Telecommunications National Museum

By Picolab

The Telecommunications National Museum in Colombia, opened in 1980 and was renewed in 2018. As part of this renewal, Picolab developed multimedia applications for the next experiences:

Telegraph (Coded message): Development of a circuit that captures pulses in a telegraph replica, and reproduces the Morse code and decodified message on a tablet. Telephone (Voices on the other side): Development of a circuit that identifies when the user picks up the pjone to reproduce an audio. Radio (Music for all): Development of a mechanism to couple a record player needle to a circuit for identifying the position that the user selects. Once the position is chosen, a tablet displays the cover page of the album and reproduces the audio track according to the position. Commercial Television (Audiovisual memory): Development of a mechanism coupled to a TV knob for selecting a video track. A tablet reproduces the corresponding video, according to the knob position. Technology: IOIO Hardware + Native Java Android. Educational radio: Development of a mechanism coupled to a Radio knob for selecting an audio. A circuit plays the corresponding track, according to the knob position. Educational TV: Mobile application with a series of video clips that the user choses to play, pause or stop. Timeline (The world in your pocket): Android SmartTV application with a timeline with the history of mobile phones. Connected to the world: Standalone application for saving messages with three possible media: audio, letter, morse code.
