Finished a PCB... Thanks to Qiaozhi for fast modifying.

Qiaozhi, did you buy a legal relise on the site? does it Gerber format converting?

Updated PCB

Here is the latest version with some changes requested by 1843:

1. Increased pad sizes for Q4, L1 and D1.
2. Also increased track widths around these components.
3. Reduced C10 lead spacing to 0.2".

Help to design a PCB for my PI design !

Hi all,

Do you know who is this Unregistered?
He is the designer of Pulsdetektor (or at least a friend of his). If you have any demand from him, feel free to ask. I think that Eugene52 is very eager to do so!
See here: 1&2

About my PI:
I haven't built a PCB yet. I wanted Qiaozhi to make some changes in layout, but he is busy at the moment and needs a few days.

Best regards,
1843

Hello 1843 , our friend here !!!. You know my whole family is German and came from Germany , and a few from Poland , But that is not the problem !! I just do not like Greedy people , especially from Germany !! The webmaster and designer of Pulsedetector , lets everyone download for free "all the Garbage "non-programable" P.I. circuits" .......He posts only schematics and front panel photos of the excellent and "Very impressive" Programable P.I. designs , but no program/hex files are posted or included . He has a hidden agenda to get you to buy his high-priced products . I give him great credit for his electronic Engineering and designing , I know his top-of-the-line metal detectors are very impressive and expensive . I guess I do not understand the purpose of his web-site and why he gives us all his Garbage circuits for free . Maybe someday Chris / Pulsi will be honest and explain to everybody here "Without Lying" what is the true purpose of his website ???? Is that too much to ask after all these years ?? ....Also before I forget , nice work you are doing here 1843 !! And I am sure you appreciate the help you are getting from others !!.................Regards..........Eugene52

So you intend to start dozen of new threads relating to this ?
Super! At least good to know sad future of this, once nice forum!
Making intrigue of this funny project doesn't mean it will attract some attention here.
Whatever you do, it will stay just ordinary, poor performances pulse induction funny toy .
Just spare us of starting hundred threads more. Keep you small ideas on one place, please.
Do not polute this nice forum.

Maybe you think your code is Lorenz? HA! Ha! an cant supply?Remember!maybe you take codes from Sisco design an use as your own for Atmega8?for this copy!very similar!

I use Sisco's code with the hardware of Miner!

How about a nice Cup of STFU ?

Alright, ASAP I make it and test the software.(Within a few days)
Auto-tune was added successfully!

Kind regards,

IMHO I think this is now good enough to create a prototype.

Please keep us updated with your progress on this project. We will expect lots of photos and test results.

Qiaozhi what program did you make that layout with ?

IMHO I think this is now good enough to create a prototype.

Latest ECO:

1. Moved PC1 net to junction of R25 and R27.
2. Changed value of C1 on schematic to 4700uF. Value was lost during last update.
3. Recreated copper pour using thermal pads. During the last update the copper pour areas were deleted and redrawn. Some of the properties were removed during the process.
4. Moved C10 closer to PC0 on the ATMega8.
5. Decreased pin spacing on C11 and C12 to 0.2".

Given the small size of this PCB, with thick tracks and wide spacing, I would expect this layout to be relatively noise free. I do not have the time (or inclination) to drastically change the layout at this time.

Hi 1843 ,
I think you are sure enought that you wont need to upgrade this schematic.
otherwise you will have to wait for another pcb
take care.......

I don't want...
Just it's a suggestion to those who are interested to design a PCB.

To keep analog signal paths as short as possible, I suggust the following PCB configuration:
