Ever wish you could track down Dragon Balls like Bulma or Goku? This is a fun, geeky little program that runs on a Raspberry Pi and mimics the Dragon Ball Radar from Dragon Ball Z — using Bluetooth signals instead of mystical energy.
When it detects a high number of unique Bluetooth MAC manufactures nearby (like in a busy area), it displays a number of Dragon Balls (1–7) on an LED matrix, just like the classic radar.
- Scan for nearby Bluetooth devices
- Count the number of unique MAC manufactures
- display between 1 and 7 Dragon Balls on an LED matrix
- once 7 unique MAC manufactures are found, a large dragon call appears, and then it resets
- Raspberry Pi (any model with Bluetooth should work)
- LED Matrix Display 8x8
- Python 3
- Bluetooth support (Pi Zero or better)
