Hannah Montana MP3 Player - Volume Fix

I bought my daughter a Hanna Montanna MP3 player from JC Penny for her birthday. It was on clearance, and she saw it and said she wanted it, so I went back later to buy it.

Well the night before her 4th birthday party, I opened it up, to charge the battery and load songs onto it, so its ready for her.
Well I got it loaded easy, didnt need the drivers for XP.
I tested it and the stupid volume controls didnt work.
So I had to try to fix it for her, cause it was after midnight, and I didnt have time to exchange it before her party.

So I opened the case up, simply with 1 small Phillips Head screw at the bottom.
Then the rest un-clips from the bottom up.








Once its open, peel off the battery pack, that has double sided tape.
Find the 2 volume buttons, there marked on the board.

There are 4 terminals for each volume control. I think they only use 2, thats logical, but the other 2 are for mounting.









I simply added a tiny amount of solder to each of the pins, using a 25 watt soldering iron, and WALLA! they work now.
I'm not sure what pin on them was bad, but it doesnt hurt to touch up on them all.

I dont know if maybe this one was just bad, or if there are others with problems, but I put this out here, in case other people have the same problem too.
Good Luck!

My Mobile Radio Setup

Galaxy 959 CB
I have it tuned down to 1w DeadKey, swings about 10w, with swing kit installed.
I adjusted the tone on the roger beep, and shortened it.
Blue Meter LEDs.
Super Modulation mod. This is the LOUDEST audio CB in the Metro Detroit area. Don't believe me, ask anyone on CH 19 out there.
UPDATED: Texas Star 667V with modified SC1446 Driver board.
Road Devil Red Mic, with modded mic element.

Wilson 1000 Roof Mount Antenna.


Bearcat Scanner.
Blue backlight LED mod done.
Mini mag mount, tuned for VHF Hi freqs.


LED Lightbar
Light + PA/AirHorn Controller

My Base Station Radio Setup

My base station radio setup:

Galaxy 55 Cb/HAM radio.
Tuned down to 3/4w DK and swings about 8w.
I added a "Roger K" beep to it.
The meter now has a 7 color changing LED in it.
I use a old 80's Turner +2 desk mic.
I also have a Land Matic voice changer, that I can put inline.
I have a RF Limited TRB-1 Echo board that I might put back into the radio sometime.
White Tornado 225w amp. It really only puts out about 150w tho.

I have a 102" stainless steel whip on a 10' pipe mounted on my chimney.
I would use a Antron99 CB base antenna, but Im not allowed to have antennas up here, and this is hidden pretty good, and not easily visible.

Yeasu FT-2500M 2 Meter mobile.
I use a simple mobile 1/4wave dual band antenna on a trucker mount, on my chimney. It works for what I need. I wish I could use my good 15' repeater base antenna tho, but Im not allowed here.

Radio Shack Pro-2030
80 Channel, non trunking scanner.
Used to monitor Fire + EMS dispatch.

I used to have a RS Pro-96 Digital scanner, but I was stolen a few years ago.

Galaxy Melaka Blue LED Conversion + Mods

I have a used Galaxy Melaka CB/HAM base station radio that im working on modding and doing a all blue LED conversion on.

To do the Blue LED mod, I needed SIX 5mm LED's, ONE 470k ohm resistor, and a 2digit channel number LED module.

The MODE selector originally used 6 white 12v wheat lamps.
I removed all 6 lamps, and installed the LEDs, watching the polarity of them. They all share a common POSITIVE, and are selected by the ground. I had to remove the main POS wire, coming off the voltage regulator board, and I added the 470k ohm resistor in series with the wire, so it drops the voltage from 12v to 3v.



The signal meter also used a 12v wheat lamp.
I replaced that with a Blue LED and a resistor.
I will probably add 2 more LEDs to increase the brightness, due to the black background being kind of dark to see.

The channel display takes a little work to de-solder the original module, and then installing the new one is simple as long as all the PCB holes are good and clean.
It takes 8 pins to desolder and put back in.



I also added a echo board to the radio and mounted the control in the back.



I added a simple swing kit, and tuned the radio to 1w deadkey, swinging 6w.



I also added switchable talkback. Simply cut D80, and install a switch.
Open= ON. Closed=Off.
On this board, there is no way to do a variable talkback, unless you install a seperate talkabck board.
