Bored of blinky lights that blink in response to time?
Make them blink with space instead!
This instructable shows a quick method for connecting LED tree decorations to a Geiger counter via arduino, so that the lights blink between different strings each time radiation is detected.
It's nicer to think of this as "cosmic rays" than some of the other possibilities...
What you'll need:
- A Geiger counter with pulse output (I'm using the Gieger counter from MightyOhm)
- A few strings of battery-operated LED decorations (I'm using stars and snowflake decorations from Poundland, 'cos you gotta love dem luminous spheres of plasma and dem frozen supercooled cloud droplets)
- Arduino-based microcontroller (either a proper development board, or I'm using a stripboard bare bones version)
- Female header (two or three sockets' worth)
- Batteries/alternative power supply for your Geiger counter and Arduino
- Assortment of connecting wires (either jumper leads or multi-core stuff to solder)
- Soldering equipment, wire cutters, wire strippers etc.
- Maybe a spare LED for testing, insulation tape...
