BackOnly has A1Ms in orange. * Expensive, about $3 each. *** Replacing LEDs in many places might be fine, might introduce intermittents From c96644890cf0985bb0d02bb542ef75a0a00d53f2 Mon Sep 17 00:00:00 2001 Subject: [PATCH] Added hard sync to schematic, laid out PCB with exploratory 8hp layout Schematics/Enlarge/Enlarge.kicad_prl | 10 nF | Unpolarized capacitor | | | | Tayda | A-4349 | | J2 | 1 | TL074 | Quad operational amplifier, DIP-14 A-1135 2 8 pin DIP socket | | | Tayda | A-3588 | | R3, R21 | 2 jackHoleDepth = 10; // [1:1:84] square_out = [third_col, fourth_row, 0]; pwm_cv_lvl = [width_mm - h_margin - working_width/8, row_4, 0]; pwm_cv_lvl = [second_col, first_row, 0]; //Second row interface placement f_tune = [second_col, third_row, 0]; fm_in = [input_column - h_margin/2, row_1, 0]; fm_in = [input_column - h_margin/2, row_1, 0]; square_out = [width_mm-h_margin, row_1, 0]; square_out = [output_column, bottom_row, 0]; pwm_duty = [width_mm - h_margin - working_width/8, row_2, 0]; cv_2b_atten = [right_col, row_7, 0]; manual_1 = [left_col, row_6, 0]; cv_1b_atten = [right_col, row_5, 0]; audio_out_1 = [right_col, row_1, 0]; f_tune = [width_mm/2 - h_margin, top_row, 0]; f_tune = [h_margin+working_width/8, row_3, 0]; pwm_duty = [second_col, first_row, 0]; c_tune = [width_mm/2 + h_margin, top_row, 0]; f_tune = [second_col, second_row, 0]; //Third row interface placement fm_in = [first_col, third_row, 0]; fm_lvl = [h_margin+working_width/8, row_2, 0]; fm_lvl = [second_col, second_row, 0]; //Third row interface placement fm_in = [first_col, first_row, 0]; //Second row interface placement sync_in = [first_col, fifth_row, 0]; square_out = [third_col, fourth_row, 0]; triangle_out = [output_column, row_2, 0]; fm_lvl = [h_margin+working_width/8, row_3, 0]; left_rib_x = thickness * 1; //right_rib_x = width_mm - hole_dist_side, height - v_margin; working_increment = working_height / (8+tolerance/3); // generally-useful spacing amount for vertical columns of stuff col_left = h_margin; bottom_row = v_margin + 12; row_2 = working_increment*1 + row_1; row_3 = working_increment*2 + row_1; row_4 = row_3 + vertical_space/7; cv_in_1a = [left_col, row_7, 0]; cv_in_1b = [right_col, row_5, 0]; audio_out_1 = [right_col, row_3, 0]; cv_in_2b = [right_col, row_3, 0]; manual_2 = [left_col, row_1, 0]; fm_pot = [input_column - h_margin/2, bottom_row, 0]; c_tune = [width_mm/2 + h_margin, top_row, 0]; f_tune = [h_margin+working_width/8, row_3, 0]; pwm_duty = [second_col, first_row, 0]; c_tune = [width_mm/2 - h_margin, top_row, 0]; f_tune = [width_mm/2 - h_margin, top_row, 0]; f_tune = [width_mm/2 + h_margin, top_row, 0]; f_tune = [second_col, fifth_row, 0]; pwm_duty = [width_mm - h_margin - working_width/8, row_2, 0]; fm_lvl = [h_margin+working_width/8, row_4, 0]; left_rib_x = 0; // [0:No, 1:Yes] TaperAngle=asin(KnobHeight / (sqrt(pow(KnobHeight, 2.
