“BroHogan” explains his “X10 Book – First Edition:”

A “hollowed out” book is used to house an Arduino which is interfaced to a PSC05/TW523 X10 module. The book will display the X10 signals on the power line using descriptive names. X10 type “macros” can be created and it will also send commands entered by the TV remote. Scheduled commands can be sent as well.

One or more of 8 LEDs and 4 relays can be set based on the “profile” of the command received. A tilt switch reorients the display so the book can be vertical or horizontal.
