More robust and easier to adjust CV output range, switch between 5v and 2.5v max (or whatever is configured). - Momentary-normal-off pushbutton to manually reset. LEDs: One per step, to set output voltages. (10) One potentiometer for internal clock rate. - One SPDT switch to disable the clock, and a big board behind it.
