There are many ways to trace a bunch of wires from point A to point B. Most of them kinda suck for one reason or another.
Enter the Voltcraft LZG-1 / Extech CT40!
With this gizmo, you can trace up to 16 wires at once. The system uses a remote unit with 17 alligator clips (16 + one for the common/return conductor).
The remote unit sends a 5V pulse width modulated “square” wave to the main unit. Clip 1 is a ~52% duty cycle wave, and Clip 16 is about 98% duty cycle – at 32 Hz. This allows the main unit to distinguish between each wire reliably – as long as the resistance of each wire is less than 30kohms (which is pretty high).
The main unit also doubles as a DMM. Although it’s not the greatest digitial multimeter, it’s good enough for most applications.
Everyone likes to throw things away.
But nobody likes the sight of an overflowing trash or recycling bin, and even fewer people like to take out the trash.
What if I were to tell you that with a simple Life Hack, you could save bin space and time?
What would you pay for such a hack? $19.99? $49.99? $199.99? $1,999,999.99?
Well, watch this vid for FREE… and BE AMAZED!
First, remain calm. Second, watch this video!
A tripping circuit breaker or GFCI/RCD/differential breaker can be really annoying. It normally doesn’t happen.
When it does, the end result can be that you run around the room with your undies on your head, screaming like a wildperson.
Obviously, if your vacuum cleaner is charred and black and there’s a funny smell in the room, you’ve just figured out why the breaker tripped. But usually, the problem is a bit more subtle than that…
It turns out that with a bit of work, you can often cleverly narrow down the problem to one gizmo and save yourself some money – without setting anything on fire!
Let’s say you upgrade the graphics card in your puter.
You fire it up, and it appears that Windows 10 is booting.
The hard drive light is blinking away, and you might even hear a startup sound, or you can see that your ethernet port light is blinking away madly.
Only trouble is, your screen is blank!
What to do, what to do?
This isn’t exactly “techie” in the traditional sense, but it does involve friction, and it’s super-handy to know. Actually, I thought everyone knew about this, but apparently not.
What to do when your wooden drawers are sticking?
Easy! All you need is any old type of candle, a hand, and a mostly-functioning brain.
Anyway, I couldn’t resist making this one of those “Life Hack” videos. I hope this tip transforms your life in ways you cannot possibly imagine. 😜
These days, LED bulbs are all the rage – and that also now includes LED replacement tubes for fluorescent light fixtures. As of May 2017, these LED tubes are relatively new.
They are also frequently more complicated to install since you can’t always just swap the tube and fire it up.
When you factor in light output, power consumption, ease of installation, and cost, are they really worth it?
Ultimately, it depends… But this video will give you an idea of what to look for so you can make up your own mind!
By quasi-popular demand: What do you do when you replace a fluorescent tube in your light fixture, but it still doesn’t work right?
Includes basic description of starters and the two main types of ballasts in fluorescent tube lights.
Watch below, and you can save money and impress your friends!
Well, at least you can save some money… 😉
New Version! See: A better Stylish Smartphone Faraday Box
With the release of WikiLeak’s “Year Zero” information on the CIA’s capabilities, you might be forgiven if you’re worried about your privacy.
Of course, those capabilities were always there, whether you knew about them or not.
Still, it’s a bit annoying to think that some bozo is remotely activating your smartphone’s mic to spy on your extremely dramatic dinnertime conversations.
You could buy some overly expensive “Faraday Bag” to stick your phone in when you’re not using it, but who wants an ugly black overpriced lunch bag?
Instead, just make your own Faraday Box. It’s stylish, it’s hip, and it only takes about 10 minutes to make!
Let’s say you’ve got ethernet cables running all over the floor because you don’t want to use WiFi.
Or maybe you want to install another phone jack, but you want to route the cable nicely along the baseboards.
Of course, routing cables inside the walls is always the prettier option, but it’s also not easy to do in a finished house.
Well, I have a new friend, and she’s a hot glue gun. As her name implies, she’s rather attractive – and very handy when it comes to routing those cables in no time flat!
Superglue is awesome.
Originally discovered in 1942 by American scientists who were trying to come up with good transparent gun sights during WWII, superglue is the “sticks to everything” goto adhesive for all your gluey quick-fix needs.
And frankly, until you’ve superglued two fingers together, you really haven’t lived…
Anyway, there’s probably a lot about superglue that you’ve never heard before. So, read on, and then you can go impress your friends with your amazing knowledge of cyanoacrylate adhesives!
