The first thing I did when I got my Arduino Duemilanove from Hacktronics was of course open the box. Inside was the Arduino, a solderless breadboard, five 270 ohm resistors, six LED’s in assorted colors, a micro pushbutton switch, an assortment of colored jumpers, a USB cable, and a bubblegum flavored dum-dum ($50 delivered). I …
Interfacing a Arduino to your car or truck computer allows you to monitor the performance of your vehicle and watch for and explain trouble codes. You could build your own custom gauge display, monitor fuel consumption, turbo boost pressures and more. There’s a bit of interfacing to do, but there is a chip that talks …
Need to control a pneumatic cylinder? We use low voltage compressed air cylinders at work, and that gave me the idea for some cool steampunk style pneumatic controls. The Arduino can use a relay to activate the solenoid on the compressed air cylinder, extending the cylinder and retracting it. This could be used to open …
One of my goals for the weather station and energy monitor is to be able to access it remotely. The best way I figure is the universal front end, a web browser. this requires me to interface a ethernet interface, web server software, and logging cabaility to my microprocessor applications. Well, the hardware already exists, …
Although this project is for a firewood processor, it would work similarly for a diesel generator. A Arduino processor controls a servo connected to the throttle linkage. Run the VW (or Mercedes, Kubota, etc.) Diesel engine on used filtered vegetable oil, and you have almost free electricity. Belt drive a 1800 rpm alternator off the …
One of our planned projects is a home weather station. We have looked at various temperature, humidity, and barometric pressure sensors. I have been considering how to make a self emptying rain sensor, and wind speed and direction sensor (important for siting wind turbines), as well as a solar insolation detector. Well, a lot of …
