Electrical engineering student Sam Zeloof at Carnegie-Mellon retrofitted an old Polaroid Pronto! Camera with a Paspberry Pi Zero W board and thermal printer – the device learned to instantly print photos on receipt paper.
According to Zeloof, the main challenge was squeezing the board, thermal printer and two 3000mAh lithium-polymer batteries into the original case. He succeeded – the outwardly modernized Polaroid is almost indistinguishable from the original. The student even created a magnetic coil to easily replace a roll of thermal paper.
The camera will work up to 12 hours without recharging. A photo in monochrome and with a low resolution is instantly printed with a thermal printer, and a color copy of the file in high quality is saved to the card and can be transferred to another device via Wi-Fi.
The date of the photo is automatically added to the corner of the color image, and when you press the shutter button, a shutter sound is played through the 2.5 cm speaker.
