Do you want someone to etch you PCB design or finish the layout?
another try, now single sided...any comment?
the upper side (which invloves oscillator, switch,etc..) gives me hard time now...i need someone's help
another thing, how do i make 12Vdc power jack( to replace Y1) using Altium designer?
Hi t.man,
a PCB design depends a lot of how connectors have to be used. If the connection sequence is fixed (e.g. connector for an LC-display) the connector pins must be connected in the same order the display requires. Other connections might vary according to the easiest (aimed for single layer) way of routing.
Your latest (single sided) example shows a big gap to fill to complete the PCB design single sided.
Getting too close to the screen you won't see it (at least not easily). Stand back a bit and take a sharp look. The gap is exactly where you wasted precious space.

Of course I can and I will.
The software I am using is Eagle. I'll take your latest picture and do the changes using that program.

Nice work Boncuk! R1 could be place just below S1. and Ground could be taken to Y4(pin3) from middle of the IC eastwards and then vertically UP, instead from the Capacitors point to avoid interference.Hi t.man,
here are two ways to route the reset button to R1. There is still a third option moving R1 to jump across VCC and route the left pin back to S1 using the space between connectors Y2 and Y4. In that case S1 has be mounted oriented vertically.
I'd prefer solution one since the reset button is not obstructed by connectors.
I omitted the bottom part (everything 'south' of the MCU).
Be advised that schematic and PCB are not consistant, causing problems when trouble shooting.

Hi t.man,
first off I suggest to leave the power connector as it is. DC-power jacks are very bulky regarding pin sizes. No (affordable) PCB layout software is able to make a solderpad slotted 2.5mm long and 0.8mm wide. Placing the solder pads at a pitch distance of 1/5 inch (5.08mm) you might use screw head terminals.
I already made an improvement suggestion to CHERNG WEEI TECHNOLOGY CORP. at Taipei/Taiwan for a DC-power jack using pins for through holes fitting on a PCB easily using standard solderpads. (things are going slower in Asia than in the rest of the world)
The import of Eagle data into any other software will be difficult, most probably impossible.
You might download the latest Eagle light version (license free) and use the files as they are made using Eagle v. 3.55. The PCB size limitation of 100X80mm is only effective if you want to create a board. Opening any board size those restrictions don't apply (programmer's error, plausibility check in the wrong placeor programmed back door
)
