Tinkerlog got their hands on a color LCD from SparkFun and set it up to receive images from Flickr. These color LCDs are 128×128 pixel and the include a breakout board with a separate power supply for the backlight. Communication is via a three wire SPI bus plus a reset line. [Alex] used an ATmega48 for control, which is connected to the computer using an RS232 to USB converter. The wiring schematic is here.
For the software side of things, he adapted Sparkfun’s example ATmega8 code for the microcontroller (he couldn’t get the Arduino code to work). Beej’s Python Flickr API was used to grab the images. The Python Imaging Library converted them, and finally, they were sent to the display using pySerial. SparkFun has been offering these displays for quite some time; it’s good to see a quality writeup of one in use.

Here is the 3.3v switching regulator I just ordered. It comes in 3.3v 5v and adjustable. Disclaimer I have nothing to do with this company except as a parts source.

Nokia screens are nice however beware that they come in two flavors in regards to the lcd controller board. One is an epson controller while the other is a philips.
