Here is another fun project. I got it into my head that I wanted a cnc router to help with wooden signs and figures. With a CNC router you can take designs drawn in a CAD program and realize it in wood. The router cuts out the figure drawn in wood and metal, depending on the bit. In order to accomplish this, I had to design and build the router hardware, design and build the stepper motor electronics, and then write the CNC controller software. This page describes how this was (actually is being) done.
Learn about an how we built a ham and weather satellite antenna for about $300.
This project was built from the ground up. The frame was welded from soft steel. The motors are controlled with a circuit originally borrowed but modified from the web. The control board is a standard microcontroller board. and the PC software was written to interface with Satcom available free on the web.
As a fun project we have interfaced a laptop computer to a Mercedes 2007 CLK350. The interface connects to the CAN bus which controls all the audio video controls, as well as the door locks and many other functions. The project uses a commercial CAN bus interface module (a CAN232), the bluetooth firefly and a laptop computer. Take a look at what was accomplished.
A friend of mine wanted to take a picture of a bluebird flying into his backyard. Unfortunately for him, everytime he went outside with his camera, the bluebird flew away. He asked me if it was possible to have a motion detector trigger his camera, which is a Canon 5D. I built this for him. It is a simple project that anyone can make. If you need one it can be had for just a small effort. Check it out.
Computer controlled interface for your CT-17 enabled transceiver or receiver. Works great with the ICOM 706MkII and other ICOM transceivers.
