I think that schematic is very unsuited (illegible) to follow in process of drawing pcb for it. Very awkward.
Man can easily lost and make many mistakes on pcb draw.
I don't know which method Sasho used to draw it but certainly it was worse possible.
Since i am also interested in this design i decided first to redraw schematic and make it more legible, than later to draw pcb for it.
So...here is my redraw.
Not checked yet. It is possible that i made some small mistake (like always). Everybody interested is invited to check schematic. If there are some mistakes, please let me know to correct them.
Thanks in advance!

Hi ivconic
Redraw ver 1.2 changes include:
D9 connected to +8v
R27 , 4.7k

Voltage divider by 2 , included r43 and r44 ,2x10k
Although no problem and power section working ok but better
Use 2x33k
Best regards.

Yes you are right about corrections, i see now my mistakes!
Thank You very much!
Best regards!

(D9 designator is doubled...i did that mistake also, need to be redesignated)

I work many-many years with expesspcb. For me best of all. For pcb i make export pdf file and use corel... mirror etc. For Gerber only factory-expresspcb has this application. Last year i search for software but don't find. Maybe Qiaozhi has solution for us

Hi. Thanks for your answer. I'm trying to create the PCB from the scheme in the file sch. Unfortunately it returns me error. Does someone know how to help me?
The error is:
"The schematic file includes netlist errors that should be corrected"
I open ExpressSCH and try to use "checking schematic for netlist errors" and here some component not have pin number.
Someone have all ready create the PCB scheme???
