Digital Camera Integration Presented by: Anna Vigil Electronics Engineering Technology Colorado State University-Pueblo

Radio Shack: FLATFOTO

Specifications Camera:  16MB internal memory  3.0 Megapixel  1.5” color TFT LCD screen Computer requirement:  200MHz Pentium Processor (or faster)  200MB hard disk space

System Modification  Step 1: Remove 5 screws to take off front cover

System Modification  Step 2: Pull down on the black lever to release the ribbon Black Lever Ribbon

System Modification  Step 3: Remove the 3 screws and take of the top circuit board leaving the bottom board attached

System Modification  Step 4: Identify where the trigger is and pull bottom board out. Use a multimeter to show where the continuity is when the button is pressed. You will hear a beep when there is continuity.

System Modification  Step 5: Identify the power button and perform the same continuity test when the button is pressed.

System Modification  Step 6: Solder wires to the contacts with continuity for the power and trigger button. Two wires to each button. Caution: Do Not strip the other end of the wire yet to avoid accidental contacts. Power Trigger

System Modification  Step 7: Remove the power and trigger buttons from the camera in order to feed the wires through.

System Modification : Reassembly All the modifications to the camera are done. Now it’s time to reassemble.  Step 8: Place the bottom circuit board back on feeding the wires from the power button through the hole.  Step 9: Place the other circuit board on top making sure to line up the holes for the three screws.  Step 10: Connect the ribbon and lock it with the black lever.  Step 11: Place the front cover on making sure to feed the trigger wires through the top hole. Place all screws back in.

Camera Integration  DC voltage cannot be put to the camera directly so relays must be used.  Connect your power and trigger wires to the C and NO terminals on the relay.  If a PIC microcontroller is going to be used to drive the relays, they do not put out enough current to drive the relay, therefore, a transistor buffer must be used.  Make sure to put a diode between the coil and the transistor circuit to protect the coil.
