BackFrom below. Clock rate goes down when resistance goes up, opposite to expectation. C1 is too small for film; is film needed? More notes C10, C14 too small for film; is film needed? - Smaller cap (476nF?) for C1 - Ceramic 104s for C10, C14, might be fine, might introduce intermittents - Don't put R8 so close to R26 - D36/R47 too close Testing before powering up: Clock In - U1-13 (can get at from top when assembled - Stop Switch - 10 - center_adjust; center_col = width_mm/2; row_1 = v_margin+12; row_2 = row_1 + v_margin + 12; row_1 = v_margin+12; Initial stab at a charge no more than your cost of distribution to the * * 7.
