Evaluate and critique my pcb design

[rs1026]

Hi guys,

this is my first try to design a pcb. I am using express pcb to design the pcbs. I have designed a single layer pcb for Rod elliot's 24db roll off Linkwitz-riley filter. Also i have designed a Power supply pcb for the same. Please go through the designs and bring out the flaws in it. I am sure there are lot of scope for improvement. I would be gald if some one points out the corrections.

schematic ,pcb and slik layer of filter and power supply is attached.

One way I keep my computer virus free is by not downloading zip files from unknowns.

Why not post the appropriate .gif files instead of asking us to mess with a .zip?

just a note about that: assuming you have an anti-virus install like Norton for example, you can simply right-click on the .zip file and select "Scan with Norton Antivirus..." thus making sure the zip is safe to open

There are 3 gif files in each of the zip file. So that makes it 6 files. It is difficult to post 6 of them separately. As ir was mentioning u just need to right click and check for sanity in case of any doubt.

Anyway since no one is replying to the post its alright. I will figure out and re work my design myself instead of depending on others.

I couldn't get most of the files, just one pattern that looks like the drilling.

EDIT: This zip file contains a copyrighted schematic from Rod Elliott. I have deleted it. You're invited to repost your board pattern- you can use a link to Rod's site to view the schematic.
