-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.
