Dead NOOK.

Hee hee. I thought I was fair at soldering but when the umbilical port socket broke away from the board. Not pin head size pads - pin point. Wave soldered at the factory.

I have 90% remaining battery the unit is shut off.

Have any of you been inside a NOOK Glo Light? The charging voltage is 5.0 and I suspect the Li-On battery to be 3.7

Meaning a charge regulator is in the circuit. Before I cut it's ---- off I would like to save time and ask. The battery is as old as the device - around 2 years. I am going to TRY at the utter end of things to open the unit and connect a pair of 24 gauge wires to the mini port to regulator circuit. If I can do this, I will recharge the battery manually using my lab power supply.

Second if. If I like what I discover (easy access to the circuit, when I get a replacement NOOK I am going to rob the battery out of this one and piggyback it onto the reverse side of the new reader then slip the whole enchilada into a "Nook Case". When I detect a noticable loss of capacity with the new reader I'll snip the parallel wires and go single battery.

The NOOK I have now has decomposed its way to a pile of electronic snot. Gorilla tape, missing button, you name it. So the original NOOK is worth two tenths of a cent.

    I know batteries plus stores replace the battery in those things, I assume those are the tiny solder pinpoints your talking about, so all may not be lost. Now how far are you from the nearest one?

    Maybe the port is called a "Micro". See the period in this text on your display? Well that's how big the port to circuit board tie point is. The battery is fine. The plug-into with a cable port is g-o-n-e

    Hmmmm I see Nook's on ebay with 16 Gb they are going for $24.99
    662 miles you say,,,,,, hmmmm
    3 days time,,,,,
    about 500 litres of petrol,,,,
    and $40.00 for the battery,,,,
    And you could take a shot at salvaging, Are you feeling lucky?
    :B

    Nook Glo circuit board pix

    inside the nook..google short link



    link to picture on web


    looks like the charge port on the LEFT, why not splice in the Male end of a USB, then it could be plugged directly into a USB charge port

    make the pigtail as long or short as needed

    ALLelectronic has pigtails that would fit the battery
    pretty standard stuff
    run a pair of cables out ?
    plug them together to use the nook, unplug them and plug in charge cord to charge the battery ?

    google search Nook Glo images

    In Mexico, broken glass, a crushed Tecate can and straightened nails are "standard stuff". Anything above that is nuclear fission grade tech. Never looked at a MICRO to see which are the power wires.

    Going to the charge control, which of the two wires is which polarity. They are dead until current flows and the Micro make cable end is awful small to probe.

    This is the reason I elected to choose the "tap directly into the battery wires" route. But if someone has the correct female MICRO receptacle with correctly oriented pigtail I'd definitely choose that route. Didn't know an industry wiring code exited for these gizmos. Live and learn :)

    The new NOOK gets the Micro receptacle GOOPed.

    A hundred thirty bucks for Chinese grade junk :(

    Article .. cracking open the nook touch with glow light

    adding wireless charging to nook glow

    the article is about adding a samsung wiress charge pad inside the nook
    whats important is the (2) easy to use solder connections
    use the same connections for other chargers


    Whilst the PCB on the Glowlight is far more densely packed than the Simple Touch, and some of the test points are absolutely tiny, this modification turned out not to be as difficult as expected. The only points you need to access are reasonably large and marked GND and V-BUS. They’re on the more accessible side of the PCB even though the USB connector is on the other.

    A Freakin' Gold Mine You Have Mr Wizard! Woo Woo! Next weekend I will be esconced in Ensenada and I will have 4G cellular and will retire the sundial that measured the ping down here. I am on celluar for this. Tomorrow I will copy to disk all of your info.

    Any idea of the cost od inductive charging? I am going nowhere opening the site.

    You may now have an idea of just how bad off the old NOOK is. I am going to rob its battery and slap it onto the back of the new 129 dollar NOOK. THE Glo Light sucks power like a vampire.

    I re-read my post and dang I could have made it clearer. What I specifically meant was here I am down here. If I purchase a socket does it come with a pigtail and with an ereader the device actually can be connected to a USB port to download entire files into the Nook.

    Because companies comply with the LETS DEPLETE THE EARTH'S RESOURCES AND MAKE NOTHING WE SELL REPAIRABLE Barnes & Noble and too many others do not make repair parts available. The freakin' environmentalists want to start a campaign that would actually do something, make it federal law that no electronic gizmo worth a hundred dollars or more can be sold unless it is repairable and has a parts distribution network.

    for wireless charging, you need both the receiver/charge pad
    That goes on the outside of a phone/device, (inside if the device is big enough)

    And the charging station, which is usually a round puck/plate
    You place the phone/device on

    You can get receivers for approx $10 on Amazon
    Transmitter/station/inductors range from $20 up
    I would suggest staying away from up right stands designed for a specific phone device
    As they may not align probably with receiver placement inside an ereader
    Afaik they charge at a slower rate than a wall wort
    Designed for convenient overnight use
