Months ago I purchased 4D Systems’ 1.7″ uOLED from Sparkfun. As you can see it’s an amazing little piece of hardware.
The resolution is 160×128, 65K or 262K colours, and the interface is serial RS-232 making it easily wirable to a microcontroller or pretty much anything that can send serial commands.

Telit are the makers of a series of “m2m” (machine to machine) cell network interface modules. That is, little all-in-one modules that you can put in your own electronics project to give you cellphone capabilities. Thus there’s one in my plan for the RetroTAC.
Telit GE863
Telit have recently updated their website and it is a LOT easier to navigate now – well done!

RetroTAC Cellular Phone
This project is all about replacing the guts of a classic 1990’s cell phone, the Motorola StarTAC, so that it works on modern GSM networks and can be used day-to-day.
It is based around the Telit module GE863 which supports quad band GSM, serial interfacing and even has a SiRFIII GPS chip inside. It will be hooked to the other primary component, an AVR ATmega microcontroller.
Coupled to the GE863 will be the original StarTAC’s microphone and earpiece, a GSM antenna and sim card holder. Coupled to the AVR will be the original keypad and a 4D Systems 1.7″ OLED display.
Power will be provided by an aftermarket StarTAC Li-Ion 3.6v battery and either an original StarTAC charger or a modified one.
Well it’s back – I reinstalled the Wordpress blog after seeing this lovely Mac-like theme for it and I’m going to give it my best shot at using this site to publish whatever it is I publish.
