Most lighting these days uses LEDs. They’re super-low power, provide good light, and last a long time.
But you probably still have some fluorescent lights left.
If you’re like most people, you haven’t quite gotten around to replacing them with LED tubes. You really should replace them though since LED tubes use much less power than fluorescent ones.
The trouble is, it’s complicated. There many types of fluorescent fixtures and rewiring is often required.
So, how do you make it as easy as possible?
Given the state of the world, you could be forgiven for planning ahead with things like back-up power and a method of preserving food.
Deep freezers – or chest freezers – are great for storing large amounts of food for a long time.
But how much juice do they really use?
If you’re running on the back-up power of a generator, for example, will the deep freezer suck too much electricity?
It turns out the answer will surprise you!
2020 has been a crap year all around, but the battle of the fastest processor has been pretty interesting.
AMD is rising, Intel seems to be falling, and Apple recently switched to their own home-grown ARM-based chips.
So, which is best? Which CPU is the fastest?
As usual, it’s complicated…
Going forward, let’s just say that 2021 will be an even more interesting year as the battle heats up and consumers get more speed, lower power consumption, and even lower prices!
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!
Everyone has annoying technical problems.
It’s just part of Computerized Everything these days.
Usually, we tend to become aggravated when these problems occur… But what if we didn’t have to?
What if you could solve your own techie issues with a minimum amount of frustration – and in record time?
If that sounds like a plan, join me for the best techie tip yet!
These days, 2FA (Two-Factor Authentication) is all the rage.
Instead of securing your account with only a password, you have to enter a password and a secret code… But where to get this code?
The simple way is via an SMS to your phone, which means you also must provide your cell phone number to various sites.
Smartphones also have authentication apps, but the problem is that you must still have your smartphone on and connected to the cell network in order to log in to a simple web site!
That’s not very convenient…
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!
Just how fast is USB 3?
There seems to be a bit of confusion out there about how fast USB 3.x devices can actually go – as well as how to actually obtain those blistering-fast transfer rates.
That’s not surprising since what should be a pretty simple topic is actually quite convoluted…
You may recall my earlier video, Slow copy speeds with USB 3? No problem! 🎞
I was recently informed by one viewer that 400 MB/s is completely impossible for USB 3, so I guess it’s time for a review!
