The Pi CPU is that of a cell phone. With the right software it could certainly do the job, and be fast-booting and low power as well. You'd want the A variant, or a Zero, to avoid unused hardware parasitics.
How are you at bare-metal programming? You'd have to replace _everything_ with your own custom software. Not a road for the faint of heart. Better to use an Arduino, which is aimed at exactly the kind of project you are talking about. But a 555 is cheaper, simpler, and easier, if you're not going to add features to the original AC system. -- Jim _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
