ability to do a full-screen display mode on X11 based displays to eek out the most available screen space. Full screen mode disables the window "decorations", borders, title bar, etc.

One of the nice things is that some services will actually order and kit the parts for you - you send them a board design, with a parts list from digikey, and a couple weeks later, you get your boards back. It's not super cheap, but it sure is convenient.

putting a few things on yourself. I’d guess that 90% of the parts on a typical board will be things they can supply. Is there another gotcha? Not at all clear (yet). The outfit above has two categories of parts (basic and extended). It appears that when you go into the extended group, there may be some minimum order gotchas ….

laying out boards by hand, taping up the artwork 4:1, reducing it photographically, exposing and etching boards.  So today's technology is magical.) Many of you are doing some awesome work.  Well done. Wes  N7WS

. I think I'm on to one that meets my fairly simple needs and uses through-hole components.  I have done SMT construction in the past but things have shrunk in size by an order of magnitude since then it seems.  (I can remember laying out boards by hand, taping up the artwork 4:1, reducing it photographically, exposing and etching boards.  So today's technology is magical.) Many of you are doing some awesome work.  Well done.

use, all of the programs have quirks, and require that you become familiar with them. So far I am not seeing any limitations in Kicad that would prevent getting good boards made. And, many prototype oriented houses accept Kicad PCB files directly (for example EUROCIRCUITS) , which saves you from generating Gerbers and drill files. And Kicad just keeps getting better. -- mike On Thu, May 14, 2020 at 4:30 PM Bob kb8tq wrote: > Hi > > I would toss in: > > If you are starting from scratch, pick a program that allows you to easily > enter schematics as well as PCB layouts.
