Hoverboard Powered Sofa Is Fun And A Bit Dangerous

Discarded hoverboards are a great source of free high torque motors for hacking. This can include crazy but fun projects like this hoverboard-driven IKEA sofa, as demonstrated by [Bitluni] and his friends at xHain Hackerspace in Berlin.

With a couple of dead hoverboards in various conditions and a working e-bike battery, the group started exploring different options to put together a usable drivetrain. The first attempt involved commanding the motor drivers directly by intercepting communication from the gyro-based controller. The 9-bit communication protocol was a tough nut to crack, so they tried (and failed) to use the gyro-boards directly as the controllers. In the process of researching they discovered someone had created alternative firmware for the hoverboard controllers to allow control with a Wii Nunchuck. There is even a web-based config tool for compiling the firmware.

With some wood spacers screwed to the bottom of the sofa, the hoverboard motors could be attached by simply screwing their enclosure to the bottom of the couch and adding a section of PVC pipe between the halves for wiring. Caster wheels were added to the rear corners of the sofa to complete the chassis. The motors were very sensitive to control inputs on the Nunchuck, so riding the couch tended to rapidly turn into a rodeo event. The couch also wasn’t made to carry its load on the outer corners, so it had to be reinforced with plywood after it started cracking.

We’ve seen plenty of hacks that involve hoverboard motors, including an electric skateboard with mecanum wheels and a surprisingly practical e-bike conversion.

Voice Controlled Sofa Meets Your Every Beverage Need

It’s often taken for grated, but the modern world is full of luxuries. Home automation, grocery delivery, and even access to the Internet are great tools to have at hand, but are trivial to most of us. If these modern wonders are not enough for you, and the lap of luxury is still missing a certain je ne sais quoi, allow us to introduce you to the ultimate convenience: a voice controlled, beer-dispensing sofa with a built-in refrigeration system.

This is a project from [Garage Avenger] and went through a number of iterations before reaching this level of polish. Metal work on the first version didn’t fit together as expected, and there were many attempts at actual refrigeration before settling on repurposing an actual refrigerator. With those things out of the way, he was able to get to the meat of a project. The couch-refrigerator holds 12 beers, and they are on a conveyor belt which automatically places the next beer onto the automated drawer. When commanded (by voice, app, or remote) the sofa opens the drawer so the occupant can grab one easily without having to move more than an arm. Everything, including the voice recognition module, is controlled by an Arduino, as is tradition.

The attention to detail is excellent as well. The remote control contains a built-in bottle opener, for one, there are backlights and a glass cover for the refrigerator, and the drawer is retracted automatically when it senses the beer has been obtained. We couldn’t ask for much more from our own couches, except maybe that they take us where we want to go. But maybe it’s best to keep these two couch use cases separate for now.

Reupholstering A Couch, With No Prior Experience

Upholstery is a craft that dates back far longer than many we feature on Hackaday. It requires patience, attention to detail, and a series of specialised skills. If you fancy yourself to be like a young Jack White, you might have considered trying your hand at a piece or two. [darkpine] did just that, and the results are impressive.

The couch was sourced from an online bartering platform, and was in a sad and sorry state after years of use. According to the original owner, the couch was over 100 years old and had been passed down through several generations. Last reupholstered in the 1970s, it was in dire need of repair. Wooden trim was falling off, fabric was fading, and resident cats had been sure to leave their mark.

[darkpine] set about things the right way, stripping the couch back to its bare bones. Taking careful note of the original construction, diagrams were made to ensure the springs could be retied in the correct fashion. Fresh burlap was installed, followed by foam and a layer of cotton batting. Careful attention was then paid to the fabric covering, with hand stitching used along the arms to get an absolutely perfect pattern match along the seams. With the hard part done, the wood was then restored and waxed to a glorious shine.

The final results are astounding, especially when noting that this was [darkpine]’s first ever upholstery project. We don’t see a lot of this kind of thing around here, but it’s not completely unknown.
