Philips SPC900NC LX CONVERSION
The following conversions use the modifications developed by William Behrens, Steve Chambers and Martin Burri..
My thanks to them for posting their information for free. Please see terms and conditions of using these modifications on their respective web pages before proceeding with your own camera upgrades.
The conversion shown here is a suggested way but by no means definative and as such is done totally at you own risk and will void your manufactureres warrenty. You have been warned!
I assume you will observe antistatic precautions while converting your camera or else you stand a real chance of zapping it through electrostatic discharge
and it won't work even if you do the conversion right!
Well here it is the latest incarnation of the ToUcam
and with a good grip and a strong pull the lens cover comes off !
Turn it on it's side and use a blade to prise off the side covers, there held on with double sided sticky tape and come off quite easily.
Now press in the clips top & bottom (arrowed), on both sides and prise the two halves apart.
The camera is mounted in a cylinderical holder with two clear 'O' rings around it, remove these.
Now unclip the two halves of the cylinder arrowed on both sides, and prise apart.
The camera is held in with two small screws which you need to remove to get it out.
The image below shows the camera with the USB cable unplugged, the microphone and LED have also been removed.
The camera is spread across two PCB's through a 24 way connector. Unscrew PCB plliar screws and gently split the two boards.
After much thought I decided to limit my LX conversion wiring to the front PCB only.
First remove the lens holder by removing the two small screws on the back of the top CCD board.
I cut the track next and added wires to pin 8 on the CCD for the M.Burri off-amp
mod and also pin 10 of the frame IC, shown below.
Note the lack of glue holding the wires on at this time!
And on the back of the CCD board I cut and added wires for the track from the frame pins 8 & 13.
Now replace the lens holder over the CCD after having made a small exit cutout for the wire from the CCD pin 8 off-amp mod.
Don't forget to clean your finger prints off the CCD before replacing the lens holder!
The notch is arrowed below.
And here it is assembled, note the wire exit.
Next tidy up the control wires, label them up and use a drop of glue to hold them in place.
The two boards were then plugged back together and the LX board stuck to the back of the rear board with doubled sided tape.
This camera was converted for serial operation in this case
After the board was mounted on two plastic pilars as with my ToUcam conversions that are glued to lid of the case on this occasion.
