job offer: pcb-layout

[TobWen]

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...

 

[EnvisionAudio]

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.

 

[TobWen]

Eagle, Protel, Target, Sprint, Pcad, Proteus, OR Boardmaker

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).

does your school give free PCBs?

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

 

[peranders]

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.

 

[TobWen]

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.

 

[TobWen]

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

 

[tiroth]

Well, I just figure commercially speaking, a couple of hours of somone's time at $17 an hour or so is pretty cheap, especially for a one-off job. The person doing the work must be getting paid only $8-9 an hour tops.

I agree it is a lot for a circuit that you could P2P in the same amount of time for free.

 

[TobWen]

if I had the money, or if that would be a commercial thing => OF COURSE, I would pay it.

but this is just a small thing for my DIY projects

 

[tiroth]

Tobwen, I think it is perfectly fine, I was just surprised that the commercial cost was so low. If you can get it done even cheaper by a hobbyist, even better.

I love using PCBs, I just find that it is usually not worth the investment in time unless I need more than a few. It is nice that so many people donate their work.

I would say it's dirt cheap, at least in the western world.

Seriously, if you haven't got the time to CAD it, do you have the time to build it? One solution is to use Vero board.

You may check with Jan Dupont, nick here is ACD. He says somewhere at his homepage about free CAD help.

yes because I can take everything to soldier to university and do it in my free-time there.

I already did it on Vero-board, but I need a "case(d) solution"

 

[richie00boy]

Don't you have access to PC at university? You could do the design in your free time

I also agree that the price is astoundingly cheap.

 

[TobWen]

Don't you have access to PC at university? You could do the design in your free time

they are running Linux and of course, I am NOT allowed to install any software

The circuit is pretty simple - actually vey simple. I own a circuit design company, and use Eagle all day anyway. If you just need a simple single-side board layout, I can do that for free. It's no skin off my teeth, and I'd be glad to help.

Limitations on file handling will be in place as I won't be responsible for actually making the circuit board - you will have to find someone to do that (just as I do). I will give you the Gerber files and the original Eagle .brd and .sch files.

I won't even put my company logo on it.

Send the details along with component values and wattages to

The usual spam-free implementation.

Hey ...

I'm a IPC certiified PCB designer (CID) and haven't worked that cheap in 20 years ... that being said ... I'm a DIY too and would be GLAD to HELP for FREE !!!! .. but .. since I do this for a living ... I don't use those tinker toy tools .. only full mainstream CAD tools .. PADS , Boardstation , Veribest , Allegro ... I'm currently using PADS at the day job and can lay it out in about 15 minutes making that 34 bucks sound like $150/ hr Since I'm a DIY I can also get protos SUPER CHEAP !!!!

let me know !!!

A latecomer, I see. I already delivered it with a BOM for him last month. Tinkertoy tools? I don't have any problems with Eagle Pro 4.13, to which I hope you weren't referring.
