Vayyer’s 3D Sensors for home applications, sensors that see through walls

Sensors could also be utilized for advanced security and safety features in case of fire or intruder. AlertTracks the real-time movement of individuals inside the home and pinpoints and locates people in a structural fire or if home security has been breached.

Their web site does not  yet reveal much about what their technology is about. Presumably their technology uses low power wireless signals with powerful software to interpret reflections. This would enable them to provide a “3D sensor” that sees through walls, providing position information. Perhaps like Kinect but using wireless RF signals.

If my interpretation is correct, this technology could have many useful applications in construction, repair and perhaps even imaging of humans.

Update: A separate tech article from a year ago, describing a product that uses Vayyar technology, suggests the above is exactly what this is about. Basically, this is a low power radar imaging system technology.

The Internet of Things is all about sensors, data collection, data analysis, and actuators/stepper motors and what not. The Vayyar technology adds a new capability to sensing by seeing through surfaces in 3D.

Hacking embedded systems: Camera hacking the Canon PowerShots

Source: CHDK Wiki | Fandom powered by Wikia

If you have a Canon PowerShot camera, a great and fun software hack is available – for free – called the Canon Hack Development Kit or just CHDK.

CHDK is software that runs on your Canon PowerShot camera to add additional features and capabilities; which features are supported depends on which PowerShot camera is used.

When I had a Canon PowerShot SX1, I used CHDK especially for its motion detection feature. This hack added a feature to detect motion in a scene and then fire the shutter – which was perfect for photographing lightning. Yes, its detection is so fast that you could use it to photograph lightning bolts.

In addition to a set of features added by CHDK to the PowerShot cameras, CHDK also adds “scripting”. This is a feature that let’s you write a set of commands (similar to writing a program) to use and operate various camera features.

The hack is installed by copying files to a specially prepared mini SD card. When the camera is turned on, the hack software is pre-loaded, together with the camera’s own, original software.

I sold my SX1 (a great camera for macro shots due to its macro feature and small sensor size). Since then, I have missed being able to play with CHDK. I am thinking about buying a used Powershot with a larger 1/1.7″ sensor so I can play with CHDK again 🙂

How to save your Instagram photos and then delete your account

In light of Instagram’s new policy to license out user’s photos for ads, without specific permission or compensation, users are canceling their Instagram accounts in droves: Oh My Tech!: How to delete your Instagram account | The Salt Lake Tribune.

Many are switching to the Flickr.com, which now includes an iPhone photo sharing app.

Update: Instagram co-founder wrote a blog post suggesting they messed up their new terms of service and will make unspecified changes.
