Telephone Zoom Lens for Smart Phones

This new 58mm lens for iPhone, pixel, and Samsung galaxy camera phones provide 4x optical zoom from moment. Camera phones have become very good for what they do. The biggest problem I see is the lack of decent zoom options. Even this 4x optical zoom is limited but it provides a decent tradeoff of a quality zoom lens in a small package. You just don’t get the great zoom capabilities of full cameras like the 65x optical zoom I have on my Canon PowerShot SX60 HS Digital Camera.

You need the proper phone case to mount the lens to your phone (like this case for an iPhone X.

Magnet-driven Connecting Fittings

Invis Mx2 is an interesting product (magnet-driven connecting fittings) that allow you to screw items together using magnetic forces. To use it you just use a typical drill with a connector that uses magnetic forces to turn a screw inside what you are trying to connect.

A TV That Doesn’t Spy on You?

Most (all?) “smart”/spy TVs spy on you many different ways. Some even record what you say and save that information and send it over the internet. So often these days companies say we don’t do x or y only to later say that oh well we do… And even if they say you can opt out of being spied on if the device has the capability of spying on you relying on them to actually honor request not to be spied upon seems unwise.

It seems much safer to just have monitors that display the content you requested be displayed and don’t have spying capabilities built in.

What large screen TV monitors today are free from spying capabilities imagined by George Orwell in his book, 1984?

Karma Hotspot – $50/m Unlimited Data @5 Mps in the USA

This seems like a very nice option for people with bandwidth needs that don’t fit in the tiny caps most cell phone providers put on plans. For $50/month you get unlimited data @5 Mps in the USA. You can get small increases to the speed by buying data in bite sized chunks (1Gb for $14 or $99 for 10GB, which doesn’t expire).

The bite sized chunks mainly make sense if you don’t have high data needs for the hotspot – but want it occasionally (and perhaps as backup for your primary connection). The $50/month offer is limited to 3 devices connecting at a time, compared to 8 for the other option.

The device itself costs $149. The device has up to 8 hours of battery life and over 220 hours of standby time.

Currently the devices use Sprint’s Nationwide 4G LTE network, with fallback to 3G CDMA. It seems like a nice option for travelers to me.

Portable Mini-Projector: P700 Pico DLP Projector from Aaxa

image of the P700 Pico DLP mini-projector

The P700 Pico DLP Projector from Aaxa provides high quality projection from a tiny box.

The mini-projector is just 6.9″ wide by 3.9″ deep by 1.6″ tall while weighing under 2 pounds and it provides 650 Lumens with 70+ Minute Li-Ion Battery Life, 15000 Hour LED, 1280×800 (WXGA) HD Resolution, 2000:1 Contrast Ratio, HDMI, mini-VGA, Composite A/V, USB, microSD, 2x 1W Speakers, DLP Technology and a 1 Year Warranty.

The main market is likely to provide a very portable way to give quick presentations.

I wonder if it will be of interest to digital nomads. They could use this to project video onto a wall instead of watching it on their laptop. I might consider something like this when I go back on the road. If anyone has used a device like this that way, please share your thoughts below.

HomeWorx HDTV Digital Converter (Receiver) with Media Player

I have an ancient HDTV. It is a projection “65 inch TV which is perfectly fine with me (other than it needing to have the bulbs replaced). But it doesn’t have a receiver in the TV (it is only HDTV ready – no receiver inside the box.

Not having a receiver is actually a benefit in my opinion you are not stuck with the “smart TV” spying trackware, listening to you in the room via the smart TV speaker etc.. My unit is so old it was done separately because the receiver technology wasn’t settled yet.

After I returned from 4 years overseas the receiver was missing. So I picked up a new HomeWorx HDTV Digital Converter Box with Media Player and Recording PVR Function (HW180STB) for $30.

The recording PVR option confused me because I couldn’t find the capacity anywhere. After reading a bit I learned that you just use usb sticks to store data. This lets you recored programs over the air using your HDTV antenna and this receiver.

Many people get this when they drop cable TV. I am a bit confused since many of those people have smart TVs (meaning the TV has an HDTV receiver and you can hook up your HDTV antenna to it directly). Some people say this receiver is much better so that you can get stations that isn’t received by the expensive smart TV. You also get the HDTV recording without paying a monthly fee.

It was super simple to setup. I screwed my antenna into this box and this box into my TV (both coaxial cables – the HomeWorx HW180STB also lets you use standard video cables). By far the hardest part was finding AAA batteries. I eventually found them in a small flashlight and then it was just a matter of pushing the down arrow twice and enter: then it recorded all the signals it received).

It captured 47 stations (though maybe 20 of those are pretty fake – either nothing at all or shopping channels and other stuff I have no interest in). It gets all the major stations well (except PBS seems a bit flaky)l and all I have is the antenna sitting in my basement pointing out 1 window (I din’t try adjusting it at all).

Before I left I also had only over the air TV. Then I had the antenna setup in my attic and used the cable TV coaxial cable to hook to my TV. Now I am getting my internet via the cable company so I am not sure what would happen if I try to hook up my antenna to the coaxial cabling that is now carrying my internet feed. Maybe it would work? The antenna was unhooked when I returned (I am not sure it that was done in my absence or I did it for some reason before I left).

I haven’t tried doing anything fancy yet (not even recording) but it is nice to have access to over the air TV (mainly just for sports), I hadn’t bothered getting it hooked up for 2 months. All I used was Netflix and got a HDTV cable to view the playback on the 65″ screen.

My TV is a Toshiba built in 2005 and doesn’t have integrated lamp units you just slide out and replace, sadly. This is what you must deal with to replace the lamp. What were they thinking? I guess this can partially be excused by being a very early HDTV product. But still, not providing a decent replacement option for the lamps is pretty lame. I am trying to hire someone to do it for me, so far unsuccessfully, but I have someone that thinks they can do it.

Multiple Screens for Your Laptop

The Slidenjoy laptop screens seem like a cool idea for mobile laptop users.

The main thing I miss on my laptop versus my desktop is screen real estate (I had 3 large screen for my desktop but just one 15″ MacbookPro screen.

The device attaches to your laptop and with 1 or 2 extra screens that can be displayed in various useful formats (extra screen while you work and also sharing screen views while presenting or working with others.

One USB connection is all it requires. Single Slidenjoy screens start at just €199 and duel additional screens start at €299.

Boosting Wifi Signal Strength While You Travel or While at Home

One of the frustrating things while traveling is getting a weak wifi signal in your hotel room. A good tool in that case is they BearExtender Turbo High Speed 802.11ac USB Wi-Fi Adapter for Mac OS X [BearExtender dropped support for Macs, link removed] (Windows version). Even though the mac version description says it is not compatible with Yosemite, the comments indicate an update was made January 2015 to make it work with Yosemite.

The BearExtender also works to provide better wifi signals around your house. Some models are designed to connect with your router (Netgear range extender, for example) and are not as suited to travel use as the others are). BearExtender can be used for travel or home.

Apple Watch

The Apple Watch is likely the most popular gadget of the year. People are still figuring out what benefits excite them about the watch. It seems to me the potential is huge but this initial effort is not quite amazing.

[Apple broke the link, so it is no longer available 🙁 jeez even companies with spending hundreds of millions on marketing don’t have people in charge that understand that web links must live.]

I embedded Apple’s promotional video for the watch which is obviously a sales piece but they do a very good job of showing what the watch offers.

There are many good reviews of the watch: The Apple Watch (Daring Fireball)Apple Watch Review: The Smartwatch Finally Makes Sense (WSJ)A Week on the Wrist: The Apple Watch Review (Recode)Apple Watch Review (Verge

My opinion is it is very expensive for what you get. But I can see the potential for some very wonderful things down the road. The health kit options I think will be a killer feature (maybe not right away but within a couple years).

Another feature that will be quite valuable are paying with a swipe from the watch (which seems to be less than perfect so far), but it will be very nice. Apple Pay is a very smart system given the relative ease at which consumers credit card details continue be stolen using conventional means (Apple Pay doesn’t turn over you credit card number so hackers can’t get it from poor IT systems at retailers).

The quick interactions with friends I think will be a big feature, again it may take several interactions to get this to be wonderful. The “tap” notifications seems to physically be done very well. Figuring out the right settings to properly filter what should generate that touch seems to take a bit of work (and not surprisingly apps are defaulting to too much bothering the user).

Being able to just speak to leave yourself notes is a nice feature, though my guess is one that isn’t used as much as people would think it would be.

Personally I see more potential for the watch that I see actually delivered thus far. I am more positive about the long term success of the watch today than I was when it was first announced.

I stopped wearing a watch years ago. And I don’t have any plans to start again anytime soon. But if I do, the Apple Watch is a likely candidate. It sure isn’t cheap but hopefully I can just use a bit of profit from Apple stock when the time comes to pay for one.

Save on Phone Charges When Traveling – Sim Card Savings

Roaming charges on cell phones are ludicrously expensive. When I travel I normally just get a local sim card but that does have hassles (you don’t have your normal cell phone number attached to your phone).

A new service provides much better roaming rates by directing your roaming traffic to their network instead of your cell phone carrier. The cool gadget that allows this is a sticker applied to your sim card.

You phone must be unlocked for this to work. It works with iOs (iPhone and iPad), Android and other systems and all sim types (micro, nano and mini).

There is an option to get a local number to let people easily call you locally.

When applied to your home SIM card, the KnowRoaming sticker can detect when you are at home or abroad. When abroad, the KnowRoaming Sticker takes over and switches you onto the KnowRoaming network, enabling you to connect to our local partner networks worldwide. After returning home, the KnowRoaming sticker switches you back to your home mobile network and remains dormant.

They take your balance after 15 months of no activity which is unnecessarily hostile to customers. But for the right people it might be worth looking into if this option would benefit you.
