Beds! They don’t move around enough, so the young people say. They need more motors, more horsepower, more self-driving smarts – right? Honestly, we’re not sure, but if that’s the question being asked, [randofo] has the answer.
Aptly named, Bedfellow is an art project that sought to create a bed that could explore and socialise with occupants aboard. The core principle was not just to create a bed that could move under its own power, but one that could intelligently drive around and avoid obstacles, too. This is achieved through the use of ultrasonic sensors, with an Arduino Mega as the brains. The bed chooses a random direction in which to move, checking for obstacles on the way. It’s pretty basic as far as “self-driving” technology goes, but it gets the job done.
Far from being a lightweight artistic statement, the bed has some serious performance credentials. The drivetrain is a couple of 4 horsepower DC motors with speed controllers cribbed from a golf cart. These are fed through a 20:1 gear reduction to boost torque and avoid the bed moving too quickly. [Randofo] reports it can comfortably haul 12 people without slowing down, and we don’t doubt it. With that much power, your average flatback bed would be ripped to pieces, but never fear for this one – there’s plenty of heavy engineering holding it together.
It’s refreshing to see an art project executed with both elegant aesthetics and brutally powerful hardware. Sure, it might not be much good for sleeping unless you live in a loft with a concrete floor, but hey – they’re awfully popular these days. Now all it needs are some ground effects.
Talk about an awesome project. [Lucas Evanochko] was commissioned to build this totally rad Delorean style golf Cart for Red Deer College’s 30th annual Golf Tournament.
According to him, it’s been about 600 hours in the making – and they only started building it in July. This past week was its big unveiling, and it has had an overwhelmingly positive response so far!
They started with one of the club’s golf carts and modified it heavily, relying on the automotive expertise of [David Keykants] and [John Perrin] to turn it into the aw-worthy time machine it is today. It has a 7” tablet built right into the dash to play music and use the Fluxy88 Time Circuits app. A big array of arcade buttons hooked up to an Adafruit Audio FX board play various sound bites from the movie, including the theme music!
All the accessories are powered off of a separate 12V system from the main 48V drive line. Oh and the Flux Capacitor? It’s controlled by a Trinket Pro. Check it out after the break. We love the detail that went into this!

Want to put 100 horses into your golf cart and then take it to the Dragstrip? Why not? [Mac McAlpine] did just that by dropping a 2007 GSXR 600 EFI into a 1987 gas-powered Yamaha golf cart. After the break you can see a video of the test run, as well as an overview of the modifications made when swapping engines. [Mac] mentions that the setup still uses the stock bike chain and jackshift even with the upgrade in power. He has, however, upgraded both the front and rear axles with caliper and drum brakes respectively. There’s also a NASCAR Car of Tomorrow wing on the roof to help keep the wheels on the pavement.
Good thing he’s wearing that helmet. Without a seatbelt it’ll make smashing through the windshield a little more comfortable. Drive carefully [Mac]!

After making a few units for the new Discovery t.v. show called Weaponizers, [Jeremy] decided to release this video showing how to modify a golf cart for radio control. The radio and controller are basic off the shelf R/C gear, running some linear actuators.
