===== Confetti704 Non Inverting Summer ===== The non inverting summer board for the [[analog_computer:analog_computer_main|Analog Computer Confetti]]. A good description of the basic functionality of the summer one can find here: [[https://www.electronics-tutorials.ws/opamp/opamp_4.html|The Summing Amplifier]].\\ The board has a jumper marked as V3 for using the sum of two (no jumper) or three inputs (set jumper) different inputs..\\ {{:analog_computer:confetti704_non_inverting_summer_osc_202153.jpg?600|}}\\ The screenshot of an oscilloscope: summing to different inputs together, a square wave plus a sine wave.\\ ---- ==== Paper PCB ==== {{:analog_computer:confetti704_non_inverting_summer_02.jpg?300|}}\\ {{ :analog_computer:confetti704_non_inverting_summer_02.zip |}}\\ ---- ==== Parts ==== * **Resistors:** * 1x 33.33 kOhm * 4x 100 kOhm * **Semiconductors** * 1x TL074 OpAmp * **Mechanical:** * 1x IC socket, 14pins * 1x 2 pin strip * 1x jumpers * 4x 2 pin header, female * 2x pin header, female 90° 1x3, 1x2 * 2x pin header, male 90° 1x3, 1x2 ---- ==== License ==== The Confetti704 Non Inverting Summer was designed by **Wolfgang Spahn** 2015-19.\\ It is licensed under a [[http://creativecommons.org/licenses/by-nc-sa/4.0/"|Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License]].
