Introducing The Shapeoko 2

October 21, 2013 by Brian Benchoff 39 Comments

For all the 3D printers that hit the Hackaday tip line, it’s surprising we don’t see more CNC routers. They’re arguably more useful tools, and with the ability to mill wood, plastic, and non-ferrous metals, open up the door to a whole bunch more potential builds. One of the most popular – and certainly one of the least expensive – CNC routers out there, the Shapeoko, just received a huge update that makes this minimal machine even more capable.

The new Shapeoko 2 keeps the same V wheel on an aluminium extrusion design with Makerslide, but fixes a few problems that limited the original Shapeoko. There’s a larger work area on this version, and the Y axes feature dual stepper motors. The biggest feature, we think, is the ability to handle materials larger than the machine itself thanks to its open front and back.

The Shapeoko 2 is available in two versions, a $300 mechanical kit that requires you to go out and get some motors, a power supply, and a grblShield, the full version, for $650, includes everything you’ll need to start routing wood metal and plastic at home.

CastAR Goes Live On Kickstarter

October 15, 2013 by Adam Fabio 53 Comments

castar2
[Jeri, Rick and the Technical Illusions crew] have taken the castAR to Kickstarter. We’ve covered castAR a couple of times in the past, but the Kickstarter includes a few new features just ripe for the hacking. First, castAR is no longer confined to a retro-reflective surface. In fact, it’s no longer confined to augmented reality. An optional clip on adapter converts castAR into a “free” augmented reality or a full virtual reality system.

[Jeri] has also posted a video on her YouTube channel detailing the entire saga of castAR’s development (embedded after the jump). The video has a real “heart to heart” feel to it, and is definitely worth watching. The story starts with the early days (and late nights) [Rick] and [Jeri] spent at Valve. She goes through the split with Valve and how the two set up a lab in [Rick’s] living room. [Jeri] also outlines some of the technical aspects of the system. She explains how the optics have been reduced from several pounds of projectors to the mere ounces we see today.

Another surprise addition is the lower level tier rewards of the campaign. The castAR tracking system is offered. The campaign page says the tracking system can be mounted to anything from robots to other VR headsets. The possibilities for hacking are almost endless. We’re curious about setting up our own swarm of quadcopters similar to the UPENN Grasp Lab. The RFID tracking grid is also offered as a separate option. In the gaming system this will be used for tracking tabletop game pieces. Based upon the Kickstarter page, it sounds as if the grid will not only use RFID, but a camera based tracking system. We’re definitely curious what possibilities this will hold.

As of this writing, the castAR Kickstarter campaign is already well past the halfway mark on its way to a $400,000 USD goal.

GE Garage And Chicago Ideas Week

October 12, 2013 by Todd Harrison 4 Comments

I’ve been on vacation and managed to get a day to play at the GE Garage mobile fab lab currently setup in downtown Chicago. GE has partnered with Chicago Ideas Week to bring the future of fabrication technologies to a space where the community can walk in off the street and work with some amazing hardware like CNC mills, laser cutters and 3D printers. The group is also giving classes at select times on using the equipment and general electrics. Unfortunately I was in town near the end of this event which will be Oct 20th. If you are in the area I do recommend jumping on the excellent transportation you’ll find in Chicago and have some fun at the space. Here are more details on location, classes and times.

I didn’t expect to squeeze any work into my vacation but I did take a guided tour of the fab space with my iPhone 5s. You can join me after the break to watch the tour, which is a bit rough but still covers a lot of fun topics. Get at look at their line-up or Replicator 2 3D printers. See some fantastic prints from metal made on industrial scale printers. Learn more about the up-scaled CNC seen above that was cutting out skateboard decks. And finish up with an injection molding machine.

Hackaday Is Broken

October 8, 2013 by Mike Szczys 53 Comments

hackaday-mister-yuck We’re sorry for the page styling problems. This seems to be caused by a server-side upgrade issue — our incomplete stylesheet depended on another that just changed and broke everything. We’re trying to do a roll-back which will give us time to fix our theme. Thanks for your understanding. Feel free to unleash your rage in the comments below ;-)

Pro Tip (or should that be a website fail tip?): Hit CTRL-A (select all) in order to read the white text on white background comments below.

Update: Things look mostly back to normal again. Sorry again for the troubles…. but I’m actually having some fun reading the comments on this one!

Boston Dynamics Takes WildCat Outside

October 5, 2013 by Adam Fabio 62 Comments

wildcat

[Boston Dynamics] has released a video of their latest robot, which means it’s time to go hide in bed before this thing comes to get us. The new video features WildCat, which is apparently the evolution of the Cheetah robot we saw last year. Cheetah was an indoor cat, tethered by power, data, and hydraulic lines while running on a treadmill. WildCat has been released to ~~terrorize people~~ explore the great outdoors

Reminiscent of the early videos of BigDog, WildCat is currently powered by an internal combustion engine. The engine drives a hydraulic system, which then actuates the robot’s legs and front/rear pods. The beauty of a system like this is that switching to an electric motor is simple – just replace the IC engine. While we’re sure this would make a much more stealthy cat, weight and run time could be issues. Moving the power system onboard has also slowed down WildCat a bit. Cheetah was able to reach 28 MPH while WildCat can only muster 16 MPH.

WildCat is part of DARPA’s maximum mobility and manipulation program. The research appears to be focused on improving the gaits the robot uses to move at various speeds. The video highlights both bounding and galloping. Slo-mo sections show all four of WildCat’s legs leaving the ground, which is the suspension phase of a classic gallop gait. Control isn’t perfect yet, as WildCat tumbles at one point in the video. It gets right back up though – ready for more.

Tre: When Arduino Meets Beagle Bone

October 4, 2013 by Brian Benchoff 35 Comments

Although yesterday saw the announcement of an x86-based Arduino powered by an Intel chip. This may have not been the big story to come from [Massimo] at Maker Faire Rome. Announced along with the x86 Arduino Galileo was the Arduino TRE, a collaboration between Arduino and the BeagleBoard foundation.

The TRE is really two Arduinos in one: in the center is basically an Arduino Leonardo with the standard Arduino headers and an ATmega32u4. Elsewhere on the board is a TI Sitara ARM Cortex A-8 processor running at 1GHz with 512 MB of RAM, 10/100 Ethernet, HDMI out, USB host and device ports, and a bunch of connectors intended for an LCD and a ZigBee.

There is, of course, the obvious comparison between the TRE and Raspberry Pi. Hardware-wise, the TRE is very close to the BeagleBone Black, a bit more powerful than the Raspberry Pi, and able to do some very cool stuff (i.e. OpenCV) the Pi just can’t handle.

There is – I think – no official price for the Arduino TRE quite yet. It will be available in spring, 2014, though. You can check out all the press release photos in the gallery below.

Make The World Takes On Crowdsourcing Prosthetics

Tonight marks the launch of a new program from Adafruit focused on improving the availability of prosthetic designs. The program will be highlighted in four Google+ Hangouts over the coming month. Mark your calendars for 8pm Eastern Time to join in on the one-hour launch.

We’ve seen a fair number of prosthetic hacks over the years, and every time one is featured we try to drive home the importance of sharing information in order to build upon the advances of others. The power of this is clear, shown in a $150 3D printed hand for a child, hackers that are replacing their own limbs or digits, and the sharing of diy fabrication techniques to help bring prostheses to the developing world. So get excited, get involved, and get hacking!
