Adding In-Game Reset To Classic Playstations

June 1, 2021 by 6 Comments

The first Playstation is quickly approaching three decades since its release, and while this might make some of us who were around for that event feel a little aged, the hardware inside these machines isn’t getting any younger either. Plenty of people are replacing the optical drive in the original hardware with an optical drive emulator as they begin to fail, and with that comes the option for several other modifications to the hardware like this in-game reset mod.

In-game reset is a function that allows a console to be reset via a controller button combination rather than pressing the console’s reset button directly. Especially for devices modified with either the XStation or PSIO drive emulators, this can be a handy feature to have as this method can more easily take the user back to the emulator menu as well as physically reset the device. The modification is a small PCB which attaches to the controller port and, unlike previous versions, only requires a single pin to be soldered to the Playstation’s control board.

If you’re someone who enjoys playing games on original hardware rather than a patchwork of emulators, this could be an excellent addition to your PS1 that still allows most of the original feel and experience the PS1 offered. The drive emulator can greatly expand the range of the hardware as well, much like this NES cartridge which similarly expands the capabilities of that much older system.

Street-Legalize Your Ebike With A Magnet

March 1, 2021 by 98 Comments

Getting into e-biking is a great hobby. It can get people on bikes who might otherwise not be physically able to ride, it can speed up commute times, and it can even make hauling lots of stuff possible and easy, not to mention it’s also fun and rewarding. That being said, there are a wide array of conflicting laws around what your e-bike can and can’t do on the road and if you don’t want to run afoul of the rules you may need a programmable device that ensures your e-bike is restricted in the appropriate way.

This build is specifically for Bafang mid drives, which can be up to 1000 W and easily power a bike beyond the speed limit where [Tomblarom] lives. A small microcontroller is housed in a waterproof box on the bike and wired between the motor’s display and controller. A small hall effect sensor and magnet sit by this microcontroller, and if the magnet is removed then the microcontroller reprograms the bike’s controller to limit the speed and also to disable the throttle, another feature that is illegal in some jurisdictions but not others. As an added bonus, the microcontroller also handles brake lights, turn signals, and automatic headlights for the bike as well.

While the project page mentions removing the magnet while getting pulled over to avoid fines and other punishments, that’s on you. We imagine this could still be useful for someone who wants to comply with local laws when riding on the road, but still wants to remove the restrictions when riding on private property or off-road where the wattage and speed restrictions might not apply.

Automated Balcony Shade Uses NFC

January 20, 2021 by 3 Comments

[Udi] lives in an apartment with a pleasant balcony. He also has three kids who are home most of the time now, so he finds himself spending a little more time out on the balcony than he used to. To upgrade his experience, he installed a completely custom shade controller to automatically open and close his sunshade as the day progresses.

Automatic motors for blinds and other shades are available for purchase, but [Udi]’s shade is too big for any of these small motors to work. Finding a large servo with a 2:1 gear ration was the first step, as well as creating a custom mount for it to attach to the sunshade. Once the mechanical situation was solved, he programmed an ESP32 to control the servo. The ESP32 originally had control buttons wired to it, but [Udi] eventually transitioned to NFC for limit switch capabilities and also implemented voice control for the build as well.

While not the first shade controller we’ve ever seen, this build does make excellent use of appropriate hardware and its built-in features and although we suppose it’s possible this could have been done with a 555 timer, the project came together very well, especially for [Ubi]’s first Arduino-compatible build. If you decide to replicate this build, though, make sure that your shade controller is rental-friendly if it needs to be.

Rhythm Game Controller Can’t Be Beat

January 7, 2021 by 5 Comments

There’s this whole class of vertically scrolling rhythm games that take both hands and look really fun to play, albeit hard on the joints. You can buy specialized controllers for them, but they’re ridiculously expensive for what they are — just a handful of switches and two knobs. It’s exactly the kind of thing you should build to your taste for far less money.

Inspired by a pocket version of the Voltex controller that is also pretty darned expensive, [OmniSaiRen] set out to make their own on the cheap by building an awesome little macro keyboard that’s smaller and easier to use than the specialized controller. Inside there’s an Arduino Pro Micro taking input from eight Cherry MX switches and two optical encoders. The game treats the encoders as vertical and horizontal mouse movements, so [OmniSaiRen]’s code scans the encoders for their positions.

[OmniSaiRen] wrote their own matrix code and says it’s ugly, but it works well enough to play the game. What more can you ask for? A cool sticker to go on the top? Done. It’s too cold outside to paint, anyway. If it’s a one-handed game pad you need, check out this sweet little thing.

Building A Smash Bros. Controller With Keyswitches

December 18, 2020 by 5 Comments

When it comes to competitive fighting games, having the right controller in your hands can make the difference between victory and defeat. Many tournaments have strict rules around controllers for this very reason. [Akaki Kuumeri] has recently put together a custom controller, aimed at maximising performance in Super Smash Brothers: Ultimate on the Nintendo Switch. (Video, embedded below.)

The build is assembled in an attractive 3D-printed body, made to be reminiscent of the original Nintendo Entertainment System controller. Inside, a cheap third-party Gamecube controller is used to interface with the console. Mechanical keyboard switches are used to replace the buttons and even the analog sticks, with a special modifier key that enables walking and running across the stage. This is pulled off with a handful of resistors emulating the intermediate position of the analog sticks, and makes pulling off advanced combos easier.

It’s a fun build, and we can imagine the precise digital key inputs having some benefits over analog controls. It also pays to note that such a build wouldn’t be as easy without the ready supply of mechanical key switches thanks to the custom keyboard subculture. We’ve seen these satisfying switches cropping up in many controller builds in recent times.

Console Controller Mod Gets Amputee Back In The Game

December 15, 2020 by 7 Comments

No matter how it happens, losing one or more fingers is going to change one’s life in thousands of ways. We’re a manipulative species, very much accustomed to interacting with the world through the amazing appendages at the ends of our arms. Finding ways around the problems that result from amputations is serious business, of course, even when it’s just modifying a game console controller for use with a prosthetic hand.

We’ve gotten to know [Ian Davis] quite well around these parts, at least from his videos and Instagram posts. [Ian]’s hard to miss — he’s in the “Missing Parts Club” as he puts it, consisting of those who’ve lost all or part of a limb, which he has addressed through his completely mechanical partial-hand prosthetic. As amazing as the mechanical linkages of that prosthetic are, he hasn’t regained full function, at least not to the degree required to fully use a modern game console controller, so he put a couple of servos and a Trinket to work to help.

An array of three buttons lies within easy reach of [Ian]’s OEM thumb. Button presses there are translated into servo movements that depress the original bumper buttons, which are especially unfriendly to his after-market anatomy. Everything rides in an SLA-printed case that’s glued atop the Playstation controller. [Ian] went through several design iterations and even played with the idea of supporting rapid fire at one point before settling on the final design shown in the video below.

It may not make him competitive again, but the system does let him get back in the game. And he’s quite open about his goal of getting his designs seen by people in a position to make them widely available to other amputees. Here’s hoping this helps.

Mouse-Controller Hybrid Aims To Dominate In First-Person Shooters

December 15, 2020 by 49 Comments

The first person shooter genre found its feet in the PC world, relying on the holy combination of the keyboard and mouse for input. Over time, consoles have refined their own version of the experience, and the gamepad has become familiar territory for many FPS fans. [Tech Yesterday] was a die hard controller player, but after trying out  a mouse, didn’t want to go back. Instead, he built a truly impressive hybrid device.

The build begins with a standard Xbox 360 wired controller, somewhat of a defacto standard for PC gamepads. The left analog stick and triggers remain untouched, however the face buttons are all relocated using mechanical keyboard switches. The D-pad has been relocated to the left hand side with tactile switches, and the right analog stick removed entirely. In its place, a cut-down optical mouse is used on a flat 4″x4″ mousepad attached to the controller, strapped to the player’s thumb.

The resulting controller combines the benefit of analog stick movement and the precision aiming of a mouse. We’re amazed at how comfortable the controller looks to use, particularly in the improved second revision. While currently only used on PC, we can imagine such controllers shaking up the console FPS scene in a serious way.

We see some great controller hacks around these parts; the force-feedback mouse is a particularly amusing example. Video after the break.
