Building A Controller For MMOs

July 25, 2012 by 34 Comments

It’s a simple fact of gaming that controllers are more suited for shooters, while the WASD + mouse control of the PC gaming master race is more suited for real-time strategy games and MMOs. [Gabriel] wanted to challenge this idea, so he put together a controller combining the best of a mouse and keyboard for some hand-held RTS and MMO action.

The Keyball Controller as [Gabe] calls it is an amazing amalgamation of a 3rd party XBox and PS3 controllers, an SNES controller, a trackball, two USB keyboards and a ton of Bondo. The front of the Keyball features a WASD D-pad, scroll wheel, trackball, tiny keyboard and a few other commonly used buttons. The rear of the controller is loaded down with tons of trigger buttons and a few meta buttons that alter the function of other buttons.

The fabrication of the controller is absolutely phenomenal and certainly something that deserves to be copied. We’ve seen some controllers duplicated with a silicone mold and resin, so we can only hope that [Gabe] is looking at RTV silicone at the moment.

Yet Another RepRap Host Looks Pretty Cool

July 25, 2012 by 9 Comments

Joining the pantheon of other RepRap host software packages such as ReplicatorG, RepSnapper, and Skeinforge is Yet Another RepRap Host, a project by [Arkadiusz] that combines a lot of neat features into a very cool package.

One thing we’ve really got to give [Arkadiusz] credit for is a virtual table that allows you to import several .STL files, place them on a virtual build platform, and print them all at once. Previously, the only way we knew how to do this was by either creating a single .STL file with all the desired parts already in place, or arraying several object to increase production. The virtual table feature allows anyone to bypass those steps and print out a lot of objects all at once.

YARRH also allows you to view the GCode in 3D. This feature is a little kludgy at the moment, but [Arkadiusz] says it’s functional and more than serviceable to run a 3D printer.

Right now, YARRH is only available for Windows, but a package for Ubuntu (and hopefully OS X) are coming down the pipe. You can check out some videos of YARRH in action after the break.

Remote Uploading To An Arduino With Codebender

A few weeks ago, we saw codebender, an online replacement for the Arduino IDE that allowed you to upload a sketch to your board from a web browser. Over on the codebender blog [Vasilis] and his team are rolling out a way to remotely upload code to an Arduino over Ethernet. Now you don’t even need a serial connection to program an Arduino; it can be done over the Internet to a board in the next room, or on another continent.

The star of this hack is the Ariadne bootloader, an implementation of TFTP that allows any Ethernet-enabled Arduino to receive updates over the Internet. There is still one small problem with the Ariadne bootloader: uploading code over Ethernet requires someone to press the reset button on the Arduino, completely negating the benefits of programming an Arduino over Ethernet.

This problem has been solved before for earlier Arduino boards, so we’re sure [Vasilis] and his team will be able to fix the reset issue in very short order. If you’d like to check out the remote TFTP bootloader and play around with codebender, you can grab Ariadne over on GitHub.

Ever wonder what CPU dev boards look like?

In the realm of highly confidential hardware, it doesn’t get much more secret than upcoming CPUs coming out of Intel. Somehow, a few CPU dev boards wound up on eBay, and [Leon] was cool enough to save all the pictures (Polish, Google translation, or translate in the sidebar). There are a few ongoing auctions right now, but we’d settle for this LGA 1156 breakout board. So cool.

No, we’re not linking directly to the free stuff

TI is giving away a brushless motor controller powered by a Stellaris ARM processor. [Chris] says he’s ordering one to figure out how to make a Stellaris dev board out of the giveaway. This controller is designed for e-bikes, so at the very least we see a few ginormous UAVs in someone’s future.

More rocket stuff!

One of [Bill]’s older hacks was taking a CVS disposable digital camera (remember that?) and stuffing it into the nose code of an Estes D-powered rocket. There’s a ton of videos of the flights [Bill] put up on YouTube.

On another note, [CyberPunk] built a half-scale model of a swing-wing rocket launched glider (pics: 1, 2, 3, 4). He’s currently building the full-size version capable of carrying RC and video gear and wants some feedback.

So, CAD on a tablet?

[spuder] caught wind of a tablet-based engineering notebook a few people are working on. They’re looking for some feedback on their demo video. We think it’s cool – especially the ability to share stuff between devices – but CAD on a tablet makes us extremely skeptical. Tell them what you think; we’d love to see this make it to our phone.

Now if they only made one for editing WordPress posts….

Test-driven development just got cooler. Here’s a Tamagotchi for Eclipse that you ‘feed’ by going from red to green and refactoring your code. Be careful, because having the same code test as red twice will kill your little code ninja.

And now I’ll rant about you.

A few days ago, I posted [Becky Stern]’s light-up handlebars project, and one comment surprised me. Who says guys can’t sew? It’s time to confront the gender roles that show up whenever sewing is used in a project. I’m doing a tutorial on how to sew a parachute, but I need your help. It’ll be a two-parter: one on how to actually use a sewing machine, and another for how to make a ‘chute. Is there anything else you’d like to see?

Raspberry Pi Keeps Tabs On Your Solar Power Setup

[Brian Dorey] has been adding green power solutions to his home for some time now, and as things have progressed, he has experimented with several different iterations of data loggers. The latest system watching over his solar power setup is a Raspberry Pi armed with a custom-built I2C analog/digital converter.

The Rasp Pi is responsible for monitoring several different temperature sensors related to his solar water heating and storage system, but that’s just the beginning. It also keeps watch over his roof-mounted solar electric panels, his battery bank, and its charge controller. For good measure, he also monitors his home’s temperature and his water tank’s recirculation pump because, why the heck not?

All of the collected data is relayed to his web server where it is handsomely displayed for his perusal and analysis. [Brian] has made his code available here, so you can monitor your home in the same fashion with little fuss.
