Calyraen
It drives the interactive panel, signs a teacher in with a tap of their staff card, and casts the board to every student device. It holds up through six lessons a day with no fan and no reboot, and nothing to fail in front of a class.
The first five minutes of a lesson go to the machine. You wake a tired tower, wait on a login that thinks about it, and hunt for the cable that drives the panel. Then the board sleeps in the middle of an explanation. The cast to the tablets drops the moment the room fills up. A fan whines under the desk all winter and gives out in July. Every one of those is a period a teacher loses to a computer that was never built for a classroom.
A room needs the opposite. A machine that wakes in seconds, knows the teacher by their staff card, throws the board to thirty devices without a stutter, and has no fan and no spinning disk to fail in front of a class. That is a purpose-built workstation, not a recycled office box.
Driving the room, casting to the class, knowing the teacher, and staying up all day. Open each one for what it does and how far it goes.
A single link kit carries 4K video to the interactive panel at 60 Hz over HDMI 2.1, and hands the panel's touch and pen back as a standard USB device. Annotation lands where the teacher taps, with no calibration ritual first. HDMI-CEC wakes and sleeps the panel along with the workstation, so one press of the sign-in reader brings the whole front of the room to life. No second remote, no hunting for the right input. The same kit drives 65, 75 and 86 inch panels.
The workstation broadcasts the board to student laptops and tablets over the school network, up to 35 in a class, so the pupil at the back reads the same screen as the pupil at the front. It receives too. A pupil can cast their own work up to the panel with Miracast or Google Cast for the room to mark together. Frames land in under a second on Wi-Fi 6, and the stream drops its resolution before it drops the picture. It all runs on the school LAN, so a lesson never routes through the public internet.
A teacher taps their existing MIFARE DESFire staff card on the reader and is signed in to their own desktop, files and bookmarks in under three seconds, in whatever room they are teaching that period. The profile roams from the directory, so cover staff and specialists who move between rooms get their own setup on any workstation instead of a shared generic login. A PIN is there for the day a card is left in a coat. Sign-out happens on its own after a timeout or a second tap, so the next class never inherits an open mailbox.
The chassis is a sealed fanless mini PC. There is no fan to clog with chalk dust and no hard disk to fail. Heat leaves through the case, so it stays silent through a full timetable and a warm summer classroom. Storage is M.2 NVMe, so wake and file open are near instant and a knock to the panel jolts nothing. It mounts to a VESA 100 bracket behind the display, off the desk and out of reach of the class. All-day running is the design point, not a burst rating.
Every part is chosen and integrated to run a classroom from the board out.
A sealed fanless mini PC with M.2 NVMe storage, TPM 2.0 and full drive encryption, 2.5 GbE and Wi-Fi 6. It runs CalyOS Desktop under a whole-school management profile.
HDMI 2.1 video to the interactive panel, with USB touch returned as HID and HDMI-CEC power sync. One bundled cable set, sized for a wall-mounted display.
A small USB desk reader that takes the school's existing MIFARE DESFire staff cards for tap sign-in. It has a PIN pad fallback and a status LED the class can read from their seats.
Screen broadcast to student devices, live thumbnails of every screen, lock and blank, push a link or a file, and receive a pupil's cast to the panel. All of it over the school LAN.
A steel bracket that hangs the workstation on the display's VESA 100 pattern, cable-managed and out of reach, so nothing sits on the teaching desk.
Between lessons the workstation sits in standby rather than fully off, so a tap on the reader brings it and the panel up in under eight seconds. Nothing spins up and nothing boots from cold between periods. Overnight it patches and sleeps, so the first teacher of the day meets a machine that is ready, not one still thinking about updates. Modern standby is set in the management profile, so it works the same on every machine and is never left to chance.
Heat leaves the sealed aluminium case by conduction, so there is no fan pulling chalk dust and paper fibres through the machine and no bearing to wear out mid-year. That matters in a room where a teacher is talking over it. The M.2 NVMe drive has nothing to spin, so it shrugs off a knocked panel and opens a large slide deck without a stall. Fewer moving parts means fewer call-outs.
Yes. The reader takes your existing MIFARE DESFire staff cards, so nobody has to carry a second card. For the day a card is left in a coat, there is a PIN pad on the reader.
No. Broadcast and class control run on the school LAN, so a lesson never leaves the building. If the network gets busy, the stream drops its resolution before it drops the picture.
The same link kit drives 65, 75 and 86 inch interactive panels, over a single bundled cable set.
On a VESA 100 bracket behind the display, cable-managed and out of reach. Nothing sits on the teaching desk.
It waits in standby and wakes with the panel in under eight seconds on a tap. Updates install overnight, so the first class of the day never waits on one.
“A lesson should start when the teacher taps in, not four minutes later when the machine finally catches up. We build the workstation so the first minutes of a class go to the class.”
