From a source we are feeding the loop with fresh speech that is recorded on one of the players. When the tape is filled we change the switch and record what is played on the other player and what is said in the room. The looping continues for a few minutes until you can't hear the speech anymore and the switch is then changed to speech source.
Limiting us to only use analog techniques we are controlling the switch with two turntables. The first turntable control the motor for the second turntable, making it run a full lap in about 6 minutes. On the second turntable we are using a reading fork (läsgaffel, LED + light sensor) and a record with a drilled track. When the light sensor picks up light our switch will be set to the refresh state and when there is no light on the sensor we will record the loop.
All that is left is just making it work. Which proved to be a bit harder than what we expected.
That is all for now.
