I am in Mirpur visiting the Underprivileged Children's Education programme (UCEP) Technical School. Accompanied by programme managers Anis and Ayub, I trawl through classrooms, photographing the children.
I knew about the seventeen hands-on vocational skills taught here, but seeing their sheer variety opens my eyes.
In the electronics class, a girl confidently identifies the terminals of a transistor using a millimetre while another explains the differences between waveforms on a signal generator. Auto mechanics students show me the assembly of a steering system, while the CNC (computerised numerical control) students punch in digital measurements for precise machining.
All of them aim to become skilled employees in electronics and light engineering industries.

In a large area devoted to garments training, Sharmin is learning how to iron and package a shirt. I ask her if she likes coming to school.
Spray-on Nanoparticle Mix Turns Trees Into Antennas
24.05.12
A small company called ChamTech Operations based in Utah has developed a nanoparticle mix that can be sprayed on any vertical object—like a tree—and make that object act as a high-powered antenna.
Not only can the sprayed-on nanoparticles make trees into antennas, but it can also extend the range of an existing antenna by a factor of 100, according to one of the principals of the company, Anthony Sutera. For instance, in RFID tags the nanoparticle spray extended the readable range of the tag from a mere five feet (1.5 meters) to 700 feet (200 m).
The material that Chamtech came up with contains nanoparticles that when sprayed on a surface act as nanocapacitors. The nanocapacitors charge and discharge very quickly and don’t create any heat that can reduce the efficiency of your typical copper antenna. The trick was to get the nanocapacitors to spread out in just the right pattern.
While watching the unassuming Sutera deliver his presentation (see below), I have to confess to being a bit incredulous.

How do I ground a cb antenna onto a vehicle?
May 13, 2007 by roshambo76 | Posted in Maintenance & Repairs
I want to know exactly what I need to run a ground wire to in order to ground my cb antenna to my mirror bracket. What part of the antenna, mount, or bracket must have a ground wire?
The bracket itself can be grounded . You will have to run a jumper from bracket to somewhere thru the door onto body ground. The problem with most mirrors are they have a rubber insulator At each screw mount to keep vibration of the mirror assembly to a minimum
Baby huey read my answer more closely the mirror is insulated
he has to run jumper

The only ground on a vehicle is a connection back to the Negative pole of the battery, or a connection to the chassis.

IF YOU ARE USING COAXOL CABLE YOU HOOK IT TO THE ANTENA. THE METAL BRAKET YOU USE TO MOUNT IT TO THE METAL MIRROW BRAKET IS YOUR GROUND.

How can I change a power antenna to a stationery antenna on a 1991 Honda Accord?
Jun 27, 2006 by audioswiftt979 | Posted in Maintenance & Repairs
Antenna grinds to a halt when lowering, and makes noise when sliding up. What should I take apart and install?
Dismantle the power antenna and disconnect the plug to it. Remove the antenna and read the directions on the new one. Hook the antenna wire from the old to the new.
Good Luck

I would get the antenna in the upmost position and then find the motor and unplug it while it is up. I did that on one of my cars before. With the motor unplugged the antenna cant go back down.

How can I protect my car antenna from the car wash?
Feb 28, 2007 by LG | Posted in Other - Cars & Transportation
I have an 03 Corolla. The antenna sticks out from the back of the hood and I fear that it might be damaged if I put it through an automatic car wash.
Is there anything I can do to protect the antenna to ensure that it doesn't bend or break?
Thanks.
Some unscrew, and some can be pushed down. Some go down automatically when the radio is turned off. If yours is none of these, there's nothing you can do but take your chances - or wash by hand. This will always do a better job (and be cheaper), but can be difficult in winter.
Also, some car washes are brushless - they rely on high water pressure to remove the dirt. These will protect your antenna, but are bad for the paint, and don't even clean as well as a standard car wash with brushes.

Unscrew it prior to going through the wash.

1. Stop being lazy and hand-wash your car. You do a better job than any automatic machine.
2. Most antennae will just unscrew. Use a small wrench to loosen and remove. When reattaching, tighten it by hand only....then you can remove it anytime without a wrench.

If it's not the kind that can be pushed in than it probably can be unscrewed.
Curious George | Feb 28, 2007
Can you take it off? Try to see if it unscrews from the base. If it does then just remove it and put it back on after the car wash.

How do i remove the power antenna from my 1995 NIssan Maxima?
Apr 07, 2010 by Kirk | Posted in Nissan
In the trunk, there's a piece of metal in the way which makes the power antenna unit hard to reach and remove. Is there an easier way to get to the antenna? Are there some other bolts or screws that need to be removed? Thank you!
You will be happy to know that your car has an antenna in the rear window, the wires you see imbedded above the defroster wires. Just put your long antenna down, disconnect the plugs attached to it, and let your radio use only the window antenna. I'm 60 miles from my favorite FM and it's coming in loud and clear. It's been this way for a year. Do I miss the long antenna -- maybe on a long highway trip. But for urban driving -- no. So just disconnect the motor of your antenna and enjoy the better lines of your car on the road.

Any ideas on where to mount an antenna on my 17ft bowrider?
Dec 25, 2009 by Marlbobama | Posted in Boats & Boating
I'm putting a stereo in my boat, and was wondering where some common spots to put the antenna are. I've never really noticed antenna's on other boats before.
Most boat builders use the windshield frame as the antenna. I know this since all (6 boats) have a wire attached to the metal frame.
