Fans of the original "Star Trek" can now recreate the wall communicator units as used on the Enterprise in a short period of time thanks to Instructables member FredO2 - whose wall comm replacement is made with an Arduino, some hacked walkie-talkies and some 3D-printed enclosure parts.
The new system allows for sending the various boatswain signals and for the recipient to reply via radio in the classic fashion. Furthermore an alert and siren/klaxon can be sounded at the press of a button. All very good fun and ideal for amateur theatre, a different form of intercom or just for fun.
If you have heard about the Arduino development platform and wanted to learn more - you can't go past reading a copy of "Arduino Workshop - A Hands-On Introduction with 65 Projects” by John Boxall.
Arduino Workshop takes the reader from having zero knowledge about the Arduino platform, electronics and programming and leaves them with the know-how and instructions on everything from blinking an LED, to robotics, wireless data, cellular communications, motor control, sensors, Internet connected systems and more. For more information including a sample chapter and table of contents, visit the book page.
