This is my extremely compact and secure combination lock. It only has one single lever but allows for 33 million different combinations.
A more in dept video of this build will follow soon: In the video I will also show you how simple it is to set your own combination.

Color Description for all the circuits.
Limegreen Circuit : Controls the direction of the feed-tape and stops the feed-tape for a short while before restarting it again.
Lapis Lazuli Circuit : Sends a short pulse just before the feed-tape is about to start to start up again. The pulse is used to read the binary feed-tape. After it has read the tape it sends a binary output towards the decoder.
Light Grey Circuit : Whenever you stand on the pressure plate this line sends powers to activate the clock that the feedtape runs on. The power can be cut by the lime wire.
Purple Line Circuit : This is the toggle-able clock that gets activated by the grey line. It is a 4 tick clock with a 1 tick pulse. The signal gets split and send to directional input that can get toggled by the lime line.
Orange Line Circuit: Powers the counterclockwise movement of the feed-tape.
Yellow Line Circuit : Powers the clockwise movement of the feed-tape.
White Line Circuit : Distributes the output from the feed-tape towards all the different decoders.
Dark Green Line Circuit: Reads the direction feed-tape is spinning and turns it into a 1 or 0 state that also gets send into the decoders.
Black Circuit: These are the 5 decoders for the 5 hardwired ordersensitive input colors and directions. Each can read a 5 bit numbers giving 32 possibilities per input. So 5 inputs means 32x32x32x32x32 different combinations which is good for a total of 33.554.432 different combinations.
Magenta Circuit: This is the RS nor latch array. It is sequential meaning one latch can only be activated if the latch before it is activated. The Latch is setup in a way that it does not allow the same signal to be send into the same latch twice.
Pink Line: This is the reset circuit which resets all the latches is the magenta circuit.
Red Line: This is the override circuit. Whenever a latch isn't suppose to be activated but a decoder does have the right combination the red line overrides the decoder causing a reset signal to be send to all the latches.
Brown Line: This circuit is needed to allow for 00000 to be a possible number for the decoder. This line toggle the red circuit overriding any input in the decoder. Whenever the feed-tape gets read it unpowers briefly removing the override signal that the red circuit is sending into the decoder.
Light Blue Circuit: This is the last latch but is actually a t-flipflop. There wasn't any space for a latch. This flipflop when triggered overrides any signals coming from last decoder. So whatever color you enter at this point will reset the whole thing.
Cyan Circuit: This is the output of machine.

"Debug" is a term used for "Running" or simply "Testing a Device or System of any kind".
Anyway's, my point is, is that when you go to Run a Program in a Programing Engine, you have to Debug it before you can run it. Debugging is Very useful when your building something like this.
anyone with a great design?
I use to be on a PvP server where you protected your base/items with RedStone locks - I can't say that this is the 'Best Combo Lock', but it's defiantly original.
If you want to bring it a step further, you could make it a revolving combination lock. Meaning, every time you make an action (flip the lever), it changes the next combination in the sequence. You could then have another separate line of different colored blocks connected to pistons, and you'd have to decrypt it by calculating a pre-set algorithm according to the order of the pistons. This is a LOT harder than it sounds, but it's been done by a few RedStone geniuses on my old server.
Reason you'd do this is so it has a 'true number' of combinations - most locks are only compatible with allowing only 1 of the same combinations (for instance, using 'Purple' multiple times), meaning it doesn't give a true number of combinations. If you have a lock that can work like that - say you have 10 possible entries, and 5 actions to open the lock - you have 100,000 possible combinations. This makes it RIDICLOUS to even try to crack your lock - And you can't use any sort of "100% Guarantee Open Codes" (meaning, a VERY, VERY long code that you would use to open a lock that would open it no matter what if you were to enter it in the exact order... aka, say there was a 3 button lock, 3 combination. You'd use "123132213231321312" in that order, and it'd open no matter what.
But yeah, this is defiantly original, I <3 it.
But to be honest it seems very cool and things, but i don't get it? I never was in the redstone bit, but this is really awesome!
