The end of my pantry goes under the stairs to the second floor.  I HATE wasting valuable storage space so I decided to make good use of it by adding a wine rack.

Of course that wasn't good enough, and in true Myst fashion, decided to make a Puzzle Lock to hide a secret compartment.

I apologize for pictures only in the write-up.  I tried uploading videos of this in action, but they didn't upload.

I hope you enjoy my project.  Some parts are over the top possibly, but lots of good ideas in here I think!

Step 1: Secret Revealed!

When the correct lever combination is set, you can now push the button in the middle of the levers causing the wine cabinet to slide backwards and reveal a hidden compartment.

<p>NICE!!! </p><p>I see a few extra combination suggestions to make this more secure, since currently it wouldn't take long to try all combos, but I would suggest:</p><p>Changing the L- joint for a gear and teeth; so that rotating the knob would move the pin left or right instead!</p><p>This could be added to the current design even after being built, would give way more combinations. And has the added bonus that it could be changed (lift gear, slide pin, drop gear) in case anyone works it out by watching you!</p><p>Obviously add numbers/symbols round the knobs as your code :-)</p><p>Just a thought, great as is though.</p>
<p>That is an interesting idea! I like the thought of using gears and teeth. It might be tough to do this with wood, which is what I wanted to do for this puzzle, but I can see the possibilities for making more combinations.</p><p>hmmm... you could effectively use just 1 knob to change several pins too it slid out and back. Ok, something to think about. I like that!</p><p>I wasn't too worried about the number of combinations because you also had to discover the 4th position on one of the knobs in order to open the lock. If you don't unscrew the knob and move it to the other post, you will never get the combination. For the purpose of this project, it get's you to think about the puzzle and not just try all combinations...it drove my son nuts, because he tried to solve it by trying all combinations but it didn't work. Gotta move the one knob...</p>
<p>Excellent!</p>
<p>I need to find an Intructable Geek for a husband! I can't even figure out how to upload my pic in the box to the left. </p>
<p>Are you, or were you ever an employee of Krolmeister? If not, you would do well to seek employment with them.</p>
<p>LOL. Krolmeister? Maybe I should be, but I am not. My daughter used to like playing those Nancy Drew games. They were more of my inspiration than Myst, but if I referenced, &quot;Her Interactive&quot; I figured less people would know what I was talking aboutt. Good sleuthing to know this is similar to those games!</p>
<p>TracRat, you have amazing concentration, dedication, creativity, and excellent craftsmanship. Thanks so much for sharing this 'ible. My sister and I have just found flummox, an upstate NY geocache (GC62EK5), a codex-sort of thing that took us well over half an hour to open. Seeing that and then reading your detailed Instructable is increasingly leading me toward building some of my own. Thanks for sharing your work!</p>
In another lifetime, you were a secret agent:
<p>This is such an excellent idea, Casey! My wife and I love the Myst series (must play them again, soon) and have made a few projects along their themes, over the years. Seeing your implementation of a hidden cabinet with all the elements of a typical Myst puzzle has persuaded me to do something similar. </p><p>I came here looking for ideas to build a puzzle lock for a side door on a new garage I'm building (I hate having to fetch a remote or keys if I'm already in the garden and want to pop in to my workshop or the garage). I usually install my own electronic locks with a keyboard - but I have also made a puzzle lock for a gate that I needed to be able to open without electrics. </p><p>When I retired, I treated myself to a decent-sized laser cutter, so I am able to make quite high-precision parts. If I do use your idea for my garage lock, I'll come back here and let you know.</p><p>Well done - and thanks for publishing your project. I feel guilty for not having the patience to document any of my projects as an instructable. I'm so glad that you did!</p>
<p>Mike,</p><p>Thanks for the nice comments! I have a few long term projects planned that involve electronic locks, but if I have the time, I always prefer a mechanical solution. Using your laser cutter would certainly improve and perfect pieces for a lock. I spent a lot of time fitting and refitting parts because I was using hand tools.</p><p>Please, let me know if you make a lock based off of this. I would be interested in seeing what modifications you come up with.</p><p>As for posting instructables, the easiest way to get started is to take pictures with your phone as you create a project. I have several projects I have photo documented but later decided not to publish. It it easy to make an Instructable as long as you have pictures! I have also found that you can get a lot of the detail pictures of parts right before final assembly, so if you missed some things, you can get caught up. Anyway, thanks again! I have enjoyed sharing this idea and always welcome comments!</p><p>TracRat</p>
The locks, combinations, the colored leaves, wow.. just the way you thought about everything is so amusing to me, i bet theres a lot of other things everyday things and wisdom and other cool stuff that people around you are blessed to have.. a regular conversation about little things would probably still be amusing to me. You are cool!!! Im a fan....
Thanks! Sorry for this delayed reply, I just saw that you had made those nice comments! Well, the details were important to me. In a project like this, I wanted everything to have a reason for being there.<br>[delete]
<p>Very cool! I love the nearly-all-woodwork approach. It is functional art, the best kind.</p><p>When it was mentioned in the comments about more combinations, and the limitations you mentioned, I had an idea for that: why not have an upper channel as well? 3 more knobs in-between the existing ones. The lock becomes a sandwich with 7 variables, of 3 or 4 positions, so over 2000 combinations. (3^7+)</p><p>Of course the downside is you don't get to see the woodwork, as all the complexity is hidden between the plywood sandwich. Not as fun to show off.</p><p>Great work!</p>
That is not a bad idea about using an upper level for the knobs to get more combinations. You would definitely add complexity!<br><br>I think my woodworking was decent for this, but I was worried that if it jammed, I wanted to get to it. <br><br>I agree about not being able to look at it anymore either. I like to watch it operate.<br><br>Thanks for thinking of some options to make it better! I still have some spaces left in the house. I have some beginning ideas for the front stairs...
Plexiglass panel instead of plywood?

Wow i love the way you thought about everything and actually made it. I have lots of ideas too but i just dont have the means, time, or money to actually make it. But you did and... wow... just wow... good job.
this reminds me of one of those room escape games
<p>Can you build me the locking panel?? </p>
<p>I'm flattered that you like this so much! I'm not sure I could build everything the way you need as it has some pretty tight tolerances to work in a particular space. What did you want to do with the panel? Would it be for a similar use?</p>
<p>Amazing!!! I want one!!!</p>
<p>EPIC!!!!</p>
<p>This is really brilliant, and terrific in both design and execution. I will likely try to adapt this in a smaller scale for a project I'm working on as a present for my wife. </p><p>A question about the release mechanism. Pushing the square button/panel pulls the internal blocks inward, which then allows the door closer to pull the whole thing back. Does it pull fast enough that the user is surprised by the box moving by itself? Or does it seem like one is pushing the cabinet inward with the square button?</p>
this is absolutely amazing! I don't have the wood crafting skills to pull this off but I HAD to see how you did it and at first I was like &quot;OK push the button big whoop?&quot; then I saw the combination rods and was intrigued so I read on and I see now how you did it and my friend you are one smart cookie to come up with something of this complexity using wood AND keeping it beautifully done at the same time, I tip my thinking cap to you my friend I'm still in awe over this.
Holy wine rack batman! To the batcave!..... ummm batman.... I think your cave shrunk....
<p>Does the vibration of moving upset the wine at all?</p>
<p>Not really. The commercial door closer I use is very smooth and has a 2 stage closer. I had to even set it to be a bit firm at the end of opening to make sure it struck the light switch for the compartment properly.</p><p>Th only thing you have to be careful of is when you pull the rack back forward to re-engage the lock. I was to busy trying to get a satisfying &quot;thunk&quot; sound when it closed and I launched a bottle from the top shelf. All the other 30 or so stayed, but this one had a slick plastic label. Oops. all it did though was break the seal and we had to drink it...</p>
<p>Excellent!!!<br>Nice work! Love it! One of the better projects I've seen here in a while. Even better that it doesn't some how incorporate a frigging Arduino. I also like that you did it all with wood, which I think is a bit more challenging than using metal fab.</p><p>Only thing I might do different is, find a way to hide the grooves from showing. Actually, I'd give it more chances to be wrong too, by making more combinations possible. Maybe make the knobs plungers (Push-Pull) connected to the notched (Keyed) sliders using levers like the locking (Dead-Bolt) mechanism. Thus giving each knob three possible choices (2 wrong &amp; 1 right) or even more, depending on how complex you choose to make it. For example, if all knobs are at rest in Middle position, your left with decision to push or pull each one. This greatly increases the chance of getting the combo wrong. But that's just my opinion.<br><br>Oh! &amp; Nothing is over the top if it serves a purpose.<br>Regards...</p>
<p>Thanks for the thoughtful comments. I did struggle with deciding if there were enough combinations with my plan. What I found was that to add more positions for each lever caused 2 problems: #1 the grooves that the levers slide in started getting large&hellip;it is tough to keep the width the size I used and not crowd the panel. The second issue is that the knobs will start to bump into each other if you make them too wide. What if one lever is all the way left and the other is all the way to the right? I used the flat disk behind the balls in order to cover the groove when they were centered. You don't see the grooves when you zero out the combination.</p><p>I added the twist to the blue knob in order to remove any guesswork. It looks like a made a typo in my write-up. you must unscrew the blue ball from the right most fork and screw it into the one to the left in order to set the blue ball properly. At any given time, the blue ball can only be moved left right or center. But in reality there are 4 spots it can move. The trim is tough to see in my picture but it definitely confused the kids for awhile. (I hid video games in there as a prize for opening the compartment.)</p><p>Oh, the distance between each spot the lever can sit is mostly determined by the width of the push bar. If I had made this thinner, then I could have fit more combinations in&hellip; but it is all a compromise because then that part of the system would be weaker&hellip;</p><p>The wood made it immensely more challenging. If I could have used some metal gears or rods, I could have made it incredibly complex. I tried to use wood everywhere but there were a few spots that were just impractical to not use metal. Like the spring or the threaded rods (which are used to create the blue knob twist).</p><p>I thought this through for a year before I started to build it. It was basically built in my mind before I started my first cut. I was very happy that I had to make very few on the fly changes to my design. It got me through a period of having a tough time sleeping at night. I would think through each step and memorize how the next piece of wood would have to move. I guess it was more than just a project for me.</p><p>Everyone's response has made this so worthwhile to share. Thank you.</p>
<p>I wonder how the rest of your house looks. VERY creative...love it.</p>
I like it. I hope you can see the lock itself once the door is open, it shouldn't be hidden away!
<p>Stoning fantastic!!!!</p>
<p>THis is beautiful!</p>
<p>Keeper Of The Keys.</p>
this is amazing. what a clever idea. I want secret doors/spaces everywhere now.
<p>Than is so darn cool.</p>
<p>Thank you all for the encouraging comments! I am amazed with the number of views, favorites and followers. I clearly need to come up with more projects to share. You all motivate me!</p><p>If you have a chance, please vote for me in the Secret Doors and Compartments contest if you think this entry is worthy!</p>
<p>Beautiful!</p>
<p>Beautiful work! Saw you on Hackaday.</p>
<p>Loved to play Myst and definitely love this project. The idea is great and the execution is really nice.</p>
Wow! (wow seems good enough but the app won't let me submit without more words. :) )
<p>Awesome</p>
<p>That's awesome. It takes me back...</p>
<p>LOL. I like the music idea. I do have a light that turns on when the wine rack moves all the way back. I'll have to work on the music thing...</p>
<p>Very nice! Maybe a light would turn on and a sound played when button is pushed with right combo is entered. </p>
<p>Thanks for the comments! It took about a year of thinking to figure out how to make this.</p><p>The best part, which doesn't show in the pictures, is the EXTREMELY satisfying *CLUNK* sound that it makes when the button goes in all the way and the wooden locking bars retract. </p><p>I tried putting up video of it working, but had issues with the upload. If I can figure it out, I will try to post it soon.</p>
<p>Respect for the locksmith.</p>
Very nice! It most definitely is a tip of the hat to Myst, with the sliding knobs, large decorative push button release and all the clues to unlocking the door hidden in plane sight! This Instructable makes me want to create a similar locking small box! ...wheels are turning... <br>Great Instructable! Thanks for the post!
