There's a project I've been tempted to do for a while. When I go kitesurfing I can't take the keys to my VW Transporter into the ocean with me. I've got a small Paxton waterproof RFID tag and a matching reader. (My work pass in my wallet is a Paxton too.) Keyless entry to my van would be fun.

Good.. Common everyone, otherwise Fred gets the kit.

Yeah - come on, guys. I thought I set the bar fairly low. I'd be more than happy to see someone beat me to it with a project that uses more of the Stellaris's capabilities than the CAN and decoding a simple but non-standard serial protocol.

Hi fred and blue hash,

 

Well i have been thinking about a major plan. It involves building a small server out of a arm processor and then attaching a sim module or two to turn it into a telephone switching unit. The unit must receive a remote command, respond availability accept audio feed, and then make a call, and in btw, route the call ie b4 its passed through , so that ads (audio) can be played when the person is in queue.The Oled serves the purpose of being the output for diagnostics and integrate a keyboard port for some basic input.Well this is my idea. if you have any suggestions or link regarding code or hardware resources pls, contact me. And btw this is my entry for this giveaway. Its a really good giveaway to ignore...

Good one.. but kit does not have an audio in., just letting you know :)

Hi Everyone,

 

I've been toying with idea of doing a remote sensing base station, with the aim of monitoring (and maybe actuating) the water levels in various areas of our garden.

 

We already have a sprinkler system and it works via pre-programmed functions. The problem is that when there are days with different weather conditions (heavy rain, or very hot days), we need to remember to change the functions so as not to wreck the garden.

 

The topology of the system I'm considering is having the sensors being CAN nodes distributed along the bus. CAN is advantageous in that it allows lengthy buses up to several hundred meters with only two pairs of wire (can+, can- and possibly power). The MCU then sits in between the CAN network and Ethernet.

 

I'm considering having this MCU, serve a static web page that is dynamically updated with new readings. The idea here is to have a simple web server in the microcontroller that serves a html+javascript document. At the same time, there is to be a WebSocket server running that will push new data (as well as receive) to the webpage running in the browser of the client computer.

 

The important thing here is that the MCU has to have enough power to provide several hundred KB bursts for the webpage (html and javascript libs are a LOT of text) and maybe some graphics, as well as running the websocket server (very light load).

 

I've used websockets with arm micro controllers before but they never acted as a server and simply pushed data to an autobahn relay (which then pushed data to clients).

 

Although I know how CAN works, I've never implemented it before so I don't know how feasible or whether there are any gotchas in what I'm thinking doing.

 

Feel free to make any suggestions (or even trash my idea mercilessly).

My Project:

 

Programmable thermostat that displays the cost of heating (or cooling) and gives immediate feedback with

projected cost when you make a change. (i.e. when you turn up the heat it shows how much more

that will cost you, or when you turn it down shows how much save).

 

The MPG or gallons per mile displays on cars can help people learn to drive4 more efficiently,

this extends that idea to climate control.

 

(Cost could be in monetary or greenhouse gas units, get temperature data from the house and outside

(possibly in multiple zones using 1-wire or CAN communication between modules),

weather/climate forcast data and fuel price from network interface (from internet)

Display on the OLED or via network interface (on computer, web enabled TV, etc.))

 

Extensions:

 

Interface with other home control devices using CAN (e.g. somethng like Very Simple Control Protocol http://en.wikipedia....ontrol_Protocol

also bridge to X10 serial controller, so can control fans for heat circulation or venting, etc.

Add I/R sensor so disabled family member can use remote to control thermostat.

 

Eventual expansion to other home monitoring/control applications:

Add sensor for when the mail has come, since in inaccessible spot

Add accelerometer as earthquake sensor (in basement - tie in to Quake Catcher Network)

My proposed project:

Create an easy to use interface with an engine control unit via CAN, permitting on-the-fly programming and adjustments to the ECU in addition to providing real-time feedback and display of engine operating parameters.

 

My reasoning behind this:

I am installing a Mega/Microsquirt system on my motorcycle and tuning the unit with a laptop isn't as easy as doing such in a car. The recent MS units have CAN support so this seems to be a natural way to extend it and interface with it. A unit such as I am planning would permit relatively easy adjustment to the ECU- a small(ish) unit mounted on the handle bars providing an interface to the tuning aspects, and similarly being capable of providing a monitor of vital engine functions.

 

I am also planning on using the soon to be released Stellaris LM4F as a general "dashboard" - displaying speed, fuel level, RPM's and such, as well of the possibility of interfacing the two together, providing things such as fluid monitoring and warnings, up and down shift indicators, fuel consumption and other maintenance reminders in order to provide a comprehensive vehicle tuning and monitoring system.

 

I know that, in order to be a viable solution, abstraction is required- dependent on hardware being interfaced with. Anyone who has looked at Megasquirt knows everything about it is quite abstract. ;) This unit would provide the abstraction layer between the ECU and the real world.

 

The dashboard side doesn't require so much abstraction since the sensors are not vehicle specific and would require "calibration" regardless of the vehicle. Sensing vehicle speed requires regular signals from a wheel sensor, RPM's can be sensed from ignition coil sensing, fuel level would depend on the sensor (capacitive or resistive and its range), temp sensors are resistive, etc... all relatively easy to handle via ADC.

 

Being able to combine the "dashboard" with "ECU"-related information could result in a comprehensive system to monitor, tune and otherwise optimize a vehicle's operation... in my specific case, a turbocharged motorcycle (Honda CX500TC), but could be similarly adapted to work with any CAN-enabled ECU and even many OBDII vehicles.

 

I'm not sure though, what I would do with the Ethernet capability, but I could imagine being able to connect to a laptop or such for datalogging purposes would be helpful.

Some nice ideas. I've obviously got to up my game! My kitesurf van project stays for the standalone LM3S2110 CAN board, but I've also got a separate use for the Ethernet enabled board.

 

My initial jump from desktop C# programming to microcontrollers was with a Netduino and my first project was a Netduino Plus based garage door and lighting controller. It hosts a very basic hand-written web server on the device. It uses some XML messages in and out to control the devices and report their state. The UI is either an Android app or a small website served from the micro SD card. All this has been done using C# and the .NET Microframework on a rather rough looking stripboard. I could show you but you might laugh at my soldering. Now it's time for an upgrade. A version 2.0 home CNC milled PCB (with solder mask) is already planned and I was going to continue with the Netduino Plus, but perhaps the brains of the system need to be a bit slicker too. The LM3S8962 Ethernet board would fit the bill perfectly.
