Si Prog Programmer PCB Design: Eagle Project Review & Feedback for First-Time User

Hello, I have a request to you, someone could check if I have done everything correctly. This is my first Eagle project so please be understanding.
It is a Si Prog programmer. I know that the paths would be able to lead better, more minimalist. I will make the plate using the thermal transfer method

place here - in a packed form, eg ZIP or RAR, attach the whole project.
One side of the PCB is not enough to let me check it out.

greetings

Hold it

Hold on to

I caught, but you have to wait for the answer, because today is Sunday ...

Okay, I'm in a hurry

Hello,

it lasted a bit, because I had more urgent matters, and besides, the need was to devote a lot of time to the analysis of this, something here posted.
After removing the black background - tab -> Options / User interface ... / Layout / Backgroud - it looks like this:

My guess is that the designed PCB is one-sided - I do not see it any other way.
And then you have unnecessary guides marked as 1 and 2 and a series of pads "hanging in the air" - all this marked in the red rims.

greetings

As for these hanging pads I do not have any objections, because after using the tool Ratsnest the mass field is poured nicely by combining the previously hanging points.

Only that on - see above - PCB drawing does not show this and no switching on / off layers does not change this.

I admit the right but after removing this polygon and applying the above tools all unconnected pads reveal.

You can not see anything here, that's why I changed the background from black to white - see above - and then you do not see those connections.
I know it is supposed to be so, but I have to check it and not correct it for the author of the subject, so I proceed formally here and see what I see (or rather do not see).

I do not understand too much what's going on and what to improve. For me, how do I download the file that I previously inserted and I click ratsnest GND is properly spilled and all connections are made. Even the first picture is with properly poured GND. These grommets are not unnecessary, they combine the field of mass. And as for the white background, I changed it and GND is still properly spilled, you had to remove it by mistake. Unfortunately, there is no possibility (or at least I can not) save the file so that after opening the mass field was visible was visible, it is always marked with a broken line and only after clicking ratsnest reveals itself
I wanted to check the PCB in terms of functioning or how it will build it will work? Does it have any errors?

Ps. In the picture with the white background that you put in the mass is not visible, therefore it does not prompt you to connect it together but blue dotted lines can be seen, if you click on ratsnest then it would show up.

Look there: post # 10 , is there something visible there?
How do I check the correctness of your PCB as I can not see in the connection drawing?

If you want to see all connections, download this PCB file again and after downloading click on ratsnest in eagle

Unfortunately, but it does not work for me.
Show what you see when you change backgrond to Colored , or White - see here my post post # 11 - I can see this invariably like this:

I have marked you with the option you need to click

And try again, maybe slightly reduce or increase this dotted line and then click on ratsnest. Maybe something got stuck

Thank you ... ... I will check.

EDIT: It worked, but only when I installed a newer version of Eagle - 6.4.0

PS See TAM , I've put there the information about a reliable and free tool - Captura 1.0 - for taking screenshots.

So I'm waiting for opinions about PCBs?
All good?

I will reply at the earliest tomorrow ...

The PCB design presented above seems to be correct and in accordance with the schematic diagram.
It would be worth bolding two paths - thinner than the others - from where it is already possible.

I ran the whole path around Jena (I let go under rs232). And in the second I can not do much better with tin than with the pickle.
Thanks for the help
And yet someone could write which goldpins is miso sck and reset.

You can do it - put a virtual pad on it and then a thinner path on one side and a thicker one on the other.

View TU - this is the accepted standard - but it does not suit me with the standard adopted there and on the site of the original design SI-Prog is different - see description -> AVR microcontroller adapter
Consider whether it is worth replacing this single-row connector with a two-row one.

There is a 4 MHz quartz resonator drawn on that diagram, is it superfluous, can not program the microcontroller on the internal oscillator?

For this answer question, look in DataSheet for a specific ?CPU.

From what I read, it is not necessary. I will program atmege 8.
If I had any problems, I will still write.
