![]() A differentiated sharp high pulse through C-R combination of C4-R5 is applied to reset pin 15 of IC2 to reset the output to ‘0’ for a fraction of a pulse period (which is not visible on the 7-segment display). Thus, if the clock stops at seventh count, the display will read zero. There is a probability of one chance in seven that display would show ‘0.’ In such a situation, the concerned player is given another chance until the display is non-zero. Although it is quite feasible to inhibit display of ‘0’ and advance the counter by ‘1’, the same makes the circuit some what complex and therefore such a modification has not been attempted.įeel interested?

After applying the Press-n-Peel to a blank PC Board, I use a standard A4 laminator to transfer the toner from the Press-n-Peel to the PC Board. ![]()
