3d puzzles

Hey guys, I have a couple of really cool puzzle designs that are printable. And I'm thinking of opening an online shop to sell just the designs. What price would be reasonable for a game/art design? And would you ever Buy a design? And if so, what price would you pay for a relatively simple design? What would you be willing to pay for an intricate design? I know thingiverse is awesome, and open source is the way to go. Though currently I'm a poor college student who's playing around with some 3d designs Trying to see if I can earn some extra money here and there. Thanks your help guys, -Tom

Challenge: K'nex Puzzle Box

Hey guys, so I've been looking around at some of these cool wooden puzzle boxes on instructables and being a member of the k'nex community I immediately thought that it would be really cool if a knex puzzle box could be made. So I present this challenge, try to make a puzzle box out of knex that requires some kind of trick to open (see this link to get an idea of what I'm talking about). Try to make the box as small as possible but size doesn't really matter. Good luck and I will be trying to make one too so I will post my progress as updates to this thread. Thanks.

There are more.

Most puzzles on instructables that I've found have been common 3x3x3's, and maybe a magnetic 2x2x2 :):) (courtesy of burzvingion). Does anybody know that there are like... BILLIONS of other types of twisty puzzles? I'll upload some pics of examples. any questions of what they are and I'll answer them.

What do you think about puzzle boxes

What are your thoughts about puzzle boxes? Do you like them, what do you think is important in one, the looks, the mechanism, the amount of moves, innovative tricks and moves, the type of wood, the size, etc. What are your general thoughts about them, what do know about the inside of them (how there build, etc)??? What is a puzzle box A puzzle box is a box that requires certain moves/tricks to open it, you could say it's somewhat like a safe. Normally these moves a very hard to see and even harder to know. These things are like the improved version of a secret compartment. In my opinion a puzzle box should at least have 8 moves. Some puzzle boxes have secret compartments. I think Puzzle boxes a awesome and I prefer High number moves boxes with innovative tricks. That's why I'm making a guide about making them,  click here to see my guide. But Now I wanna know what you think about, so please tell me everything

KenKen - Another great Japanese puzzle

KenKen is a new kind of logic puzzle from Japan by Tetsuya Miyamoto, who thought people were being failed by conventional methods of teaching. This is set to be the next sudoku The instructions are simple. These are for the puzzle in the second picture. All digits from 1 to 4 must be used in every row and column (no diagonals). The thick lined box has the target number for the values to reach in the thick box - one digit for a normal box. the symbol next to the value required is the only mathematical function you can use. Thick boxes that take up one normal box and have a a value - well, that value goes in that box. rules may differ slightly answers in picture 3

Planning a puzzle house

In another year or so we're hoping to buy an "investment opportunity" house and, as we're fixing it up, I would LOVE to add a house-wide puzzle leading to a final prize.  Ideally the mystery would start with seemingly decorative scrabble tiles in the guest bathroom and take the players all over the house and garden.  I'd love for it to have three or four tracks that all need to be solved to get to the final prize, that way we can do them in installments (get track 1 up and running, then 2, etc) so friends can start playing sooner rather than later.  I'd also love at least two of the tracks to use only stuff that'll go with the house when sold, like the cabinets, garden rocks, etc, so that the next owners can continue the game. I've started collecting ideas and would love to hear more.  The only limit is to please keep your ideas doable - while it would be fantastic to, say, have a wall slide away to reveal a secret underground cave I'm not so certain we can dig one of those out in our spare time.   Inspiration for all this comes mainly from the Myst games (ah, Riven, how I loved thee!) and this puzzle apartment in New York.

One of my Christmas gifts

My step-son made this awesome puzzle for me.  He knows how much I like Instructables so this was one of the gifts he made for me. Everyone knows that a hand-made gift is best.  And one hand-made by a loved-one even better.  But one that also includes the Instructables robot?  He gets points for paying attention to my hobbies!

[REQ] A physical switch for a remote LED bulb with removable parts to break the circuit

I realise that this might seem like it doesn't have a lot of practical applications but I am trying to replicate a typical puzzle from video games, the 'Fuse Box Puzzle' whereby the lights are off and the hero must solve a puzzle replacing the fuses to illuminate the room. I have an LE A60 B22 LED bulb which is controlled by a remote control and I would like to create something similar to the attached image whereby the three fuses must be inserted and the switch thrown to light the room. I would rather not install an actual fuse box for this however and would like this to control only the LED bulb. Does anyone have any idea where I should start with this?

Puzzling Travels of a Tom-Cat.

  Here's a puzzle I came across recently.  I've changed the context to stop people googling the answer :- A big ginger tom-cat leaves his home at 8:00 one morning and goes trundling around the neighbourhood, pausing here and there to 'leave his calling-card', stopping for a brief nap or two in a particularly warm spot, walking along fences, running through unfriendly gardens (woof woof) and  finding a warm car bonnet in a garage at 6:00 in the evening for a rest.  Unfortunately, the owner shuts the garage door and the cat is trapped for the night. At 8:00 the next morning the garage door opens and the cat comes scooting out.  Over the course of the day he takes the exact same path he took the day before but in reverse.  He stops in different places, makes his mark in other places and takes his naps at different places along the way, arriving back at his own house at 6:00 in the evening for a well deserved meal. The question :- What is the likelihood that there will be a time and place along the route where he is at EXACTLY the same point on the route at EXACTLY the same time of day on both days?

Help! Need to make an **easy** picture frame...

Hey y'all! So I need a bit of help here. I just finished this puzzle and I want to frame it (something I've never done before). I've looked around here and there aren't any frames that would fit a 20.5 inch X 28.5 inch puzzle. I refuse to pay the outrageous costs of custom framing, so unless something magically pops up, I will be building a frame for it. Building frames, building anything for that matter, is not my fortay and I would appreciate any and all tips y'all can provide. Thanks!!

E-mail alerts - a question for Robot.

Dear Robot,When I log onto the internet, it is my habit to first check my emails, including working down the list of comments in my daily alert from Instructables.I know you put the emails together, but what is your logic?The reason I ask is because the messages are not in chronological order, nor are they in reverse chronological order. They are in some sort of random order. For instance, there were three comments from one thread. They were made one after the other, each a reply to the one before, within a couple of minutes.Yet they arrived in my alert 2nd message, then third, then first, with other messages from other threads, posted hours apart, interspersed between them.It's not a life-threatening situation, but it is one of life's little puzzles.

A Puzzle featuring Xbox 360, a powerbook g4, and Connect360

Hi Everyone,I use a 12" powerbook g4 as a wireless adaptor for my xbox 360 (as shown here: https://www.instructables.com/id/Use-your-laptop-as-an-XboxXbox-360-wireless-adap/). I would like to use Connect360 (nullriver.com/products/connect360) to stream music and movies from my current computer onto the xbox 360. However, connect360 cannot see my xbox 360, and I suspect that is because it looks like a powerbook on the network, not an xbox 360, because it is using the powerbook's network connection. Is there anything i can do about this? This seemed like enough of a tweaking/hacking how-to that someone here might like to try it, or at least have ideas of how to go about it.Any thoughts would be greatly appreciated. Thanks in advance.

Disappearing Go g e?

You may have seen that Google has a crop-circle theme today, with a hovering UFO. The "l" is missing (even from the name of the image-file). A while ago, an "o" was kidnapped by a very similar UFO. Do the artists at Google know something we don't...? What letter is next?

Octopus in a box

On March 5th at the New England Aquarium octopus exhibit, a 7-foot long giant Pacific octopus climbed inside of a 15 inch-inch-wide box. The box was part of a set of acrylic puzzles that the aquarium uses to challenge the octopi during feeding time to keep them stimulated. Normally, the octopus opens the boxes sequentially to solve the puzzle and get its dinner. Last week however, the octopus found a crack in the largest box and rather than opening it, decided that it would crawl right inside.Aquarist Bill Murphy elaborates...What are the boxes made out of?The boxes are made of acrylic and were created by one of our long time volunteers in the fishes department.How many boxes are there?There are 3 different size boxes with different locks that are puzzles for the octopus to open.How do they work?I place one or two live crabs inside the box and the octopus has to learn how to open the box to get the food. I start the octopus off with the small box and once he has mastered the lock I switch to another box and once he has mastered each individual box I put a box inside a box to keep him active and challenged.What happened today?The largest box was actually broken by another octopus here at the aquarium three years ago so today the octopus decided to go through that broken opening instead of unlocking the large outside box to get to smaller box inside with the live crabs. This is the first time it has been witnessed here at the aquarium because they don't always open the box immediately and will wait till the night when they are more active to hunt for food. It's been a very fun occasion for visitors and staff!If octopi could live longer on land, we'd be their slaves for sure.Via New England Aquarium

No active partition error

Now I can't even boot off the cd, it just fails at the cd boot and gives me a "Not found any [active partition] in HDD" then says " Disk boot failure, insert system disk and press enter" I found this rather puzzleing as I just formated the disk on another computer and it's fine.

Digital Shower

I am planning and researching ideas on creating a DIY digital shower system.  The idea is to have an android device (Tablet, or old galaxy SII phone for now) installed along with an ardruino or some hardware interface to control the plumbing.  I would also like to use the android device for music weather etc. in the shower, but all that is built in. The only puzzle with the android device is getting it to interface with the hardware, and waterproofing it while still keeping the touchscreen functionality.  Any help would be greatly appreciated.

The Swallowtail Challenge.

Apparently, swallowtail butterflies have posed a bit of a puzzle to the sort of chap that studies that sort of thing. Butterflies actually have two pairs of wings - fore and aft, if you like.  Most butterflies have these pairs separated, to allow greater control over their flight, but swallowtail wings overlap, effectively becoming a single wing. They are stuck with a simple up-and-down flap.  The puzzle was; where does the control come from. It is hard to measure the forces acting on and in a live butterfly, so the researchers built a model - a small version of the hobbyists rubber-powered ornithopter, the same size and weight of a real swallowtail. They cast replica wings from fluorocarbons and polyurethane, and set it off in front of slow-motion video cameras. The conclusion? The unique shape of the wing provides automatic control - the combination of flexibility of the wing and the rigidity of the veins provide a passive control and stability. The point? Why am I posting this here?  As a challenge: the swallowtail ornithopter was (except for the wings), very basic - wire frame and a rubber band. How small could such an aircraft go? How tiny could you, dear reader, build a working ornithopter? Institute of Physics article. (Free registration required to read it in full, if you are quick)

What does the universe look like?

I watch these magnificent programs about the universe, so wonderfully explained by Morgan Freeman.  I am puzzled with one question.  How can the science predict the size of our galaxy in somewhat vivid details?  So, here is my analogy.  With the space technology at hand, taking a picture of our own galaxy is the same as taking a picture of the Empire State building from one of its balconies.  Can someone please elaborate on this subject. Thank you.
