Ever Wondered What’s Inside This Bead At End Of Your Laptop Charger? Mystery Solved...!

By:Prayag Nao

We all have a basic idea about the purpose of each wire going in and out of our computer. But a few wires seem a bit off when it comes to their appearance. They have a cylindrical bead dangling near the end. So what’s this bead doing on that wire and what purpose does it serve? Today, we are going to unravel this mystery for you.

You will not only find this bead at end of charging cables but also mouse, keyboard and other peripheral cables. It turns out that lump’s called a ferrite bead or, more generically, a choke. It’s a fancy name for what’s basically an electromagnetic wave-bouncer. If you open this bead, you will not find any complex circuits but only a ferrite cylinder that is magnetic in nature. It is this magnetic quality of the bead that serves the purpose.

So basically, when current passes through any cable, it generates electromagnetic interference (EMI). Your electronic gadgets also produce EMI during operation. For example, if you connect a camera to your monitor, the camera would produce intereference and cause your monitor to flicker without the presence of a ferrite bead. If left unabated, EMI can wreck havoc with your computer peripherals.

These ferrite chokes ensure that signals are only sent in the intended directions and no EMI is transmitted between the peripherals. The choke dampens these EMI waves by acting as an EMI blocker. The blocking is most effective when it is near the source of the EMI, thats why you will only find these ferrite beads near the end of the cables. So, this little mystery is now solved! These tiny cyst-like beads make sure that our computer peripherals work properly and don’t cause any issues for the computer itself.

Here's How This Supercool Hoverboard Works

By:Prayag nao If you've ever dreamed of cruising around town on a floating skateboard like Marty McFly does in the classic '80s flick "Back to the Future Part II," then you could soon be in luck. A pair of innovators is trying to make the futuristic fantasy of riding a hoverboard into a reality. About two months ago, husband and wife design team Jill and Greg Henderson launched a Kickstarter campaignfor their Hendo Hoverboard, a levitating skateboard that could hit "hoverparks" as early as October 2015. The Kickstarter campaign , which ends Sunday (Dec. 14), has been a resounding success, bringing in well over its initial goal of $250,000 in its first week. With only a couple of days to go in the impressive crowdfunding campaign, the project has already raised nearly $500,000. But with all the hype comes an important question: How in the world does this thing work? The basic premise behind the technology is something called
