I had to do something to consistently inform everyone about the latest cases of COVID19.
We know that we can die anytime, even I can die while writing this post, after all, I me, you, we all are mortals. The whole world shook because of COVID19 pandemic. We know how to prevent this, but hey! we know how to pray and why to pray, do we do it daily? No!! Actually, we forget the root cause of why we should do things. So, we know that an hygienic lifestyle can save us yet we don't do it properly. Consider the case of my younger brother, he wants to go out and play even in this time. I had to do something to consistently inform everyone about the latest cases of COVID19. So, I made a digial desk display that shows the latest cases of COVID19 in real time. As this has a clock then I can put it in a place where everyone gathers or comes. They'll see the numbers add up, which will trigger awareness in them and hopefully everyone will be conscious.
Also as I am a maker and hobbyist, this turned out to be a good project to work on in this lock-down session.
1. Parts I have used:
- Raspberry Pi 3 Model B (booted using sd card)
- Raspberry Pi UPS module (optional)
- 7 inch HDMI LCD Screen
- HDMI to HDMI cable (this comes with the screen)
- USB cables
- 5v 2A power adapter (to power the pi)
- PVC sheet [wooden color] (to make the body)
2. Setup raspberry pi:
I guess you have set the pi up perfectly, unless you haven't -
- get an SD card - more than 8 GB
- download latest raspbian iso file from here.
- Burn the SD card using etcher
(Note that people can say a about other software which requires you to do some setup thingy but etcher is super easy to use and simple but effective too.)
Just plug your SD card to pc, run etcher, you'll see the SD card is automatically selected by etcher, then click to select the downloaded iso file or image, then burn it. After successful writing and processing unplug SD card and connect it to your pi, power it and VOILA!! It's alive.
3. Circuit Diagram:
Connect everythingup and power up the raspbery pi,
You'll see the pi booting.
You'll see the pi booting.
4. The Body:
I cut a PVC sheet to according to the display size, then added it using screws. After that I wired everything up. At last added another sheet at back to support it from falling (blue sheet). If everything is okay, you should see the pi booting (last picture).
5. The Software (Source Code):
If all set up perfectly, you'll need to install some libraries.
The program is written in python3. For GUI (Graphical User Interface) I used PyQt5, and to extract realtime COVID19 data I used COVID19Py library. Thanks to the guys who made the API available for us [[Kudos COVID19Py team]]. See doc in pypi.
That's pretty much it, now open up Terminal on raspberry pi and install libraries (copy each one of them and paste on rpi terminal).
Ignore $ sign while copying
$ pip3 install pyqt5
$ pip3 install requests $ pip3 install covid19py
That's it, now download the code from here, I've provided the code below:

6. Finish Up:
After testing the code I put it in desk and dedicated a power source for it. So that it can work while charging. By using the ups this can run even in load-shedding also, this gives ur pi SD card a suitable protection too.
No matter how or who we are, we have to die. Let's not think about yourself, think about the world. We can only live forever through our deeds, let it be that way.
Question do you use raspbian lite iso or raspbian desktop ? thank you
ReplyDeleteNo, I have used Rasbian-Stretch.
