SliderPro 200


Price includes US shipping.

The three components of the SliderPro 200 can be used with your digital camera and your Kodak slide projector to automatically make digital copies of a tray full of slides completely unattended. Some additional electrical connections must be made to the camera and projector.

By removing your projector's lens (it pulls right out) and aiming your camera into the empty lens tube, a photo can be taken of a slide. The projector can advance through a tray of slides and the camera can take a high quality photo of each one. 

Any digital camera can make copies of slides, but a sensor with about 14MP is required to capture all of the information in 35 mm film. To fill the frame with the slide image while the slide is inside the projector, a macro lens with a focal length of about 120 to 200 mm (35 mm equivalent, or 80 to 120 mm for an APS-C sensor) is required. Extension tubes can also work for non-macro lenses.


With some Kodak projectors that allow the lamp housing to be removed, the SliderLamp slides in to replace the old housing. The old lamp housing can be saved unharmed to be used at any time. The SliderLamp includes a 2.5 watt LED lamp with its own power supply and three integrated diffusers to produce an even illumination with no vignetting. 

The SliderLamp has been tested with a Kodak Carousel 4600 and 5600 projectors and should work with other models in the 4000 and 5000 series. It should also work with Ektagraphic III projectors but has not been tested with them. It does not work with some Ektagraphic projectors other than the Ektagraphic III or with Carousel model numbers lower than 1000. Check the figure in the gallery above to see if it will fit in your projector.

If the SliderLamp does not fit in your projector (e.g., model numbers below 1000), the LED lamp and diffusers can be used to modify your projector's lamp system to accomplish the same result. Some novel modding is required.


Most digital SLRs and mirrorless cameras can be mounted solidly on the SliderPlate. The included tripod screw holds the camera securely at the level of the projector so the camera lens can point into, and along the optical axis of, the projector's empty lens tube (set the projector lens in a safe place for later use). Four leveling legs with non-slip feet allow the camera to be leveled while providing a stable base.


The SliderSwitcher can be used to automate slide copying. It is an Arduino Nano (ATmega 168) and two relays which can repeatedly send signals to the projector to advance to the next slide and then trigger the camera's shutter. The Arduino is pre-programmed to operate the relays, but you must make the electronic connections to the projector and camera. 

The connection to the projector can be made with the projector's standard wired remote control. A non-destructive modification must be made to the remote so the relay completes the circuit that normally would be completed by pressing a button. Similarly, a wired remote (or just the remote cable) for the camera can be connected so the relay completes the circuit that normally would be completed by pressing a button on the remote.

Connecting the SliderSwitcher is optional. The camera can be triggered and the projector advanced manually to make high quality digital copies.

The SliderSwitcher can be easily reprogrammed to copy any number of slides, to work faster or slower, or to take multiple (e.g., bracketed) exposures of each slide. The Arduino sketch loaded onto the Arduino Nano is here:
