If you have an old Nokia 3310 cell phone collecting dust in a drawer why not put it to use? This Nokia 3310 Cell Phone LCD Digital Thermometer project uses a one wire DS18B20 and a Microchip PIC 12F629 microcontroller to take control of the old LCD directly. There is code, schematic and a foil pattern available on the site.

I hope this works on a old Samsung LCD with a little convincing. I ripped an old one apart last week for some parts, and it would be nice to use that LCD.
