Make the clock yours.

Pick its faces, how the seconds move, what the battery shows and how it chimes — then install it all over USB in one go. Your settings go from this page down the cable to the clock, and nowhere else.

01

Connect the clock

Plug the reTerminal E1001 into this computer with a USB-C cable and press Connect. The page reads what is on the clock; nothing is written until you choose to install.

While it is connected the clock pauses; Disconnect, or the end of an install, restarts it.

02

Name and Wi-Fi

The clock goes online for a few seconds now and then, to fetch the next hours of its face and check the time.

On its setup card, and its address on your network: clockbh.local

A second network optional — another place, or a phone's hotspot

No Wi-Fi yet? Leave it empty: the clock opens its own hotspot, clockbh-XXXX, with a setup page at http://192.168.4.1.

Faces

Tick the faces the keys go round — KEY1 next, KEY2 previous — and choose the one it starts on. The pictures are the faces as they are right now.

Motion and picture

How often the second hand moves. A digital face steps its seconds digits the same way; Minute means no second hand at all — the face changes once a minute, the quietest and longest-lasting.

On USB power, the seconds move every
On battery, every

Picture
Fetching the face

Each Wi-Fi visit brings this many minutes of the face, drawn ahead on clock.bh. Longer means fewer visits and a longer battery, but live data (weather, flights) gets older before the next visit. Faces with live data ask for less by themselves.

05

Battery

The gauge sits below the hub, where a watch shows its power reserve (on some faces, in a clear spot of the page). Drawn here in the panel's own pixels.

The gauge
The small line under it

The room's temperature and humidity come from the clock's own sensor (an SHT40 inside); the preview shows an example.

mAh

The E1001's own cell is 2000 mAh.

How long a full charge lasts

—

This is the clock's own estimate model, worked out the same way it does: what each tick, redraw and Wi-Fi visit costs, hour by hour through its day. The costs start as estimates for this board; on battery the clock compares them with its battery's real fall and learns as it goes, so the number under its gauge gets truer with time.

06

Sound

The clock has a small buzzer. Press ▶ to hear it here — the same square wave, pitch and pattern.

On the hour

The Casio chime is measured from a real F-91W: two ⅛-second beeps, ⅛ second apart.

Pitch

8192 Hz is the F-91W's real pitch — near the top of what some ears and laptop speakers manage.

Access and updates

The clock has a web page of its own: its status, these settings, and new firmware over Wi-Fi.

Its web page is open

With no Wi-Fi it opens its own hotspot for the page instead.
