These days, everyone just uses their smartphone for GPS navigation.
GPS is also present in most cars.
In the olden days, we had dedicated GPS gizmos for navigating. You can still grab a GPS-only device these days – and for fewer bucks than you might think.
But is it worth it to have a dedicated GPS?
It turns that yes, it is… For quite a few reasons, actually, not the least of which is simple privacy.
When the time comes to upgrade your puter, you may end up with a leftover hard drive or SSD.
Obviously, you’re going to need to recycle the drive…
But what about the data on it?
There are a million ways out there to erase a drive before sending it to the great bit bucket in the sky…
But which one is best?
We hear a lot these days about China and the E-vils of their techie toys.
Obviously, there is also a lot of political nonsense going on here given China’s economic rise on the world stage. But how bad are Chinese toys – really?
I mean, everything is Made in China anyway, right?
Join Cletus and I for a fascinating look behind the tech curtain! Iron curtain? Red curtain? Some kind of curtain!
Many people have asked me how to use ethernet instead of WiFi with their tablet or smartphone.
While the idea is simple enough, getting ethernet to actually work with your gizmo can be anything but easy…
Some devices simply won’t work with certain USB-Ethernet dongles, and other devices won’t work at all with any dongle – period.
So, the short answer is: it’s complicated!

Ever since I made my Stylish Smartphone Faraday Box videos, countless people have told me to just use a microwave oven, or just use an empty potato chip bag.
Well, no… And yes! It depends.
The truth is that Faraday cages don’t block signals – they attenuate (or weaken) them.
That means that depending on the situation – the phone itself, the signal strength, the microwave oven itself, and so on – it may or may not work.

“Ladies and gentlemen, welcome aboard CletusAir flight 353 with non-stop service to Mos Eisley.”
“Please return your seatbacks and tray tables to their upright position, fasten your seatbelts, turn off and stow all portable electronic devices, or put them in airplane mode for the duration of the flight.”
Eh… Why airplane mode?
Most of us think it’s to prevent interference with the airplane’s electronics.
It turns out that’s not quite correct…

It’s time for something completely different!
I’ve wondered for awhile why oscillating multi-tools don’t cut skin.
I know there are many explanations out there, but it appears that many people were in the same boat: We kind of understand, but not really…
Well, that simply won’t do!
Behold the two reasons why these power tools don’t (easily) cut you!
Way back in 1995, I was a freshman at university. I had this new thing called “The Internet” at my fingertips.
It was cool, but I wanted to know how it worked. I asked someone, and they wouldn’t answer the question – mostly because they couldn’t answer!
Today, everyone knows and uses the internet, but people keep asking me questions about the basic concepts that make it go.
So, I figured it was about time to give a basic intro to how the internet actually works, including a simplified discussion of networks, IP addresses, ports, protocols, DNS, bandwidth, latency, and more!
I recently finished reading the book Surveillance Valley: The Secret Military History of the Internet.
Now, I’ve known for awhile that the world of high-tech – and especially the internet – doesn’t quite work the way everyone thinks it does.
We worship tech billionaires as if they’re the Second Coming, praising them for their ingenuity and standing in awe of their sheer genius.
The reality, on the other hand, is a bit more mundane.
Pretty much all the big players in the internet/tech world got where they are with a little help. And by “a little help”, I mean A LOT…
Your average home WiFi router or access point often has a setting so that you can reduce its transmit power level.
This is pretty handy to know given what I talked about in my earlier video, Are WiFi, Bluetooth, 4G, and 5G bad for you?
The typical range for 2.4GHz WiFi is 150ft (46m) indoors, and 300ft (92m) outdoors. For 5GHz Wifi, it’s more like 50ft (15m) and 100ft (30m). The lower you set the power, the shorter the range – but the less you are blasted by the WiFi signal!
There’s no reason to leave the transmit power at maximum if you don’t need the range… As an added bonus, lower range means increased security since it’s less likely someone else will “see” your WiFi network.
