Motorized Couch Mobilizes Sofa Potatoes


Folks know IKEA for 2 issues: Swedish meatballs and low cost furnishings. You possibly can depend on that furnishings falling aside the primary time you progress, but it surely positive is inexpensive. Bitluni’s native hackerspace had an outdated IKEA sofa going unused, so he and his associates got down to motorize the couch to create a rideable sofa.

The motors for this mission got here from an outdated Hoverboard, which is a unbelievable supply of components for makers. Hoverboards have been highly regarded for some time there and now thrift shops and storage gross sales are filled with the issues. Used Hoverboards — particularly those who aren’t working anymore — are very low cost and include some fairly nifty {hardware}. That {hardware} features a pair of wheels with highly effective hub motors, motors drivers, and a beefy battery pack. On this case the battery pack was kaput, however the motors and driver board have been working.

Bitluni’s thought was to connect the Hoverboard motors to the IKEA sofa together with a pair of casters in order that it wouldn’t must steadiness itself. The development was easy as a result of the couch’s wooden body supplied loads of area to mount the motors and casters. To compensate for the load, the staff added an axle-like tube between the 2 motors. That helped to cut back the bowing, although it didn’t remove that downside fully.

The most important problem was interfacing with the Hoverboard’s controller in order that they may take handbook management of the motors. A bunch of various producers produced Hoverboard fashions and so they’re all a bit totally different. And, in fact, these producers by no means printed knowledge on their {hardware} design or communications protocols. Thankfully, the staff was capable of finding customized firmware created by Lucy Fauth that works with this explicit Hoverboard controller. That lets the person management the motors with a Wii Nunchuk distant.

As a result of the Hoverboard’s authentic battery was lifeless, the group ended up utilizing a battery pack from an electrical bicycle. That supplied loads of present and capability — greater than the unique battery pack.

With all of these items in place, that they had a motorized couch that they may trip in consolation. It was surprisingly agile, which proves how highly effective these Hoverboard motors actually are.
