My Recent PCB arts. What you think

[pasanlaksiri]

I just finished it. Its for my simple clock. I hope to add all the projects files in electro-tech project page little later.

How is my arts ?

Nice work...

 

[pasanlaksiri]

Thank you Mike2545

 

[Techie7]

Awesome art!!!

 

[DirtyLude]

Very nice and clean. Aren't those 0.1uf capacitors supposed to be decoupling capacitors for the IC?


EDIT: You can remove two jumpers on your 7 segment board. 1. by going over LED1 with your F trace, 2. by going under LED2 with your C trace. I think there's more, but it's hard to see the traces with the silkscreen on.

 

[pasanlaksiri]

Yes they are. You can clearly see the decoupling caps.

 

[DirtyLude]

Yes they are. You can clearly see the decoupling caps.

Then they are supposed to be as close to the power pins of the IC as possible.

 

[pasanlaksiri]

Then they are supposed to be as close to the power pins of the IC as possible.

Yeah agreed. But if I do that. PCB size will be little bigger.

Actual PCB size is 8 X 4 Cm.

Yes I agree with you. My PCB is not perfect. Actually what I want is print it and take some fun.

Thank you for pointing me out those.

Well, when you said "How is my arts?" I thought you were looking for criticism of the actual routing and placement. Otherwise I'm not certain what you are looking for other than yes, it's very pretty.

 

[dougy83]

Yes. Looks good in blue.

There's no buffering to drive the LED displays. You might find the displays are very dim.

No need Sir. Im not even using resistors. I limit the current using the software. Im using RED colour displays. So the brightness of the display is pretty good.

 

[dougy83]

Well, in that case: well done.

 

[mneary]

Very well done. One comment I have is that the chip Vdd should have a bypass capacitor after the diodes. I don't understand the purpose of the 10k resistor, but it's an ideal location for that capacitor.

 

[Gayan Soyza]

Very nice.Don't you like to rename that diode comes from battery to a schottky diode?ex 1N5818 etc....Doesn't matter what people will apply but is technically correct.
its your choice

That is to make sure the RA4 is low when there is no AC power.

Yes agreed. But if i change it. People will call and ask what is the most suitable diode for 1N5818. So I use parts that every child on the earth even know

 

[pasanlaksiri]

Finally its looks like this.

[mvs sarma]

It is LOVELY and I would rather comment that you know the ART of presentation. All the best.

 

[Dr. Evil.]

Nicely done! I hope to have the ability to make boards and things that look like that some day.
