    Can it have more than just Arduino? There's lots of other microcontrollers out there. I think a Micro-controller sub-forum would be great though!

    I'm working on finishing up a VCU:
    https://developer.mbed.org/teams/eVCU/

    Based on an NXP mbed footprint, but can also use LPCXpresso boards.
    7 Analog 0-5V inputs
    1 Analog 0-5Voutput
    5 opto-isolated digital 12V inputs
    1 Reset input
    6 PWM FET outputs
    6 FET switched outputs
    2 Opto-Isolated CANbus ports
    1 USB Host port
    1 RS232 port
    1 Xbee socket (Can be used for xbee, wifi, bluetooth, celular xbee-formfactor cards)
    12V input with internal DC-DC to get 5V and 3.3V levels
    5V output for powering sensors
    1 Internal microSD card slot
    1 internal backup battery for RTC

    All of this is inside a sealed CINCH enclosure with 48 pins.

    Nice with Arduino part of forum

    I self used a Particle Core (Arduino simular with built in Wifi) connected to my Cycle Analyst during Winter storage of my motorcycle in garage and monitored AmphereHours and Voltage of my battery pack.

    http://docs.particle.io/core/hardware/

    Cycle Analyst sends values 5 times a second, a particle core receives serial string, parsed it, read values and send values through Wifi to Google sheet every 15 minutes.

    Good to know how battery pack is doing.

    I can share my code if it is interesting...

    I built a spotwelder.

    DSC_0056.jpgDSC_0064.jpg

    Need to dial in my spotwelding techniques.

    The arduino controls the whole thing and is adjustable on the spot via the pot and buttons, all while visible on screen.

    The arduino monitors the ac input to determine the correct time to switch on, using the AC line peaks as the switch on point when the button is pressed.

    If anyone wants detailed schematics or code let me know.

    I'm considering a simple CA replacement (have two controllers now) with a small display where the temp gauge currently sits.
    A good place to start is http://tronixstuff.com/tutorials/ if you want to get into Arduinos.
    Sal Park also did some work in terms of current sensing: http://sourceforge.net/projects/bangxietymeter/

    Edit: found a CA replacement & throttle tamer Arduino Nano based: http://endless-sphere.com/forums/vie...hp?f=2&t=61407

    Working on deciding which direction I will go with my battery monitoring. Still deciding between a pure High and Low voltage cut-off without further information or If i want some more grunt.

    Got my high and low voltage cutoff workout with an celllog8m with my own isolation/discharge balancer/on off circuit. This way i can safely interface the celllog output with an normal relay or micro.

    The cost of the design without the pcb is down to roughly 2.32 euro's per cell. A little high for the basic functions, how ever I am working on a more powerful puppy based on a ltc6803/ltc6804 and atmega328p (arduino bootloader possibly).

    See the attached files for my current design.

    Hi guys, I'm new to the forum & not new to micro-controllers

    I own quite abit of hardware. I have a mbed, arduino & raspberry pi. I will be using the arduino along with the raspberry pi for the instrumentation of my bike. I removed my cluster completely & will be replacing it with a colour touch screen. On the screen I will be displaying all the vitals (soc, amps, speed etc...). I will be using web technologies to display the the gauges on the screen.

    For those wanting to get into Arduino from a web programming background. If you are comfortable with Javascript you can use Node.js with the Johnny-Five library. This library allows you to program the Arduino via Javascript & illuminates the use of c++. I'm using Johnny-Five on my project.

    Here's a video of me controlling my indicators via Arduino video

    The possibilties with micro-controllers are pretty much endless...I have so many ideas similar to furyphoto.

    For anyone that may be interested, I have a 4.3 lcd mbed enabled board with ethernet, sd, can bus, serial, etc from embedded artists if they wanna mess with it. I just won't use it. Would be good for this kind of stuff.

    got myself a more powerful arduino compatible micro. The teensy 3.1

    Powerful enough for anything i can think of inside of an electric vehicle, besides an instrument panel.

    Also adapted an LTC6804 to an 2,54mm headers so i can easly build test circuits.DSC_0098.jpg

    tomdb, are you implenting the teensy on your bike?

    What time of hacking do you do?

    Sounds like a shield you describing.
