OH NO!! not LCD again.
i've done a parallel connection from the LCD to an AMD controller board
for my Senior project in college.
it was a nitemare trying to connect that tiny sucker!!!
if you are lucky..you might be able to find a socket that
sits perfectly on the LCD pins.....
if you are unlucky, like i was, you will end up soldering each and every pins
on the LCD to the socket....and that doesn't guarantee for it to work

not to thread crap..but i strongly suggest those of you who don't have any
eletronics background to stay away from it.
it costs money to buy the soldering gun, solder, voltmeter...etc
not the mention the time you gonna spend connecting the LCD pins..
trying to solder pins inbetween each other is very difficult!
the pins are about | | that much apart...
and your solder tip is about this fat: | |
V

just wanna share my experience

Ziptar, i have to admit..what you have done looks REALLY nice. eventho i have all the
tools and parts in handy..i'm gonna stay away from this hot deal....thx for the info and the links.

BenRosey, after you've wired everything together and are certain that
your connections are correct. you can turn on the computer and double check your
voltage at each connected nodes with the voltmeter. the pins that needs to have 5+ volts
must show 5+v (or 4.7 or above) on the voltmeter and 0volts(or somewhere close to 0) for the corresponding pins.
 
So I guess no one is interested in making one of these for me then?

I would love to do it myself, but I don't have the tools, and really don't feel like buying them for this one thing.

I know this is a little bit OT, but does anyone know how the wiring out be different for this (with the LED backlight) than with an Electro-Luminescent (EL) backlight? I really like the blue glow of the EL ones, but I hear they require an EL inverter, of which I know nothing about. In either case, I think I'm going to give this mod a whirl.

Thanks for all the info, Ziptar!
 
Thanks for the idea Ziptar, it looks like fun. Some very fine soldering skills needed though, and a fine tipped iron - not for the faint-hearted. Here is another link I found that deals with a 20x4 display. I also see that you can get 40x4 displays for $20 elsewhere on the web.

That was all good when I was setting this thing up, they just seemed to crap out a few seconds after I turned them on. The screens would go solid black and now they just have a few of the characters on the right side that illuminate. However nothing displays when I run the software. It's not a big deal I guess, I've moved on...

EL does require an inverted, they can be expensive, they run about the same coast as the LCD in most cases.
 
Hey guys I found another one at BG check this out. 16x1 Looks to me like this one is wired up and ready to go for a DB 9 connector.

EDIT: Oops, forget to mention this one's VFD.
 
where would you get the 100 ohm potentometer from (cheap, of course 😀)

went to my local radioshack and only found a 100k ohm one (big difference)

hmmmm nice, If the serial board is removeable like it says, that's a good deal. You can possibly use the serial board on another LCD (like the 20 x 4) and it's half the price of a serial controller.

wassup: I got mine for $.89 at a local electronics store (not Radio Shack).

Do you have any info/links on how to hook up an EL LCD with inverter? I think it's the one I want, but I have no experience with it.
