GI: "YarGauge" replacement clock module (Digital Tach, etc.)

[Kioshi]

CTScott, I use to use this mp3 player back in high school - http://asia.cnet.com/reviews/musicpl...6925p-1,00.htm

It used OLED technology and I was able to read song titles walking around the border of the school during lunch time in the sun.
I don't think it should be a problem i the YarGauge as well because the cluster sits a little angled down in the area, doesn't it? it isn't directly sitting flat per say....at least when you install/remove it, it mounts a little tilted...

OLED displays are very nice and produce rich colors and deep blacks, but their worst flaw is daylight visibility, which is pretty weak. I wish OLED had great visibilty in the sun but they do not. The reason being is there is no backlight which is found on a traditional LCD. Instead, it uses a bioelectrical chemical to light and this washes out badly in the sun.

Just warning you before you make a mistake and buy them.

That was my impression as well. The VAR that is sending me the samples claims that they are a vast improvement over earlier generations of PMOLED displays. I guess we'll see. As Kioshi mentioned, the display is not in direct sunlight, so perhaps the high contrast ratio behind the smoked lens will do it. The gas gauge is just a backlit transflective LCD, but it is a higher contrast one than I've been able to source.

LOL unresolved issues?


Getting psyched this thing is getting close to completion CTSCott. I'm sure you'll sell a ton, to Garm atleast :P Hope it isn't hard to swap it in there.

Na, just has to say something always..

Yup, one of those ppl

What posts are you referring to? I don't know what you guys problem is.

I'm sorry if this has been addressed already in the thread but I have a couple questions:

Will this work in a Canadian Yaris? I have a 5-door automatic with tach. I'm guessing probably yes, but it'd be nice to be sure.

Were you able to come up with instant fuel economy? Especially interested in L/100km if possible.

EDIT: I searched the thread and found both these questions were answered. Looking forward to seeing this project to completion, and likely buying up one myself if possible!

Teddy -
Since you asked before searching, you have to go to the back of the line!

j/k ....or maybe not....

I received my sample OLED display today and did a bit of experimentation with it tonight. The display is amazing on the bench, but they all start out that way. This display is a 16 bit color OLED display. For initial testing I am just running it with white text on a black background.


I mounted it in Crashy's cluster for a quick test and will put her cluster in my 09 tomorrow to do some sunlight testing.

looks nice

Small text, but it looks BEAUTIFUL!

[Nexus1155]

kestion. Are the RPMs reflected in real time or have a slight lag to it like some digital rpm display readings?

Also, does the text change color :) or backlighting w/e?

[CTScott]

The text is actually bigger than the two prior displays that I tested. This one has programmable fonts, so I loaded a font that maximizes the space of the clock display opening.

The data is more realtime than other comparable devices, due to the speed of the CAN bus processor that I am using. The hysteresis of the display becomes the limiting factor.

The text can be any of 65535 colors with this display. The background can be any color as well, although the manufacturer recommends bright text on a dark background, rather than dark text on a bright background, due to a smearing effect that happens with OLED displays.

There's not a cloud in the sky this morning, so today will provide a good test for the sun glare visibility of this one.

I am rooting for you.

Man, you are one intelligent person. Wish I knew how to do these things!


GL!!!!

Just what I wanted to hear. I was also thinking color for those of us who want to keep it stock looking or go with our already red motif ;)
