Bemix is a music system which plays user selected music in the Bemis bathroom. Residents can select music over a web interface and can turn the music on and off directly from the bathroom or remotely over the web.
There are three versions of Bemix:
- Bemix v1.0 - the original version, it has since been uninstalled to be upgraded.
- Bemix v2.0 - the current version and will be installed shortly.
- Bemix v3.0 - this version is under development.
Bemix v1.0 was designed to play music in the Bemis showers through speakers located in the Bemis bathroom. It plays music selected through Glirnath, a web interface. You can control it via Glirnath or a touch-switch located in 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.
