Custom Storage Boxes, From Cardboard And 3D Printed Bits

It’s not that storage boxes and organizers are hard to find. No, the problem this project set out to solve was more nuanced than that. The real trouble [theguymasamato] had was that his storage options — wide shelves and deep drawers — weren’t well suited to storing a lot of small and light objects. The result was a lot of wasted space and poor organization. To make matters worse, his big drawers had oddball dimensions, meaning that store bought organizers weren’t a good fit either.

To solve these problems, [theguymasamato] decided to design his own stackable boxes to store small and light objects far more efficiently than before. The design also allows the boxes to be made in a variety of sizes without changing any of the 3D printed parts. Carefully measured and cut cardboard is critical, but that’s nothing a utility knife and ruler can’t solve. The only other requirements are a few simple plastic parts, and some glue. He can fit six of these inside a single one of his drawers with enough room to access and handle them, but without wasting space.

Cardboard is really versatile stuff. Not only has it been behind some amazingly complex devices such as this tiny working plotter, but we’ve seen it form major components in the remarkably ambitious cardboard CNC.

An Enigma Wrapped In A Riddle Wrapped In A Vintage Radio

Puzzle boxes are great opportunities for hacking. You can start with a box which was originally used for something else. You get to design circuitry and controls which offer a complex puzzle for the players. And you can come up with a spectacular reward for those who solve it. [thomas.meston’s] Dr. Hallard’s Dream Transmission Box, which he created for an original party game, has all those elements.

The box was a broken 1948 National NC-33 Ham Radio purchased on eBay after a number of failed bids. Most of it was removed except for the speaker. The electronics is Arduino based, so most of the smarts are in the form of code. Potentiometers and a switch provide the mechanism for players to enter codes. And when the correct code is entered, a relay triggers an external smoke machine and turns on a laser which illuminates a party ball, rewarding the victors. And of course, there are also sound effects as well as a recorded message.

We weren’t kidding when we said puzzle boxes make great hacks. Here’s one which ignites fireworks, one made only from discrete components, and a valentine based one which makes your significant other work for their gift.

Box Forts For Adults: Best Practices And Design Strategies

Many a grown up can reminisce about building various architectural wonders in their youth. Forts, whether based on boxes or blankets, were the order of the day, and an excellent way to spend a rainy Sunday afternoon.

It just so happens that there is no law against scaling up such activities once one has reached the age of majority. However, to build a structure at this level takes some careful planning and consideration, and that is the purpose of our article here today.

Location, Location, Location

To avoid an awkward conflict, be sure to warn your housemates of impending construction well ahead of time.

The first major consideration when starting your build should be the area in which you wish to do it. Building inside has the advantage of avoiding the weather, however hard floors can lead to sore knees when crawling around. Additionally, you’re a grown up now, so it’s less likely your peers will be impressed to hear you sat inside a box in your living room.

No, if you’re going to do this right, you’ll want to go outside. A nice flat lawn is best, providing soft ground and plenty of space. The challenges of the elements will guide your work – sitting inside your cardboard home feels all the more satisfying when you’re cosy and dry as you listen to the patter of rain on the roof. There’s a real sense of accomplishment when you’ve built something that can survive the harsh outdoors, and besides, the views are better, too.

Have A Laser Cutter? Here’s A Cool Combination Lock Box You Can Build!

Laser-cut plywood boxes are cool. Don’t believe me? Take a look at the free projects out there for people to get started with when they get a laser cutter – it’s obviously a popular genre of project. Laser cut plywood boxes with combination locks are even cooler, especially when the combination is entered on four separate number selectors, on four sides of the very same box.

That’s exactly what [Sande24] has done, and the final result is mesmerizing. 30-40 parts are cut from plywood with a laser cutter, and assembled to construct the lockbox. The design could easily be reused to make the box out of acrylic, or even aluminum or steel if you were so inclined. Check it out in the video below.

Add Slots And Tabs To Your Boxes In FreeCAD

FreeCAD is a fairly sophisticated, open-source, parametric 3D modeler. The open-source part means that you can bend it to your will. [Alexandre] is working on a module that lets him easily add tabs, finger joints, and t-slots to models (YouTube link, embedded down under).

Right now the plugin is still experimental, but it looks usable. In the video demo, [Alexandre] builds up a simple box, and then adds all manner of physical connective pieces to it. You’ll note that the tabs look like they’re pieces added on to the main face — that’s because they are! He then exports the outlines to SVG and erases the lines that separate the tabs from the sides, and hands these files off to his laser cutter. Voilà! A perfect tab-and-t-slot box, with only a little bit of hand-work. ([Alexandre] mentions that it’s all still very experimental and that you should check out your design before sending it to the laser.)

Make Your Mailman Nervous With A Wifi Enabled Mailbox

“It’s not a bomb,” the mailman whispered to himself as he reached for [atxguitarist]’s mailbox, giving a nervous glance at the small black box stuck to the side. “This is THAT house, it’s not a bomb. I’m sure it’s not a bomb,” he muttered as a cold bead of sweat ran down his neck. His hand approached slowly, shakily. The mailman gathered courage, then, in a single quick movement, opened the box. He sighed relief as nothing happened. Somewhere in [atxguitarist]’s house a recording wailed “You’ve got mail!”

The mailbox enhancement in question is a hacked Amazon Dash Button in a project box. When the door of the mailbox is opened, a magnetic reed switch simulates a button press on the Dash. The Dash transmodulates the signal into WiFi pixies which are received by a Raspberry Pi. The Pi’s sole purpose in life is to run a 24-line Python script that plays the famous sound from AOL’s mail software and sends a notification to his phone.

Aside from unnerving the mailman, it’s a cool hack and keeps you from slugging it out there in the cold or rain to witness an empty box.

Puzzle Box Is Rigged To Blow

[Sande24] needed a gift for his father’s birthday. He decided that rather than simply give his father the gifts, he would present his father with a unique challenge. The gifts are locked inside of a multi-stage puzzle box. This isn’t your average puzzle box though. This one is rigged to blow.

The puzzle box was designed to test his father’s reflexes, mind, and luck. The finished product looks sort of like a wooden crate made from particle board. The box contains three levels, each with its own gift and its own task to be completed.

With the lid opened, the first compartment and puzzle is revealed. Inside of the compartment were a new pair of gloves, meant to protect the father’s hands when working on the puzzles. The first puzzle is built into a sheet of wood with several custom-made levers. The levers must be moved into position in order to remove the wooden sheet and reveal the next level.

The first lever triggers a home-made detonator that eventually lights a series of fireworks placed around the box. You need to solve the puzzle box fast enough to prevent the fireworks from destroying the gifts that lay inside. [Sande24] was unable to legally purchase fuses where he lived, so he had to make his own.

The second level held a gas mask, also meant to protect the father from the booby traps of this mysterious box. This level, also made from a sheet of wood, has nine squares drawn on it. Each square is labeled with a different number which goes into solving a mathematical function (x^5-25x^4+233x^3-995x^2+1866x-1080 = 0). The solution to the function would reveal the safe path to be used to cut the wooden platform in half. Unfortunately [Sande24’s] father cut the wrong squares and released a huge amount of vinegar into the box. Oops.

The bottom level contained the final puzzle and the locked treasure compartment locked with an ordinary padlock. To find the key, another puzzle had to be solved based on a series of wooden levers labeled with different shapes. The shapes provided clues to the order in which the levers should be pulled. Once the levers were moved into position, two compartments were unlocked. One of them contained the key to the treasure box. The other contained another booby trap which would set off more fireworks, destroying the final gift of four cans of Kuld beer. That’s a lot of work to get a a few cans of frothy beverage!
