how to make this lamp shade plz ?

[joasan18]

i think the usb have 4 wires right? we only use black and red what about the other wires?

[hsarode1]

Ya we have 4 wires but we use only 2 they r red and black because they r power cables while green and white r for transfering Data .

[godofal]

red and black are the power wires, the other two are for data, but we dont need to exchange data.
to be clear:
red= +5v
black= ground
green= data ground
white = data +

[knektek]

i had thought that negative ( red ) was ground and positive ( black ) ws +5v.

[hsarode1]

U r rong godfal is correct

[knektek]

... A bit delayed don't you think ...

[godofal]

google it if you dont believe me ;)

[knektek]

oh im not very good at this sort of stuff and i he alot on my mind right now lol.

[mikedoth]

How hard would it be to mod this to use a couple LEDs?

[led235]

basiclly, just get a few White or any colored LEDs and hook them up to a 1k resistor. The output is 9 volts out of a USB plug

[natrinicle]

Actually the output of a standard usb port is 5v at 500-1000Ma depending on the controller card.

[Callum Snowden]

Yeah nominally 5VDC @ 500mA

[Yerboogieman]

i'd just get a few 5v - 6v max LED's and hook em up, maybe a resistor to make the LED last longer...

[mikedoth]

Thanks, i'll see if it works and report back soon.

the orange thing is called a<br/>2-Position Dual-Row Barrier Strips, and can be purchased at radioshack for $2.29. You can buy bigger ones for more money too. Here is the link for both big and small.<a rel="nofollow" href="http://www.radioshack.com/search/index.jsp?kwCatId=&kw=barrier%20strip&origkw=barrier%20strip&sr=1">link</a><br/><br/>Here is the link for the smaller one . <a rel="nofollow" href="http://www.radioshack.com/product/index.jsp?productId=2103228">link</a><br/><br/>I am sorry but the link would not move from in between (and & small)<br/>

[Callum Snowden]

Or they can be called terminal blocks, choc-blocks or terminal strip :) (just so you can do a search on them)

[ShampooRobot]

couldnt i just attach those red and black USB cables derectly to the bulb? without that orange thing?

[godofal]

yes, it can, but it would be harder to replace the light bulb

[Tututu]

Thanks a lot for that idea I made it with an 3.8V bulb My usb cable was 4V So now I made a greate flashlight 5/5

[joshbond_2007]

at first i thought the glue said butrape i hate dyslexia

[mister2]

i really, REALLY don't want to sound like an idiot, but what is, and where could i get one of, the orange thing?

[Bartboy]

Do you mean the scissors or the terminal strip?

[dude300]

an electrical shop like maplin

[poobajones]

what are they called?

[n0ukf]

Terminal strip.

[GitarGr8]

I'd call it a terminal block, or terminal base. We use something similar that mounts to din rail for our control panels at work.

[dude300]

i actually dont know

[Geod]

There's no need to solder the bulb, simply use a bulb socket that comes with a positive and negative lead.

[n0ukf]

Using LEDs (depending on how many) would give you more light for the same power or use less power for the same light output. And you can tailor the color of the light by combining different colored LEDs (give each its own current limiting resistor since white, blue and UV LEDs have a higher voltage requirement than red, green and yellow).

[Yerboogieman]

i did kinda dis on your flashlight but this seems more useful so you can see your keyboard perfect instructable, looks like one of those chinese lamp things kinda
