Circuit Design Library
AirBorn Electronics is a custom electronics design company.
We specialize in medium/small embedded microprocessor applications
requiring data communications. Do you have work for us? Please
email (or contact us) and we'll give you a price. This design
library contains examples of our work for your reference
The circuit diagrams and printed circuit boards provided as
examples are quite wide images - often wider than your web browser
window. The file sizes are quite small, as the black and white
images compress well. Use the BACK function on your browser
when you have finished looking at each diagram.
Try viewing a sample circuit diagram first - click the BACK
icon on your browser when you have finished!

Electronic Design Software
Wed, 04/09/2008 - 22:06 — eeshop This page originally facilitated
getting mostly MS-DOS-based Pspice and a couple of other locally
used ECAD packages into UN-L E.E. student hands, so I wasn't
wasting time copying floppies for students. Much has changed
in the last few years and that software is now obsolete. For
the newest, latest, greatest ECAD stuff, EE folks should nip
on down to the bottom of the page where I've put links to
all the design, simulation, etc. software I've been told about.
A small archive that includes some other older tools can be
browsed here.

PLEASE NOTE: I am not an expert on any software listed here.

PSpice
Pspice got purchased by Orcad, and they still distribute some
version as "studentware" for free: see this download
page. And somebody has archived the old Windows 3.1 version:
spice6w1.zip
spice6w2.zip

PADS Schematic and PCB
As an alternative to the Altium software used in the UNL EE
Labs, we used to suggest that students wanting to work at
home use a freeware version of the MS-DOS-based PADS Logic
& PADS PCB.
It was not as well documented as a commercial program, and
the user interface is very non-intuitive. And, plenty of students
have never even seen a PC running MS-DOS outside of embedded
systems like cash registers in stores. But it is quite powerful,
has large parts libraries, and was used in the EE Shop for
some of our projects.
(NOTE: Since we now use Protel for our work, I have not used
PADS in some years and am not an on-line authority for questions.)
Circuit Innovations provides a number of key functions in
the design and development of electronic products, software
and printed circuit boards. We are able to assist you in all
aspects of design, taking your original idea and developing
it into a commercially viable product. Our designs utilise
the latest in technology including PIC Microcontrollers, single
and double-sided PCB designs and surface mount technology.
Our kits and products cover many uses of electronics including
display signs, clocks, power supplies, countdown timers, counters,
home security, guitar effects, temperature control and remote
control.
We are also able to assist you with your own designs and
use our design experience to suggest improvements to PCB layouts
as well as indicating any potential safety hazards.
Our aim is to provide an electronics service to everyone
from the hobbyist to the 'mad inventor' to the commercial
sector. If you feel that we haven't covered your particular
electronics requirement, please contact us and we will do
our best to assist you.
It has a limit on the size of the designs it can do. It supports
a lot of output options and can generate Gerber photoplot
files that can be used by the E.E. Shop IBC Boardmaker system.
To learn about the current commercial version, see PADS Website.
Where to get it . . .
You can download compressed archives of these floppies right
now from the Web, but there are some special considerations
with the PADS files that other archived files don't have and
that you must take into account to be able to install it on
your machine. IT IS DESIGNED TO RUN UNDER MS-DOS IN FULL-SCREEN
MODE; don't count on being able to run it "under"
MS Windows in a command window, and I'd be surprised to see
it work even booted to a Command Prompt on any version of
Windows after 98, or maybe even 3.1. But if you're still determined,
