The tweiger counter
The following steps will enable you to build your own tweiger-counter! It searches in current twitter messages sent around the globe for the words like nuclear, calculates a sliding window average and pushes it to the arduino that will click for every incoming tweet like an original Geiger counter and will steer a servo as revmeter showing the current nuclear related posts on twitter. So the next time the twitter-verse is flooded by such tweets due to a new catastrophe you will be warned by an alarm of your tweiger-counter.
Step 1: Coding-up
get the code for the python script & the arduino sketch from github:
in the same folder as the python script create a text file called auth.txt where you OAuth data:
1st line: consumer key
2nd line: consumer secret
3rd line: access token
4th line: acess token secret
it will be read in by the script to connect the tweiger-counter
Step 2: Wiring-up
here is how you wire everything to the arduino. make sure you use the same pins or adapt the code.
Step 3: Suit up
to make your tweiger counter look nice, just grab some box to put it in and add a nice hand and scale. no exact instructions here, but maybe some insipration:
I just went to the locale tabacco shop, got an empty cigar box (shrinked it down a little since it was a bit oversized) and made a hand I mounted to the servo.
