Simple Combination Lock

Ok so for about an hour or more i have been adrift on this great site. actually stumbled here a few days ago and i really just havent left. I seen your Simple combination lock circuit and felt it had some things left ot be desired and you could expand on it more by adding a keypad that uses latches to hold the button information. so i did the circuit. here it is.


There is a guy somewhere on this forum he is looking for this information... i just cant find him again. he wanted to know if he could swap out the switches for something else in his paint ball scenarios...
