Hasta La Gadget!

Budding hobbyists almost have it too easy these days, what with all the ready-made components, Mindstorms and Arduino boards, but there’s still a couple of folks out there kicking it old-school… and printing transistors at home. Yes, that’s a RepRap 3D printer you see there, with a MakerBot Unicorn pen head, depositing tiny dots of silver ink to form intricate rows of tiny electrodes. Sadly, the printer doesn’t currently automate the entire process, as you’ll also need to separately apply a dielectric material and a host of chemicals to get a working field effect transistor from scratch, but once the basic process is perfected the possibilities, as they say, are endless. Now if you’ll excuse us, we’ve got a hot date with some vacuum tubes. Find the basic formula for DIY transistors at our source link.

We’ve been so wrapped up in Kinect hacks lately that we actually missed a Kinect non-hack that emerged last week. PrimeSense, who built the initial Project Natal reference hardware for Microsoft, has released its own open source drivers for the Kinect. PrimeSense is working with Willow Garage (best known for its open source ROS robot operating system), and Side-Kick (a motion gaming startup) through a new OpenNI organization it set up, and the trio will be combining their powers for good. The OpenNI framework will cover low-level hardware support (drivers for actual cameras and other sensors), and high-level visual tracking (turning your body into a 3D avatar that kicks ass in a virtual world). This should be a boon to an already vibrant Kinect hacking community, and if the video above is any indication, we aren’t far from Kinect-level interaction and gameplay on our lowly PCs.

You had to know the hacking community was going to have a field day with the Nook Color — a $249 Android Tablet hiding behind with a thin e-reader coating. Indeed it didn’t take long to get rooted nor for Android 2.2 to get installed on there, but that particular hack comes with an interesting potential side-effect: small-scale thermonuclear explosions. Enabling FroYo requires disabling the device’s battery monitoring process, the very one that would be responsible for shutting down the device before the cells start overheating and, ultimately, going critical. Yeah it’s unlikely, but it could happen. Meanwhile, another hack has enabled the Android Market, but those instructions begin with a very daunting warning: “Very smart people have failed at this. If the following instructions confuse you, you might want to wait until an easier method has been developed.”

And, thankfully, there might be a much easier way coming, with Barnes & Noble reportedly telling Smartphone Mag that Android 2.2 will be officially coming to the Nook Color in January. Yes, Android 2.3 is what’s happening, but this is still an exciting upgrade as it will finally also allow access to a traditional Android home screen and even enable the Android Market.

Update: Okay, cancel that order for an asbestos carrying case. One of the developers of the Nook Color root wrote in to let us know that there is a secondary temperature monitor which should keep things below the ignition point. Hack away — or just wait a month.

Update 2: Barnes & Noble PR just got back to us to reiterate that Nook Color’s own shop will begin adding apps in early 2011 and that there are currently no plans to enable Android Market. Move along, nothing to see here, folks.

[Thanks, Ryan]

For hackers, Clear must have known that its iSpot mobile hotspot would be hard to resist — $100 for the device contract-free plus unlimited WiMAX for $25 a month is a pretty insane deal, after all, and the only catch is that they try to lock non-iOS devices out of the action. Indeed, it took mere hours for unlocks to start coming out of the woodwork, but now it’s easier than ever: the developer of one of the original iSpot hacks has circled back to create a new unlock that requires nothing more than a couple link clicks while you’re on a machine connected to the hotspot. How is that possible? Turns out there’s a vulnerability that makes it possible to execute arbitrary commands on the iSpot through web code, and Clear hasn’t yet updated the firmware to patch it. On that note, the developer tells us that there are actually some iPads that aren’t able to connect to the iSpot without the hack, ostensibly because Apple is using some MAC addresses that the iSpot’s current firmware isn’t expecting — so ironically, you might need this “jailbreak” just to use the thing the way Clear intended. As always with these sorts of things, proceed with caution — we don’t have an iSpot lying around to try this ourselves, so let us know how it goes.
