Does anyone know the circuit for volume control for these speakers http://www.woot.com/blog/viewentry.aspx?id=1126?

Here is a link to the chip that handles the volume in these speakers: documentation.renesas.com/eng/products/a... There is a very good post on correcting issues with the volume, you may find this informative: fixya.com/support/t226848-ada745_speaker....

This is the circuit I am using

. I can’t really hear much amplification of the sound, anyone have the same issue? Also I was trying to swap the 10K V resistor for an LDR, so the volume would raise and lower with the influence of a LED brightness attached to a PWMOUT of the picaxe chip.

I wired this circuit as I thought but it didn’t work. Does anyone know how to do this? And perhaps give me a circuit diagram?

At present the volume control of the 10K V resistor from min volume to max volume is only active over a very small amount of the 0 – 10K movement, over about 60ohms. This doesn’t feel right.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
