Get 100% Legal Music Download For As Low As $0.10 Per Track!

The Internet is data.
Data is money. Big money!
The Internet is a very interesting 'place,' (permit me to use the word place).

As it is in real world, on the Internet you get products at varying prices. You may get a can of Coke for a quarter ($0.25) at a shop and get that same quantity at another shop at a dollar per can or more...guess I need to check the Guiness Book of Records for the highest price tag for a Coke.😐

Music is one big business in the real world and on the Internet. You can imagine the millions of dollars a single track off an album make when it sells some few thousand copies on the Internet.

On Music sites such as iTunes Store, Amazon MP3 Store, Google Play Music most tracks sell for more than a dollar. A considerable amount of money will have to be spent to get Music from these sites a few hundred dollars will easily run into thousands of dollars as your Music collection grows.

I will like to inform you that there are legal sites where you can get your Music for considerable cost savings. I am not talking illegal free downloads, I am a strong advocate for doing everything legal.

As you may have known, it is illegal to download most music for free. I do not subscribe to illegal free download considering the fact that a lot of resources go into making music. As the Holy writ says' a labourer is worthy of his wages.'

I have discovered some sites where you can download Music cheap and completely legal. Such sites includes:

1. Iomoio, website:

Registration Fees: Choose deposit amount :

$96 + $96 Birthday Afterparty Bonus

$48 + $32 Birthday Afterparty Bonus

$32 + $16 Birthday Afterparty Bonus

Presently running a promo, on signing up you get $0.32 dollars. Tracks are sold at for as low as $0.10.

2. MP3Panda, website:

Go on and add to your Music collection for less!

Make Your Printed Circuit Board (PCB) Easily At Home: My First Attempt

Recently, I decided to make a printed circuit board for my home built stereo amplifier. The stereo amplifier was built several years back using an LM4752 IC, it requires few external electronic components, runs on 10V up to 24V dc supply. See circuit below.
Picture 1. LM4752 Audio Amplifier
 I chose to build this particular one at the time because I can easily power it with my solar panel set-up and any single 12V DC supply. I built the original on a cardboard with the component connection done with single strands of Cat 5 wire. See picture 2 below.

The sound output was not bad. Over time I have modified the original circuit to get better sound output.
'Nuff digression already…
Materials Used For The Printed Circuit Board (PCB)
1. Plain copper coated board,
2. Off the shelf (premixed) hydrochloric acid / hydrogen peroxide etching solution
3. Permanent marker.
4. Clean water in a plastic bucket (about 3 litres)
5. Plain paper for drawing
First, I drew the circuit on a piece of white paper making it bold enough to see when I flip the paper over
Picture 3. The Circuit for the Schematic in Picture 1 (with some modifications)
(Remember it is the circuit tracing on the flip side that you will draw on the copper coated board).
Picture 4. The Circuit Drawn on Copper Coated side
 This drawing will help you to determine the size of copper coated board to  use. Cut out this size for your PCB. 
Next, with the permanent marker, I drew the circuit as seen in Picture 4 on the cut-to-size board from the step above, you may use a rule to make straight lines. Let this dry for a couple of hours.
Now to the etching of the board.

I used a plastic container large enough to allow complete immersion of the board in the etching solution, and used twisted strands of cat 5 wire to hold the board. See Picture 5.
Picture 5. Copper coated board immersed in etching solution
Immersed the copper coated board, copper coated side up, in the etching solution and moved it gently.
In about 5 minutes the exposed copper will be seen being gradually 'eaten' away. See picture 6
Picture 6. Partially Etched Board
 I had to interrupt the etching process when I noticed the permanent marker trace peeling off. At that point, I simply removed the board from the etching solution and wash it in the water I kept close by.
To remove the remaining unwanted copper, I had to re-draw the circuit on the board again with the permanent marker and repeat the etching process. Tracing with a better etching solution resistant material will solve this problem…any idea?
See the 'completed' board in Picture 7 below.
Picture 7. The ‘completely’ etched board
After repeating the process for up to three times I decided the etching is good enough, I then used a sharp razor to cut copper areas between very close tracks away.
Afterwards, I cleaned off the marker traces that remained using premium motor spirit ( that's what I had readily available, you may use methylated spirit.
Then came drilling of holes for the electronic components on the board.

*In my next attempt, I will find a way to make the circuit trace more resistant to the etching solution.
*I will get hydrochloric acid and hydrogen peroxide to make the etching solution with the right concentration.
