Electronics Goldmine essentially carries surplus stuff – so it’s often both the case that the items are heavily discounted, and that they are discontinued – so you likely couldn’t order them from a supplier. Besides, why have two places with the same stock (at likely the same price)? Just pick them up from Electronics Goldmine!
Incidentally, I’ve used their Sony ACX705AKM 2.8" LCD ( http://www.goldmine-elec-products.com/p … ber=G13752 ), and have a full tray of SED1375’s if anyone else is interested in experimenting with them.
But you are forgetting that it is cheaper to order something from one place than to have to make 2 orders. By consolidating the two you save on shipping. I also think that they are good values and more people know about Sparkfun than about Goldmine in my experience, so it would make it available to more people.

So ask Goldmine to stock SFE’s products…

Can you tell us more about your project? Any PIX or video?
I must be misreading the datasheet, but from what I read, you can only
control which color of each pixel is on or off, making it 3 bits per pixel,
or 1 bit per channel, 3 channels per pixel. Is this correct? Seems kind of odd…

The above is meant about the two large LCD’s from the OP.
Hi there,
The ACX705AKM is 9-bits per pixel, but you can just disregard the LSB for one colour to make it 8-bits per pixel.
I don’t have any pictures or video to share (unfortunately), but controlling the LCD is pretty simple once you get the code working. I’ve controlled it with as little as one dsPIC30F3012 (a low pin-count microcontroller) manually sending out the sync and colour signals, plus one crystal and some power regulators. The one large project I built with the display uses a dsPIC33FJ256MC710, which has 100 pins, and one of the SED1375’s, which will do all the low-level sync and stuff for you. I use a few banks of I/O pins from the dsPIC as address and data lines for the SED1375, and just wrote some handy function wrappers to bitbang pixel data through that makeshift I/O-pins-as-an-external-bus-interface interface. I can’t remember the max framerate I could get with that interface, but it wasn’t huge – it’s a style that suits situations where you only have to update a few parts of the screen (like a few areas of your GUI), rather than an entire screen constantly for something like animation.
Still, it was the very first colour LCD I interfaced to, and it was a fantastic experience the first time I saw those pixelated happy-faces display on the screen.
