This was a project as intern at YOKE for the Red Cross HQ in Copenhagen. The exhibition at Red Cross contain of 6 different rooms with different simulations of different situations such as a prison, wars zone, refugee camp, medic in war, car crash and domestic violence. I worked with the development of an interactive phone installation for a room about domestic violence. When you picked up the phone you hear different interviews with people working against domestic violence.
The phone installation consist of six phones that play a conversation when you pick it up. The look of the design for the phones are retro inspired. The phones are designed so the visitor could easily pick it and put it back. The body is laser cut and the phone is a retro handsfree gimmick for your mobile phone.
The top of the holder works like a wiggle board, the button is pushed down when the phone is on the mount. The button is released and a sound plays when someone picks the phone up. To play the sound a Adafruit FX sound board was used, the board plays a sound when receiving a ground signal. This is the circuit and the wiring of the phone with the sound board, amplifier and power supply.
As part of the rest of the exhibition the other rooms needed a trigger for a soundscape to start playing when a visitor walked in different rooms.
This was solved with a motion sensor and the Adafruit FX sound board. The sound board plays a sound when it gets a ground signal. So I had to invert the signal from the PIR sensor so it gave a ground signal when trigger. You can see the wiring in the schematics below.
