These days, live music performance often involves electronic synthesizers and computers rather than traditional instruments played by hand. To aid in his own performances, [alekappa] built a special interface to take signals from a joystick and convert them to MIDI messages carried over USB.
The build is simple and straightforward, using a Teensy LC to interface with a simple gameport joystick. With a smattering of simple components, it’s easy to read the outputs of the joystick with only a little debounce code needed to ensure the joystick’s buttons are read accurately. Similarly, analog axes are read using the analog-to-digital converters onboard the microcontroller.
This data is then converted into control changes, note triggers and velocity levels and sent out over the Teensy LC’s USB interface. A mode switch enables changes to the system’s behaviour to be quickly made. The device is wrapped up in a convenient housing nabbed from an old Gameport-to-USB converter from many years ago.
It’s a neat project and we’re sure the joystick allows [alekappa] to add a new dimension to his performances on stage. We’ve seen other great MIDI controllers, too, from the knitted keyboard to the impressive Harmonicade. If you’ve got your own mad musical build under construction, don’t hesitate to drop us a line!
One of the biggest reasons for playing older video games on original hardware is that emulators and modern controllers can’t replicate the exact feel of how those games would have been originally experienced. This is true of old PC games as well, so if you want to use your original Sidewinder steering wheel or antique Logitech joystick, you’ll need something like [Necroware]’s GamePort adapter to get them to communicate with modern hardware.
In a time before USB was the standard, the way to connect controllers to PCs was through the GamePort, typically found on the sound card. This has long since disappeared from modern controllers, so the USB interface [Necroware] built relies on an Arduino to do the translating. Specifically, the adapter is designed as a generic adapter for several different analog joysticks, and a series of DIP switches on the adapter select the appropriate mode. Check it out in the video after the break. The adapter is also capable of automatically calibrating the joysticks, which is necessary as the passive components in the controllers often don’t behave the same way now as they did when they were new.
Plenty of us have joysticks and steering wheels from this era stored away somewhere, so if you want to experience Flight Simulator 5.0 like it would have been experienced in 1993, all it takes is an Arduino. And, if you want to run these programs on bare metal rather than in an emulator, it is actually possible to build a new Intel 486 gaming PC, which operates almost exactly like a PC from the 90s would have.

Seeing this IBM joystick again really brings back memories. But it can be used on a modern system thanks to this USB conversion project.
This particular model had a connector which is foreign to us. It looks like a boxy USB-A plug, but has an eight-pin sockets which looks like it’s 0.1″ pitch. You could try to make your own male connector using a dual-row pin header, but [Gruso] just went ahead and lopped off the end of the cable. He managed to dig up the pin-out for the device and found that it could be wired up to a gameport — the connector being the only real difference. He gutted a USB gameport adapter, removing the DB15 connector and soldering directly to the board. The boxy old peripheral has just enough room to house that PCB.
