Control your IR devices via SMS
As the site clearly indicates, "The purpose of this circuit is to make the human life better and easier," and we couldn't agree more. If you've got an ancient Ericsson lying around that would otherwise be ready for the recycle bin, this circuit gives your faithful friend a new lease on life as an SMS-actuated IR sender capable of controlling up to eight devices, depending on how you opt to build it. A simple 8-digit text message to the phone is all it takes to send the appropriate ON or OFF signals, and as an added bonus, the author shows you how to wire the phone directly into the circuit so a battery's no longer required. A better and easier human life, indeed.
