DIY Shuffle charger


[Blake] sent me this one when my house was covered in ice. He put together a charger for his new iPod nano er, shuffle. It’s sort of in two parts: a USB to mini-jack and a 5v wall adapter to USB port.

    I think you mean “iPod shuffle charger”. The iPod shown is a shuffle, not a nano.

    If you buy the iTrip for any iPod you can also use a motorola phone charger to charge it (the iTrip has a mini USB port that matches the L7 charging unit)

    Very handy on long trips (provided you have a car charger)

    I think this would apply to nano’s as well, although the article does in fact say Shuffle.

    All he does is plug his Shuffle’s USB cable into it, I don’t see why you can’t plug a nano’s USB cable in as well.

  5. yeahhh that’s a shuffle dude.

    uhm,…wow, wiring up a 7805,….

    ya, I agree todays mod is not all that great. just a voltage regulator + resistor…

    I’ve seen different circuits for charging usb, and this is the simplest one I’ve seen.

    I built a similar device, but for general application.

    I also used a 7805 5V regulator. It can actually use a wide range of power supplies the specs on the 7805 say up to 35V, but I like to have a safety margin for unregulated wall adapters, so I’ll only use up to 30V or so.
    I added a few more options:
    *I used a standard “size M” jack so I can use any standard DC adapter with that tip – its what the general majority of wall-wart powered electronics use.
    -I also made a 1 inch pigtail from a 9V snap to a M plug, so I can power it with a 9V too.
    *I added a full-wave bridge rectifier in front of the regulator, – not to use AC, but to allow me to forget about polarity when finding a wall adapter. – I used one rated for 100V, just to make sure it would handle the current. (yes I know the difference between V and I)
    *There shouldn’t be any ripples from the 7805, but I also added a 100uF electrolytic cap across the output of the IC just in case.
    *As a cosmetic touch (and to tell me power is on) I added a nice blue LED. there’s lots of 4.5V leds out there, just use a 27 Ohm resistor, or use the resistor calculator on http://www.metku.net/index.html?sect=view&n=1&path=mods/ledcalc/index_eng#

    and why have only one USB port? I made mine with a USB and a 1394 port, but two USB ports would be more useful.

    -I’m thinking of building another one of these. perhaps I’ll make a log this time.

    Look at this…….http://www.instructables.com/id/EO7VZ73NWXEP286ZV3/
    then try to answer my question please…

    i have a 330 ohm resistor, a 33 ohm resistor and a 100 ohm resistor…….which one should i use? i already bought these…i dont want to buy more.

    Hi All,

    So I have an audio mixer on my motorcycle (K1200R) that puts out 9V. I want to charge my iPod as I listen to it. My question is, do I need a voltage regulator (or DC/DC converter) to take it down to 5V or can the iPod handle the votlage overage?

    Thanks!

    Ian

    Thanks for information, I’ll always keep updated here!

  12. Thanks for information, I’ll always keep updated here!

  13. I’m not finished read this yet, but it’s so fabulous ‘n I’ll back again when I was finished my job :D

  14. This is so interested! Where can I find more like this?

  15. I wanna find more info about this, anybody could?
