It's like a keypad, enter the wrong button order. So let's say there are 4 buttons. 1 2 3 4.
Enter the numbers in a specific order, and it does something. It took a lot of space to build in the original. I remember a lot of the schematics from old projects but can't get around building it because of time.
It took a few weeks for the inventor to make it work smoothly. It has to be in a specific order of numbers to activate what ever. Took up 3 quarters of the page I think.
Ok, im also on it, and i have to say it looks pretty promising up until now. Im still trying to make it so the code has to be typed in a predetermined order. Iam also using a binary-bus to make it not quiet so obvious what the code is ^^.
Oh and basicly all of my logic stuff is blatantly stolen from erwins_cat, who helped me ALOT(...well....) so far. ^^ Its a quiet challanging contraption sofar, i hope i have it running by tomorrow.
