We’ve heard a lot in recent years about the dangers of an EMP (electromagnetic pulse).
The power grid will go down, communications will be toasted, and some have even claimed that 90% of the population will be wiped out!
This begs the questions: How bad is it, really?
What actually happens during an EMP?
Is the threat real, or have we all been watching too many Hollywood movies?
It’s everywhere these days: 2FA (two-factor authentication).
More and more, you must use something more than just a password to secure your online accounts.
Some sites, like PayPal, are apparently requiring 2FA for everyone.
So, what types of 2FA are there? Do you have to use a smartphone? Is there an alternative to SMS-based 2FA? And most importantly, is it that much safer?
Finally, I reveal the other reason why everyone is pushing 2FA so much – and it doesn’t have anything to do with your security or privacy!
Due to popular demand, I finally imported all my vids to LBRY.tv.
You can find me here:

I will still be publishing new vids on YouTube, but for any “controversial” topics, LBRY may be the only place you’ll be able to see that content going forward…
Of course, you’ll always be able to watch any vid from this here web site!
Power banks, portable USB chargers, battery banks… Whatever you want to call them, they’re very handy for charging your gizmos on the go.
The only trouble is that almost all of them take AGES to recharge themselves.
Even though many models support Quick Charging of your gizmos, the power bank itself usually only gently sips juice from the wall outlet as it leisurely refills its internal lithium-ion cells.
Typically, you may have to wait upwards of 14 HOURS for a full recharge! That’s not very convenient.
Enter the RAVPower 26800mAh USB C Power Bank – with 30W quick-charging INPUT for a full recharge time of only 4 hours!
But the fun doesn’t stop there…
After the failure of my $16 battery tab spot welder, I saw Kevin Dark’s DIY version.
But it wasn’t exactly what I needed, so I decided to build a modified version.
The Modified Dark Welder, or Dark Welder 2.0, has a foot switch that triggers a precise welding current pulse that is always the same length of time – no matter how long you hold down the button.
And in my new version, the button is now a foot pedal to keep your hands free.
The best part is: IT WORKS!
The latest news about 5G isn’t exactly flattering.
After dealing with nothing but hyped-up descriptions of the Technological Wonderland that awaited us, now even mainstream techie news seems to be all about bashing 5G instead of promoting it.
What happened??
In short, reality sunk in.
I suspect we’ll see some rather substantial evolutionary changes in wireless service instead of the revolutionary changes we’ve been promised – and that’s not necessarily a bad thing!
I’ve been looking for a cheap battery tab spot welder for 18650 lithium-ion cells for awhile now.
The usual ones just aren’t worth the cost. For example, for half the cost of a welder, I could buy at least 2 brand new power tool battery packs.
Enter the $16.99 Portable Mini Spot Welder!
At that price, it was worth a shot…
We often hear lately about nefarious plans involving injectable tracking devices… But is such a thing even possible?
Given the current state of technology, would such a thing even work?
Better yet, HOW would it work?
After all, it’s a long way from contactless payment cards to tracking chips floating inside inside millions of people who are constantly on the move.
The answers to these questions surprised me – and they may surprise you, too!
Wireless charging is all the rage these days.
Unfortunately, it’s not quite up to par.
It turns out that most chargers are actually wasting tons of electricity – and they’re not exactly easy to use, either.
Join for me for a look at yet another wireless technology that leaves a lot to be desired…
This video is a continuation of Part 3!!
What happens if you want to set up a home network, but you already have existing Ethernet cabling and wall jacks?
While it may seem simple, it turns out that you need to do some investigation first.
In Part 1 of this video, I described the different types of patch panels you may find in your home, how they work, and how you will use them (or not).
In this video, I’ll show exactly how to connect everything!
