i'm just try to build this thing, absolute no experiance with electronics
What dus 15V means see picture and red circle.

pga2310_atmega8515_encoder_resize1.jpg

does it mean you have to connect -15V and +15V or what?
does any one has build this project?

do you have an total pcb board?

Thanks,
Harry

Yes you need a separate +- 15V for PGA2310 ( dual voltage ) for analog part .
Yet another Volume controlers and source selections
Vikt0r and Pryanic build this also , in page 3 to 18 will find info , also I have posted my project from 3 years old on perfboard .
I do not have such pcb board for this but maybe Pryanic or Vikt0r will post files for etching that pcb !
Happy diy !
I am recommending to program the last firmware for PGA you find in this thread .

Default danzup,

The Power-supply board layout is a little different from from the schematic, Is it still safe to use? (particularly around the mains)

Do you have a board layout that tells me where all the parts go for "IS REV 4 A". the board layout in your first post is for a chip source selector.

And may I ask what this is? (I've also noted that many of the transistors are different in the board layout... Is it safe to follow the schematic?)

Thanks,
Kurtis

Ps. Board layouts are done, They didn't turn out so good but they are usable. Going to tin and flux on Tuesday. I'll post pictures when there something to post of

1. yes ! no problems about if you keep in mind that there are live 230V voltage that can kill you !
2. that pcb was made by alexmm from this forum but have been tried by me and they worked .
3. use whatever tranzistors have , just stay with the schematics
4. that is a ferrite 0 ohm wire jumper
We are waiting for your pictures !

Default Thanks Danzup

Safe to leave out the zero ohm ferrite jumper then?

Heheh, in Canada we have only have 120VAC 60Hz, still dangerous, still gives a nice buzz if your not carefull.

Does anyone have any recommendations for LCD screens beside the obvous 16x2 lines. Colors and stuff, known models that work well.

Thanks, Kurtis

A piece of wire instead the zero ohm ferrite jumper is ok .
All Lcd compatible with Hitachi HD44780 will do .

On post Nr.3 :
Sorry but discover an error on pdf
File Type: pdf sch_supply & relays.pdf (26.1 KB,)
value for resistors R39L , R39R and R38L, R38R are swapped !
the correct value are :
R39L , R39R = 11K
R38L , R38R = 53K
