Tweet-a-Pot: fun but unpractical
You’re big fan of Twitter, DIY and like coffee then project Tweet-a-Pot may be interesting for you. The idea is following. A coffee machine is connected to the PC via small but power Arduino Board. Arduino IDE and Python should be installed on that PC. A simple Python script checks a status of your Twitter account and sends ON/OFF command to the coffee machine via Arduino Board according to the status.
Well, the Tweet-a-Pot looks very interesting for study home automation or play with Arduino Board. Practically it’d be much better to use X10 PC interface like CM15Pro and appliance module together with X10 Commander. Additionally you will able to connect more devices and lighting control. You’ll need just additional X10 modules for that.
