec to have a small save intervall.
The used photo detector diode is now the BPW41N. The detector have a integrated narrow filter. This filter is used together with IR lasers at 980 nm. The result is insensitive to the sunlight, one of the bigggest problem previous years. The new IR lasers are now very fast switching lasers and the power is a little higher, this results also into a higher reflected signal for the photodiode. results are smaller insects can be detected at higher speed.
The electronics are total reworked. The basic module is again the Terasic CPLD board (MAX II). The high voltage driver for the external shutter is adjusted to this new timings and extra signal are now avaible to open the external shutter during the adjusting procedure of the camera. The diafragma are now set manual on the AF105/2.8Dmicro lens because the camera c'nt drive this as the external shutter is now between lens and camera.
A lot of extra switches are now avaible for new functions. One of this function are the TTL power drive of the flashes via an external 6 position switch on the frame. A second switch set the ballans between the left and the right side into 6 positions. All this information is displayed on the LCD display.
All connection are now a lot reliable. The hole frame contains the electronic prints and all the connection cables. Extra highpower leds are avaible to work at night. This leds are powered via 4 external AA batterys so they give no extra load to the central power batterys (6xAA) for the hole controller.
Total weight is now 7.2 kg. The ringflash have added here an extra load but I exect significant improvement for closeup shots where the distance from object to the front of the macro lens is only 105mm for a macro setting of 2.2:1 (17mm real live picture projection on the sensor).
This setup is really complex but I have chosen for optimum speed and performance. This Uniblitz VS14 shutter is one of the fastest version on the market that supports this integration.
There are a lot of details not to seen on the pictures like how the macrolens focus ring can be locked. Even on manual position, the lens can move slow out focus in long time. So I have loked the focus ring once the calibration is finish.
The hit rate of this camera system is near 100%. Only correct pictures are taken in full flight. This 3.5 msec shutter-lag guarantees a short movement of the insects between detection and the time that the picture are taken. The relative speed at closeup distance of fast moving insects are extreeme high. A normal camera show always a insects out the frame with the internal shutter-lag.
I have worked near 4 months on this design. The total cost is high. I have to buy a lot of new tools for the lathe and the miller machine. New lasers, tested multiple photodiodes, find the necessary aluminum parts, a lot of electronic components etc.. But now I'm ready to capture the beautiful insects once they commeback in spring.

Not only did this Kmart hold onto it's electronics desk, it still had key-making facilities (or more correctly, a little key-making machine) as well! I never saw anyone at this counter for the duration of our visit though.

K is for Keys, and Keyboard.
A picture of my keyboard for K seemed quite appropriate as I seem to be spending a lot of time in-front of it lately.
I shot this in manual mode with an aperture of f/3.6 for 1/5sec the shot is lit with natural light from the window.

Yet another view here that could very well have been from the old Southaven TM location. There were quite a few more electronics items in this store, as compared to the newer Southaven location.

La Mat-124 G es una cámara de origen japonés fabricada por Yashica entre 1970 y 1986. Se trata del último de los modelos TLR producidos por la marca. Fue una cámara que gozo de gran aceptación, y pese a que se trataba de un modelo que “a priori” podía parecer obsoleto, su aparición enel mercado fue un verdadero acierto de la factoria nipona.
Esta TLR permite trabajar con película de 120 o 220 mm. Entre sus principales características podemos destacar las siguientes:
- Objetivo formado por cuatro elementos marca “Yashimon” de 80 mm., con una apertura máxima de f/3,5 y mínima de f/22.
- Obturador “copal” que ofrece velocidades que van desde 1 seg. a 1/500 seg., además de un modo B (Bulb).
- Un sistema de enfoque basado en los siguientes elementos: una pantalla de vidrio esmerilado que se emplea cuando se enfoca a nivel de la cintura, una lupa de 3x dioptrías para el enfoque crítico y un visor deportivo empleado para el enfoque de objetos en movimiento a nivel del ojo.
- Un exposímetro de tipo CdS de aguja apto para sensibilidades 25 y 400 ASA con el interruptor acoplado en del visor. Este funciona con una pila de mercurio de 1,3 v, aunque responde igualmente con una pila alcalina de 1,5 v. (tipo pila 625A RL9 de 1,5 v.)
La velocidad de obturación y el diafragma se seleccionan mediante dos ruedas situadas en la placa frontal y los valores seleccionados aparecen en una ventanita situada encima de la lente de encuadre, de modo que mirando hacia la pantalla de enfoque en el visor de cintura, ambos valores, así como las indicaciones del exposímetro se ven cómodamente.
El enfoque se efectúa mediante una rueda de enfoque situada en el lateral izquierdo de la cámara. Tiene una escala de distancia rodeada de una escala de profundidad de campo grabada en el cuerpo de la cámara. También hay una pequeña ventana donde poner la sensibilidad de la película, tipo de film, velocidad de obturación y diafragma.
El cuerpo es completamente metálico recubierto de semipiel. Es una cámara pesada, alrededor de 1,1 kg. El arrastre de la película y el armado del obturador se realizan mediante una palanca, cuyo movimiento es bastante ruidoso.
Se ha dicho de ella que se trata de una copia de “gran calidad” de la Rolleiflex por lo que los controles tienen una configuración similar y alguno de los accesorios (filtros, parasoles, etc. ) comparten con esta la montura Bay 1.
