The one thing that separates the pros on Twitch from the dilettantes is the production values. It’s all about the smooth transitions, and you’ll never catch the big names fiddling with dodgy software mid-stream. The key to achieving this is by having a streamdeck to help control your setup, like this straightforward design from [Electronoobs]. (Video, embedded below.)

The build relies on an Arduino Micro, which is a microcontroller board perfectly equipped to acting as a USB macro keyboard. It’s paired with a Nextion LCD touchscreen that displays buttons for various stream control features, like displaying a “Be Right Back” screen or cuing up video clips. The build also features bigger regular buttons for important quick-access features like muting a mic. It’s all wrapped up in a 3D printed housing, with some addressable RGB LEDs running off another Arduino to add some pizazz. The neat trick is that the build sends keycodes for F13-F24, which allows for the streamdeck’s hotkeys to avoid conflicting with any other software using conventional keyboard hotkeys.

It’s a useful tool that would be of use to anyone streaming on Twitch or other platforms. Alternatively, you could repurpose an old phone to do a similar job. Video after the break.

Ah, the joys of domestic animals. Often adorable, occasionally useful, they’re universally unable to care for themselves in the slightest. That’s part of the bargain though; we take over responsibility for their upkeep and they repay us with whatever it is they do best. Unless the animal in question is a cat, of course – they have their own terms and conditions.

Chickens, though, are very useful indeed. Give them food and water and they give you delicious, nutritious, high-quality protein. Feeding them every day can be a chore, though, unless you automate the task. This Twitch-enabled robotic chicken feeder may be overkill for that simple use case, but as [Sean Hodgins] tell it, there’s a method to all the hardware he threw at this build. That would include a custom-welded steel frame holding a solar panel and batteries, a huge LED matrix display, a Raspberry Pi and camera, and of course, food dispensers. Those are of the kind once used to dispense candy or gum for a coin or two in the grocery; retooled with 3D-printed parts, the dispensers now eject a small scoop of feed whenever someone watching a Twitch stream decides to donate to the farm that’s hosting the system. You can see the build below in detail, or just pop over to Sweet Farm to check out the live feed and gawk at some chickens.

It’s an impressive bit of work on [Sean]’s part for sure, and we did notice how he used his HCC rapid prototyping module to speed up development. Still, we’re not convinced there will be many donations at $10 a pop. Then again, dropping donations to the micropayment level may lead to overfed chickens, and that’s not a good thing.

When the Golf GTI and the Jetta GLI were born, Volkswagen packed both with turbocharged engines, precision performance, and a whole lot of vroom. But aside from their stylish exteriors, a rivalry between the vehicles was forged. And, what better way to settle this rivalry than with a massive RC car race on a custom, Tron-like track?

As part of their “Rival Road: GTI vs. GLI” virtual experience, Volkswagen built a giant 1,800 square-foot track equipped with illuminated walls, low-polygon-looking mountains, and nine Arduino-powered obstacles (connected to a laser-etched control panel) that are activated by viewers on Twitch. These barriers include everything from a turntable that spins the cars around, to whack-a-mole-style pillars that pop up randomly, to rumble strips.

From July 26-27th, fans can tune in to the live stream to support their favorite team and vote on the obstacles that’ll be raised from the track to thwart opponents. The RC Golf GTI and Jetta GLI vehicles will be operated by professional RC drivers Tanner Foust and Scott Speed.

Pretty sweet, right? Jalopnik had the chance to get a firsthand look at the project, where Volkswagen showed off everything from how it was made to how it works.
