From the board file the board is 23 x 33mm, other assumptions correct.
However remember because you have surface mount and plate through
components
you have TWO different solder masks (one for each side). The solder mask
is what gives the board the green colour.

What I'm really trying to do is to get as many for as little ?? as possible.
I guess the silkscreen (lettering) could go, not important. We were paying
about ?80 for about 100 of those boards in 2 weeks or so. I've put this
to the 4 companies I've emailed.

Well I did a quick check on <http://www.pcbpool.com/> and min order qty
with panelling up they would supply 13 boards per panel 1dm2.

Ordering as Double sided prototype quantities, with NO solder mask, and
just ident and 13 boards to a panel. A quick quote of 8 panels (8 * 13 =
104 boards), and post shipping on EIGHT days turnaround is 69.93 Euros
..........
For what your board is I would consider both sides solder mask for assembly
process as you have tracks between pins, and top side ident so add 34 Euros
to give

103.93 Euros or 71.94 pounds for 104 boards

slightly cheaper than what you had before.

Give them your VAT number and you then remove the Irish VAT rate of 21%
from that and gives a total of

85.89 Euros or 59.46 pounds for 104 boards

That is a LOT cheaper than what you had before and straight from an Eagle
file you transmit electronically.

If you want faster turnaround then you pay more.
......

Wow Paul, I think I love you Not quite appropriate on here but hey I'm
happy, these figures are brilliant. Best quote I managed today was ?160 or
so.

That's the best 'payment' I have had for advice, even in a newsgroup :-^

Will get back into this over the next few days as in hospital on Thursday
and planning to nail this on the head while I recover.

Thanks, will read this properly tomorrow, will likely start a new thread on
it.

Get Hospital over first! Then nail this.

I am sure plenty of people will help out, if you have any further questions.

No. The UV sensitivity is only during the manufacturing process. Once
the board is etched, sunlight is not a problem.

Eg when the conductive layer (copper) is exposed to the etch fluid. It will
harden in such way it become uv-resistent ..?

No.

The bare copper-clad board is coated with a photosensitive material.
A film containing the required copper pattern is placed over the
board, then the combination is exposed to UV light. The board is then
"developed" to remove the unexposed coating, leaving the desired
copper protected by the exposed coating. The board is then etched to
remove the unwanted copper, and finally cleaned to remove the
remaining photosensitive coating, so you can solder to the copper.

In commercial processing, I think the photosensitive coating is
removed over the wanted copper, which is then plated with tin, which
will protect that copper during etching.

Copper itself is not light-sensitive.

If you used bsd-unix you could get away with:

#include <stdio.h
#include <fcntl.h
#include <sys/types.h
#include <machine/cpufunc.h
#include <dev/ppbus/ppbconf.h

I'm trying to learn about pressure transducers and I've learned a tiny
bit on the web, but not found it as fruitful as I had hoped. (Or I just
don't understand what to look for.)

Do they permit air to pass through them, or only into them, like a
pressure tank?

Is their output linear with pressure throughout its rated range? If the
transducer is good from 0-30 psi, then does the output range from
something like 0 to 30 volts? When their max rated pressure is reached
and then exceeded, does the output stop changing? Is it accurate to say
the transducer is saturated?

Would the power supply in this example need to be 30 volts? Does the
supply need to be steady? If the supply fluctuates, does that throw off
the measurement? If the supply is noisy DC, does this throw off the
measurement?

It seems like they are always zero to X psi rating. Can the same
transducer measure vaccuum too? If I want to guage -20 psi up to 40
psi, can this be done with a single transducer? If not, is there a such
thing as using two transducers to measure this range and to install one
of them backwards?

Thank you.

Go here and look around.

http://www.emersonprocess.com/rosemount/products/pressure/m3051.html

The pressure transducer usually just has air to pass into them.
The output can be made almost any way. As you did not state what you wanted
to do, the output in many cases is a 4 to 20 miliamp circuit.
The output will saturate when the maximum range is exceeded. They may
overrange a small percentage. That is if the rated output is for 20 psi
then it may go to 21 psi.
There are transducers that can be ranged from negative presure (gauge) to a
positive pressure.
BTW you can not get -20 psi. Around 14.7 psig is as low as you can get.
That would be zero pressure absolute.

Into or onto them. Some are made like a plug that fits in a pipe
threaded hole. Some measure the difference between atmospheric
pressure and applied pressure, some measure absolute pressure (have a
vacuum on the back of the sensing diaphragm). Some have two ports, so
they can measure the difference of two arbitrary pressures.

Is their output linear with pressure throughout its rated range?

Some are linearized, some produce an output directly from a strain gauge.

If the
transducer is good from 0-30 psi, then does the output range from
something like 0 to 30 volts?

There are many types.

When their max rated pressure is reached
and then exceeded, does the output stop changing?

Most have some over range with reduced accuracy (or some sort of
saturation) that doesn't damage the sensor.

Is it accurate to say
the transducer is saturated?

When additional pressure produces no additional output change, it is
saturated.

Would the power supply in this example need to be 30 volts?

There are many types that operate from a wide range of supply
voltages. Some regulate the current when a voltage is applied
(current loop operated transmitter).

Does the supply need to be steady?

Some do, some don't.

If the supply fluctuates, does that throw off
the measurement?

See above.

If the supply is noisy DC, does this throw off the
measurement?

There is always at least a little bleed through from the supply. How
much is a specification (power supply rejection).

It seems like they are always zero to X psi rating.

It may seem like that, but it is not the case, especially for the two
port types.

Can the same transducer measure vaccuum too?

Some can. The absolute pressure types certainly can. A perfect
vacuum is just their zero scale point.

If I want to guage -20 psi up to 40
psi, can this be done with a single transducer?

With the right one, sure.

If not, is there a such
thing as using two transducers to measure this range and to install one
of them backwards?

Not the best way to do it, but possible.

I tried that but for some reason it didn't work ;/ I'm not sure if it works
for raw bits or what?


Basically I am trying to dump a serial data line to the parallel port and
read it almost like a logical analyzer. This way I can make sure some
devices are working right and such... The only thing that seems to work is
parmon but it doesn't log the data ;/

Jon

Below is the portmon output for a program called jbasic.exe with
the Tx and Rx lines connected together on the com1 port. In this
case the jbasic program sent "hello world" (displayed in hex) to
com1 and then read the com1 input buffer picking up the "hello
world". The lines are probably word wrapped. You may need to have
a device connected to the parallel port for it to see the traffic
there. To setup portmon you have to go to "computer" and select
local, then go to "capture" and select the ports to monitor.
Check the help file for other setup and logging options and such.

If you are using Win9x you can probably cobble together
some code to read the parallel port directly. WinXP, NT,
and 2K don't allow user-mode access to ports, so you'd need
a special ring 0 driver like GIVEIO or USERPORT.

Unlike serial ports, parallel ports are not clocked devices.
So you will have to decide how often you want to look at
the port. Note that timing is definitely not Windoze strong
suit, so expect a fair amount of jitter and don't expect to
get fine resolution (high sample rate).

The hilarious part of all this, is that the earliest 8088
PC running DOS was orders of magnitude better than
the fastest Windows system for this kind of stuff.

hmm, wasn't his first post sorta an attack too?

"There is no electronics question in your post!"

This maybe or may not be true but surely the parallel port is used
indirectly with electronics? I am asking this question simply because I
want to use some electronic devices and monitor there digital outputs... so
indirectly it has everythign to do with electronics... and surely many
people here in "sci.electronics.xxx" has messed with the parallel port in
some fashion or another and probably has had the need to monitor/log the
port?

The fact is this is probably the best place to ask this question since it is
directly used for an electronics application... I could be wrong but he
obviously thought that my OP didn't belong in here and he had to point it
out.

He could have said something like

"You might find better luck asing in blah.blah".

Cause basicaly he's implying that I'm asking something that is completely
off base in this group, which I think it isn't.

And I seriously doubt I would get any answeres in alt.comp.freeware that I
couldn't get googling.

Best regards,

I'm just doing this for the keyboard so I just need it to run from 10khz to
20khz. Its not clocked but if the application could use one port for the
clock to sample another port then it should work? Or even just set the
speed at which to sample?

Basicaly what I want to do is hook the keyboard up to the parallel port and
then hit keys and read the data being sent. I have the parallel port all
setup to do this easy but it looks like I'm going to have to do it with a
serial port since that seems to be the only one with the extensive
applications.

Hi, bb. Assuming you're using external caps for the oscillator and the
keybounce mask, all you have to do is set your keycheck loop so it
happens at least twice during the component-selected debounce period.

Check for Data Available. If it's high, read the keypress data, then
set a software flag. Don't read data while the flag is set. Wait for
Data Available to be low again before resetting the flag. Read data
again when flag is reset and Data Available is high.

If you don't need to tri-state the '922 data outputs, that's the
easiest way. If you have bussed the data, clear the bus and then
toggle output enable to read the data as above. It's all in the data
sheet, available at the Fairchild Semiconductor website.

http://www.fairchildsemi.com/pf/MM/MM74C922.html

If this isn't an exercise in programming, though, the 74C922 is an
expensive way to do this job. If your code is so bound up that you
need a dedicated part to do keypad debounce, it might be better to get
another small uC to do this job at less cost and fewer pins (data can
also be sent from one uC to the other in serial format). You can also
have n-key rollover instead of just 2-key quite easily.

There's no law that says you can't have more than one uC on a board.

Good luck
Chris

If you have a win95/98 machine, you might check the software at
the below site. It is for recording IR signals from remote
controls for replay using the parallel port. It won't work well
with win NT/2K/XP. You might be able to use a similar setup to
record the output from the keyboard. You probably could make a
similar recording setup using qbasic, but actual timing
measurement would be dependent on the speed of the computer.

That makes sense. Are there other cleaning methods than Etanol or Isopropanol
that does a significantly better job ..?

Not sure what you mean by "significantly better job". What ever method
you use, as long as it cleans it off, its suitable. Do you mean is there
a faster way?

If doing a small batch by hand, use a minimally abrasive sponge rated
for TeflonŽ cookware. As I recall, the commercial process uses a high
pressure solvent wash (but I stand to be corrected on that).
