And this week’s project:- Take a single OLED module and three spare displays, and mod it to display the same or different data on four displays at once using the infamous “CHIP ENABLE” line trick. IIRC the internal controller on the display can store current data so this might just work.

512*128 full colour anyone? :) this would own on the front of a PC’s optical drive cover.

Â£15.15 from Farnell for any other UK fiddlers, which isn’t too shabby, however according to their site once the stock is gone, it’s gone and there won’t be any more.
As Farnell are where Newark are sourcing it for US fiddlers, this could become a problem unless somebody can find stock anyplace else?

6: I hate sparkfun, they have nice stuff but its always so overpriced.

newark has the same display for $23, but sadly theres a $15 handling fee per order because it comes from the UK (http://www.newark.com/densitron).

Hopefully there are better options available elsewhere.

@7: the project could be “art” by using the clock to count down its own expected display life. :)

What about someone publishing a way to use the OLED modules found in mobile phones? I have a few here from old e700 samsungs but they are less than helpful with their datasheets even though the chip used is current.

It looks like you just clock in the line data serially and feed the OLED the correct voltages.

OLEDs are freaking cool.. I’ve had my creative zen stone+ for a while and it still draws some attention (being a non-ipod). The only prohibitive thing about this watch is the relatively low lifetime of the display.. in the thousands of hours

There's a bit more information here http://code.google.com/p/arm7-oled-clock/

It seems he used the OLED available at sparkfun http://www.sparkfun.com/commerce/product_info.php?products_id=712#

No Schematics etc…
Is there any significant differences in implementing OLED rather than LCD?

@alex: Because if it’s capable of color, it totally needs to use as much color as possible…

I wonder if that was flame bait to get people shouting “IT’s an OLED, not LCD!”
