The death of the iPod dock

Gone are the days you need to dock something to get music from it! Bluetooth  docks are the way to go.

I was helping a neighbor get surround sound from his iPhone a few weeks ago, I tried anyway. Dug out my trusty KEF iPod Dock that I purchased on a really good deal a few years ago. If you don't know KEF, they are an audiophile speaker company from the UK. The entire case of the speakers are metal! Anyway, let me get back to my story, took it over, plugged in all the wires (old clunky system, has more wires than the unit itself!). Docked an iPhone 4S (note: not even an iPhone 5). BAM! The apple'a version on BSOD, blue screen of death, "This accessory is not compatible with this Apple product". Nothing really to do beyond this...

This got me thinking, we all probably have an iPod Dock of some sort, like a clock radio, speaker system, cable with the receiver system etc. but Apple has made some suttle changes to the 30 pin connector in recent versions of their products and of course the new lightning connector! I quickly see every accessory in my house starting to become extinct. Well, as long as I keep my old apple products in working condition.

Sooooo, if you are considering to get an iPod Dock speaker system, don't!!!! Just stick to Bluetooth. The new wave of speaker systems like the Bose Soundlink II, Jawbone Jambox, Logitech UE boom box etc. are completely wireless. This means, no more docks and the phone or tablet or even laptop does not have to be next to the unit. You can"stream" it via Bluetooth. Using bluetooth also makes it easier to connect non-apple products (in the past you couldn't "dock" these), like android phones or tablets. You lucky Samsung owners can benefit from having music surround :-). Worh clarifying on thing, you can stream music from a tablet or phone or even a laptop that is BT ready.

A few things to consider whe choosing the type of portable speakers:

1. Size

2. Sound quality (smaller they are the less bass in the sound) - this is just a rule of thumb, some out there are great and small!

3. Battery life. Since they are portable, you want to be able to take the anywhere and play it without having to plug it into the wall.

4. Weight (goes with the portability comment!).

5. Compatibility should be Bluetooth, these are fairly standard. There is a slight chance that the BT versions change in time (very slowly in time), but I think you are ok for the next few years, but these Bluetooth protocols won't change hence you can always stream the music via this method.

6. Apple AirPlay, this is their own protocol that allows more control on iTunes wirelessly and helps with streaming across wifi. 

The next wave of connected decides will probably be wifi based (router and direct).  But until the protocols are defined and agreed upon, I think it will be a few years before we see true adoption across manufacturers.

I suggest taking the time to read reviews and also listen to the products at a store before buying. Personally, I have the older Bose sound dock and love the sound. The future will probably be the soundlink (note the dock name changed to link :-)).

If you have a favorite model that you are happy with, leave a comment so others can benefit from your experiences!

Are mobile payments becoming commonplace?

Unlike my friend Kannan who has a new baby at home keeping him busy, I have no excuse for such a long absence from this blog post. I am just plain lazy :)

I did write a blog for the Retail Touchpoints magazine on the topic of mobile payments and how it can become reality as part of my day job, so i thought why not share it on this tech blog :)

That post went live a week or so ago online at

Are Mobile Payments Becoming Commonplace?

Check it out and add to it with your comments!

"XBOX", please make me a cup of tea...

Ok, Ok, my xbox can't make me a cup of tea (yet!). I recently came across a nifty feature of xbox+kinect PLUS voice command capability. This combo translates to a fully handsfree REMOTE!

First I wanted to apologize for being absent for almost 3 weeks now....we had a baby! Everyone is doing well and finally I am getting back to reality.

So, when I was looking at putting a TV in our bedroom for my breastfeeding wife who will probably spend 80% of her time for the next few months in the room, I had planned on putting an old laptop rigged up with wifi, HDMI and optical out for audio. Remember, we don't have cable TV, so I need the laptop to stream video (live TV with Mohu Leaf wasn't going to work at 3am!). This worked, but a huge mess with wires and remotes and having to use a mouse to run the laptop etc. I think my wife would just be better off with a kindle...

Then BAM! I remembered I had an XBOX 360 in the living room (from this comment, I think you can guess when was the last time I used the XBOX). ANYWAY, I vaguely remember reading somewhere that the xbox can stream hulu, netflix a few other online sites. I also had a XBOX live membershop card that wasn't activated :-)

I hooked everything up in the bedroom, turned out quite neat since there are minimal wires (just HDMI to the TV) and Kinect wires are hidden behind the TV anyway. Booted it up, spent the next 45 minutes logging in, getting setup with a live account, updates etc.With Kinect, you can use hand gestures, which worked just OK for me, maybe the lighting in the room wasn't enough or something, but also not truly "handsfree" since you still have to use your hands. While fiddling with the xbox software, I found a neat little feature called "VOICE COMMANDS". You just say "XBOX" and it wakes up and asks for more commands. It gives you a choice of certain letters and words to use which are highlighted on the screen. You can then say things like "Apps", "Hulu" and best part is that the commands work inside the apps as well. You can say things like, "Shows I watch", "Greys Anatomy", "Play most recent" etc....

And why is the useful? Well, if you are carrying, handling, rocking, feeding a newborn, the last thing you want to do is fiddle with a handheld remote. I think this is a great way to automate an age old problem of using remotes. Of course, some newer TVs have similar features built in, but who wants to spend $2000 on a new top end TV? If you have an XBOX 360+Kinect, just need to get the Live membership (obviously not free!) and start using your voice!

PS: Once my wife started using this in the last few weeks...her words "One of the best ideas you have had!". So, there you have it, proven and approved by a mother (and most importantly my wife!).

Love to hear what other nifty ideas you have to help new mothers, leave a comment!

Home health monitoring in the smartphone age - Not upto par......

I am a "diagnosed diabetic" for almost 10 years now and have used many blood glucose meters and a couple of blood pressure meters to keep track of my vitals to help manage my health. The first time i went to see the doctor after being diagnosed with diabetes with a colorful chart, the doctor was surprised and said I was the first of his patients to do this. That was the honeymoon phase right after being diagnosed when I was serious about controlling it. It has been an up an down battle since then. What i had to do was take the measurements on the blood glucose (here after BG) and blood pressure (here after BP) meters and then once a week would enter into an excel file and then plot it to see the high lows and the average. This was helpful in my follow up discussions with the doctor. did that the first 2-3 visits and then stopped as i kept forgetting to input them into excel. There were some meters out there that had an audio out jack that allowed you to connect to a Windows PC the meter and download the data using special software.

Being a techie, i could not believe this. Seems hard to believe we didn't have something easier. But looking back I realize this was 2003-2004 I am talking about (seems like eons ago before the smartphone era with cool apps, doesn't it?).

Back in early 2012 i found an app aptly named "BloodSugar" by healthycloud that i have been using to input my readings. This app is cool and allows you to see your history as a table and as a chart that i have been showing to my doctor during recent visits. Also found a BP app called "BPMonitor" by Taconicys that is similar with tables and charts to see historical data.

    
But the funny part is that even after so many years of smart phones being around, the big bad pharma companies have not come out with meters that either talk to a phone over Bluetooth or NFC or a meter that just attaches to the smartphone as a dock! Well one small company has. This BG meter that connects to the iPhone is called iBGStar. I can't wait to try it out. I just found out about it. There is also a "MyGlucohealth" BG meter with Bluetooth that is out there but there are concerns about the accuracy of it's readings.

Hoping that the more popular brands like AccuChek (Roche), Bayer, Freestyle (Abbott) would not have bluetooth enabled meters. Roche has a bluetooth controlled insulin delivery tool but not a meter. Go figure.

I prefer the Bluetooth enabled meters in place of the dock-able ones as the connectors in every phone seems to be different.

Please share if you are aware of meters available in the market that are up to par for automated tracking!!!

Cheers to everyone's good health and staying healthy

What? More monitors???

Baby #2 is almost here, so as you can image, I've been spending a lot of time getting prepped. It is amazing how fast you forget things. Ram and I seem to have an obsession to cut cords and monitor things remotely :-)

I will make this one short, do you need a baby monitor? Answer: Yes. Do you need one that has a camera? Answer: Yes. Why with camera? Because you can and since technology has really taken root in this nifty gadget.

I do believe they are quite pricey, but there are just too many options. I kinda tripped over one when our first son was born. It was by a brand called Levana. I forget how I found it, but glad I did. Some typical features I suggest looking for:
1. IR capable so that you can see images at night
2. Digital wireless connection (for privacy)
3. 2.4in or larger screen on the receiver
4. Easy mount for the camera incase you need to clip it to a bookshelf.
5. VOX (See below)- Levana's charm!
6. Temperature monitor

The most nifty feature is the VOX feature (at least that's what they call it). It is a feature that will only turn on the screen if the sound is sharp and loud. So, when the baby is turning around, breathing heavy, slight ruffles etc, NOTHING happens. You may think this is what you need to hear, trust me, you don't! You want the system to engage with the child screams, starts talking, falls off the bed etc! I have only found this feature in Levana products (BabyView20 and Jena). I still have the BabyView20 (had it for 3 years) and just upgraded to Jena with two camera for Baby #2. Quality is ok, had to get a few Babyview20 replaced on warranty due to usage issues, but I really like the product, particularly for this VOX feature, which is also called PEEP. And key feature to note, it is multi-voltage, we take it along wherever we are going...UK, Malaysia etc.

Anyway, I am probably rambling now, just getting ready for the sleepless nights coming up. If you have any suggestions for better monitors, please leave a comment! I am sure others would like to hear your stories!

Open Sesame....

I am a hardcore apple fan and as expected was online following the latest Apple iPhone 5s event on CNET the other day. As was rumored the iPhone 5S does include fingerprint technology called TouchID, similar to the one I wrote about in the Ding Dong article earlier. Fingerprint has been the way of identifying people from the prehistoric ages....see this article online for a history about fingerprints - http://onin.com/fp/fphistory.html or read chapter 1 of this book http://www.nij.gov/pubs-sum/225320.htm by the National Institute of Justice (kindle or other eReader versions available for free).

The objective of apple is to help speed up things - basically eliminate entering passwords the umpteen times you access your phone in a day. Just place your finger on the home button and voila - open sesame! That is convenience at its best combined with security. This maybe the beginning of the end of passwords and pass codes if other smartphone manufacturers follow suit which I strongly believe they will.

Take for example the point and shoot camera that are slowly vanishing given the quality of pictures on most smartphones getting better by the day and the convenience of taking pictures with a phone instead of carrying a second device in your pocket. Or the home phone for that matter is slowly fading away.......

Best of all is that this could be the beginning of true mobile wallets for mobile payments eliminating the need for credit cards someday.  Given Apple has talked about using the TouchID for iTunes and app store purchases, I believe this will surely be followed by combining Passbook app with TouchID for quick online purchases  and may be even offline at the retail stores. Combined with blue tooth technology in iPhone or NFC in other phones (like the Fujitsu Regza phones in Japan), placing your finger on the fingerprint sensor can approve payments to a credit card terminal at the checkout lane at the retail or grocery stores. This way next time you go out all you would need is your phone and your drivers license for ID.

Maybe the day is not far when the phone with fingerprint sensor on it is your proof of ID :)

On a historical note, Apple is not the first company to put a fingerprint sensor on a phone. Siemens (Germany) and Sagem (France) experimented with sensors on phones back in 1998 and 2000 respectively but it was Fujitsu of Japan that came out with the commercially successful clam shell (flip) phones that had fingerprint sensors on them in 2003. Fujitsu is the only phone company that has built the most models (30) with fingerprint sensors on them. The japanese already use phones extensively to make mobile payments for purchases at vending machines and at stores. Motorola (Google now) and Fujitsu both announced Android phones back in 2011 with fingerprint sensor. The Motorola Atrix model did not take off and was discontinued but Fujitsu has had some success limited to Japan.

Fujitsu F505i - with fingerprint sensor released in 2003                                                          

Now let's wait and watch if the magic of Apple can make this commonplace the world over......or will it  also end up on the heap of cool but discarded technology pile.

Cut the cord (again!)

WiFi for the home is an important feature of any household these days. But how should you set this up? There are probably a million ways to setup a home network. Here are my $0.02 on how I would go about it.

First things first, 802.11AC, this is the 5th gen WiFi protocol. I think this is needed, but 2-3 years down the road, UNLESS you are moving a LOT of data inside your home network (trust me, you are NOT doing this today!). Remember, if you chose 802.11AC, both the router and laptop/PC must support this.

Okay, now on to more "regular" WiFi. A couple of key features you should check out before getting a new router, simultaneous dual band and 802.11n. Dual band means, the router can operate on the 2.4GHz band AND the 5.0GHz band. This is critical to understand since now you can have two wireless networks in the house, running at different frequencies. 802.11 b/g runs at 2.4Ghz which is shared with your microwave oven, Bluetooth, some cordless phones, baby monitors etc. And 802.11a /n runs at 5GHz which has less interference, so it is cleaner and able to sustain the fastest speeds. When you have interference, you may not lose the connection, but it becomes significantly slower and FRUSTRATING!

If you recall my blog on cutting the cable cord for TV, I now use my internet for TV viewing. I noticed the dreaded "loading" icon on my TV when I was trying to watch TV. I started to play around my router setups and dedicated a 5GHz network for my high bandwidth systems, TV, ipad and work laptop :-). I then put all other devices on a regular 2.4GHz network, like phones, ipod touch, audio streaming, webcams etc. I've noticed significant improvement in my TV viewing experience!

Of course, true internet speeds and bandwidth is determined by your internet connection, so WiFi data speeds are probably not a bottle neck but can be if you have good internet speed. I did some testing to see how these things are related. Here is an example:

My internet speed on AT&T UVerse (fibre to the curb) is 18Mbps based on what AT&T tells me (or robs me). When I perform speed tests using my 2.4GHz network, I get 12-13Mpbs and when I use the 5GHz network, I get 17.5Mbps. This clearly indicates to me, if I have internet speeds more than 13Mbps, the WiFi network is my bottleneck! But I should quantify that for normal internet browsing etc. 12Mbps is more than enough.

How did I setup my home network? Well, I am kinda cheap (for those who know me well), I have an Apple Extreme base-station from 2008. Apple is typically ahead of the curve, so I had a dual band router (but not simultaneous). I can't run 5GHz and 2.4GHz at the same time.... Then I realized I had a WiFi router built into my AT&T modem (that can ONLY run 2.4GHz). Then it hit me!!!! I now run a 5GHz network using the Apple router and 2.4GHz using the AT&T router. And you can put them next to each other since they are running two different frequencies, there is little degradation to the signal. The EASIEST way to get this going if you have a router more than 3-4 years old, is to just get a new dual band (simultaneous router). I recommend the Apple router/base station family. I have used many brands in the past. Seems like they all have their quirks. I've been the most happy with my Apple router. It just works and you never have to re-boot it. As common practice, I also recommend re-booting any router from time to time.

For some reason, in Malaysia, seems like modems wear out faster, maybe the heat and dust, I do recommend changing/replacing the router every 2-3 years, obviously only if they are the cheap ones. It would hurt to keep changing the Apple router that often!

As an added bonus, if you get the latest Apple router, it is 802.11AC ready, which is the next generation 600Mbps speed!

Leave me a comment if you have additional questions on this topic, would be glad to help.

adios,
Kannan

The Monitor Lizard

(or Wizard)... For those of us who are still holding on to a desktop pc at home, the search for a monitor can be challenging. There are sooooo many out there now. A good large monitor will make the entire experience of working from home significantly better! Some of us also have home docking stations for laptops, this needs a good external monitor. A few things to consider when looking for a monitor: size, connections, resolution. Gamers and tech savvy readers, this is probably too generic for you, I am sure you have your own favorites on latency, color reproductions, size etc. I wrote this for the "others" who need to replace or upgrade a home PC monitor.

99.9% new monitors are already LED backlight, don't really have to "look" out for this. The power consumption is definitely an advantage when using LEDs. I find the sweetspot for a monitor when comparing size to cost, 23"-24" is the best currently. The cost to size ratio keeps getting better as time goes on. About 2 years ago, 21" was the best size to buy. 27" and 30" are the next two steps and the cost probably doubles as you move up to these sizes. The most prevalent 27" is the current Apple iMac and their cinema displays.

27" is not common in windows desktop PCs, since the price of these monitors are in the upwards of $700 right now. A decent 24" is $250, an awesome 24" is about $400.

Settled! 24" it is. (or 27" if you have the cash lying around), what about resolution? The most common spec is 1920x1080. This is pretty much the resolution of every 23-24" monitor out there. HOWEVER, there is a class of monitor using IPS screen (in-plane switching) = really sharp pictures. These monitors have a resolution of 1920x1200. Ok, so you may think 1080 to 1200 is only 120 extra lines, not a big deal. It is a big deal, you get to see more rows on an excel sheet, documents are easier to read, as you get more are at the bottom of the screen. I am a big proponent of dell Ultrasharp series of monitors (and NO I don't work for Dell). I've had the 20.1" and the 24" Ultrasharps from Dell and am really happy with them. Dell considers these their "premium" line so inherently the quality and service is better. The same higher res. applies to 27" as well. The Dell Ultrasharp 27" is probably the closest to Apple's 27" iMac. iMac obviously has the computeer itself built-in to it, Dell is just the monitor. You should consider the all-in one PCs if you want windows 8 and touch screen. I am a little more old school for that!

What connections to look for? HDMI or DVI is a must. They are the same, but have different connectors. If you have a HDMI out from your laptop or desktop, then look for one with HDMI (if you really like one with just DVI, you can get a cheap adapter from HDMI to DVI). All monitors have regular VGA, which is typically the blue cable. HDMI is black, DVI is white. See below, far left is DVI, then HDMI, then VGA. IF you have these 3, pretty much covered for most PCs and laptops.












There is one other connector to consider, displayport. This is very similar to Thunderbolt that Apple uses. If you want to use a mac or macbook with your monitor, then you need to double check the connections and compatibility. Thunderbolt connection is the best for Apple products, only available on newer Apple products (I think they are backward compatible with displayport), but in order to get thunderbolt capable monitors, you need to buy an Apple monitor = $$$. I am not the expert on Apple products, so do check some online reviews before getting a monitor for Apple products. The older mac's and mac mini's support displayport (and HDMI if I am not mistaken).

Soooooo, what do I recommend?
If you want a mainstream monitor, then 24" Ultrasharp (or anything with 1920x1200) for 99% of PC or windows based machines. Mac lovers, the 2013 Ultrasharp has Displayport built-in so this could be a great option.
If you have the money, then get the 27" Ultrasharp. If you laptop or PC is more than 2 years old, check to make sure it can handle the resolution. Sometimes, older video cards can't handle these resolutions (critical for 27").
If you are an Apple fan, then forget the wires and get the 27" iMac!
If you are wondering if you should get a touch capable monitor for windows 8? I haven't looked into this, I feel that it's probably best to get mult-touch screens in an all-in one PC.
If you are wondering what a monitor lizard is....


Till next time folks,

Keeping an eye on the nest when the bird is away

One of the things i tried out recently was to install an internet protocol network camera (aka IP netcam) in and around my home to keep an eye on things over a smartphone (iPhone 4S) when we are away or out of town. I started the search for cameras online and found a brand called FOSCAM from China to be very popular all over the web. So decided to give it a try.

I found the foscam FI8910W pan & tilt ip network camera for $80 on amazon.com and ordered it. Two days later....the package arrived. Inside the Foscam box, i found the camera, antenna, ac power adapter and a small cd disc (not good for my iMAC as it has a CD slot lengthwise on the side so the CD will just fall in). NO documentation at all as is the case with most chinese brand products. They can do everyone a great favor only if they included some instructions. So off I go to everyone's favorite google.com to search for installation instructions for Foscam F18910W. I found some written instructions at foscam.com US site as well as youtube videos by "AwkwardHamster".




Lack of instructions made the installation process a cumbersome one given I am not a networking savvy individual. yes even for a techie networking or debugging issues with WindowsPC is not an easy task. The camera did support what is called WPS (Wifi protected setup) but my ATT Uverse router does not, so after about 4-5 hours of messing around with detecting the camera on my wireless network and setting up a free DNS at "noip.com" (domain name server so that i don't have to remember the ip address of my camera full of numbers), I was able to see the video feed from my camera on my iMAC browser window. Phew!!
You can avoid the trouble of figuring this out by following the instructions at http://foscam.us/blog/foscamipcameras/set-up-guidetutorial-for-foscam-fi8908w/ or the youtube video at http://www.youtube.com/watch?v=2xKu4uZtt3M
If you have trouble even after this, please email me and I will be glad to help.

After this came the task of downloading the free app "CamViewer" in the iTunes app store and setting it up to access my camera on the iPhone. This is where the DNS server came in handy which you need to enter on the settings of the app in order to be able to view live streaming video as well as control the camera from anywhere in the world. This is really cool as you can move the camera around up and down and sideways (pan & tilt) and see the video stream live. The camera also includes IR lights around the lens to illuminate upto 15-20 feet at night time. The picture quality is not as good at night but will work.

I also found instructions by "AwkwardHamster" on youtube to setup email or sms notification of photos to me in the event of a motion alarm. So when motion is detected (there is no motion sensor in this camera instead the camera uses change in the images in the frames of the video to detect motion), the camera snaps 5-6 still photos and sends it to your phone (data charges do apply :)).

Finally I had to order a 10 foot long power cable to extend the reach of the charger in order to be able to hang the camera on the ceiling looking down (hardware is sold separately).

So after all this, do I recommend this camera. The answer is YES as it is not bad product but lacks good setup instructions.  The FI8910W is only a standard definition video camera,  so if you get their IR filtered HD version (FI9821W) then for sure you will be very happy with the results. There are also other IP net cams  from D-link (DCS2210) and Belkin and few others that have better instructions and are easy to install but cost about $50-150 more. The choice is yours. All these cameras including the foscam i am using are all meant for indoor use. If you want to monitor the surroundings of your home or office, you should purchase the outdoor camera unit (FI9805W) which has a weatherproof enclosure and has lot more IR lights for the outdoors.

Finally if you only want totally wireless (battery operated wireless network) cameras, then there is a product called "VueZone" by Netgear that has its own router and is much easier to setup (vuezone.com). The drawback is that you want to use this one to only email photos to you when motion is detected otherwise you will drain the battery sooner than the 6 month life advertised. I will try this in the future when they have better cameras as i read the camera images are not that clear.

So that is all on how to keep an eye on your nest while you are away on vacation, or use the camera as a baby monitor or maybe even as a nanny cam to keep an eye on your sitter and the kids when you go out for the night!

Cutting the cord...

I find myself evangelizing over the air TV lately! We got rid of cable TV about 18 months ago. It was a cost cutting initiative at the beginning but what really closed the deal was a post I saw on Facebook; Someone posted that they suddenly had a lot more time to do other things with their kids etc. I started with just getting Hulu to replace the recording capability. It 's just another way to get network TV (like ABC, NBC, etc) on demand. I pay the $7/month for Hulu plus which gives you HD quality and less advertising. Unfortunately if you like USA network or HBO etc, you are out of luck! Stay with the $50/month for cable TV from Uverse, FiOS or satellite.

How do you get Hulu? Well, most newer TVs have the app built-in, else you can get a DVD player (less than $60) that can do this or a Roku box ($60-$90). If you are getting a new TV, I strongly recommend a TV with wifi built-in and has the ability to get the apps (it helps to keep a cleaner TV cabinet = less wires!). Now with apps on the TV, we can also use Amazon prime and Netflix. So we are covered. There is only so much TV you can watch anyway.

Since we live in Texas, tornadoes and bad weather is something to watch out for. You probably need to get some sort of "live" TV to make sure you can be prepared. Did some research on HD over the air antenna's and found this company called Mohu (www.gomohu.com). Read a lot of reviews and decided to try it out. They work really well! It's just a letter sized paper (laminated) that mounts at the back of the TV. I have to be honest, some glitches here and there on some channels but for the most part, all the local channels works well. NBC, ABC, CBS. And since it is digital TV, there is a weather channel as part of one of the local channels. You can always mount something in the attic and re-wire the house, but I opted for the lazyman's route.

One parting note, I suggest negotiating to get the best deal on a good (more than 10 Mbps) high speed internet connection. You will need it since all the TV shows are through the internet connection now (Hulu, Netflix etc.).

I do have some pointers on setting up the wifi network, wifi routers that's worked well for me. That'l be a topic for another day.

Sorry for the international folks, this blog is probably most useful for the USA. Will accommodate the WW guests soon. If you want to get email updates, sign up at the bottom of the page so that you get the latest from Ram and Kannan in your INBOX!.

Ding Dong!

Welcome to the home of Easytakeontech!

Our lives typically revolve around three places - at home, on the road and in the office. 

So sitting at home, i was thinking what electronic products would I install at the entry to make our lives less stressful. The most popular would be the electronic bell with built in intercom. This allows a visitor to notify you of their presence and you could talk to them without opening the door to find out the purpose of the visit. This way you don't have to talk to any unwanted solicitors who come knocking at our doors everyday. My wife would feel even more secure, if she could actually see who it is before opening the door. The traditional peep hole serves this purpose, but technology makes it better with a compact wide angle camera replacing the peep-hole and a display on the inside of the door or a wireless connection to your TV or phone will show you who it is without you having to move a muscle. There are a few products like these available in the market today. Let me know if you are interested.

But the one product that gets me excited is the electronic door lock. The biggest problem I have is being locked out or fumbling for the keys at the door. If i did not have to carry a key or bunch of keys and just unlock the door by entering a pin, or placing my finger on the lock or even better waving my phone (with near field technology or NFC) would be cool. More about NFC in another article.
Biometrics, the use of one's unique biological traits like fingerprint, face or eye (iris/retina) as a form of authentication is used to secure access to nuclear plants, defense establishments and other high security facilities. I worked with a company back in 2001 that built fingerprint door locks for the home. It's a standard front door handle with a fingerprint sensor and associated electronics embedded in it. Runs on two AA batteries for about 6 months of average use. The best part of this lock is no keys to carry or pins to remember. As long as every enrolled user is present in person, they can unlock the door by just placing their index finger on the sensor. Imagine the kids coming home and walking in with the ease of placing their finger on the door. This is convenience and security all in one. Not bullet proof but it does make it very convenient.

If you are interested in getting one, Adel fingerprint locks are sold at Amazon


I will conclude this post with a disclaimer that as with all forms of technology and for that matter non-technology products, there is always a risk of failure and so you need to consider these with an open mind of risk you are willing to take versus the convenience you want in life.

Cheers and stay tuned for lots more.....

Welcome, Vanakkam, Namaste, Selamat Datang, Howdy!

A buddy of mine (Ram) and I were talking last week on a topic that has been on our minds for a long time. We have all these ideas, or useful tips on technology that we share with family and friends frequently, but how can we reach a larger audience for the greater good :-) These are obviously our own opinions and everyone is entitled to their own, but we thought we can start a blog or website and "share" our tips for technology. We are techies ourselves and work in the electronics industry, that means nothing for these tips, but I think engineering minds think about problems or solutions differently. We will be talking, posting, reviewing technology you can take with you from the home > car > office > airport > flights!

Stay tuned,
