Cranking Up The Detail In A Flight Simulator From 1992

December 5, 2024 by Tom Nardi 21 Comments

Nostalgia is a funny thing. If you experienced the early days of video games in the 1980s and 90s, there’s a good chance you remember those games looking a whole lot better than they actually did. But in reality, the difference between 2023’s Tears of the Kingdom and the original Legend of Zelda is so vast that it can be hard to reconcile the fact that they’re both in the same medium. Of course, that doesn’t mean change the way playing those old games actually makes you feel. If only there was some way to wave a magic wand and improve the graphics of those old titles…

Well, if you consider Ghidra and a hex editor to be magic wands in our community, making that wish come true might be more realistic than you think. As [Alberto Marnetto] explains in a recent blog post, decompiling Stunt Island and poking around at the code allows one to improve the graphical detail level in the flight simulator by approximately 800%. In fact, it’s possible to go even higher, though at some point the game simply becomes unplayable.

Hackaday Links: October 20, 2024

When all else fails, there’s radio. Hurricane Helene’s path of destruction through Appalachia stripped away every shred of modern infrastructure in some areas, leaving millions of residents with no ability to reach out to family members or call for assistance, and depriving them of any news from the outside world. But radio seems to be carrying the day, with amateur radio operators and commercial broadcasters alike stepping up to the challenge.

Put More Korry In Your Flight Sim Switches

May 3, 2024 by Dan Maloney 20 Comments

Never underestimate how far some flight simulator aficionados will go with their builds. No detail is too small, and every aspect of the look and feel has to accurately reflect the real cockpit. As a case in point, check out these very realistic Korry buttons that [Santi Luib III] built for an Airbus A320 simulator.

Now, you might never have heard of a “Korry button” before, but chances are you’ve seen them, at least in photos of commercial or military aircraft cockpits. Korry is a manufacturer of switches and annunciators for the avionics industry, and the name has become shorthand for similar switches. They’ve got a very particular look and feel and are built to extremely high standards, as one hopes that anything going into a plane would be. That makes the real switches very expensive, far more so than even the most dedicated homebrew sim builder would be comfortable with.

That’s where [Santi] comes in. His replica Korry buttons are built from off-the-shelf parts like LEDs and switches mounted to custom PCBs. The PCB was designed for either momentary or latching switches, and can support multiple LEDs in different colors. The assembled PCBs snap into 3D printed enclosures with dividers to keep light from bleeding through from one legend to the other.

The lenses are laser-cut translucent acrylic painted with urethane paint before the legends are engraved with a laser. The attention to detail on the labels is impressive. [Santi]’s process, which includes multiple coats of sealers, gets them looking just right. Even the LEDs are carefully selected: blue LEDs are too bright and aren’t quite the proper shade, so [Santi] uses white LEDs that are dimmed down with a bigger resistor and a light blue photographic gel to get the tint just right.

These buttons are just beautiful, and seeing a panel full of them with the proper back-lighting must be pretty thrilling. If civil aviation isn’t your thing, check out this A-10 “Warthog” cockpit sim, and the cool switches needed to make it just right.

Car Driving Simulators For Students, Or: When Simulators Make Sense

February 21, 2024 by Maya Posch 69 Comments

There are many benefits to learning to fly an airplane, drive a racing car, or operate some complex piece of machinery. Ideally, you’d do so in a perfectly safe environment, even when the instructor decides to flip on a number of disaster options and you find your method of transportation careening towards the ground, or the refinery column you’re monitoring indicating that it’s mere seconds away from going critical and wiping out itself and half the refinery with it.

Still, we send inexperienced drivers in cars onto the roads each day as they either work towards getting their driving license, or have passed their driving exam and are working towards gaining experience. It is this inexperience with dangerous situations and tendency to underestimate them which is among the primary factors why new teenage drivers are much more likely to end up in crashes, with the 16-19 age group having a fatal crash nearly three times as high as drivers aged 20 and up.

After an initial surge in car driving simulators being used for students during the 1950s and 1960s, it now appears that we might see them return in a modern format.

Bench Power Supply Turned Realistic Flight Sim Panel

August 12, 2023 by Tom Nardi No comments

Flight simulator software has been available for about as long as desktop PCs have been a thing, but modern incarnations such as 2020’s Microsoft Flight Simulator have really raised the bar — not only graphically, but in terms of interactivity. There’s a dizzying array of switches and buttons that you can fiddle with in your aircraft’s virtual cockpit, but doing it with the same keyboard that you use to hammer out code or write Hackaday articles doesn’t do much for immersion.

Looking to improve on the situation without having to shell out for an expensive sim panel, [Michael Fitzmayer] decided to convert a broken Manson SSP-8160 lab power supply into a fairly good approximation of the KAP 140 autopilot system which is used in one of his favorite aircraft, the Pilatus PC-6 Turbo-Porter.

[Michael] gutted the piece of equipment pretty thoroughly, only leaving behind the case itself and the illuminated button panel on the front. The original displays were replaced with TM1637 seven-segment LEDs, and a pair of new rotary encoders are mounted where the stock knobs were. The whole show is run by a STM32F103 Blue Pill, which conveys the button pressing and knob spinning to the game by mimicking a USB Human Interface Device.

A fascia applied to the front of the power supply blocks the original text and labels, and really makes the finished unit look the part. [Michael] admits it’s not 100% accurate to the layout of the real hardware, but it’s certainly better than trying to enter heading and altitude information with the controller.

Oh that’s right, did we mention he’s actually using this on the Xbox Series S? While we generally see this sort of sim hardware hooked up to a tricked out gaming computer, we appreciate that he’s trying to bring some of that same experience to the console world. While the one-way communication of USB HID does bring with it some limitations — for example the hardware needs to be manually reset at the beginning of each flight to make sure the physical displays match what’s shown in the virtual cockpit– there’s still a lot of potential here.

For example, you could design and build your own flight yoke, pedals, and throttles rather than spending hundreds on a commercial version. It sounds like [Michael] is just getting started in the world of affordable console-based flight simulation, and we’re very eager to see where he goes from here.

Modular Keyboard And Custom Game Controller

June 20, 2023 by Bryan Cockfield 3 Comments

Most video games, whether on console or PC, have standardized around either a keyboard and mouse or an analog controller of some sort, with very little differences between various offerings from the likes of Sony, Microsoft, Nintendo, or even Valve. This will get most of us through almost all video games, but for those looking to take their gameplay up a notch or who are playing much more complex games, certain specialized controllers are available, but they might not meet everyone’s specific needs. Thanks to this custom, modular keyboard anyone should be able to make exactly the controller they need.

The device features a grid of 15 interfaces where modules like buttons, potentiometers, encoders, and joysticks can be placed. Each module can be customized to a significant extent on their own, and they can be placed anywhere on the grid. The modules themselves can be assigned to trigger keyboard presses or gamepad motions depending on the needs of the user. A Raspberry Pi handles the inputs and translates them to the computer, so in that regard it functions no differently than a standard keyboard or gamepad would. Programming is done by sending commands via a USB serial port, with the ability to save various configurations as well.

The modular controller is open-source in terms of hardware and software, with easy assembly using through-hole components and a customizable 3D printed cover for anyone looking to make their own. The project’s creator [Daniel] had flight simulators in mind when designing the device, which often benefit from having more specialized controllers, but any game with lots of specific inputs from Starcraft to League of Legends could benefit from a custom controller or keyboard like this. Flight simulators are more often the targets of specialized and unique controls, though, like this custom yoke or this physical control panel.

Flight Simulator Focuses On The Other Side Of The Cockpit Door

October 25, 2022 by Dan Maloney 22 Comments

When one thinks of getting into a flight simulator, one assumes that it’ll be from the pilot’s point of view. But this alternative flight simulator takes a different tack, by letting you live out your air travel fantasies from the passenger’s point of view.

Those of you looking for a full-motion simulation of the passenger cabin experience will be disappointed, as [Alex Shakespeare] — we assume no relation — has built a minimal airliner cabin for this simulator. That makes sense, though; ideally, an airline pilot aims to provide passengers with as dull a ride as possible. Where a flight is at its most exciting, and what [Alex] captures nicely here, is the final approach to your destination, when the airport and its surrounding environs finally come into view after a long time staring at clouds. This is done by mounting an LCD monitor outside the window of a reasonable facsimile of an airliner cabin, complete with a row of seats. A control panel that originally lived in an airliner cockpit serves to select video of approaches to airports in various exotic destinations, like Las Vegas. The video is played by a Pi Zero, while an ESP32 takes care of controlling the lights, fans, and attendant call buttons in the quite realistic-looking overhead panel. Extra points for the button that plays the Ryanair arrival jingle.

[Alex]’s simulator is impressively complete, if somewhat puzzling in conception. We don’t judge, though, and it looks like it might be fun for visitors, especially when the drinks cart comes by.
