How does it work?

Look down.

The cost is cheaper than Raspberry Pi

The reason why I started the transformation was that I wanted to have a display tool hanging on the wall besides my mobile phone to remind myself of time, schedule, weather, etc. What day will the express arrive...etc.

Considering that the Kindle is cheaper than the Raspberry Pi, is based on the Linux operating system, is easy to crack and debug, and the ink screen is more naturally integrated into the home environment than the luminous screen, he decisively bought one online for $30. Second-hand Kindle 4, about 211.5 yuan.

But there are still three problems to be solved:

Kindle will automatically enter sleep state and display the saver;

If you want to update the screen Data, the browser page will be reloaded every time, and the look and feel is very poor;

Kindle browser also has some ugly and redundant elements, such as titles and URL bars, which are not good-looking;

Based on the above reasons, I designed a solution:

Deploy a server that can obtain screenshots of web pages, and let Kindle serve as the terminal display. Download the screenshot once every minute.

In view of the fact that some platforms on the market provide scheduled screenshot services, but the fees are not low, I decided to write a small server myself, use Puppeteer to take screenshots, and then rely on ImageMagick to convert the format.

With this plan, he started.

First set up the image server.

The little brother wrote the code himself and created a free account on Heroku. After filling in the project name on the platform, he can deploy it with one click. (Now open source, available to everyone, see the link at the end of the article)

Before exiting, don’t forget to write down the URL.

Continue to open the keyboard, enter ~usbNetwork, press Enter, wait a few seconds, then enter; debugOff, and press Enter.

Reconnect the computer. Open the command line on the desktop, enter ssh root@192.168.15.244 and press Enter. Then enter the default password - mario.

Enter the code below to create an image download script so that you can open and edit it.

nano /mnt/us/script.sh

Enter the following code in the editor. Pay attention to the "Insert_your_URL_from_step_2_here" part and replace it with the URL copied in the second step. ：

curl Insert_your_URL_from_step_2_here -o status.pngeips -ceips -ceips -g status.png

In the above code, the first line is to save the image to the status.png file , the two eips -c commands are to clear the screen, and the last line displays the image.

When finished, enter control-O, then control-X, save and exit the editor.

Then run the script to test, enter /script.sh, and you will see the image display on the screen.

The last step is to set the timer program to refresh every minute.

Since the Kindle system is the same as other Linux devices, there is a cron tool that can be run regularly according to the plan.

Just open the configuration file:

nano /etc/crontab/root

Add the following command to the bottom:

*****/mnt/us/script.sh

Similarly, enter ⌃O, press Enter, then enter ⌃X, and finally restart:

/etc/init.d/cron restart
