MPGuino colour touch

Yes I do mean instant

I suggest we keep 'current' as 'current' or 'possibly short trip' or even 'current trip'? DTE l is a bit ambiguous IMO - my initial thought was that it might be from the last X minutes of driving - sort of like a Prius histogram.

I could see one screen setup for long distance drives being useful where DTE calculations are front and centre. It's also fun to watch your DTE increase as you hypermile, and this could be a good incentive for some.

So yes, definitely happy to give other people's screens a go. With the current Guino or SG you don't get a lot of freedom, so you have to prioritize a bit more.

Hey mate,

I think that's what you were after?

Now.. I don't think I'll change the terminology on the DTE trip name.. but you can call it whatever you like on your screen..

Reason is.. It is used to set the DTE calculation in a way that suits your driving.. be it a long long term average so you know what your normal driving will deliver.. or you can reset it if you jump on a highway and want to see what to expect from new circumstances.

It cant be calculated off of the tank, as every time you drive away from the servo the average goes about 4 times what is normal, and takes the entire tank to normalize towards what is expected. And the theory on a time based recent trip amount has too many inconsistencies that wont be controllable or desirable for knowing exactly what's going on.

I'm happy to name it 'current' if you prefer to see those words on the page of your design, and you may prefer to just see what your short term average is or to use the ODO for trip measuring, but the 4 people that use this here do a split of long term, or fleeting short calculations, all for DTE use. Which is handy for timing refuels and weekend plans (fuel prices here in Perth are cheap on a Monday, and its extremely useful to at a glance see if you need to top up 15 litres at a 20% higher price or if you'll breeze through your planned trips before cheap day comes again)

Happy to make alterations, but also looking to keep things easy and controllable by the end user

My screens look great!

One suggestion for the graph, this could be asking too much but it would be really cool if the segment that represents 'current' could be picked out in another colour - say red. That way you'd have a graphical representation of whether you're above or below your target.

You could probably see this out of the corner of your eye without having to be forever reading the numbers.

This could also be an alternative use for the triangle of death. Rather than DTE +5 just DTE +0.01. The goal being to always keep the triangle off. That's kind of how I drive my van and that's how I get 6.7l/100 out of a 2 ton vehicle around Perth CBD.

I just got my Celica licensed today, so I'm keen to get my hands on one soon

Nice idea. Added

I think I'm on the verge of complete triangle of death removal.


Also, good work! I had my 2004 4.7L V8 Landcruiser at an all time best of 12.8L/100 over a 134L fill. Over a 1000kms out of a v8 petrol was no easy feat :P Had to do a few roe highway runs at 90 to keep the average down :P

I like the triangle of death. Just need to think of a more subtle icon IMO.

It would actually be interesting if it could be a user controlled variable. +5 is a bit silly to me as I know if I'm accelerating hard or climbing a hill etc. Coming on at just over tank AVG could make it a fun game.

But just as it stands l'd rather have it then not. It's also possibly useful as an eoc indicator.

I like the instant above tank average idea.. There's visual on the graph for the current average. this could be good

What symbol do you have in mind?


Parts and new PCB's with voltage capability are arriving soon to make 4 new units. I'll sell 4 at cost as evaluation models for testing

[oldtamiyaphile]

Could just be a pilot light that comes on (or goes off).

Could possibly be red when you're naughty and green when you're nice.

Whichever method seems to work in peripheral vision would get my vote.

Subscribed. Nice product!

[abbalooga]

How's that?

[oldtamiyaphile]

Looks good

Is it still going to be just ground and VE+ for power (no switched input)?
