Ο Coffee Drip printer (coffee drop printer) is a strange machine created by the professor photos of RIT Mr. Ted Kinsman and can print your digital photos, but instead of uses expensive inks use some coffee.
The printer is powered by an Arduino microcontroller with 32KB memory, where you can store and print an approximately 80 × 100-pixel photo. The photos are low resolution but contain the drop quantity.
“The camera allows you to fully handle the height of the drip, the size of the drop, the distance between the drops, and the end of the paper used for photography. All of this affects the results of the image, ”says Mr. Kinsman.
In practice, however, the machine Coffee Drip printer accepts a low resolution image and converts it to Pixels. Each of the pixels corresponds with a number from 0 (point without even a drop) to 256 (the largest drop size). The size of each pixel is controlled by the microselector to determine how long space the drain valve will open. For example the darkest pixels require the valve to be open for 63 milliseconds. In this way, the machine can currently make 53 different shades of coffee. However, the results are impressive.
Scalable motors control the xy placement of the printer head on the paper to be printed.
The machine can use almost any liquid you want, but Mr. Kinsman chose coffee because of low price and availability. See below a video with this printer in action:
