Doorbell

A virtual doorbell that allows people without a card to access the space easily, by alerting members in the space using audio, visual and push notifications. The system is based on a Raspberry Pi, which serves a responsive page like the one below, with a field to enter your name, as well as the hackerspace status. When a person rings the bell, a warning light is turned on at the space, an audio alert with the person's name is played, and optionally a push notification can be sent to those who want. The person who rang the doorbell sees a progress bar with the (estimated) progress of the member who is coming to the door.
