POV (Persistence of Vision) displays work by rapidly moving a set of LEDs or lights in a specific pattern while turning them on and off at precise intervals. This creates the illusion of a stable image or text because the human eye retains each light's position for a brief moment, blending the sequence of lights into a continuous visual. The timing and speed of movement are critical to achieving clear and legible visuals.
This particular POV display will have the following tentative specs:
- Hand-wave operated
- ADXL345 accelerometer to detect motion
- 5 front LEDs (probably white)
- 5 back LEDs (probably white)
- Padauk PFC232 Microcontroller to handle the logic
- SAO compatible so you can put it on your badge
- User can use the SAO to customize the display message via I2C
would be funny if it detects the badge falling and yelling "ahhhhhhhh" on the way down or something :D Cool project :)
