Build Your Own ESP32 Instant Camera!

Want a Polaroid-style instant camera without the expensive refills? In this project, I show you how I built an ESP32-based instant camera that captures a photo and prints it instantly. Curious how it works? Watch the full build video below!


Why Build Your Own Instant Camera?

I’ve always loved the idea of a Polaroid camera, but the cost of refills (around £2 per photo) quickly put me off. So, I decided to build my own. While many DIY instant cameras use a Raspberry Pi, I wanted something simpler and cheaper. That’s where the ESP32 camera module came in a compact, affordable alternative with enough processing power to capture and print photos instantly.

What You Need
  • DFRobot ESP32 AI Camera Module A compact camera module with plenty of RAM for image capture.
  • DFRobot Thermal Printer For instant photo printing
  • 20V Drill Battery A reliable and portable power source
  • Voltage Step-Down Converter (Buck Converter) To safely power the ESP32 and printer
  • 3D-Printed Custom Enclosure Designed to house the components neatly.

How It Works

The ESP32 camera captures an image at the press of a button and immediately sends it to the thermal printer for printing. The camera and printer communicate via UART, and a buck converter ensures the 20V battery is safely stepped down to the required voltage.

I designed a custom 3D-printed enclosure to house everything neatly. The enclosure holds the camera, printer, and battery in a compact form, with a large button on the back for taking photos.

Overcoming Challenges
  • Printer Compatibility: I initially received a different printer version than expected, requiring me to adjust the baud rate and connection settings.
  • Image Quality: I implemented dithering techniques to improve the clarity of printed photos.
  • Power Management: Using a 20V battery required careful voltage regulation to prevent damaging the ESP32 and printer.
