???Controlling The World???: Part 1, is a grade 10 interface project involving several units of the TEE20 curriculum. It could be used as a final or summative project. It includes designing and making an interface device (designing a circuit, making a circuit board {etching/routing}, making a ???D??? shell connector for connecting to a parallel port, soldering components to the board, programming to control the device through the parallel port and reporting on the results. It is possible to do this project a number of different ways (including no etching, little or no soldering) but the resources required for the version provided here include: copper board (and a means to either etch or CNC router it), 8 to 16 LEDs (5 mm recommended, one or two per data line), 240 to 300 ohm resistors (100 ohm if you are running 2 LEDs on a line), 9 solid core wires (small guage, 12 to 16 inches in length, old Cat 5 network cables are perfect), D-sub/D-shell 25 pin connector (any electronics shop), 9 pins for the D-shell connector (for connecting the 9 wires to it, electronics shop), a crimping tool for crimping the pins onto the wires and then a computer with programming software on it that will let you control the data lines of the parallel port. There are resources, a rubric and an evaluation list that help students find their way through the project.Students (Instructional Materials)Turing
