Locative media - phone

without comments

Although most modern telephones have GPS installed - this project takes things a little differently. An old rotary phone is connected using the phonebox to a GPS antenna. Stories are being recorded and stored with location data in the device. When the device re-visits the location, it will give a phone call using the earlier stored message. See the phone in action on the ‘kunstfietstaxi’ in the following clip:

The electronic system has been used in a stand-alone ‘voicemail-box’ and in this GPS-enabled taxi phone. The voicemail box (’phonebox’) is on display at the ‘MultiSolo’ exhibit. More links on the taxi are the following: ‘kunstfietstaxi’. - see also youtube or this clip and TVenschede.

PhoneBox: retrointerface for phones

without comments

Yezz! another retrointerface ready. The phonebox simulates all necessary signals to operate a rotary-dial style telephone to any other device. Dialed numbers are put through to a serial port. For audio connection a line-in and line-out are given. The board puts a 12V line-voltage on the phone, and can also generate the 70V - 20Hz voltage for the ringer. Technical details will be put on the wiki. The schematic is inspired by the linesim design, but uses a microcontroller (atmega168) and has amplifiers for audio in- and output. It works with standard (dutch) rotary dial phones (Ericsson T65 and older)

It has been used in a stand-alone ‘voicemail-box’ and GPS-enabled taxi phone. The voicemail box (’phonebox’) is on display at the ‘MultiSolo’ exhibit. A GPS enabled version has been installed in a taxi-bike called ‘kunstfietstaxi’. - see also youtube and TVenschede.
