So what is the state of making your own circuit boards?

I'm looking into linux based Software Defined Radio and found this  
wonderful device.
Transmit and recieves from 30mhz to 6ghz.

=============================================================== From: Dan Lyke ------------------------------------------------------ Looks like it might require a multi-layer board, but I've fallen back to the $51 for 3 overnighted to you (but usually you can fit several devices on one of those boards) http://expresspcb.com/ a couple of times, and I think pcbexpress.com and a few others have different options. And last time I tried, the ExpressPCB software ran fine under Wine, but wouldn't order there. That may be fixed by now, Wine is getting pretty amazing. Dan

=============================================================== From: Rod ------------------------------------------------------ I'll look into it and thanx. I wonder what original maker used. From what I gathered he did a lot on linux.

=============================================================== From: "32cstyle ." ------------------------------------------------------ The ExpressPCB and PCBExpress I didn't have good experience with. Well, lets say that the design portion was pretty good. Yet, when my design was done. It was going to cost me over 120 bucks for 3 boards plus S&H. I thought I would save the design as a .bmp. Then take that image to a transparency that I would use for etching.The programmers were too smart for that. The scaling was way off. Even when I used photoshop it was off. I spent a weekend learning the software to draw my schematic, and layout the board. Just to find out I couldn't use it. Just know, if you go that route, you'll have to use their product from begin to end.

Then just search for "Eagle file circuit board" and pick a vendor. There are tons. I've got an acquaintance who was doing his own with the "print on a laser printer, iron that on to a board as a resist layer", and... yeah. Setting up to do high quality fine trace circuit boards is a capital intensive process. The people I know who are making inroads into actually doing their own are using small CNC routers (Dremel and some steppers) and cutting away the copper that way...). But that's nothing compared to what a real vendor will give you.

=============================================================== From: "32cstyle ." ------------------------------------------------------ You know, I never thought about using a Dremel. I have one of those and the small bits that come with it. Thanks for that idea.

=============================================================== From: Stephen Kraus ------------------------------------------------------ You can always get inkject cartridges for making a silkscreen of your circuit and etch it yourself. That's what I did to make my Megasquirt ECU.

=============================================================== From: Rod ------------------------------------------------------ I need to just keep a win7 image for times like this.

=============================================================== From: Rod ------------------------------------------------------ I thought about using them. But they won't take gerber files and the project has pregenerated gerber files. ++++++++++++++++++++++ Rod, Thank you for your interest in ExpressPCB. Our manufacturing service is only available to the users of our software. We have optimized this automated service around the ExpressPCB layout program. I'm sorry but we do not accept Gerber or other file formats, and importing is not possible. If you choose to use our software, I'm sure you will find it very easy to learn and intuitive to use. Please feel free to write if you have any more questions. Regards, - Jessica -

=============================================================== From: Rod ------------------------------------------------------ This looks very promising for the hobbyists. http://oshpark.com/ On Fri, 21 Mar 2014 15:49:21 -0400, Stephen Kraus wrote:
