Yet another Volume controlers and source selections

[Vikt0r]

Hi danzup!
Others also complained on my I'm reading theor thoughts
You'd probably laugh at me, but the main reason I don't want to use perfboard for this project - is that I'm saving my available perfboards for "modeling" projects (I'm greedy to spend money at them ) and because otherwise I have everything available for it, so can make it without attending a shop, also making a PCB from the scratch takes me max. 2 hours - so why wouldn't I make this "as should be" from the beginning? Moreover, SMD components would require no drilling... Moreover - I've got them already

( price for : kit r/2r atmega16 / 4 input without transport to USA is 53 euro , please any other info in pm )
But if you do not like the fade and discrete mechanical sound of relay (this do not propagate to speakers ! ) this is not for you !
In path of audio signal there are only at max attenuation 6resitors and have the most transparent sound of a passive preamplifier .

Hi danzup,

haven't heard from you anymore, but I am still interested in the kit.

If you have decided not to offer them is pretty ok, I would then start the project using your PCB design... and probably be asking a lot of questions during the build time...

Cheers,

Max

After reading the lasts posts properly I thing I was too fast myself as well... I'll just be looking here from time to time.... and wait for the magic PCB...

Sorry, was my mistake, not too much difference in the PCB though.

Now I work very slow. I spent a lot of time reading Romanian thread and I've made some PCB's for my project. Actually, seven (control board, power supply, pony prog, front board for display, LCD and pushbuttons, two boards for inputs and two boards for volume.
I understand some people need PCB's. I can't help Vict0r, but coolnose can use my design. It's not optimized because I don't work professionally. I just used halves of Euro format. I can also send design of other PCB's.
I hope in next ten days I'll have my boards completed and tested.

Nevermind, dobrivoje!
Considering that danzup's friend did not post anything in reply to our requests, I also started developing boards. At first I made a copy of design of the initial board (with DIP casings) in my favourite design tool, now at the next step - I'm making a dumb conversion of the board design in this same tool to PLCC/SOIC. So far seems, that I would need to completely remake the design for this purpose, which is also not a big problem (weekend is coming). Once I'm ready, I'll also share this design (hope you okay with this, danzup?).

Very ok !
Good luck to both Vikt0r and dobrivoje and waiting for both to post here your work !
Soon I will add an passive baxendall tone / volume control project I am working now .
Also : for everyone who make one of projects I will offer full support ( on little time I have now available ...) .

Hi
2 Vikt0r
If its not too late I can post here my PCB version under PGA2310 danzup project. But I dont use any specific soft for PCB tracing, I draw all my PCBs in CorelDrawX3.
If its ok - just ask an I publish it here today in the evening.

2 danzup
"...passive baxendall tone / volume control..." - oh, yeahhhhh!
Sounds good!
I like it even without schematic
...particularly passive baxendall tone control

Thanks to danzup and jkraxi, this project is an open-source now.
You have schematic, gerbers, pcb layout, atmel software for LED and LCD display.
:: vicol audio :: R-2R volume controller ::

Enjoy !

Yes , project nr.3 also go open source and launched group buy for new pcb :
GB for R2R audio volume / input selection pcb

Thanks all !
