[Dave] found an affordable 4-channel R/C controller in the Bezos Barn and did just that. It took some modifications to make it work, like making a daughter board to turn the thumb grip input from a toggle button to a momentary and figuring out what to do with the three-way slider switch, but it looks like a blast to use.

The controller comes in a 6-channel version with two pots on the top. Both versions have the same enclosure and PCB, so [Dave] already had the placement molded out for him when he decided to install a pair of momentary buttons up there. These change roles based on the three-way slider position, which switches between race mode, menu mode, and extras mode.

We love the way [Dave] turned the original receiver into a USB dongle that emulates an Xbox 360 controller — he made a DIY Arduino Pro Micro with a male USB-A, stripped down the receiver board, and wired them together. There’s an entire separate blog post about that, and everything else you’d need to make your own R/C controller is on GitHub. Check out the demo and overview of the controls after the break.

[Dave] is no stranger to making game controllers — we featured his DJ Hero controller modified to play Spin Rhythm XD a few months ago.

It’s been said that the best way to tackle the issue of childhood obesity would be to hook those children’s video game consoles up to a pedal-powered generator. Of course, this was said by [Alex], the creator of Cykill. Cykill interfaces an Xbox to an exercise bike, so to keep the video game going you’ll have to keep pedaling the bike.

While there is no generator involved in this project, it does mimic the effect of powering electronics from a one. The exercise bike has a set of communications wires, which are connected to a relay on the Xbox’s power plug. When the relay notices that the bike isn’t being pedaled enough, it automatically cuts power to the console. Of course, the risk of corrupting a hard drive is high with this method, but that only serves to increase the motivation to continue pedaling.

The project goes even further in order to eliminate temptation to bypass the bike. [Alex] super-glued the plug of the Xbox to the relay, making it extremely difficult to get around the exercise requirement. If you’re after usable energy instead of a daily workout, though, there are bikes out there that can power just about any piece of machinery you can imagine.

If one could temporarily remove their sense of humor and cast a serious look into a Rube Goldberg machine, they would not say to themselves “well that looks simple.” Indeed, it would almost always be the case that one would find themselves asking “why all the complexity for such a simple task?”

Too often in hacking are we guilty of making things more complicated than they really need to be. Maybe it’s because we can see many different paths to a single destination. Maybe it’s because we want to explore a specific path, even though we know it might be a little harder to tread. Maybe it’s just because we can.

But imagine approaching a hack as simply a means to an end. Imagine if you did not have all of that knowledge in your head. All of those tools at your disposal. How would this change your approach? When [yavin427] decided to automate the leveling up process in his favorite video game, odds are he had never taken a game controller apart. Had never touched an oscilloscope. Indeed, he might have no knowledge of what a transistor or microcontroller even is. While many of our readers would have taken the more difficult path and tapped directly into the TTL of the controller to achieve maximum efficiency; it is most likely that [yavin427] would not have known how to do this, and thus would not have seen the many other paths to his end goal that would have been obvious to us. Yet he achieved his end goal. And he did it far easier and with less complication than many of us would have done.

Thoughts?

It sounds like [Andrew] is trying to build a Pavlovian response into his behavior when it comes to online gaming. He wants to make sure he doesn’t miss out when all his friends are online, so he built this traffic signal to monitor Xbox Live activity. It will illuminate the lights, and drive the meters differently based on which of his friends are currently online. When the light’s green, he drops everything a grabs a controller.

The base of the light is a black project box. Inside you’ll find the Arduino compatible chip which drives the device mounted on a piece of protoboard. A WIZnet W5100 adds network connectivity at the low price of around $25. There is one problem with the setup. The API which [Andrew] found doesn’t use any authentication. This means that he can only see the public status of his friends; anyone who has set their online status set to private will always register as ‘online’. If you know of an existing Xbox Live API that would solve this issue we’d love to hear from you in the comments.
