Implementation of CAN for use in aircraft. The protocol is called CAN-FIX and is a part of the MakerPlane Open Source Airplane project. You can get more information on CAN-FIX here. The idea for this project is to build an Arduino shield that will let it communicate over the CAN bus. I had some Microchip MCP2515 and MCP2551 (CAN Controller and CANTransceiver, respectively)

laying around so I decided to make my own little Arduino shield so that I could quickly try out some ideas. I started with the little ProtoShield that Sparkfun sells. I also had some header material laying around so just getting the PCB without the rest of the kit worked for me. An easier answer may be to get the full ProtoShield Kit. This will give you some buttons and LED`s to play with too. My intention for this particular device is to use it as a generic USB<->CAN converter. Once I have that working, I`ll have a CAN interface for a computer and could use the same code with an Arduino Mini, or something similar, to interface to a Beagleboard, Rasberry Pi or other SBC. The circuit is pretty simple. It`s just an SPI interface to the MCP2515 CAN Controller IC. This IC handles all of the low level details of the CAN protocol. Things like timing, arbitration, error detection etc are all offloaded to this IC. I purposely made mine similar to the CAN Shield that Sparkfun sells. The pins are the same but I choose to use a 20MHz ceramic resonator instead of the 16MHz oscillator that`s on the CAN Shield. The only reason I did that was because I had some. It might make it work better at higher bit rates too but I haven`t tested any of that to know. There are a couple of CAN Shields out there and they all have basically the same interface to the Arduino so this means that we should all be able to use the same software with all of...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
