-Each module can run one operation. It can be used for analog ​computing, designing synthesizer ​and all other kind of analog electronics.\\+The analog ​computer was key for the light and sound installation [[http://​wolfgang-spahn.de/​doku.php/​installation:​strangeattractors|Strange Attractors]] by Wolfgang Spahn where he "​calculated"​ a Lorenz System to modulate an other Lorenz System.\\

 +Confetti was the basic brick in the installation [[https://​dernulleffekt.de/​doku.php?​id=symbolic_grounding:​symbolic_grounding|Symbolic Grounding]] by Ch.Faubel and W.Spahn.\\
 +And it was the core of the Installation [[https://​wolfgang-spahn.de/​doku.php/​installation:​echo_state_networks|Echo State Network]], an analog neural synthesizer network build out of 150 Confetti Neurons.\\

 +=== Usage and Patching ===
 +Each module can run one operation, some boards together can be used for analog computing, designing synthesizer and all other kind of analog electronics.\\
 +For connecting the Confetti modules one can use the bus on all boards or just use patching wires. Certainly, a combination of both is possible. The connection boards are helpful for putting together a lot of boards.\\
 +
 +{{:​analog_computer:​entwicklung_lorenzsystem_atstudio_233642.jpg?​400|}}
 +
 +=== Chips ===
 The in- and outputs can be patched with normal breadboard patching wires. It's manly based on the operational amplifier TL072 and the operation voltage is 12V/-12V.\\ The in- and outputs can be patched with normal breadboard patching wires.

-The [[pop_neuron:​pop_neuron_main|Pop Neurons]] - one can build analog artificial neuron systems with these - are compatible to Confetti.\\ 
  
 +=== Acknowledge ===
 +The analog computer was inspired by the articel "Die Chaos-Maschine:​ Analoge Computer wiederentdecken"​ [[https://​www.elektormagazine.de/​magazine/​elektor-201109/​3939|Elector Magazine 09-10/​2011]] by Maarten H.
