TV-B-Gone v1.2 Kit - Shut-off any TV

The TV-B-Gone Kit is an awesome little gadget. Whit it, you can turn off any TV! Yep, any TV.
The latest is the v1.2 of the kit, which has been updated with the shutdown codes of 230 different TV manufacturers and models, that practically covers every type of TV we come across.

The device is pretty simple: it fits in one hand, and just one button to press. Once you press, it cycles through the list of shutdown codes for TVs, starting from more common ones. It takes about a minute to cycle through all the codes. So, just press the button once, release, and keep holding it in the direction of the TV until it shuts off. For most TVs I tested, it only took couple of seconds to shut off.

It runs on just 2 AA batteries

The kit has 4 IR LEDs - 2 narrow beam long-range ones, and 2 wide beam ones. With 2 full batteries, it has a range of about 40 meters. It only needs 2 AA batteries.

You can even turn on a TV with it!
Click once to turn off, and once again to turn back on.

Amazon Echo Dot - 2nd Generation

You all know the Amazon Echo right? the voice-controlled smart speaker from Amazon, which connects to Amazon's Alexa service (the artificial intelligence personal assistant service). It has so many cool features. But, the price tag does make people reluctant to try it out. That's where Echo Dot comes in. It's less than one third of the price of the Echo. But don't let the lower price fool you - the Echo Dot has all the functionality of the Echo.

Echo Dot is now in its 2nd Generation (released on October, 2016). It's speaker is not as powerful as the one in the Echo, but still capable of covering a small room. If that sound is not enough, there's a 3.5mm Audio Jack in the Dot to connect it to an external audio system. Or, you can also connect it to a Bluetooth speaker.

The Echo Dot has 7 microphones built-in, and uses the "far-field voice recognition" technology to recognize commands even in a noisy environment. What if you have more than one Echo Dot within the range of your voice? The new Echo Spatial Perception (ESP for short) will make sure that the Dot that's closest to you will only respond.

Get your Echo Dot from here at Amazon.com.

I'll do a more hands-on review of my Echo Dot next.
