The cutest Pomodoro timer in the world is also a clock hacker day

Students and hackers [prusteen] have recently fallen in love with the Pomodoro time management method. That is, you focus on your task for 25 minutes, then rest for 5 minutes, then repeat four times, and finally rest for a longer time. Initially, [prusteen] had been tracking on their phone, but hated to change the timer value between the Pomodoro and the break time. In order to keep the flow mode, [prusteen] came up with this cute little learning partner, who can do it all with the push of a button.

By default, this Pomodoro displays the current time. We think this is a convenient and often overlooked feature built by the Pomodoro timer. Press the momentary switch on the front and it starts counting up to 25 minutes. Then when the time is up, it will emit a stereo beep through a pair of buzzers and automatically start a five-minute rest timer. Press it again and the display will return to clock mode, although judging by the code, doing so will cancel the timer.

Inside the juicy shell are an Arduino Nano, an RTC and a 7-segment display. We like the attention to detail here, from the small green leaves on the top to the anatomically correct dimples on the bottom. We always like to see lids that are stuck with magnets. So satisfied. Check out the short demo after the break, unfortunately, it does not include any closing action.

Do you need to interact more with your Pomodoro timer? Build a pomo-dachi for yourself.

A clock without seconds is not a clock.

I kind of agree, but on the contrary, I don’t want things that should help focus to become busy and distracting. In fact, maybe it should have a gray code display to minimize changes.

Even better, there is a real vetinarii display: it only changes when you are not looking at it.

So what would you tell people to call things that tell the time but dare not care about the second? Time Machine?

I think it's not a hacker day without the gatekeeper in the comments.

@Kyle K said: "Then what would you tell people to call those things that tell the time but dare not care about the second?"

I will call them inaccurate and misleading. As a human being on earth, my time existence requires the minimum second resolution and ±3.5ppm accuracy, from -40°C to 85°C, updated at least once a day from the Stratum-1 specification source.

There are so many clocks with only one hour hand on European city squares.

The accuracy is ±3.5ppm (±0.302 seconds/day) ~ /-9 seconds/month. That is not so accurate.

For the time machine, you need more date numbers! For example, on October 26, 1985, you want to know whether you arrived before, during or after your departure.

No grumpy Hacker Day article is not a Hacker Day article

But (judging by the code), it does show the number of seconds in timer mode, which is when you want to avoid distractions. In addition/conversely, I want to see some indications of its position in the Pomodoro cycle (work, short or long rest, and how many Pomodoros before the next long rest), this is also possible (with settings The ability to use long press or other means to change the position in the loop) can help you restore it to the position in the loop after an accidental reset. (Actually, with the current code, it looks like it just alternates between 25 minutes and 5 minutes, and does not support long breaks at all, unless you implement them manually in the way you use the device, so you need to fix it first.)

A contrast filter is needed-I can barely see the display!

(My comments above are in response to Adrian Godwin, but sometimes appear at the highest level.)

Interesting; before that, I didn't know anything about the Pomodoro Technique. More in-depth exploration-excerpt [1]:

"The Pomodoro Technique is a time management method developed by Francesco Cirillo in the late 1980s. [2] It uses a timer to divide work into different time intervals, usually 25 minutes, with short breaks in between. Each interval has Known as the Pomodoro, it comes from the word "tomato" in Italian, named after the tomato-shaped kitchen timer Cirillo used as a student. [3]"

2. Cirillo, Francesco. Pomodoro Technique.

3. A Pomodoro kitchen timer, after which the method is named.

Seriously: this thing without a schematic is really annoying! It is not a trivial matter in a hardware project.

In fact, it is the idea of ​​automation that makes it worth writing. The details can be found in the code, but anyone who wants to make may use the parts they have to have on hand. Maybe the schematic will help, but it would be foolish to exclude the description due to lack of description.

The Youtube project is for focus only. It's not even worth the time to introduce them in HaD. LED clock projects cost a dime a dozen, so the loss is not big.
