Control your garage door from the internet, inside your home, from your car. This project permits you to control see the status of your garage door and open or close it from:
The schematics, pc board layout, firmware, case, instructions are given in the description.
Here is a project that allow your laptop to connect to the Autostar wirelessly. Yes without wires. This project is a bit complicated to build and may require a small expertise in serial communication but with a little help, anyone can build it. I've provided the schematic and the code. The cost is only about $60, and includes all the components necessary. Why not take a look.
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.
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.
