  1. CarNetix P2140 (part 2) - Power your laptop with Goce from mp3Car

    by , 06-15-2009 at 07:57 AM
    Goce from mp3Car will walk you through the steps necessary to power your laptop using unregulated ~6~24 volts with only the p2140 and the wire your laptop power adapter came with.



    -For this project you need the following materials:
    -p2140 and 8pin molex output harness
    -Wire strippers 14-22 gauge
    -Bench battery
    -Multimeter
    -Shrink tubing and heat shrink tubing gun OR electrical tape
    -Solder gun and non leaded solder
    -laptop and its power brick
    -knife or scissors

    To finalize this project you should do a continuity test on the stripped wire to find out which is positive and which is negative. Then you can twist and solder the p2140 output wires to the cut laptop brick wires. Turn it on to test it one more time, and then plug it into your laptop to test.

    Goce from mp3Car will walk you through the steps necessary to power your laptop using only the p2140 and the wire your laptop power adapter came with.

    -For this project you need the following materials:
    -p2140 and 8pin molex output harness

    -Multimeter
    -Shrink tubing and heat shrink tubing gun OR electrical tape
    -Solder gun and non leaded solder
    -laptop and its power brick
    -knife or scissors

    The basic procedure here is to cut and strip the laptop power brick, while NOT cutting the multi-strand wires right beneath the black plastic. Then soldering the positive wire of the primary output from the p2140 to positive end of the now cut power brick cord. And then the same for the negative.

    In the next video we will show you how to test the polarity using continuity and then actually test turing on the laptop using only the power from the p2140 (through the bench battery of course)
