I’m using that exact 2x16 red on black Crystalfontz display in the MB-808. 
If you guys can wait until I make the MBmatrixSEQ (probably early next year, after I finish the MB-808 order and get some of my cash back), I’ll be ready to place that big order for the 2x40 displays…
EDIT: If you’re in a super hurry, I think I’ve still got a couple of the Optrex 2x40 displays from the group buy a couple months back…
K: you already know because I told you I was hoping to arrange a group buy for those LCDs… so you can count me in. I need quite a few though, so I’m not ready to pay immediately.
They are not the same as the ones from the group buy though, those are an older, inferior model.

But they were CHEAP! ;D

i can create wiki, but Doug mentioned that he would be managing this RTI order early next year.
I guess he should approve this kind of name collecting, first.
But they were CHEAP! ;D
Yeh at 1/10th the price it’s hardly a problem
Well I am in for 4 of those Optrex 2X40 screens.. If we start a group buy, for them.
2 for me
Just want to actuallize this thread. No order were carried out, right? I assume at least as many are still interested.

i don’t know about an order. but i’m interested in some. i need at least 3 LCD displays at 2x40 for SEQ and FM. color doesn’t matter, just compatibility

I’m also looking for 3 for a FM + SEQ (at some point) combo. I was looking at:
Cheap option. I couldn’t find a datasheet so it is not clear if these will work or not, but 3 for $20 is hard to beat: http://cgi.ebay.com/LCD-Module-PC4002LRU-BSO-B-Y8Q-40x2-w-Backlight-Qty-3_W0QQitemZ370221534134QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item5632ec4bb6&_trksid=p3286.m20.l1116
I normally use CrystalFontz displays since I’ve had good luck with them but they are pricey. If we did a buy of 10 of these they would be $20 each (so $60 + shipping for 3). http://www.crystalfontz.com/product/CFAH4002A-YYH-JT
Optrex makes a display I rather like (http://www.optrex.com/products/partdetail.asp?PartNumber=C-51850NFQJ-LG-ACN). This is the green-on-black version of the white-on-black display posted earlier. They are bloody expensive though, $40 for one (!) or $32 each for 10 at Mouser. It wasn’t clear to me that they use the industry standard interface, but it sounds like others have had success w/ the white-on-black version. Can anyone confirm this? I might give it a go w/ 1 for the MB FM (next on my list) and hope for cheaper options or a large group buy for the MB SEQ since that’s still a ways off.
I’m really partial to the “negative” displays like the Optrex I mentioned. I wish CrystalFontz did one in 40x2 format…
how about those?
10 pcs for $63.67 including shipping… if one could expect quality ??? for that price…
LCD Type : STN Yellow
Backlight : LED
Backlight Color : Yellow green
White Others ???
Controller / Driver : HD44780
maybe simply try it and share the risk of buying crap?
or go for decent quality with crystalfontz? i think it should be possible to find even more than 10 people with the same need (?)

Optrex are selling them directly for $23 each if you buy a carton. That means you probably would need to buy multiples of 16 or so.
It would be really nice with red negative, but it seems imposible to find if you don’t make a special order of many displays. Green on black would be nice too…

yes red on black looks very good and would make our devices quite unique, i believe it’s just very difficult if not impossible to find that many people who all share exactly the same imagination about their LCD.
so the minimum order quantity for the green on black (which really look great in MB-SEQ) should be easier to achieve…
…but on the other hand having the displays of all your midibox builts in the same color (like red on black, which matches MB6582 very good) would surely be great, too…
ok, i have news from optrex:
Thank you for your interest in our C-51850NFQJ-LG-ACN. We do have 1220pcs currently in stock. To meet the $23/pc price you will need to purchase in multiples of 80pcs which is full box quantity.
and it can’t be paid via PayPal so someone more Native American than me would be required to do it…
…in case we’d ever be able to reach the 80 
& of course there will be shipping cost in addition.

possibly they can source more than the quantity they have?
also these offer discounts

apart from the auction title the description as well as the pdf say it has 2x24 characters instead of 2x40 ???
btw is KS-0066U the processor we need? there’s just KS0066 mentioned in DokuWiki: http://www.midibox.org/dokuwiki/doku.php?id=lcd&s
…AND has anyone made some experience with those data image LCDs in the ebay auction i mentioned a few messages above? as they have the right controller (HD44780) they should at least be compatible, but does anybody know about the quality?

Thanks for checking into it. 80 pcs sounds like quite a lot to me. I’m in the US so I could run an order for such a thing, but I would think it would be difficult to get up to 80 pcs. I found a thread a few weeks ago that indicated this display will work with MB projects (I’ll have to find the link). Apparently the Optrex displays are a bit wider than the “standard” (i.e. CrystalFontz) but they will still *barely* fit in the mount holes on PCBs (like Wilba’s MB-SEQ, etc.) without modification.
So…anyone interested in these displays? Green text on a black background - http://www.optrex.com/products/partdetail.asp?PartNumber=C-51850NFQJ-LG-ACN
i have some trouble with the computer atm…
ok if we can achieve the $23 price i’m in with 3
but it appears quite unlikely, somehow
