When you hear the term Tricorder, you might think of Star Trek but I assure you, this is no toy prop. Keeping with the same concept of the Tricorder used on the TV show the Tricorder is about reading data, _lots_ of data. And that is what the Tricorder project aims to do, develop handheld devices that are fitted with lots of diverse sensors in order to observe them.
So far the project has produced a few different versions. The Mark 1, the Mark 2, etc. They are currently working on the Mark 5. Each version is pretty different from the other, and they all contain a wide variety of sensors such as atmospheric temperature, humidity, pressure and electromagnetic field, color, infra-red. And the obvious like GPS. They’re even working on developing their own sensors like this 3d printable mini spectrometer.
The project is open, and there are tons of pictures, and schematics on the tricorderproject’s web site.

With the help of “Because We Can”, creator fungus amungus made his own Skee Ball Machine. The game was built from 3/4″ plywood cut to shape on a ShopBot. Everything appears to fit together like a puzzle with a few screws to secure the parts.
The brains of the game is hosted on an Arduino UNO and it uses 5cm Optical Distance Sensors to detect when the balls go through the holes. The traditional rules were tweaked a little to include among other things the ability to score bonus points for combos.
Check out the video and links above for more details.

Think your iPhone 5S TouchID is secure? Think again. The biometrics hacking team of the Chaos Computer Club (CCC) has successfully bypassed the biometric security of Apple’s TouchID using the How to fake a fingerprints? process they wrote about back in 2004.
“First, the fingerprint of the enroled user is photographed with 2400 dpi resolution. The resulting image is then cleaned up, inverted and laser printed with 1200 dpi onto transparent sheet with a thick toner setting. Finally, pink latex milk or white woodglue is smeared into the pattern created by the toner onto the transparent sheet. After it cures, the thin latex sheet is lifted from the sheet, breathed on to make it a tiny bit moist and then placed onto the sensor to unlock the phone. This process has been used with minor refinements and variations against the vast majority of fingerprint sensors on the market.”
Nothing good could ever come from storing your fingerprints on your smartphone. Just don’t do it people! You can read more about the iPhone 5s TouchID Hack here.

The Electric Imp is a WIFI module with a brain. In some use cases it’s used to help connect your device to the cloud, as one of those ‘internet of things’. On other cases (like this one), it is the thing. Marcus has a cool little project that takes temperature readings and pushes them to the cloud.
Since the Imp is pretty power savvy, Marcus was able to power the project using a solar panel and charger. From there it uses a TMP36 analog temperature module to pull readings from. The temperature is read using the ADC and turned into an actual temperature number. The imp handles the rest by using the ThingSpeak api, which then collects and graphs the data.
