[Paul] wrote in to submit this video introduction to the Xin Che Jian hackerspace in Shanghai. It appears as though they have a fairly active space there, with several ongoing projects. They show off a range of things from an intelligent wireless power strip to aquaponics. The space seems to have the usual amenities such as project storage and a machine shop. The familiar sound of someone explaining that several of the tools are “almost working” reminds us that it is a small world, and we’re all pretty much the same.

Tank Router Defends Your Pets?
The guys over at Section9 Hackerspace in Springfield, Missouri just finished building this treaded robot. Despite the juxtaposition of the cat, it really doesn’t defend anything. The project is a reconnaissance robot controlled over the network with video feedback.
The team started off with some lofty goals. They wanted to the robot to be able to climb stairs and to feature a detachable flying portion in order to get a better look at hard to reach places. Cost and complexity are cited as the reasons they ditched the idea of the flyer. The rest of the features came out much as planned. The motor controller for the treads is connected to an Arduino. This uses an Ethernet shield to connect to the WRT54G router which is also coming along for the ride. This seems a bit over-powered but it makes it easy to connect the webcam on the front (also via Ethernet).
On the software side they wrote an Android app. It controls the movement of the robot, as well as that of the camera. Of course you need to see where you’re going so they went the extra mile to include video from the webcam. Check out their show-and-tell video after the break.
Hackerspace Grand Opening Tonight In Portsmouth NH
The Port City hackerspace will be opening its doors tonight at 7pm for their grand opening party. Judging from the pictures on their site, they’ve actually had the space long enough to get the tools set up and even do a few projects. This should be a good way to jump start the membership though. Like most hackerspaces should, they are offering classes to people to educate them on the use of the tools and proper safety.
They have the usual full shop, but they also have a designated bike shop, where they will have several custom bikes on display. If you’re in the area, you should be sure to swing by and check it out. You are assured to at least get some delicious bar-b-que out of the deal.
Southwest Tour: Fablab In Tulsa Oklahoma
We passed through Tulsa Oklahoma the first day we were traveling, but it was very early in the morning, so we skipped the Fablab. On the way home though, the timing was perfect for a quick visit. [Blixa] was happy to show me around and explain how the fablab works.
Back Up The Band With Some RGB Stage Lights
Fresh off the 72-hour madness of the Red Bull Creation contest some of the folks a North Street Labs took on a stage lighting project. It’s for a local performing venue that just opened up, and despite the time crunch the team pulled off another great build.
Sixteen meters of LED strip make the electronics for the project a whole lot easier. The strips run up the center of a cabinets built as stand-alone columns which will end up at the back of the stage. Each cabinet has its own 5V 4A power supply (note the burnout issues they mention when using cheap eBay PSUs). Each column has its own Arduino Uno driving the LEDs, with an RS485 shield to connect back to a main Arduino Mega 2560 controller. It uses a PSX controller to switch between different lighting modes.
The seven towers boasting 688 LEDs isn’t all that’s shedding light on the show. There’s also about 300 feet of EL wire at work.

Fauxrarri Is The PPPRS Champion
The Power Racing Series (PPPRS) is an electric vehicle competition with a $500 price ceiling. This is Fauxarri, the 2012 Champion. It was built by members of Sector67, a Madison, WI hackerspace. To our delight, they’ve posted an expose on the how the thing was built.
It should come as no surprise that the guys behind the advance electric racer aren’t doing this sort of thing for the first time. A couple of them were involved in Formula Hybrid Racing at the University of Wisconsin. That experience shows in the custom motor controller built as an Arduino shield. It includes control over acceleration rate, throttle response, and regenerative braking. But you can’t get by on a controller alone. The motors they used are some special electric garden tractor motors to which they added their own water cooling system.
If you want to get a good look at how fast and powerful this thing is head on over to the post about the KC leg of PPPRS (it’s the one towing a second vehicle and still passing the competition by).
Southwest Tour: [Mikey Sklar’s] Homestead
While on our southwest tour, we were sure to make some time to go visit [Mikey Sklar]. He’s been a friend of hackaday for a long time, both as a writer and as someone who sends us cool projects. As you may have noticed from some of the posts we’ve done on his projects, [Mikey] lives in the middle of the desert and is attempting to lead a fairly self sustaining life style. He and [Wendy] showed us their gardens, the hot spring on their property,and some cool building materials they’ve utilized. We got to tour [Mikey’s] workshop and check out how his solar system was set up. It was pretty cool seeing “da Pimp” being used to revive old batteries. [Mikey] even mentioned that he’s building in a lot of safeguards in the next revision based on the feedback he got online.
What I really enjoyed about talking with [Mikey] and [Wendy] was that they didn’t act like they had it all figured out. They’re approaching this whole lifestyle as a learning adventure as you can hear when [Mikey] talks about their bees.
