MPGuino

[fastegg]

Does any one know where i can purchase a fully assembled MPGuino ?

[meelis11]

I have made some custom mpguinos where buttons are in separate small board (and buttons-in-top version) so you can flush install mpguino and put buttons somewhere else.

I have also made custom code just like I like it
extra features:
* added metric version (must choose before code/firmware uploading, no change possible in settings)
* bargraphs (shows 2min average 5-9L/100km - dropped 0-5L to gain better resolution)
* battery voltage
* trip cost (in settins you enter fuel price)
* tank and current trip time in hours.minutes
* saving tank trip data to eeprom (dont forget it when disconnected)
* some values are shown in integers (speed, rpm)
* removed leading zeroes (instead "012.45" shows " 12.45")
* added dragrace screen (0-100km/h time, 400m time and trap speed, calculated horsepower)
* using Atmega chip sleep mode (consumes about 5milliAmps versus 20milliAmps when in sleep)

here are some pictures:

Mpguino is built in custom etched PCB and is same size like LCD (sits behind it, electrically it is compatible with "official mpguino"). I am using atmega 328
I think it would be around 59 euros + shipping. I have some pre-built MPGuinos at home

Hi... how much to purchase and send one fully assembled to Australia ?
One in metric, buttons attached and with all the read outs...

[fastegg]

How does it read fuel usage ? like, is it milli-litres per km or what ?

Shipping is 4.50EUR, so I can make it 63EURos. I haven't send anything otside estonia and dont know how money transfer goes...I have paypal accont, probably it is quite easy with paypal.

I am not sure what you mean?
* normal consumption is L/100km
* then there is readout for consumed fuel for current and tank trip (just Liters)
* there is also Liters/hour - good for measuring idle consumption

Hi Meelis ... so how do i go about getting one of your pre assembled units ?
and was it you that made that neat cardboard box to put it in ?

Yes I made cardboard box for my mpguino and covered it with tape.

making case from thin cardboard:


MPGuino ready, case covered with tape:


Shipping and payment details we can discuss in private message.

Hi Meelis,
You have some nice features on your code. I've been looking for a voltage meter for my car for some time now. I would be very interested how have you changed the code to get the battery voltage for MPGuino.
Is there any change that you could publish some parts of the code (*.txt format)
I also have a atmel 328 on a arduino dualemiloluevemilouvumilou..thingy and I have done some small changes to the code for my own needs.
-Disabled some display screens I don't need, just to make it simpler and easier.
-Litres/hour, Litres consumed, Speed, rpm on one screen.

I used the code from mluckham as a base since it had the version for kilometers and it was very well commented.
Canadian version for kilometers

Hi,
I made topic about this battery voltage thing some time ago:
new feature idea: battery voltage

You must change schematic little-bit: make voltage divider using two resistors

This is fantastic, thanks meelis11
