Technique
While developing the project we found that it was crucial to control the horns from one central point instead of having the taxi drivers play from a score.Therefore the idea presented itself to use a remote control in the form of a transmitting system for the horns. The system had to be both simple and usable anywhere in the world. This was easier said than done: we had to build a system with specially designed hardware. Nevertheless, we decided to build everything again from scratch in New Delhi, Berlin and The Hague, as the system did not perform as expected.
We are now using six telephone channels distributed among the cars via walkie-talkies. The system is functioning without any disruptions now, but we still need to make it more precise, simpler and cheaper.
