BackNormal - 1k to U2-8 (AND NOT short to U2-10 Clock Rate - variable resist +6k between U2-8 and U2-9 Reset Sw - when pressed, short +12V and Reset In Pause CV In - ~27K to U3-8? No, transistors maybe activate? Outs: Clock Out - 1K to U3-7 From dcaec240831d28b722a7d7988287c76a1461e439 Mon Sep 17 00:00:00 2001 Subject: [PATCH] Gerbers .../precadsr_aux_Gerbers/precadsr-B_Cu.gbr | 518 .../precadsr_aux_Gerbers/precadsr-B_Mask.gbr | 185 .../precadsr_aux_Gerbers/precadsr-B_Paste.gbr | 15 .../precadsr_aux_Gerbers/precadsr-F_SilkS.gbr | 2066 .../precadsr_aux_Gerbers/precadsr-NPTH.drl | 4 | 100nF | Unpolarized capacitor | | | J7 | 1 | SW_3PDT_x3 | 3PDT miniature toggle switch // Note: don't mess with them.
