    Possible combinations with thirteen buttons

    This is similar to one of my previous posts, but is quite different. There are 13 buttons (numbered 1, 2, 3, ...13)in this combination lock, and you have to figure out which ones can be pressed in. They can either be pushed in or left into their original extended position. You don't know...

    How to calculate possible combinations of sets

    By the way, pressing the wrong buttons reinforces the lock. Each wrong button has a lock bar on it, sliding into the lock, making it stronger than before. :)

    How to calculate possible combinations of sets

    Thank you for the reply. I expected it would be an infinite answer. I've redesigned the lock. Same scenerio as before. 3 primary buttons, 11 secondary buttons. This time, the user is aware that each secondary button can only be pressed once, and order still does not matter. Choose 1...

    How to calculate possible combinations of sets

    Posts: 10 I am a woodworker, and am designing a two part magnetic/spring lock for my blanket chest. The first part has 3 master buttons (primary buttons A, B, C), and the second part has 11 secondary buttons (1, 2, 3, ...11). What you do first is choose 1 of the 3 master buttons that opens...

    Two-part problem; calculating possibilities of lock

    Thank you very much! That is not enough combination possibilities for me, so I need to raise the stakes a little bit. What if the user pushing the buttons didn't know they only had to push 1 master 3 secondary. In fact they don't know how many buttons had to be pushed in at all? The...

    Space saver compartments with mechanical crank device

    yes, I've made gears with the bandsaw, but now have all the templates to make a complete wooden clock. the corners will probably be rounded over with the router to make the directional change in the corners easier.

    Space saver compartments with mechanical crank device

    the purpose is to use as many compartments in one given space, and have them hidden, so only a couple are accessible at one time. the other purpose for the entire project is to use as many mechanical devices i can come up with and build them.

    Space saver compartments with mechanical crank device

    Greetings. I am a woodworker, and i build lockboxes with hidden compartments and complicated homemade magnetic locks. On my current lockbox, i am trying to design a "box of compartments", 16 compartments to be precise. included is a quick top view (looking down) design. there are actually 15...

    Where to find a schematic for a push-button combination cypher lock

    i don't care much for the electronic locks. the mechanical ones are the type I'm trying to duplicate. thanks for the idea about the clear paper.

    Where to find a schematic for a push-button combination cypher lock

    of course, i want the design as simple as possible, but just as effective as the push-button type lock. the easier the design, the less pain in the rear building it i am being creative, but there are so many moving parts in one of those locks, it's difficult to keep track of what-is-doing-what...

    Where to find a schematic for a push-button combination cypher lock

    im trying to build a cypher-type push-button non-electrical combination lock. the problem is there are no threads/schematics/drawings/specs/diagrams that actually instruct how the push button mechanics work. is there somewhere i could be looking for a schematic?

    Homemade cylinder/actuator push-button pin/tooth/spring mechanic lock

    i do have to include that this is just an early stage drawing. it is nothing more than an idea. the 4 'blocks' on the cylinder are nothing more than an example/idea. there would be many many more than 4. and they don't have to be blocks either. they could be triangular holes with teeth that...
