Online alarm clock for 1:21 am

As you hand the Derwent River shift to the next person, set the 1:21 am alarm for the moment they need to open the eel-trap gate. That leaves enough room before 2:00 am to explain the latch, water conditions and anything unusual you have noticed, without relying on a hurried verbal reminder.

With river noise, wind and a running ute nearby, the alarm volume deserves a quick check before the handover is complete. Raise the phone’s media volume, play a brief test and place it where the sound will not be muffled by a pocket, bag or cabin door. Keep this page active and the phone awake: if either is shut down, the eel-trap gate alarm cannot sound, and the opening may be missed. A separate backup alarm is sensible when another person is taking responsibility.

On a 1:21 am changeover beside the Derwent, darkness can make even a familiar gate awkward to identify. Set out a charged torch before the alarm time, aim any fixed work light towards the latch rather than across the other person’s sightline, and check that spare batteries are within reach. Keeping the light low while instructions are exchanged also helps preserve a clear view of the riverbank and footing.

Common questions

Does the alarm work if my laptop goes to sleep?

Not reliably. If the device sleeps or the screen locks, the browser tab pauses along with it, so the alarm may not fire on time or at all. Adjust your power settings if you're relying on this over a longer stretch.

Do I need to create an account or download anything?

No, there's nothing to sign up for and nothing to install. Pick a time and a sound, press Start, and it runs entirely in this browser tab.

Can I change the alarm sound?

Yes, there's a short list of tones to choose from before you press Start. Pick whichever one you're most likely to actually hear — softer sounds are easier to sleep through than a firm chime or bell.

What happens once the alarm goes off?

It rings through your device's speakers on a loop until you stop it from this page. There's no separate app notification, so make sure your volume is turned up before you rely on it.
