Osziflap

========

A simple flappy bird clone developed during the mini game jam in the

"Künstlerhaus" in Dortmund on 2017-06-10 by Miriam, Marco, and

Reinhard. German 

[blogpost](https://blog.bakera.de/klein-aber-fein-der-minigamejam-in-dortmund.html)

about the event.

The game is played on a oscilloscope with a potentiometer

controlling the bird and a button to reset the game. It was developed

in about 8 hours. The analogue signal is generated by a R2R network

driven by some of the (digital) GPIO pins of a RaspberryPi 3.

Version 2 - Audiooutput

-----------------------

A second version uses the audio jack of the raspberry pi to produce an analog 

signal.

The connection is established via an audio to cinch adapter cable.
