The xu1541 is the modern way to connect CBM IEC bus devices to todays USB equipped PCs and it is meant to replace the printer port solutions based on the so-called original x1541 cable. The xu1541 interface allows you e.g. to attach a VIC1541 disk drive to your desktop PC as depicted below. This allows for easy transfer of disk images from and to the old units and helps you preserve your ancient data.

This lets you write and read byte values from an sd card. It’s very simple to use. The schematic uses some resistors in a voltage divider to drop down the arduino 5v logic to the sd cards 3v3 logic. So all outgoing signals from the arduino are dropped to 3v3. Incoming signals to the arduino are fine because 3v3 is above logic 1 for arduino. The 3v3 voltage supply from the decimelia was used to supply power to the sd card.

The schematic shows that wiring the LCD to the HEF4094 is a simple operation. It has been drawn in a way that makes possible to develop this as part of a single sided PCB including a variable resistor to control the LCDs contrast. Note that the pinout of the LCD module may differ slightly from the pinout depicted; some LCD modules have pins 15 and 16 on the left side, before pin 1.

The purpose of this project is to show, how you can build a surveillance system with web-page interface. The webcam can be moved vertical or horizontal through the interface, but only in the area that border sensors will allow. The control page is secured with login system, where the user types in an user-name and a password.
On the control page the user can control how the webcam will turn and how many steps it will run. The user can also turn the webcam on and off via web interface. Information about the states will immediately update on the screen. User can also turn the motion detector online, if the camera detects motion, it will automatically save the frames. Naming of the pictures is done with “timestamps”, so it is possible to find out when the picture was taken.
The part that interests me on this project is the servo, because a few years ago i was thinking to something like this, but i never build it. Now it’s nice to see, someone actually build it.
