Resistors light tweaks checkpoint after roughing out middle PCB Binary files /dev/null and b/VCO_MANUAL_v2.pdf differ 500k Trimpot; tune to 1V out HALF Dot1 Dot2 Dot3 Dot4 Dot5 Dot6 Dot7 Dot8 Dot9 Dot10 Dot11 Dot12 Dot13 W1 L2 <-- CV In - diode to U2-3 Clock In Normal - 1k to U2-8 (AND NOT short to U2-10 - Clock rate goes down when resistance goes up, opposite to expectation. Schematic fixes: Trim 5mm from vertical for both panels, to make fitting inside a case easier. Or 10mm if it can fit; losing the bodge area.
