Small device to interact with messenger.

The device prints pictures sent to a specific messenger bot. Then when you press the button, the device takes a picture and answers to the chat.

✔ TO DO

• Make the pi-camera promise work in code, instead of the ugly wait function
• Simplify and clean code
• Find working node librar for the thermal printer and remove the python library.
• Auto Remove pictures from local folder
• Better error management ( especially on the printer side )
• Rework chat interface to have options ( whatsapp, slack ...)
• Rework Camera to have different possible inputs ( reflex, webcams ... )
• Rework Print module to take into account different printers.
• Rework Tunnel to have different options (reverse SSH ... )

Setup

🎯 Ok now you will need to setup your hardware, that means the pi zero, the camera, the press button and the printer. I pretty much

👨‍🏭 Physical

Here you can view and download the 3D files.

I will export the CAM files as well later on.

👨‍🔧 Hardware

🎯 Ok now you will need to setup your hardware, that means the pi zero, the camera, the press button and the printer. I pretty much followed that Adafruit project so you can get inspired.

The Pi zero W

Get a micro SD card and etch the BerryLan debian image. ▶ It will allow you to setup your device easily on any wifi network through its bluetooth. COOL 👌

Cut a micro usb cable and cut it to so that you can solder the black and red cables to the power plug's + and -.

❗ Make sure you check which is + and which is - on you power supply.

❓ You can also power the PI through its pins, but I read that it bypasses some securities, so as I don't know much I wen through the USB.

Pi zero Camera

Just plug your raspberry pi zero camera. Then setup the camera in through sudo raspi-config. Reboot and it should be ready to use, you can check through raspistill -o test.jpg.

Button

Solder a wire from the Common pin of the button to the 3V3 of the PI. Solder a wire to the NO pin of the button to the pin 4 or BCM 23 of your PI.

❗ Add a 10K PullDown resistor between your pin and the ground.

Adafruit thermal printer

Simply plug the data cable to the PI's serial pins - G BCM14 BCM15 .

👍 Check on adafruit's project :

For the power input, solder the black and red cables to the power plug + and -, as with the pi cable.

❗ Make sure you check which is + and which is - on you power supply.
