Dark Welder 2: My DIY battery tab spot welder

Dark Welder 2: My battery tab spot welder!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!

How to get more speed from your USB drives

USB 3 Speed ExplainedJust 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!

5G loses steam, but what’s next?

5G Fizzles Out...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!

Are injectable tracking devices even possible?

Injectable Tracking: Looney or Likely?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!

No more WiFi, Part 4: Wire and test your house network

No more WiFi: Connect and test!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!

No more WiFi, Part 3: All about existing house wiring

No more WiFi: All about existing house wiringWhat 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 this video, I describe the different types of patch panels you may find in your home, how they work, and how you will use them (or not).

It’s worth noting that if you only have twisted-pair phone cabling (often called PTT-298), you CAN use that wiring for 100 Mbps Ethernet – but not for Gigabit+ speeds.

Fortunately, most homes these days have Cat 5e or higher cabling, so that part shouldn’t be a problem…

Can Shungite protect you from EMFs?

Does Shungite absorb 5G?Shungite is a stone that many people use to protect themselves from EMFs such as WiFi, 5G, and so on. But does it really work?

Well, it turns out that most of the information available on the internet appears to be dead wrong!

I do a few simple tests in this video to show that no, shungite does not appear to absorb EMFs – it reflects or partially blocks them only when it’s directly between the antenna and your body.

Well, okay, but there are still tons of people who swear by it! What’s going on here?

Should you keep using your shungite?

Is 2.5 Gigabit Ethernet better than WiFi 6E?

WiFi 6E vs 2.5 Gigabit EthernetFirst of all, it’s finally happened: 2.5 Gbps Ethernet is HERE!

It’s already rolling out, and consumer-grade 2.5 gig switches will arrive shortly.

The other big news is the unveiling of WiFi 6E.

A new flavor of WiFi 6, the 6E variant adds the 6GHz radio band and speeds of up to 11Gbps… Or so they say.

So, the question is: stick with wired, or go WiFi 6E wireless? Which is faster?
