Echo-Lalia might have built the world’s first E-ink tarot card reader, powered by a Waveshare RP2040-Plus board (Raspberry Pi Pico clone). At the push of a button, the Waveshare 3.7-inch E-ink display shows random tarot cards using random EM noise, complete with glitches to increase the digital-mysticism.
Everything is housed in a 3D-printed case with two switches, a button and a bone conduction transducer for sounds, all powered by 3 AAA batteries. Custom code is used to generate a random seed from the ADC pins, which uses an animation to visualize the noise that it is reading. There is a 25% chance to pull a card in reverse and a 5% chance of a random glitch happening.
- The lightest and most compact Kindle, now with a 300 ppi high-resolution display for sharp text and images.
- Read comfortably with a glare-free, paper-like display. The adjustable front light and dark mode make reading effortless, day and night.
- Get lost in your story. Tune out messages, emails, and social media with a distraction-free device specifically made for reading.
The glitches are coded-in sequences that modify the framebuffer images before sending them to the display. they include a horizontal or vertical tracking glitch, a color channel glitch, an ‘HSMB’ glitch which applies the wrong color data mode, resulting in a jittery look to the image, a ‘shift glitch where it duplicates and moves one part of the image randomly, and lastly a ‘negative’ glitch, where it inverts the image, but only if the card is already reversed,” said its creator.
