purpose
For my SAA-1099p clock fiddler (https://vanheusden.com/electronics/SAA1099-clock/ ) I needed something that generates a voltage between -5 and +5 V (with that voltage I can control the clock-rate of the SAA1099). This module allows me to do so.
schematics
explanation
Ehr..., well, the potmeter thingy produces 0...+5 V and the opamp (the triangles) together with the resistors in the right combination (those squares with 10k in them) shift and adjust this to -5...+5 V. Note that the opamp needs a negative and positive powersupply voltage for that (which eurorack gives you: -12 V and +12 V).
