Concrete Table Even Includes A USB Hub

When designing furniture, material choice has a huge effect on the character and style of the finished product. Wood is a classic option, while more modern designs may use metal, plastic or even cardboard. Less popular, but no less worthy, is concrete. It’s heavy, cheap, and you can easily cast it into a wide variety of forms. [KagedCreations] thought this would be ideal, and whipped up this nifty piece of furniture with an integrated USB hub.

A pair of melamine shelves were scrapped to build the form, in which the concrete table is cast. Melamine is a popular choice, as it’s cheap, readily available, and releases easily from the finished concrete. Along with the USB hub, a wooden board is cast into the base of the concrete table top. This serves as an easy attachment point for the pre-made hairpin-style legs, which can be installed with wood screws.

The final result is a tidy side table that has plenty of heft to keep it stable and secure. It’s not the first concrete USB hub we’ve seen, but it’s likely the heaviest thus far. We’d love to see a version with an integrated charging pad, too – if you build one, be sure to let us know. Video after the break.

3D Printed Desk Harnesses The Power Of Fusion 360 And McMaster-Carr

Black pipe furniture is all the rage now, and for good reason — it has a nice industrial aesthetic, it’s sturdy, and the threaded fittings make it a snap to put together. But if you’ve priced out the fittings lately, you know that it’s far from cheap, so being able to 3D-print your own black pipe fittings can make desks and tables a lot more affordable.

Cheapness comes at a price, of course, and [Vladimir Mariano] takes pains to point out that his desk is a light-duty piece that would likely not stand up to heavy use. But since the flange fittings used to connect the plywood top to the legs and as feet would cost about $64 all by themselves from the local home center, printing them made sense. Together with custom pieces to mount stretchers between the legs, the 3D-printed parts made for a decently sturdy base.

But the end product isn’t the main point of the video below. Thanks to the ability to browse the McMaster-Carr catalog from within Fusion 360, [Mariano] was able to seamlessly import the CAD model of a suitable iron flange and quickly modify it to his needs. The power of this feature is hard to overstate; you can literally browse through a catalog of engineered parts and print usable replicas instantly. Sure, it’s not made of metal, but it’s a huge boon to designers to be able to see how the final product would look, especially in the prototyping phase of a project.

Not familiar with McMaster-Carr? It’s an engineer’s online playground, and we covered the ins and outs of doing business with McMaster a while back.

Interactive LED Table

Some hackers make functional things that you can’t allow to be seen in polite company. Others make beautiful things that could come from a high-end store. [Marija] falls into the second category and her interactive LED coffee table would probably fetch quite a bit on the retail market. You can see a video of the awesome-looking table, below.

It isn’t just the glass, MDF, and pine construction. There’s also a Bluetooth interface to a custom Android application from [Dejan], who collaborated on the project. However, if you aren’t comfortable with the woodworking, [Marija’s] instructions are very detailed with great pictures so this might be a good starter project.

Rubik’s Cube Table Has A Hidden Surprise

[Nothorwitzer] built a pretty incredible Rubik’s Cube table with hidden storage. The coolest feature of this table is the way it opens. Twisting the top section of the cube causes two drawers to pop out from the sides. The further you turn the top, the more the drawers extend. As the top hits its rotational limit, the lid of the cube lifts up, revealing the entire top section is hollow.

[Nothorwitzer] built the table from plywood, hardboard, and MDF. Hiding inside the base is an old car wheel hub and bearing. The entire rotating system spins on this assembly. The drawers are actuated by an ingenious set of plywood cams which push the two opposing drawers out as the top assembly rotates. Two levers pop the top open.

The attention to detail here is amazing. [Nothorwitzer] build a set of hidden hinges that make the lid invisible, yet allows it to lift up and over the edge of the cube. A spring ensures that the heavy lid will pop open neatly. The lid fit is so close that air pressure ensures the top doesn’t slam down when it is dropped.

While the internal parts of the table are left in bare wood, that the external parts had to match a real Rubik’s Cube. [Nothorwitzer] scrambled a cube, then copied the colors. The panels are made of cut hardboard. Each panel is spray painted, then hot glued to the cube. The body is plywood which [Nothorwitzer] grooved with a router to match the profile of a real Rubick’s Cube.

The project doesn’t end here. [Nothorwitzer] has created a second cube, which is even more tricky. The lid pops by pressing in one section. The drawers operate in a similar way, but there is a lever to engage or disengage the drawer opening. This may be the perfect place to hide your retro gaming systems!

A Massive Adjustable Standing Desk From Scratch

Standing at your desk all day is healthier by far than sitting, but the commercial options tend to be expensive. [drivenbyentropy] had to contend with a heater right where the desk would go, but building an adjustable office desk to accommodate it turned out — well — gorgeous.

Two 18″ heavy duty 12 V DC actuators raise and lower the desk with a 600 lbs static load capacity and 200 lbs of  lifting load each. One actuator is actually slightly faster than the other, so instead of working out something fancy, [drivenbyentropy] simply extended the cable length on the faster actuator to disguise the difference.

Framed with some standard 2×4’s and sheathed with plywood, the massive four by eight foot desk has twelve ball-bearing drawer slides in the legs to add stability and smooth out height adjustments. Because of its size and having to build around the heating unit, the desk is stuck in the room since it does not easily come apart. There is, however, easy access to the two electronics compartments for troubleshooting!

Scissor Lift Table From The Wood Shop, For The Wood Shop

The value of a mobile adjustable height cart in the shop can’t be overestimated. From moving tools around to installing heavy fixtures on walls and ceiling, a scissor-lift platform is a great tool. Commercial versions get a bit expensive, though, so a shop-built scissor lift table made of wood might be a nice project for the budget-minded to tackle.

Wood might not be your first choice for a fixture such as this, but it’s what [Marius Hornberger] is set up to use, and with proper species selection and careful engineering, it can make for an amazingly sturdy table. [Marius] chose ash for his parts, a wood with a long history of performing well under difficult conditions. The table is not all wood, of course; metal bushings and pins are used in the scissor mechanism, and the lift drive is a stout Acme-thread screw and nut. We’re impressed by [Marius]’ joinery skill, and with how sturdy the table proved to be.

Not a lot of woodworking projects seem to show up in our tip line for some reason, which is a shame. We love to feature wood builds, and like our own [John Baichtal] recently pointed out, the health of the wood shop is often a leading indicator of the health of a hackerspace.

A Table From Beyond Infinity

Infinity mirrors are some far-out table mods and make a great centerpiece. Instructables user [bongoboy23] took a couple steps beyond infinity when designing this incredible table tailor-made for our modern age.

Poplar and pine wood make up the framing, and red oak — stained and engraved — make for a chic exterior. Programmed with Arduino and run on a Teensy 3.1, the tabletop has 960 LEDs in forty sections. There are, four USB ports hidden behind sliding panels, as well as a two-port AC outlet and an inductive charging pad and circuit.  A hidden Adafruit TFT touchscreen display allows the user to control the table’s functions. Control is limited to changing lighting functions, but Pac-Man, Snake, and text features are still to come!

Weighing in at $850, it’s not a cheap build, but it looks amazing.
