Self organizing blinker

Self organizing blinker

Ever wondered how can hundreds of fish or birds follow the same rout without crashing into each other? The answer is: interaction with the closest members, based on this algorithm several complex mathematical models were developed, using neuronal networks and other complicated solutions. The project presented doesn’t rely on any complex model, but the result is astonishing, each device interacts with its neighbors and after a while they synchronize each other to the same blink pattern.

You only need one rgb led, light sensor and Attiny13 the led is mounted into a ping-pong ball to diffuse the light, the pcb’s can be connected into a stream.

This is one of my favorite projects, because its simple to replicate, and the effects are very complex, basically this is a neuronal network regardless of the start up blink pattern in the end they will get synchronized. After settling you can interfere with any light source to disturb the system.

Music Blinking LED’s

Yeah you know what im talking about, you’re listening to your favorite tunes, and you would like some light to blink on the rhythm, i mean who doesn’t ? 🙂 We’ve all been trough this phase. So what can you do ? well the solution its pretty simple you solder a transistor together with a switch, some LED’s and a stereo jack connector and its done. Yeah its for beginners. Here is the parts list:

  • 4 LEDs (any collor)
  • P2 plug
  • 2 position switch
  • TIP31 component
  • Box to put all the stuff (if you want)
  • Soldering iron and accessories
  • Cable

Here is the schematic:
