-The roots of the Pop Neuron lies in the [[http://​solarbotics.net/​bftgu/​starting_nvnet_bicore.html|bicore]] oscillator used by the [[http://​solarbotics.net/​bftgu/​default.htm|BEAM]] (Biology, Electronics,​ Aesthetics, Mechanics) robotic group for their BEAMbots. ​Each Pop Neuron is one half of this circuit with the extra option to easily change the resistor-capacitor components. The bicore oscillator is a classic Schmitt-Trigger oscillator, with all components used twice.\\+The roots of the Pop Neuron lies in the [[http://​solarbotics.net/​bftgu/​starting_nvnet_bicore.html|bicore]] oscillator used by the [[http://​solarbotics.net/​bftgu/​default.htm|BEAM]] (Biology, Electronics,​ Aesthetics, Mechanics) robotic group for their BEAMbots. ​This bicore oscillator is a classic Schmitt-Trigger oscillator, with all components used twice.\\ 
 +With each Pop Neuron one can build one half of this circuit by plugging in the resistor-capacitor components to the board. \\

-Some characteristics of the Pop Neuron design are the use of "​pure"​ analog components. For example to avoid "​digital"​ [[https://​en.wikipedia.org/​wiki/​CMOS|CMOS]] chips in the analog computer Confetti the Schmitt-Trigger (respectively the inverting Schmitt-Trigger) is build out of [[https://​en.wikipedia.org/​wiki/​Operational_amplifier|OpAmps]] similar like the [[analog_computer:​confetti109_schmitt_trigger|Confetti Schmitt-Trigger]] and the [[analog_computer:​confetti110_inverting_schmitt_trigger|Confetti Inverting Schmitt-Trigger]] boards. ​And because there are actually two OpAmps ​build in the chip this also provides the option of an extra buffer circuit ​on the Pop Neuron board.\\+Some characteristics of the Pop Neuron design are the use of "​pure"​ analog components.

This second OpAmp is used as an extra input buffer circuit.\\
 The option to plug a Resistor-Capacitor-Circuit with different values in the sockets of the board - like used in many other designs of Confetti modules - makes the Pop Neuron more flexible to use in all kind of applications.\\ The option to plug a Resistor-Capacitor-Circuit with different values in the sockets of the board - like used in many other designs of Confetti modules - makes the Pop Neuron more flexible to use in all kind of applications.\\
 Thus one can use the Schmitt-Trigger in combination with the plug-in slots of the Pop Neuron module to create an analog neuron. In adding resistors and capacitors to it one can build an excitatory or an inhibitory neuron out of a Pop Neuron 001 module, depending on the jumper setting.\\ Thus one can use the Schmitt-Trigger in combination with the plug-in slots of the Pop Neuron module to create an analog neuron.

-The core ides of the analog computer Confetti was to provide a highly flexible system for using and combining all individual boards. One can patch all modules via a build in bus or in using the patching wires in combination with the sockets on the boards. With these ideas realized in the Pop Neuron, ​too one can easily use two different neurons to build an oscillator, or with some more neurons one can build a whole analog artificial network.\\+The core ides of the analog computer Confetti was to provide a highly flexible system for using and combining all individual boards ​of this system.

 These problems are solved with the design of the [[analog_computer:​confetti501_confetti_neuron|Confetti Neuron]] and the new board also comes with some more benefits like an extra output for the nice triangle wave that one can use for audio signals and the need of just one jumper to set the behavior from excitatory to inhibitory.\\ ​ These problems are solved with the design of the [[analog_computer:​confetti501_confetti_neuron|Confetti Neuron]] and the new board also comes with some more benefits like an extra output for the nice triangle wave that one can use for audio signals and the need of just one jumper to set the behavior from excitatory to inhibitory.\\ ​
