Thread: Arduino Modular Engine Sensors Unit (~$50)

I won't likely be developing any phone apps. To much work for limited use. And this really deserves a dedicated unit.

I got the nano, it's the cheapest arduino. Is recommend that if you want to easily copy my work. Though any arduino will work.

how about the fusion brain from mp3car.com? US$60 and has shedloads of analog inputs...

It looks more or less the same as an arduino, but a faster processor.

Please note: This is a hobbyist grade product. As such, limited or no documentation is included with it and advanced technical skill may be required to use it.

This kind of scares me.... Without researching any further, the Arduino has quite a lot of documentation online and there are Arduino models available for about half the price. So although they are similar, I would always go the one with better online support.

Looks like a good site though - thanks.

suggest you read the forums, there is plenty of support info out there, but it doesn't come as a documentation pack with the hardware... more of a forewarning than anything else... I'm sure there are plenty of arduino owners who haven't got a clue about using one either, and yet they buy it.

Can you make a stepper motor driver version so we can replace crappy factory instruments with ones that work? Thinking rev counter, fuel and temp.

I can do the hardware side, just need stuff to drive it.

does look impressive Mp3Car Custom Car Computers! would def be good if you need that much, i dont though.

just for your interest though:

Is it pandering to old technology to have physical needles/pointers moving on a dial yet having to use stepper motors and controllers to achieve that outcome. You could just have displays that generate a graphical representation of the dials and needles simplifying the whole thing.

There is nothing like a good old mechanical dial even if it is driven by a digital circuit
