Final and major change from experimental prototype to end user product...

From the last posts:

"Final step:

1. Get a correct switch so that I can cover my "DVD" with a cover

2. Getting a LED to light up at its correct voltage as an indicator when the amplifier is powered up

3. Recalibrate the sound of my subwoofer to match with my speakers at desired level (Although its already very good now)

4. If possible, enable a microphone connection to the amplifier as well. Therefore this will become a portable amplifier with mic. Great for small group lectures + music/sound input from CD/computer for presentations! "

After much consideration, I decided to ignore all those objectives first. I repositioned the whole interior first to enable me to cover my portable amp. Well, shifting is a real tiring work as it affects all my initial wiring that I had done.

Before alteration:

Interior placement of stuffs can be seen

Initial prototype under testing

After much alteration until early morning again...

Steps taken:

1. Altered the position of my switch and done!

2. LED lights up after placing a 1000 ohm resistor + soldering to LED. So when it's on, it lights up too!

3. Noticed that the woofer may sound too loud at times, therefore, the switch is brought to front and even placed outer than the cover for easy volume control

4. Microphone project disabled temporary to make way for project progress. I'll get it done later.

5. Interior is fully rewired and tidy upped (Although not much significant difference with before)

6. Added better functionality for easier consumer use. Now all in and out connections can be accessed from the back panel (I'll add output connector for today at the back)

Project progress to be updated. (and lesser progress also)...
