Standalone Arduino chip on breadboard

If you're like me, after I got my Arduino and performed a final programming on my first chip, I wanted to pull it off my Arduino Duemilanove and put it on my own circuit. This would also free up my Arduino for future projects. The problem was that I'm such an electronics newbie that I didn't know where to start. After reading through many web pages and forums, I was able to put together this Instructable. I ...

General Instruments SP0256-AL2 English Phoneme Speech chip & an Arduino

The GI SP0256 chip is an early 1980s bit of technology. It's a 5V (to 7V) NMOS chip which is compatible enough with the 5V TTL circuity common in that era. 5V TTL disappeared for a while, then came back with the Atmel _28-based Arduino boards, many of which run at 5V. The SP0256 chip contains a [crude] electronic model of the human voicebox, and the -AL2 variant comes with 59 English language phonemes built ...
