Puzzle Box - Pins

Name :	Pins Box
Number of moves :	7
Instructions :	Register for interest

This puzzle box was constructed when I was outstation, so the colours and mechanisms were slightly flawed. However, this was still a difficult box due to its unorthodox final move.

(The video is split into 2 sections due to length)

Many people weren’t able to solve this box because they didn’t think of flipping it over. This design is quite an old one, but I’ll be happy to create a new improved design with build instructions that you can buy (at a small price, of course!)

Thank you for reading my blog.

The Mini Cube

Name :	The Mini Cube
Number of moves :	3

This mini cube was originally intended to go with the main cube; sort of an introduction or “appetiser” to the main cube. I am considering to share how to build this Mini Cube for free, drop me a message if you are interested.

Here’s a video of the box solve. 

Well there you have it! A classic top-open mechanism with 2 sliders.

Thanks for reading my blog! 

The Cube - Explanation

The structure of the box is as follows : 

Individual lock systems -> red and blue locks -> yellow drawer with tool -> slider reveal

Individual lock systems : 

Each lock system will move the ring out of place and drop a pillar down which unlocks the red and blue locks (shown later) 

2nd lock system : 

Red and blue locks : 

The lower locking system drops pillars through the system that were blocking the red and blue sliders. 

This is how the pillar locks work : 

After the red / blue locks have been slid out, they can be pushed to unlock the yellow drawer (series of pictures)

After the blue lock has been slide to the side, the fox piece can now move with the yellow drawer and slide out along with it. 

Yellow drawer and tool : 

This part doesn’t need much explanation; most of it has been covered in the other sections. The tool is a simple gear that can be inserted into the hole. 

Reveal : 

The last thing in my explanation would be the reveal. It’s actually a huge gear rack that protrudes all the way through every single layer (I don’t have the special, smaller gear rack) 

The rack is pulled up by a gear within the box (later  (video for further explanation)

This box was really a joy to design and let people try. Hope I can continue making these boxes and improve them as I go along.

The Cube

This marks a new high for the development of puzzle boxes! Introducing… The Cube!

Now I just want to make a tiny announcement. I’ll be selling my puzzle box instructions! Next time, instead of showing you how it works, I’ll just give a little teaser for the solving process so that you get interested. 

I’ll still be giving the full solving process this time though because I’m not planning to produce instructions for The Cube. It’s just slightly unreliable and too difficult to reset. If you’re really interested then feel free to drop me a line though.

Now… let’s start with a video of the solve (split into 2 parts because the video is too long)

Note : Video was edited to make it shorter

The full explanation of the mechanism will be shown in another post, stay tuned!

Puzzle Box - Elegant

Name :	Elegant Box
Number of moves :	5
Instructions :	Register interest

Recently, I’ve actually gotten into building puzzle boxes using Lego. Basically, a puzzle box is a box that can only be opened after solving a puzzle, or making a series of discoveries (Wikipedia). I discovered them on YouTube and started making my own.  

The very first prototype was this huge chunky box. I didn’t manage to get many photos of it before it was dismantled, but here’s one. 

I might cover the solving process in another post, because today’s post is about Version 2. 

I nicknamed this version “Elegant” because I managed to make it much more compact and refined compared to the first prototype. 

Here is a video of the solving process. 

The lock and drawer need no explanation, but here’s a video to show how the key is revealed when you turn the knob. 

Once inserted, the knob will turn a lever which will push the key upwards and reveal it. 

Next is the locking mechanism for the drawer which required quite some thought. I’m really happy with this one and I hope I can include a similar, upgraded version in future boxes.

Basically, the wedged key moves a latch out of place so that you can open the spring-loaded drawer. This design isn’t foolproof - I’ve had people open the drawer just by jiggling it - but foolproof boxes are in the making, stay tuned!

Seaside Mansion & House on Stilts

Today’s task : Build a house. Not content with a simple and standard house, I decided to build a mansion and that slowly became a Seaside mansion. 

The design is quite simple, utilizing SNOT bricks and clips to mount objects in interesting designs. The tree in the corner is made by simply not fully connecting the individual 1x1 green pieces. One side is tilted more than the other so the curved effect is achieved. 

This section is the garage for the house. Quite standard in any case, using corrugated grey bricks to make a shutter door effect. Tall bushes are achieved using the same 1x1 green parts as the tree. Another feature is the window. Using unconventional methods like not fully mounting bricks and adding curves to the model, I achieved a small and minimalistic but satisfying window. 

The side is made using SNOT bricks to achieve a tan brick effect. Also, the tree on the side has a 1x1 round plate brown piece to represent coconuts. 

A closeup look of the house. Starting from the bottom up, bushes and greenery is essential, while a side-mounted glass door using SNOT bricks add a nice effect. Windows and other details make it seem like a home. On the second floor, and arch and curved pieces are used for depth, whereas another glass door adds repetition. 

The back of the house. I decided to make the back under construction as I wasn’t quite sure what to do with the back. Also to note is the small white grill window standing out among the black cladding. 

Also a quick mention of my daddy’s invention: House on Stilts. It looks slightly like a convention center…

Automation : History Project

Some time ago, my history teacher gave us an assignment to make a modern castle. It needed to have the elements of a medieval castle and modern amenities at the same time. 

Since I am considerably experienced in the area of Arduino hardware and software, I decided to attempt a working drawbridge and portcullis. After all, what could be more impressive than a remote-controlled gate and door for a castle?

The first step was to set up the IR hardware. I had an existing Arduino remote control and also an IR receiver that could be applied nicely for this purpose.

The IR receiver had to be wired rather inconveniently using standard stripped wires to a breadboard.

Next was the portcullis. I utilized a pulley, a string with hook and a servo motor to achieve linear motion (up and down). I needed to find a perfect gear to connect to the servo so that I could pull the portcullis up and down as much as I wanted.

In the end, the breadboard was positively covered with wires. I used wire ties to secure and organize the wires a bit so that it was more pleasing to the eye. The Arduino was screwed down nice and tight for travel.

The IR receiver, secured using cardboard and wired using crocodile clips on two sides and a normal stripped wire in the middle. I had to secure this one with wired ties also to avoid confusion and short-circuits. There was one time that the entire Arduino heated up and I hastily removed the USB!

The drawbridge utilizes a simple cardboard piece mounted to the servo arm. Simplicity in this form allowed me to fix the numerous bugs that arose with more ease. And of course, the best part is that it still fulfilled its objective!

The entire set up could be powered by a standard 3-pin plug once the code was uploaded. To do that a computer was needed but I could do it before I headed off to school. Other methods included using a battery but I didn’t use that because of the high energy consumption of servo motors. 

I’m happy to say that the presentation went nicely but the Arduino ran less smoothly than expected…. maybe that’s an improvement for next time? Stay tuned!

Bomber

For ages I have struggled to figure out an effective way of dropping missiles. Loose mounts dropped them inconsistently, hard mounts were hard to deploy, but one day, I finally came up with an idea (with inspiration from my daddy)

So the bomber was born. A relatively normal design not very different from any other aircraft I’ve designed, this plane was differentiated by its unique weaponry.

As for its normal traits, this plane has 4 machine guns in its wings and a curved, bulbous nose. An orange windscreen shields a robot who is the main pilot. Covering could not be designed for the pilot so the bomber relies on fighter guards and agility to survive. 

A view of the underside of the plane. Two extra machine guns are mounted at the back for dogfights and the weapon delivery system is between them. 

It can be detached for maintenance and reloading. From here, the mini-missiles can be seen- a special design just for this model.  

The system is quite self-explanatory but to further clarify, after one missile has been released, the next one is pushed back up by the circular section of the drum and subsequently drops within, starting the next cycle. 

For reloading, a special slot is included there. Maximum capacity is 4 missiles. Fins help to promote stability and also look cool at the same time.
