As usual do the lowest components first — resistors and diodes — then sockets, ceramic capacitors, power header, transistors, film caps, electrolytic caps... Something like that. Consider: 1 simple on/off switch/button/knob/etc. PSU \+12V, -12V and ground needed, probably up to 1amp https://www.youtube.com/watch?v=pQKN30Mzi2g - maybe not as efficient as a result of KiCad adding junctions during a component move. This needs to be distributed under the smaller board. #Kicad 7 # 2-layer, 1oz copper condition "A.Type == 'track' && B.Type == 'track'" main MK_VCO/Panels/luther_triangle_10hp.scad 359 lines width = 10; //knob_radius top_row = height - 25; // build up seven rows; middle one unused row_2 = row_1 + vertical_space/7; cv_in_1a = [left_col, row_1, 0]; left_rib_x = thickness + 6 + tolerance; rotate_vector_cos = 0.94; // 'x' of 20 degree rotation rotate_vector_sin = 0.34; // 'y' of rotation left_edge = -rotate_vector_sin * rail_depth; right_edge = height - v_margin; working_increment = working_height / 7; // Number of faces.
