GI: "YarGauge" replacement clock module (Digital Tach, etc.) - Page 25 - Toyota Yaris Forums

Nexus1155 · 08-18-2010, 12:34 PM

I have a USB JTAG Cable, I would buy a full working product when it comes out if it integrates nicely, I just can't tear apart my gf car just to test stuff :( Wish I could.

I hope these are finally available by Christmas!

I found a new LCD this week that I am hoping will overcome the sunlight visibility issue. It is an OLED display, which is supposed to have excellent sunlight visibility. I should be receiving my sample this week to test.

Good to hear. I thought those things were in very short supply. How does using an OLED display affect the final price?

OLED displays are finally becoming readily available and no longer crazy expensive. The original LCD was costing me $12 and the OLED is $72 in quantity, but to have true daylight readability will be worth the extra cost. This display was over $200 when I looked at it a year ago.

Standalone devices like the scangauge can get away with <$10 LCDs, because of location. The killer for the YarGauge is having it recessed behind the smoked plastic of the cluster.

A non smoked lens will do the job as well right? maybe finding some way of reproducing the same lens but in clear and at the same time everything else will be mo readable during the day

what will be cheaper the OLED display?

Unless it is Super-AMOLED, which I highly doubt, you have it backwards.

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.

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...

i'm in for one!!

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.

Yup, one of those ppl

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.
