Well I wanted to use my iPod in the backyard using WiFi internet radio. Are you too cheap to buy one of those fancy expensive ipod amplifiers. Well what better way is to use a amplifier powered by those incredible little Eneloop batteries for dirt cheap.
I used a old beat up radio that I got at a thrift store for $1.50 gutted it and used the shell, including the battery compartment, speaker, amplifier and of course my iPod and bang, portable loud internet rechargeable radio that you can use for years to come.
Step 1: List of Items Needed
*Old radio; $1.50 at thrift store non-working
*Amplifier (from the original radio it self or from something else like portable speakers); $5.00
*Eneloop batteries (my radio needed 4 "C" size batteries); About $20.00 check on Google
*"C" size adapters (or "D" size adapters whatever your radio needs); $5.00 for four
*male to male 3.5mm connector; already had one laying around
*and a ipod or media player; already had mine
*Hooks and Loops (Velcro)
*Multimeter (it helps)
*Spare wires for testing
Step 2: Gut the Old Radio
I used the screw driver to take out most of the guts.
What I left was the tuner dial, all he swiches and knobs to glue on later, the speaker, and the head phone jack to use to plug the ipod into and the AC/DC switch to use for on/off.
The point being is to leave the radio looking normal from the outside.
This part is optional:
I still wanted the tuner dial with the station numbers to work.
The dial moves by a string and pulley system.
I cut the string short and then tied it so it can move the dial on the radio, purely aesthetics.
I then placed back the dial into the radio compartment and it moves as if it works. Great!
Next putting in the amplifier.
Step 3: Amplifier Installation
After opening up the amplifier I found the positive and negative points on the circuit board. I attached two wires. One wire to the positive and one to the negative. I found this out by the multimeter and trial and error using the batteries.
After closing up the amplifier I applied Velcro to the back of the amplifier and the radio so it wouldn't rattle around inside the radio after I closed it up.
Next wiring it all up.
Step 4: The Wiring
Next hooking up the head phone jack on the side of the radio. Originally this would be where you would hook up your head phones so you could listen privately. I made this the jack you plug your ipod into. I found out the leads by, you guessed it, trial and error to find out which connectors to use.
See the black and white wires out of that tan box on the side of the radio. I hooked these connections up to the amplifier's male jack and used electrical tape to connect it all together.
Next the power hook ups.
Like I said before the amp uses about 6 volts to operate and the old radio originally used the same voltage to power the speaker. So I found the leads the amp uses and hooked up the radio like this: BLACK to BLACK but before hooking up the the RED to RED I found a switch that was origanaly used to switch between AC and DC power. So now AC is now off and DC is now ON.
The LED on the amp came on and magic is just around the corner.
Closing shop next.
Step 5: Batteries Hook Ups and Closure
Then placed the batteries in the radio.
Then closed the radio up.
Next pure rechargeable bliss!
Step 6: Finally Enjoy.
The volume is excellent it goes quite high much higher than the ipod could do by itself.
The total cost: about $32.00 much cheaper than one you would buy and that includes the Amazing Eneloop rechargeable batteries.
Now kickback in the back yard with your favorite beer (or soda minors) and listen to famous sounds of internets' radio. Enjoy!
