Horizontal cylinder around the outer circumference of the rail + a safety margin // margins from edges h_margin = hole_dist_side*4; v_margin = hole_dist_top*2; Potentiometers: - One potentiometer per step, to set output voltages. (10 One potentiometer for internal clock rate. Switches: One SPST switch per step, to enable/disable gate per step. (10 One multi-pole rotary switch to disable reset (run once).
