And here is the asambler code that I've used.

I have to say that I am not that much in to programing, but it works. The only problem I have recognised so far is that there is a "blip" when several relays are released at the same time.

besides solutions in code for bleeps,you can always put cap in parallel with each coil

Is it balanced or you were using two boards so you can implement the balance control?

Pred
PS

Could we see the schematic?

what effect could one expect from the caps added? And why?


Pred

It's balanced, one chanel on each level.

The schematic is as follows;

What processor did you used?

You may change the code to make sure that only one relay is changed state at one time.

What do you use for volume control? Do you have the schematic of the controller circuit?

Thanks...

I used th PIC16F84!

I will change the code as soon as I have the rest up and running. But i have to figure out how

The volume control is from the Aleph 1.7.

Hi Zen Mod,

Iím on my way to get the rest together and might soon start to focus on the volume control and a solution for the bleeps.

With elco i asume you mean electrolytic, right? Any hint on the value of these?

And Zen Mod, itís a nice avatar youíve got, Hope youíve read the book.

Thanks in advance

elco - yup - electrolytic

say - that for usual 5-15mA coil 220uF is enough

book ........ not just once ......... even in 40. , that's one of books I read every 10-20 months ......
I like movie too - from which that pic is taken .....
