I made an mono Audio Amp using a TDA2003 and some goods using below schematic.
(I used an instructubles circuits using this link)
And I used an Old 6Ohm 8W TV speaker below!
Finally made the circuit on a breadboard!
(Blue = 12V, Green = L in (Mono), Brown = GND)
(Please don't judge the crappy breadboard wiring; Because I had a shortage of jumpers)
Then after plugging it in; this happened!
Part 1:
Part 2: Running on 5V DC
Part 3: Running on 12V DC
So unfortunately I couldn't find any solution to smooth this out. (You may hear the HDD startup and running noise clearly in Part 3; so maybe the HDD is interfering other control circuits)
The problem is that I was thinking to mount this circuit inside the PC case. (So maybe more interference with HDD)
Any solutions? Can anyone help me to fix the interference(or the noise)? Is it not mounting this in the casing good?
