The document summarizes a student's work on a computer controlled dobby weaving machine project. The student modified an existing code to control DC motors to lift harnesses up and down on a weaving machine. Testing showed the motors needed more power than initially used. The student plans to continue working on the project to control 16 harnesses and develop an interface and documentation for users. Future goals include different machine sizes and complexity as well as sample patterns.

1. The first project I started working on was COMPUTER CONTROLLED DOBBY MACHINE. Normally dobby machine being one which has many harnesses (4-16) and which enables the user to make different patterns on the fabric by varying the pattern of the harness lifting and the weft. Electronic Dobby-Loom

3. What to make with the Machine Varieties of designs….

5. The Machine Construction Basic Motion I modified Neil's code for DC motor control using an H-bridge so that it will suit the time and span of the harness lifting. You can see the short video how the motion of the ROTATION of the DC motor could be mapped to the UP and DOWN movement of the Harness.
