were you planning a single sided board or is double sided ok?
Well, now that I've looked at it, obviously you were thinking of single sided. Your layout did not make sense to me so I did my own version, shown below. Here are some tips for designing this sort of thing:
- place components so that connections are as short as possible, starting with those that naturally group together. For example, I started by putting U1 in the middle, then putting R3, C3, R5 and VR4 close to the pins they connect to. Turn them around so that connections are short. Next, place the dip switches and be prepared to reassign the connections for easiest routing. I didn't need to.
- put a ground around the outside so that any connections to ground go outwards and away from the clutter
- place the bypass caps for the IC near the IC vcc pin
- keep traces running either vertical, horizontal or at 45 degrees for a tidy appearance.
- always maintain minimum of .010 clearance between unconnected copper
It is obvious that you did not try very hard to position components for shortest connections. You need to think as you place each part, and not only move them, but also rotate them to shorten the connections as much as possible.
Here is my version (if you post again I will post the design file of this).
