Handleiding

The EL wire circuit is pretty simple. It just needs

a power source, an inverter, the EL wire itself,

and connecting wires.

The power source

usually starts out as

direct current, just like the electrical current

supplied by the two AA batteries in the power

source in this kit. Typically the batteries supply

a direct current of 3 volts.

The electricity then runs through the

inverter

. Inside the inverter, there are some

electronic components. The most important

of these are a transformer, a transistor, and

a switch. The transformer consists of two

windings of wire that are both wound around

a common core. The transformer converts

electrical charge in one circuit (the battery side)

to electrical charge in a other circuit (the EL wire

side) through electromagnetic induction. The

transistor is what allows the current to switch

directions back and forth over and over again.

The switch allows you to turn the device on

and off. The inverter produces a high voltage of

perhaps 100 volts but at a very low current.

The DC to AC inverter is absolutely required

because the very fast back-and-forth electrical

charge is what makes the glowing effect

continuous.

Finally the inverter is connected to the

EL wire

. One wire from the inverter is

connected to the thin copper wire and the other

is connected to the thicker copper wire core.

Each meter of EL wire draws about 15 mA of

current, or 1.5 Watts per meter. Two AA batteries

provide up to 9 Watt-hours of power, so you can

run two meters of EL wire for three continuous

hours on two AA batteries.

GEEK

OUT!

CIRCUIT WORK?
