This is an update to my previously-built Logitech 4000 SC1 modification in 2011. Note that the modification was originally designed to work with Parallel ports. Since such ports are now obsolete, changes to the circuitry have been implemented to allow the modified camera to be connected to newer laptops via USB ports (by using a USB-to-Serial Port adapter).
It is strongly recommended that you read the article about the previous version of this camera (link provided above) along with the comments left by the readers as this will give you a brief background as to why this update is necessary. A lot of details in this page will not make sense to you if you are not familiar with the history of the project.
WARNING: I assume no responsibility for any damage caused to your camera/equipment by following the information presented here. Keep in mind that success cannot be guaranteed even if you have followed the instructions exactly as described. This modification must be attempted only with those who are comfortable working with electric circuits. Proceed with caution and follow instructions at your own risk.
