===== PB107 Sync VCO II ==== That is a version of the [[paper_bits:pb101_syncvco|PB101 Sync VCO]] with a poti for shaping the waves. In square wave mode one can change the duty cycle and in triagle mode one can change the wave from triangle to ramp. ---- ====Schematic==== {{:paper_bits:pb107_sync_vco_ii_schematic_scan.jpg?400|}}\\ ---- ====Paper PCB==== {{:paper_bits:pb107_sync_vco_ii_11.jpg?400|}}\\ {{ :paper_bits:pb107_sync_vco_ii_11.ai.zip|}}\\ ---- ==== Parts ==== * **Resistors:** * 1x 1 kOhm * 1x 4.7 kOhm * 2x 3.9 kOhm * 4x 10 kOhm * 8x 47 kOhm * 4x 100 kOhm * **Capacitors:** * 1x 22 nF * 1x 10 nF * 2x 10µF * **Diodes:** * 1x 1N4148 * **Semiconductors** * 2x BC547 transistor * 2x LM358 OpAmp * **Mechanical:** * 2x IC socket, 8pins * 1x pin strip 1x14 * 2x pin header, female 90° 1x3, 1x2 * 2x pin header, male 90° 1x3, 1x2 * 4x jumpers * 1x mini switch * **Potentiometers:** * 2x 10k * 2x 50 * 1x 100k ---- ==== License ==== The PB107 Sync VCO II was designed by **Wolfgang Spahn** 2017-20.\\ It is licensed under a [[http://creativecommons.org/licenses/by-nc-sa/4.0/"|Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International License]].
