Convert Carousels of 35mm Slides to Digital Images/Pictures

An automated, do-it-yourself setup using a digital camera

Slide Conversion Control Box

ClickSlideRelaysWhy a Control Box?

To make the system automated, the control box provides a bridge between the computer, the carousel project, and the camera. For each slide, the control box triggers the carousel to move one step forward, then focus the camera, then take the picture. The process repeats until the carousel is fully converted.
The green USB Relay Module has been updated by Numato to the red Module shown below.

Control Box Materials:

  • Box from Radio Shack - 2 1/4" x 4" x 6"
  • Numato 4 Channel USB Relay Module
  • 4 each - 6/32 flathead machine screws, 4 nuts, and 4 standoffs
  • 2.5mm jack for camera cable - Radio Shack #274-245 (mounts in box)
  • 4-pin cable jack - Radio Shack # 274-002 (mounts in box)
  • 4-pin female plug - Radio Shack #274-001 (The 4-pin jack and plug replace the remote-control-end of the carousel's remote control cable. The carousel-end of the remote control (5-pin) is left unchanged.)
  • 12V DC 100mA power supply

The USB Relay Module is mounted within the box so that the USB connector is flush against the inside wall of the box. The remaining wires are connected as shown in the schematic on the right. Refer to the USB Relay Module Manual for more information.
The connections shown on the right-hand edge of this schematic are on the relay module itself. The connections shown on the left-hand side of the schematic connect to external devices (projector, camera, and 12V DC 100mA power supply). {The schematic for the Camera socket to the USB Relay Module was edited 12-22-2011.}
The color codes shown on the right side of the schematic are for the wire selected to use inside the box (conductors from a Cat-5 cable). The wiring colors internal to the box are not important.
However, The colors shown on the projector cable are very important and you can use these colors to ensure you have connected the correct remote control lines to the relay module ports (SW0 through SW3).

Pinout for Kodak Carousel Remote Control Connector

For reference, the detailed connections for the carousel remote control jack are shown here.

The camera remote wiring may need to be customized depending upon your specific camera. Here is the wiring used for the Canon EOS Rebel. Normally, a partial push of the camera remote begins the auto-focus process, and a full push of the camera remote triggers the shutter.

This cable and connector is a standard 2.5 mm cable that is used for cell phone and cordless headsets.

Before You Connect the Box to Your Computer

Once your box is built, wait until the ClickSlide software (see below) is installed before connecting the box to your computer with a USB printer cable. You will need a driver that this software provides to make sure the box works properly.

ClickSlide LogoClickSlide Software Installation

The ClickSlide software is used to coordinate the carousel and camera operation during conversion. This software is available as a free download (Approx. 100 MB). This is a very large download and will work best with a high-speed internet connection.

To download and install the ClickSlide software, click this link and choose "Run", or choose "Save As…" and then run the self-extracting executable after it has downloaded. Choose all of the default installation options and the software will install to your computer.

The first time you connect your control box to your computer, it will prompt you for a driver. This driver will be located on your desktop in a folder called "ClickSlide Driver". Use the Device Manager in Windows (or choose "Have Disk...") during the device driver installation process to point to this folder.

Once the driver is installed, you can delete this desktop item containing the driver.
