HP launches rugged Chromebook 11 G4 Education Edition laptop from $199

Something of a curiosity when they launched, Chromebooks have eventually settled in as the leading computer for schools, recently outpacing Apple and Microsoft's efforts to keep the market under wraps. HP is tapping into that trend with its latest laptop running Google's Chrome OS, which is designed to deal with the rough-and-tumble conditions of the classroom.

Dubbed the Chromebook 11 G4 Education Edition, the notebook is most notable for its fully rugged construction, meeting the MIL-STD testing standards for durability. For instance, it can withstand drops of 70 centimeters (or roughly 28 inches), according to the company, thanks to co-molded rubber edges. It also features a spill-resistant keyboard to deal with clumsy children with drinks nearby.

Underneath the "bubble wrap" protecting it from schoolkids' not-so-gentle handling, the G4 Education Edition shares the basic spec philosophy of other Chromebooks: not much for not much money. According to SlashGear, you get an Intel Celeron N2840 processor, and it can be outfitted with up to 4GB of RAM and 64GB of built-in storage. The 11.6-inch display has a resolution of 1,366x768 and includes a 180-degree hinge that allows the screen to lay flat for easier collaboration between students.

HP says the G4 Education Edition will be available starting this month at a typical school-budget-friendly Chromebook starting price of $199, but it doesn't yet appear on the company's website.

Product review: Vinsic 20000mAh Smart Dual USB Port Slim Power Bank, External Battery Charger

When I shop for external batteries I always seek out those that have smart charging chip. This means it can charger any device at its optimal charge - Apple devices require 2A, most Android devices require 1A (note that the new Nexus phones do rapid charging at 2.4A when the phone battery is low).



To test if in fact this claim is supported I used a current meter and a resistor with 2A and 1A settings. As advertised both ports were able to deliver the rate advertised by the resister. 0.96A/5.13V delivered with 1A resistor, and 1.85A/5.06V delivered on 2A resistor (it is normal to see some loss due to inefficiencies such as heat loss). Attached are images showing the tests.



The battery has a large capacity (20,000mAh) and is fairly large: 6 3/8" x 3 1/4" x 1". It weighs 1 pound and 0.3 oz. It has two ports. Another feature I like is the digital display showing how much capacity the battery has remaining. The display comes on automatically when I charge, or I can see it at any time by pressing an icon next the display. This is external battery does not allow charge through (i.e. it cannot charge while being charged). I have been using this battery for just over 2 weeks as I write this review. It holds the charge quite well (very little loss when disconnected) and the rating to appears to be accurate.



I received this power bank for evaluation and review. It is a good one!

Product review: Ambient Weather WS-8600 Weather Station

We have been using weather stations for many years, for the last year we have been using Oregon Scientific weather station. Oregon Scientific is a pretty well known brand, so I thought it would be useful to compare Ambient and Oregon Scientific.



The most noticeable difference is the display. Oregon scientific has a black and white LED display, it runs on batteries and the display gets dimmer as the batteries get weak. Ambient weather station home base unit runs plugged into AC. It has a bright digital display with a large choice of colors: red, green, blue, yellow and each color has different shades (for example, blue is dark blue or cyan). The visibility of the display is terrific, however if you are keeping the weather station in the bedroom it does generate quite a bit of light in the room. I came up with a solution for this by making it a "night hood" (you can see in my video) it is a square piece of felt which with glued edges that I put on it during the night. I remove it every morning and keept it under the weather station as a dolly.



The display has a lot of information, the display is easy to see, and most significantly the temperature is accurate as I used several different thermometers and the old weather station to cross-check the results.



The weather station is 4 1/8" tall, 5.5" wide, 2.25" front to back. The base is heavy, so the weather station is well balanced.



The setting of all functions was very easy. Each function has a dedicated button on the back. I thought the set up was easier than Oregon Scientific.



The outdoor unit runs on two AA batteries (which are not included). The location of the outdoor unit is critical to the accuracy.



FINDING A GOOD LOCATION:

~~~~~~~~~~~~~~~~~~~~~~~~

(1) The outdoor unit should be in the shade

(2) The outdoor unit should be somewhat protected from the rain

(3) Should be placed on the surface that does not get warm (for example glass or metal are bad choices, wood is a good choice)



I have been placing my weather station sensors under the deck. This is close enough to the main unit to provide strong signal and meets all of the recommendations listed above. I would estimate the distance between the two units to be 20 feet. The signal has to go through one wall.



I received Ambient weather station with the request for testing and review, as well as the request to provide feedback on the manual. I thought the manual was very good overall, very detailed. I provided some minor feedback on clarifying some diagrams and the seller makes the latest version of the manual available on line.

Product review: Clinique Even Better Clinical Dark Spot Corrector

If you are looking for a product to remove dark spot (sun spots) this product does not help. It is pleasant in texture and odor free. It is absorbed well and does not leave the skin shiny as some other preparations. The skin is left softer after the application. However, it has no effect on dark spots. After using the serum for several months I saw a dermatologist and asked her if there is any chance that this serum will work. She said no. She said freezing the skin where the spots are however is very effective. I went ahead and did it. Several weeks later my spots were totally gone, there is not even a faint mark where they were. It cost me $25 per spot (insurance does not cover it since it is cosmetic). For a week it looked like I had a couple of pimples until the skin totally healed. If any spots appear again I would do the freezing again. I can't tell where the old spots used to be.

Product review: 5ive® Dual Quick Charge 2.0 USB 36W 2 Ports Car Charger Adapter - in use with Nexus 6p

My review is for 5ive car charger in use with Type C to USB charging cable and Nexus 6p smartphone. 5ive charger forms a nice tight fit with car charger, it does not gets dislodged on bumpy roads.



Nexus 6p uses rapid charging when the battery is low. I used Nexus 6p with the battery level of 18% to do the tests of both ports. The phone showed that it was using rapid charging and drawing 2620 mA on one port and 2630 mA on another port. In the span of 5 minutes the phone got charged from 18% to 26%.



During a 30 minutes drive while Nexus 6p was used for navigation the battery level went up by 23% percent (from 28% to 51%). A dash cam was plugged into the second port of the charger. Excellent results!



I received this charger from 5ive for testing and review. Bottom line: excellent performance on both ports.

About the cable I am using:



I am using one of those type-C cables that are not USB 3.1 compliant. What is non-compliant cable? Benson Leung has a series of excellent reviews of Type C cables. Benson works for Google's Pixel group and has pointed out that many type-C cables violate the USB 3.1 specification that states that the termination resistor that advertises the maximum available current has been set incorrectly at 10K which advertises 3A of current, the correct value should be 22K which advertises 1.5A of current. These cables may not safe to use with all devices (such as the Chromebook Pixel and the Apple Macbook that draw more current than a phone). However with a quality charger that is rated for higher current like 5ive car charger and Nexus 6p (which does not draw more than 3A of current) these non-compliant cables will charge faster than a USB 3.1 compliant cable. I don't want to say that it's safe for all combinations of devices, but I have been using them with quality chargers with Nexus 6p on regular basis because both the charger and the phone are self-limiting.

Product review: Z-Edge Car DVR Dash Cam

Through the years we owned a few dash cams which gives me a chance to compare Zedge with other car dvrs. Zedge video quality is pretty decent, the colors seem to be a little washed out, but the clarity is good during the day and during the night. The suction cup worked well even on very cold days (it never let go and fell off). The user interface however was not as intuitive as other dash cams. It has a menu driven interface which I like, but the navigation though the menus were not as intuitive or easy to remember.



' This camera comes with a 32G Class 10 micro sd card, and will work with 64g gig card.



' I had no technical issues of any kind. All files were readable. The camera writes out video frequently, by default it saves a file every 1 minute. The size of each segment in my video was about 125.9MB. Writing small files improves overall reliability. It is much better than writing one large file at the end of the trip.



' The dash cam uses stands micro USB cables, the package includes a charging cable and a cable with car port charger.



' Audio is recorded clearly, the default setting is to record with the microphone turned on. It can be turned off with one button push on the side.



' Motion activation mode/parking mode is very sensitive. I hear the camera turning on and off without any particular reason. I am not sure what is activating it. As a result there is a lot of uninteresting files saved in 'event' mode. On the positive side it records even with the car not running.



Overall, I thought this dash cam falls in the middle of the pack. The video is reasonable although not the best, user interface is menu driven and logical but navigation through menus is not as simple as other dash cams.



I received this camera for testing and review. Getting a free unit does not effect what I say. The review is based purely how the dash cam worked in my experience based on my experience with a variety of different car dash cams. So far after two weeks of use the dash cam had no issues. I will post an update if it dies prematurely as I saw some people reported problems after more extended use than the 2 weeks I had with it so far.

Product review: SENTRY Call Blocker Blocking, Black list and White list

I have been using CPR call blocker for almost exactly a year. Sentry call blocker is easier to use and has features that do not exist CPR. In this review I will compare the features of these two call blockers and explain why I like Sentry better.



MODES AND CALLER ID

~~~~~~~~~~~~~~~~~~~~~~~

Sentry blocker can operate in two modes. In in-line mode the blocker is connected to the line and the phone is plugged into the blocker. In parallel mode both the blocker and the phone plug into the wall with a splitter. I could not use in-line mode because my phone no longer displayed the caller id. In parallel mode my phone displays the caller id. In both modes the blocker itself only displays the numbers, it cannot display the caller id.



How does this compare with CPR? When I used in-line mode with CPR blocker I also lost the caller id info. I have been using CPR blocker in parallel mode. However, to block calls with CPR I also had to have a spare phone attached in line with the blocker. I needed to use the phone to enter commands on the key pad, for example to block the last number called I needed to enter #*2#. Sentry blocker makes blocking easier - all I have to do is locate the number in the call log and press "reject" button for 3 seconds.



WHITE LIST

~~~~~~~~~~~

The documentation suggests that before you start using the Sentry blocker you create a white list. This is a list of phone numbers for your friends and family that will never be blocked. This list can be created manually by entering each number in the blocker (this is a fairly tedious process as Sentry blocker does not have a keypad and you need to hit a sequence of up/down and reject buttons for each number in every phone number you want to enter). Alternatively you can have this person call your phone, and then find his/her number in the call log and press "accept" button for 3 seconds. There is a third way to add a person to the white list, this is done by the caller when they press '0' on their end (more about this feature under "CHALLENGING THE CALLER").



CPR does not have a concept of a white list.



BLACK LIST

~~~~~~~~~~~

There is no way to manually enter the numbers into the black list. Since I have been using CPR for a year I have list of particular annoying marketeers who has called my number many many many times. Since I know they will continue to call I would have taken the time to enter their numbers in the block list but this is not possible and I will have to block them again when they call.



CPR does allow me to manually populate the block list.

Sentry does have a way to show how many times a particular number called.



DELETING NUMBERS FROM BLACK AND WHITE LIST

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Deleting numbers from the lists is easy. All you have to do is press either Black list or White list button, scroll to the number you want to delete, and press DELETE key twice quickly.



CPR works in a similar way.



CHALLENGING THE CALLER

~~~~~~~~~~~~~~~~~~~~~~~

This is my favorite feature of the blocker. In this mode the callers who not listed in either the white or the black list are challenged (see my video to hear what the challenge says). The caller has an option to press 0 which adds them to the white list and the phone rings. This feature totally takes care of robo calls, the phone does not ring. I would have preferred that the person could not add him or herself to the white list, I would have just liked the call to go through. I would have like to be the only one that can add names to the white list. The way it works now, I would need to scan the white list periodically and make sure some telemarketing caller did not add themselves to my white list.



Update: today a human telemarketer hit zero and added himself to my white list. To move him to the black list I found this new number in the white list and held "reject" button for three seconds. The number got removed from the white list and added to the black list.



People on the white list do not get a challenge. People on the black list do not get a challenge.



You can select if the voice that answers is male or female. The choice is shown in the top right corner as A (female voice) or B (male voice).



CPR does not have the challenge feature. CPR has only one list, the black list. Either the caller is cut off or the phone rings.



MODES

~~~~~

The phone can operate in "BLOCK NO CID" mode. The block mode automatically blocks callers that do not have a caller id. To add this option press and hold "reject" button. To remove this option press and hold "reject" button until "BLCK NO CID" disappears.



BASIC mode will let though unlisted numbers, while still blocking black listed numbers. Unlisted numbers could be something like automated doctor appointment reminders.



SETTING TIME

~~~~~~~~~~~~

Sentry automatically sets the current time when the blocker is connected to the phone line.



WHAT DOES THE CALLER HEAR

~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I had a friend call me and we experimented with blocking numbers as well as numbers on the white list. Blocked callers hear nothing, they are just disconnected. The callers on the white list get connected normally. The callers who are not on either one of these lists get a challenged and are asked to press zero if they are not marketing solicitations.



HOW MANY NUMBERS CAN BE BLOCKED / WHITE LISTED

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The total number of the two lists is 1500 numbers. The system divides this capacity between two lists automatically as needed.



WHAT CAN CPR DO THAT SENTRY DOES NOT

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I switched to Sentry after one year of using CPR. However it had a couple of features that I will miss. What can CPR do that Sentry does not?

- Using CPR I could pre-populate the black list

- CPR shows me the count of how many times a specific blocked number called. I get a satisfaction seeing a high count number of blocked calls and if Sentry's black list could be pre-populated I would have known which numbers to enter in the black list.



FINAL THOUGHTS

~~~~~~~~~~~~~~~

Like many people I hate marketing calls. There is a great mental benefit to being able to do something about these annoying calls. Now when I get a marking call I am not annoyed, I think "Gotcha!" and block it.



This call blocking device is provided by Sentry for testing and review.
