how to make thermal printer using crafts at your home
Some ideas and experiments can be dangerous. And for that you don't risk and damage your self and the environment, I am a professional in my business with a lot of experience! Every video, even that is completed with compliance with the all safety measures. Enjoy the video and eat the chocolate.
WARNING:
This video is for demonstration and education purposes only. Each demonstration presents risks and hazards that must be fully understood before attempting. And should be performed only by professionals.
Do you miss your old Polaroid instant camera, or your old Gameboy Classic's black and white camera? So do we, when we feel really nostalgic! In this Instructable, we will show you how to make your own instant camera using a Raspberry Pi, a Pi camera and screen and some electronics and a bunch of cardboard!.
For this project, we will be using a Raspberry Pi we prepared using our previous tutorial. If you’re starting from scratch, it’s a great way to make sure we are using roughly the same setup!
Feel free to setup your Raspberry Pi with this guide then come back here to continue with our Thermal Printer Camera project!
TIP - There are BIG changes happening for the Raspberry OS these days! As we write this update to this project, Raspberry OS "Bullseye" has introduced a lot of important changes for the Raspberry Pi camera module. We will update this project for Bullseye as soon as possible but in the meantime, we temporarily recommend you use Raspberry Pi OS "Buster" for this project to save yourself a lot of compatibility trouble. There are important risks to running older versions of an operating system, so make sure to install all the available updates as soon as possible!
We designed a cardboard frame so we can easily move our camera where we need it - for example, if you need better lighting or to take it to an event.
You can download the vector files for laser cutting from Github, or you can use it as a guide to cut your own with an X-acto blade or a box cutter. For this Instructable, we will assume you’re using our cardboard frame!
Open your touchscreen box and check that you have:
your video cable
your mounting screws
your DuPont cables
your touchscreen
If you have everything, you're ready to go!
Connect the red DuPont cable on the 5V pin on the screen board
Connect the black DuPont cable on the Ground pin on the screen board
Sit your Pi on top of the posts on your touchscreen
Screw your Pi in place
Connect the red DuPont cable to a 5V pin, and the black DuPont cable to a Ground pin on your Pi
Power your screen and your Pi through the microUSB port on your screen. If everything went well, the Pi and Screen should both turn on!
When you're happy that everything seems to work correctly, turn everything off and unplug your Raspberry Pi power supply.
TIP - The Pi camera module is one of the most sensitive pieces of electronics we’ve worked with and we have seen some get fried just because of static electricity. Touch something big and metallic in the MakerSpace or around your home to ground yourself, like one of the laser cutter, a dishwasher or a fridge!
Open your Pi camera module box and check that you have:
your Pi camera module
your Pi camera cable
If you do, great! Time to connect the camera module to your Pi:
Gently pull up the brown tab on the camera module's port
Insert the end of your cable all the way into the port, silver contacts of the cable against the contacts in the port
Push the tab back down to secure the cable in place
Gently pull the camera port's brown tab up on your Pi
Insert the other end of the camera cable inside the port, silver contacts turned towards the screen port on the Pi
Push the camera port's brown tab back down to secure the camera cable in place
Finally, secure the Pi camera module in the cardboard frame from the back with a piece of duct tape.
Now let's take a look at the button that will let us take pictures!
Your button
A couple of DuPont cables or wires
These buttons often have four pins. If you don’t know which pins are connected to the switch in the button, use a multimeter’s continuity mode to identify which pins are connected when you press the button! These big buttons are designed with arcade machines in mind, so the other pins are often reserved for an LED in the button to light up.
After you identified the switch's pins, turn on your soldering iron and:
Tin the switch pins with a little solder
Strip and prep some wires the same way you did for your printer’s power wires, this time using some DuPont wires (or regular wires, in case you just want to solder everything on your Pi’s pins)
Solder your wires to your switch’s pins
Feed your switch through the hole on your cardboard frame, wires first. Secure your switch from the back with the screw ring, but not all the way
Connect the black DuPont cable to a Ground pin on the Raspberry Pi, and the other cable to your Pi’s GPIO 16 pin - with the GPIO pins closer to you, that will be the third pin from the left
TIP - If the pin numbers on the Raspberry Pi seem confusing and you can't remember which is where...Don't worry, neither can we! That's why we use that handy Raspberry Pi GPIO pins reference from Pinout.xyz all the time. They also have pins reference for many, many other popular electronic boards!
Now that we took care of most of the hardware for this project, let's work a little more on the software side of things - starting with the thermal printer!
Before starting, check that your thermal printer is connected to the Raspberry Pi with its USB cable, and plug in the power supply for the printer before turning on your Raspberry Pi.
TIP - We are only covering installing your printer over USB in this tutorial, but it is actually possible to connect it over a serial connection as well. If that's what you would like to do, make sure to turn off the connection over the Serial port in the Interfaces section of the Raspberry Pi Configuration tool! Fail to do that, and your thermal printer will constantly spit out gibberish on paper.
