Picture of make a low cost desk LED lamp
When i play my favorite game during the night (see BF2) its tragedy to try to fly a Jet because i can't see the keyboard...Of course i have a desktop lamp but its a spot light and disturbs my wife's sleep. So i think what exactly i need....I need a discreet desk lamp powerfull in short distance but not distubing others. Recently in the market i found small 3 led lamp with strong light. I bought two of them. The basic problem came after 2 weeks...The adhesive tape wasn't so good and the lamp fall down. Also i had to replace the 3 AAA cells every month......that situation start disturbing me now...So i decided to convert the 3AAA lamp to a USB lamp from my usb HUB, but also i had the problem of the holding the i created the desk lamp....Lets start

Step 1: Lets see the materials

What you will need is:

the most difficult of them is the copper my country can be found in hardware stores in pieces of 2m each. If you can use anything else might be ok. ABout the RCA connector i will explain in farther step why we need them but if dont want them skip this material too.

Also you will need a bench press for manipulating the copper wire

All the construction costed less than 10 euro (14USD)

Step 2: Preparation Step1

Now let me give you some informations about the USB connectors.
The USB connector gives 5 volts in the outlet. The connection inside the connector is: see figures

About the RCA why we need them? Once you make this construction without the RCA if you need for an other reason the USB power then u have to built again from the start to find other USB connector and solderin and etc. Thats why i builted this instruction with cables sets that can be appart any time. The main cable is between the USB connector and the female RCA and the secondary cable from the male RCA to th lamb. Also i remember to use stanard polarity so the center of the RCA is Positive ALWAYS....

I did this with one from the dollar store and after five minutes of being on I noticed that the back led was not working. Either I soldered to the wrong spot or the led broke.

Maybe these from 1 $ are not the same like the philips one! And yes need little care while u soldering the cables. Try again and if u need any extra advices just call.....

I have filed this for future use. I especially like using the old CD's for the lamp base. Very good.
