SportLine® Pedometer

Step 1
The first step in this project is to open the Pedometer. For the SportLine® Pedometer there are 3 small Philips head screws on the back of the case. Before you remove them open the battery holder and remove the small watch type battery. Remove the 2 small screws and place them in a container so you don't loose them during the modification. Figure 1 shows this removal.

Step 2
The next step is to locate the solder contact points and solder the wires to them. In this example we used small 30 gauge wire wrap wire we purchased from Radio Shack, but any small gauge wire can be used. Solder a black (ground/common) wire to the spring shown in Figure 2. Next solder a white wire to the counter hammer shown in figure 2. Lastly tape the counter hammer in the up position so that it's not making contact with the spring. Electrical tape works best for this. The last step is to solder the white wire to the white wire of your flash cable, and solder the black wire to the black wire of your flash cable.

Step 3
The last step is to put the pedometer back together by putting the case back on, replacing the screws, and installing the battery. Congratulations, you are done! All you need to do is connect your flash cable to the external light port of your PixContorller board. Every time you trigger the camera the counter will record a count. Note: This only works on PixController PIC chips that support the external light feature, and you must place a piece of electrical tape over the Day/Night sensor so that your external light port is active all the time.
