An "Internet of Things" starts with temp/motion sensors like these Wireless Sensor Tags from Cao Gadgets

Imagine an "Internet of Things" where even the smallest device could store and report information about itself or whatever it is attache to. These Wireless Sensor Tags are a big step in that direction. These small devices can be attached to doors, windows, mailboxes, keys..almost anything actually…and then report back to you -- via web, smartphone, SMS, etc -- whenever they are moved or whenever temperatures exceed programmed minimums.

For myself, I could see putting one of these in my mailbox so I could tell when the mail had arrived or placing one on the garden gate so I would know when the meter readers (or others) had entered my back yard. You can probably come up with a hundred different uses for these devices and the web site has a host of ideas (and video demonstrations) to get you started.

You can also use the Wireless Sensor Tag to let you know where something is in your home -- like the TV remote, keys or whatever else you have a habit of misplacing. You can use your smartphone or PC to tell the device to start beeping so you can hunt it down.

The Ethernet Tag Manager (which plugs into your network) and 3 tags will set you back about $91 when purchased together.

Elsewhere Online: AT&T's Spam Filter Gets A Bit Too Aggressive

This story from TechDirt lays out yet another reason I recommend that folks DON'T use the email provided to them by their ISP. My typical recommendation right now is to get a Gmail account instead. It also points out why I want to manage all my SPAM on my end, without pre-filtering from an ISP. I will gladly manage my spam if it helps to insure that I see as many of my "real" messages as possible. Again, Gmail's tools work pretty good in this regard. Having an alternative email account also insures you will keep the same email, even if you decide to leave your current ISP. Witness all the folks holding onto AOL accounts just to keep their AOL email address. Thank goodness at least that is free now. AT&T's Spam Filter Gets A Bit Too Aggressive You can certainly understand why ISPs offer spam filters. It's a service for users who don't want to be totally bombarded with spam. But what I've never understood is that these ISPs rarely give the user a

On my iPhone…IFTTT (If This Then That) for iOS

IFTTT (If This Then That) for iOS IFTTT (If This Then That) for iOS My best description of IFTTT, both their main web site, and this new iOS app is "a scripting language for the We." It allows you to set up "recipes" that watch one particular service, like Feedly, Evernote, Gmail and more, and then take action on another service whenever a particular action occurs. I use this to automatically save my shared items from Feedly and elsewhere into an Evernote Notebook and also use it to post automatically post information on a variety of services. The iOS app adds to this functionality by allowing you to take various actions on your phone and triggering IFTTT actions whenever they occur. In the case of the iPhone, initiating actions can include adding new contacts to your iPhone, taking a new picture and more.  For more complete information on how IFFTT works, visit    From the iTunes App Store...

This DIY domino clock tells the time using three LED-lit tiles via Arduino Blog

After coming across Carbon Design Group’s Domino Wall Clock, which uses electronic magnetic coil motors to reveal white dots, Instructables member “Kothe” decided to create a simplified version of their own. The clock is comprised of three custom dominoes — the first tile for hours, the second and third for minutes. Unlike its inspiration, Kothe’s device uses addressable RGB LEDs as dots that allow for a variety of colors to shine through.
