Many arcade machines can be emulated and handily controlled with the standard joystick and button combos. However, a few don’t feel quite right without some extra equipment, motorcycle racing games being one of them. So, no longer content to go to an arcade to get his fix, [The Q] welded his own motorcycle simulation rig for playing racing games at home.
After an initial design was sketched out, rectangular tube steel was cut to size and welded together with a MIG welder. A central shaft linked to some secured bearings made the central pivot point. A few pistons offered the resistance needed for leaning into the curves. To the central shaft, a seat and an old bicycle fork were attached. A clever linkage from the handlebars to the base causes the bike to tilt when turning the handlebars and vice versa.
The bike was ready for prime time after some grinding, orange paint, a license plate, and some lights and grips. [The Q] just needed to get the angle of the bike into the simulation of their choice. While we expected a teensy or other microcontroller emulating a controller, [The Q] went for a somewhat simpler approach, and 3D printed a cradle to hold a PlayStation controller. Little levers pull strings to articulate the joystick, and a cable from the throttle grip pulls back the trigger on the controller. All in all, the experience looks pretty decent, particularly when you’re comparing it to a motocross arcade machine. What it really needs are some fans blowing for the effect of the air stream coming at you.
If you’re thinking about busting out the MIG to make a rig of your own, maybe consider making a homemade car racing rig to complement the bike.

If you desire a sim gaming rig, there are off-the-shelf options up and down the market that stretch as high as your budget can afford. Some choose to eschew this route, however and build their own from scratch. Few people go quite so far as [Popicasa POPStuDio], however.
The first version of the rig is about as hacked as you can possibly get, and it’s a joy to see it built from scrap. The wheel itself and the pedals are all built out of old PVC pipe, with a bunch of old wood screwed together for the frame. A cheap USB gamepad serves to handle input to the PC for the pedals and H-shifter. The H-shifter uses simple power switches, repurposed in an ingenious way to sense gear position. The knob itself is cast out of what appears to be hot glue. Steering is done by connecting the wheel to a flexible shaft that tips a smartphone back and forth, using its internal accelerometers and gyros to sense rotation. It’s not clear how this is tied into the PC running Project CARS, but it’s impressive nonetheless.
Version 2 of the build takes things up a notch, using an Arduino Leonardo to handle steering and pedal functions as a Human Interface Device. There’s also force feedback, via a hefty motor attached to the steering shaft via a belt drive. This version implements an H-shifter as well as paddle shifters too for a more modern experience.
Both builds are unique in the modern era for eschewing CNC or 3D printed parts. It’s all done by hand, taking days of effort, and using only basic tools. It’s refreshing to see such a complex build done with nothing but simple materials and sheer commitment. We’re sure [Popicasa POPStuDio] enjoys the rig, and we can’t wait to see where it goes next. Perhaps the next iteration will even feature a motion platform, perhaps built out of old forklift parts? Only time will tell. Video after the break.
