History

Bemix version 1.0 was created in Spring 2005. It was designed to play music in the Bemis bathroom through speakers located above the drop ceiling. Users would select music through Glirnath, a web interface.

Later, a touch switch was added to provide on/off control from the bathroom. The touch-switch was hidden in a towel rack in the Bemis bathroom. When someone touched the towel rack and the faucet at the same time, the op-amp senses the change in voltage, compares it to an internal reference voltage, and amplifies it. This signal is sent to a flip flop which toggles power to the speakers.

The success of Bemix led slugs to plan its expansion into other bathrooms. But, the v1.0 hardware and software had much room for technical improvement. The touch switch was finiky and there was no way to override the touch switch from the computer.

Bemix version 2.0 was planned but not implemented. It would have simply built on v1.0, expanding it to the three central bathrooms and making it more robust.

Version 3.0 is a complete redesign of version 2. It will be PIC based and will communicate with the computer over the 4E Network. This will allow a virtually unlimited number of commands to be exchanged between the bathrooms and server. The user interface in the bathroom consists of five touch switches in a + configuration.

Cable Trays

All low voltage wiring Bemix must be run in a cable trays, because messy wires start fires. Our cable trays are from Reuse and currently being installed.
