parts substitutions.\u00a0 I used my stock of 1% resistors instead of the ones supplied.\u00a0 I decided to socket the three op amps.\u00a0 And I used a keyed, shrouded power header.<\/p>\n<p>The most important substitution was to use polystyrene capacitors for the 330pf instead of the supplied ceramics.\u00a0 I could only do one, which enabled a comparison.\u00a0 The filter with the polystyrene capacitors has much better definition and sound.\u00a0 I will replace the ceramics in the other one.<\/p>\n<p>For my own edification I drew out a schematic diagram, prior to starting the build.\u00a0 That helped me to double check all the parts and to understand the circuit to some extent.\u00a0 It it a very clever digital-analog design, with control inputs all having safety protection and outputs all buffered.\u00a0 I&#8217;m not including the schematics, since Eowave didn&#8217;t publish them.<\/p>\n<h3>Summary<\/h3>\n<p>Weather Drones is a very cool collection of synthesizer modules in a small package.\u00a0 It could be a nice entry point into modular synthesizers for a DIY builder.\u00a0 Here I&#8217;ve put both of them into a Pittsburgh Modular DC Cell-48 box.<\/p>\n\n\n<figure
