Default job offer: pcb-layout

Hi there,

can anybody please design a PCB for me?
Single-sided, no SMD.

http://tobwen.bei.t-online.de/netzteil/endversion.png

I need an intelligent ground (ground guiding).

Important things to know:
- min. circuit path 0,25mm
- min. distance between circuit paths 0,25mm
- min. lands 1,00mm
- min. whole-size 0,60mm

I would like these formats:
Eagle, Protel, Target, Sprint, Pcad, Proteus, Boardmaker

I can pay you through paypal and wire (bank <=> bank).

Best,
Tobias

Are you building a lot of these? It seems not worth the expense otherwise...

Any reason why you need all those formats? Why not simply Gerber 274X and Excellon files?

I use Eagle 4.13 Pro and am available.

A professional service would take 26 EUR (about $34) for this design.
I am student and perhaps another student can make it cheaper.

i think those are the formats that he wants, as in:
Eagle, Protel, Target, Sprint, Pcad, Proteus, OR Boardmaker
instead of:
Eagle, Protel, Target, Sprint, Pcad, Proteus, AND Boardmaker

it would be impractical fro someone to redo the circuit in ALL of the formats.

however he has T1 which is ambigous as it may or may not fit on the PCB. further capacitors are not labeled. there are few footprints for the circuit, making PCB design more difficult. especailly with things like D8 the zener diode which may be a 1W, or 10W package and where the 1W and 10W zeners require different currents to get the zener voltage.

fuse holders are also a little open ended.

does your school give free PCBs? i know mine does but doesn't really advertise it.

exactly :-)

About the unnamed parts:
I just wanted to give you an idea, HOW MANY parts will be on the board ... to get an idea of price.

The transformator will not be on the PCB (should be toroid).

My university creates the boards (not the layout) for free :-)

TobWen, I see this as an excellent opportunity for you to learn how to do a layout by yourself. This design is pretty uncritical so give it a try and I'm sure you can get good tips along the way.

I know how 2 do it, but the problem is time ...
normally:

06:45 am => train to university
07:15 pm => return from university

Wow, I had no idea it could be done so cheaply.

in my opinion, it isn't very cheap ... for this small PSU (200mA !!)
