Classroom Area



The Classroom is used for a variety of group events and hangouts. This space features a projector, sound system, and large table for collaborating with many people. It is comparable to the Lounge Area, though the Classroom lighting is brighter.

It is ideal for planned events, such as:

  • Lockpick Sport
  • Events
  • Movie Night
  • Ad-hoc Presentations / Collaborations
  • “Work From Denhac” Day

How do I project my computer or YouTube video?

There are three dedicated ways of displaying content on the Projector:

  • Chromecast that is always hooked up and labeled “Hatervision <todo>” on the network
  • Using the Classroom A/V Computer
  • Using your own computer via HDMI at the Classroom A/V Computer Desk

Using the Chromecast is the simplest way to get started: Cast a Chrome tab or your Screen on your TV – Chromecast Help (

Turning on the Projector

To turn on the projector, locate the power icon and press this button once. The projector should beep, fans should start spinning, and the picture should appear after a brief warmup period (~30 seconds?).

Turning off the Projector

To turn off the projector, locate the power button. This button will need to be pressed twice with a brief pause between each press. The first button press will ask if you want to shut the projector off, and the second button process will start the shut-off process.

It may take some time for the fans to stop spinning to prevent damage to the hot bulb.

Selecting your input

Alternative heading: “Why is my device not appearing? Something seems to be!”

The Chromecast input and A/V Desk input are both connected to a Yamaha A/V Receiver located in the small closet on a shelf directly above the door. To change which input is being displayed, there is a remote left in the small closet. This remote will need to be pointed so the receiver can see it.

To change between the inputs, use the “Input” buttons (up/down) to select between the different inputs. It will take a moment for the receiver to switch after your selection has been made.

Be sure to put the remote back on the shelf (read: easily visible) in the closet.
