I am a process engineer in a PCB factory.

I face a problem in printing solder mask. There are some pin holes on
the solder mask, appear on both copper and laminate. It made some
masked area is too thin to protect the circuit.
Supplier said it is caused by broken of gas bubble while printing,
but I am sure it is not! I observe the board after printing:
Bubbles break in few minutes and ink leveled. Few more minutes later,
pin hole come out just as de-wetting.
I had cleaned the pre-treatment and printing equipment, and also
change to other versions ink (same supplier). No good result give out.
Lower the ink viscosity by thinner also give improvement.

Some classmates tell me it maybe caused by too much of anti-foam agent
in the solder mask ink to cause de-wetting. I cannot prove it.

Any body can tell me how can I solve this problem?

Greetings,

I recently had a PCB prototype made and I thought I would share the
experience, so that others might avoid the same mistakes.

I shopped around for a while and was initially discouraged by the setup fees
boardhouses charge, which is typically $40 or more. I finally found a place
that charged a flat $21 fee per board (single sided 100x160mm FR-4, 1.5mm,
1oz copper, with solder mask and component mark, $2.60 extra if over 500
holes). They are Olimex, in Bulgaria (http://www.olimex.com/pcb.html). No
problem, I thought, US post office only changes about $5 for a letter to
Bulgaria, so it ought to be about the same coming back.

I used CadSofts Eagle software to do my board design, which ended up being
about 1.5 x 2 cm. I duplicated the board so that I had 42 copies for output
and sent it off (actually Olimex duplicated the design for me, since the
free version of Eagle limits you to the board dimensions).

After the board was finished, they emailed me and informed me that since the
text I had placed in my component mark to indicate which way was up (so they
would not mistakenly mirror it) was less than 12mils and had not come out,
so they had mistakenly mirrored it (apparently they did not notice that 'C1'
and 'U1' labels, which are visible, were mirrored too). No big deal, there
are only 3 parts on the board anyway, it just won't have a version number
and my email address.

In the same email they inform me that TNT (the local postal service??)
refused to 'ship with freight collect to US ', so they had sent it UPS. A
few days later UPS shows up and wants $75.25 before they will give me the
package (which is a very large manila envelope filled with bubble wrap
around this little fiberglass board).
Fortunately I happened to have $75 I could pay them with, and was able to
get the package.

Apparently the $75 was customs fees for getting this thing into the US.
This is truly an insane amount to charge for bringing 40 grams of fiberglass
costing $20 into the country. Anyone know if simply putting it in an
envelope with no packing material would avoid the fees?

On examining the board, I found that the copper and solder mask was perfect.
The only problem is that the component mark for the single IC (which was
centered on the board and so was still in the right place) was on top of the
solder pads.

The component mark for the parts in Eagles libraries includes little lines
where the pins will be, and so the pads all get covered in white component
mark ink (whatever that is). Fortunately, since the pads are tinned, it is
easy to scrape off, but cleaning 336 tiny SMD pads was not how I wanted to
spend my time.

I've posted a question to the Eagle forum to see if I made a mistake on the
component mark, but I don't see how I could have gotten around it without
modifying the mark itself.

So, I've spent $100 for a single 100x160 board. I'm fortunate that since it
contains multiple copies of my PCB the cost is distributed down to about $2
each, or I'd never make my money back (they are part of a kit I am selling).
Over all I am satisfied with the board, although it cost me 5 times what I
was expecting to pay. If you can get around the customs fees in the US (its
not a problem if you are in Europe), and you make sure your stuff is clearly
marked so it doesn't get mirrored, Olimex really is a bargain, I give 'em a
thumbs up, hooray for no setup fees!

The next step is to cut the little guys apart and try my hand at soldering
SSOP chips with a regular iron. :)

Belfort Instrument Company (dba Belfort Instruments, DigiWx AWOS,
Gamma Scientific, UDT Instruments, Advanced Retro, RoadVista, KR
Acquisition Corporation, Utilipoint International, QuickStrategy &
Scientech) is once again trumpeting that they provided wind sensors to
the Wright Brothers.


DO NOT BELIEVE THIS COMPANY BUNK (aka BULL-SHIT)


BELFORT DIDN'T SUPPLY AN FUCKING THING TO THE WRIGHT BROTHERS (there
are NO historical records or archives to back this up)


BELFORT MANAGERS ARE SKILLED AND MANIPULATIVE FUCKING LIARS


BELFORT AIMS TO PROFIT BY LYING, DENYING AND CONCEALING


BELFORT INSTRUMENTS SELLS TO TERRORISTS NATIONS (ie. Pakistan)


Belfort Instruments Digiwx has t-shirts emblazoned with the phrase:
"The Wright Brothers Relied on Us"


American history seems to tell a very different story!


There is a Belfort Instruments company press release at:
http://www.prweb.com/releases/2003/6/prweb67805.php


It reads: "The Wright Brothers monitored these
(i.e. Belfort's) instruments as they prepared for
their famous flight on December 17th, 1903."


THIS IS COMPLETE BULL SHIT (Bruce R. Robinson style)


Here is what the Wright Brothers really wrote on December 17, 1903:


"We had a 'Richard' hand anemometer with which we measured the
velocity of the wind. Measurements made just before starting the first
flight showed velocities of 11 to 12 meters per second, or 24 to 27
miles per hour. Measurements made just before the last flight gave
between 9 and 10 meters per second. One made just after showed a
little over 8 meters."


And then there is that indisputable picture of:
WILBUR WRIGHT USING A RICHARD'S ANEMOMETER (picture)
http://www.google.com/search?q=richard+anemometer+orville+and+wilbur
http://wings.avkids.com/Book/Wright/history1_19012.html


Utilipoint International CEO Bruce R. Robinson is trying to re-write
history to include mention of Belfort and/or Friez. This is a shame
and a sham!


Buy anything except Belfort Instrument Digiwx AWOS from Bruce Richard
Robinson and company.

Ebosswatch.com rating with Belfort Instrument Company
http://www.ebosswatch.com/Reviews/Mark-W.-Decker/1412568293
Rated by his peers as "Unfavorable" in 7 different job categories

And now Belfort Instrument Company (dba DigiWx AWOS, Gamma
Scientific, UDT Instruments, Advanced Retro, RoadVista, KR
Acquisition Corporation) finds itself in United States Bankruptcy
Court as evidenced by:
http://www.amrcaseinfo.com/pdflib/1631_15463.pdf

Belfort Instrument Company financials are so BAD that CEO Bruce R.
Robinson has his primary residence in a trust as noted at:
http://www.city-data.com/bernalillo-county/P/Paa-Ko-Drive-2.html

You might ask "Why would someone put their home in a Trust?" at:
http://belfort-instrument-company.pissedconsumer.com/belfort-instrument

"Belfort's owners have "valuables" (like their homes) held in a trust
to prevent creditors (in this case, the bank that lent Belfort
Instrument Company all that money) from seizing their personal
home(s) when Belfort can't pay back the business loans. In the case
of Belfort Instrument Company, this was a smart move (some might
consider this a sneaky move also) because I pulled Belfort's credit
reports from the 3 main credit bureaus and Belfort is currently
delinquent and "past due" with several creditors by more than 90
days and in some cases 120 days. This means the money isn't coming
in fast enough from sales to pay for the company's debts. I even
found notes that some of Belfort's creditors are on a "cash only
basis" meaning Belfort needs to cough up money for goods and services
(raw materials) before another company will even sell them those goods
and services. This is NOT a pretty picture. This has been going on
for years. If you would be inclined to buy finished product from
Belfort, you may find a company which doesn't stand behind that
product because they went out of business. Info from Dun & Bradstreet
indicates turnover in this very small privately-held company at the
managerial and executive level so people's heads are probably
rolling there and it is likely only a matter of time before this
business is no more!

So who was driving these companies into the hole...... because there

Wanker Mark W. Decker Shatters World Masturbation Record
http://mark.w.decker.mediafetcher.com/news/top_stories/worldrecord.php

ATTENTION: Mark Wilson Decker is apparently posing as a photographer
based upon his Workface, LinkedIn, Posterous, Twitter About.me,
BigSight, Ziki, tBlog and Wordpress profiles --- just goes to show
you how sneaky AND creepy he really is! He's an unemployed fired POS!

WHAT WOULD MARK W. DECKER BE TRYING TO HIDE???

Well, have a LOOK at this:
Two federal cases that specifically mention Mark W. Decker:
U.S. Department of Labor Case # 2006-SOX-57
U.S. Department of Labor Case # 2006-SOX-81

According to:
http://www.mombu.com/aviation/civil-aviation/t-faa-dol-osha-fdic-doj-
investigating-belfort-instrument-digiwx-awos-10453477.html

Mark Wilson Decker was investigated for:

"FAA is investigating Belfort Instrument President Mark W. Decker and
Digiwx AWOS Tech M. Tylor Burton for bribing federal FAA officials."
"DOL is investigating Belfort Instrument President Mark W. Decker
for retaliating after suing a former employee who ratted Decker
Pecker out under a federal whistleblower protection program."
Did Bruce R. Robinson, Nicholas C. Kaufman, Debra S. Alascio Lange,
Ralph F. Petragnani and M. Tylor Burton aid in this conspiracy?

And there is MORE:
All the info contained herein has been published in some form
since at least 2005. Mark Wilson Decker gave up any legal right
(he may now be asserting) a long time ago that this info is
injurious to him or his family since the statute of limitations
to bring a libel lawsuit is 1 year in each of the 50 U.S. states.

Once aginz, she jerks it hard withz both handz. Again, I'z begin to

Mark W. Decker has a boat named Spoony:
http://www.boatinfoworld.com/registration.asp?vn=96438

What do you think the chances are that he has already
"spooned" and felt-up all three of his daughters (Audrey,
Hannah and Libby Decker) aboard his boat with his "vessel"
which he has a propensity to play with.... even in public!
Let's see if this causes Mark Kacucha some legal trouble:

Belfort President Mark W. Decker (U.S. Naval Academy alumnus), let
me tell you about this lowlife. Starts the workday between 9-10AM
by checking work and personal email. Come 11-11:30AM, he's ready
to go to the local gym to work out. Gets back in the office around
1PM and only then decides to take a lunch break as if the gym work-
out didn't count for a lunch break. By 1:30PM, he's checking work and
personal email and maybe making a few entires in his family diary
which he keeps at work on the company hard drive. Come 3-4PM, he's
getting anxious and is looking to wrap up his workday so he can go
home and coach soccer league for one of his three daughters.
Needless to say, all thru-out his "playful" workday, one gets to
see all his dirty nasty habits including:

1) scratching his balls,
2) stroking his c o c k,
3) farting (and then asking someone else if they farted),
4) belching,
5) biting his fingernails,
6) picking his nose (and eating the choice boogies),
7) scratching his ass,
8) picking at his toenails
9) coughing (he has a chronic productive cough... yuck)
10) he has kidney stones (and urinates with pain)

Now keep in mind that this is a US Naval Academy graduate (Class of
1979) who's motto is "don't do as I do" but "do as I say!" Makes
complete sense because he superiors in the U.S. Navy recognized his
lack of leadership very early on. That's why Lt. Decker didn't last
in the U.S. Navy and decided to enter the corporate world where he
could use his skills of conniving, lying, denying, concealing,
deceiving, and making things up!

Let's get this straight, he been with at least three different
companies over the past dozen years, all where he had a hand in
running them into the ground. Doesn't a midshipman know how to steer
a boat to prevent it from running into the ground? He's been with:

1) Unc, Inc.
2) Mentor Technologies
3) Belfort Instruments

And now there appears to be evidence that he either resigned or
was fired from Belfort Instrument Company for "poor performance."
Seems like he spent four years trying to sell DigiWx and DigiWx AWOS
and was a miserable failure at all of it while dragging down the
finances for the rest of the Belfort company. It's easy to conclude
that Mark W. Decker is "all that and a bag of chips" along with
some "s h i t" salza on the side!

How many freakin passes does this lowlife (who was born with a silver
spoon in his mouth) get? What kind of role m o d e l is he for his
three daughters Audrey, Hanna, and Libby Decker? And how about his
wife Jennifer Racey who decided to keep her maiden name (maybe
because she knew about the lowlife she married).

Why do we have lowlifes like Mark W. Decker around? This guy thinks
he the best thing since sliced bread. He doesn't think his s h i t
stinks and he doesn't think too highly of woman in general either.
Wonder how he'll explain that one to his three daughters one day?
- show quoted text -
And then we have this:
Hannah, Audrey & Libby Decker (daughters) were found dead in a
second family home owned by Ralph P. Decker, Mary Ann Decker, Mark
W. Decker and Jennifer L. Racey according to land records available
from the Maryland State Department of Assessments and Taxation. No
immediate cause of d e a t h was available. The second family home
is located at: 11 Silverwood Circle SILVERWOOD Unit 3, Building 11,
SC 3, Annapolis, MD 21403.

No explanation was available about how Hannah, Audrey & Libby Decker
ended up in this second family home versus the other family home at
289 Long Point Road, Crownsville, MD 21032-1853 which is noted as
being the family's primary residence according to land records
available from the Maryland State Department of Assessments and
Taxation.

And then this:

Lange), Jowl, Belly & Ass Ralph F. Petragnani, and the other THREE
STOOGES: William C. Gordon, Bruce R. Robinson and Nicholas C.
Kaufman.

Lastly, we have this:
Belfort Instruments Digiwx has t-shirts emblazoned with the phrase:
"The Wright Brothers Relied on Us"

American history seems to tell a very different story!

There is a press release with President Mark W. Decker
name on it as the contact at:
http://www.prweb.com/releases/2003/6/prweb67805.php

Mr. Decker says "The Wright Brothers monitored these
(i.e. Belfort's) instruments as they prepared for
their famous flight on December 17th, 1903."

THIS IS COMPLETE BULL-SHIT (Mark W. Decker style)

Here is what the Wright Brothers really wrote
on December 17, 1903:

"We had a 'Richard' hand anemometer with which we
measured the velocity of the wind. Measurements made
just before starting the first flight showed velocities
of 11 to 12 meters per second, or 24 to 27 miles per
hour. Measurements made just before the last flight
gave between 9 and 10 meters per second. One made just
after showed a little over 8 meters."

And then there is that indisputable picture of:
WILBUR WRIGHT USING A RICHARD'S ANEMOMETER (picture)
http://wings.avkids.com/Book/Wright/history1_19012.html

Belfort Instrument Company President Mark W. Decker
is trying to re-write history to include mention of
Belfort and/or Friez. This is a shame and a sham!
Buy anything except Belfort Instrument Digiwx AWOS
from Bruce R. Robinson and company.

MARK WILSON DECKER (Class of 1979 U.S. Naval Academy)
http://www.e-yearbook.com/yearbooks/
United_States_Naval_Academy_Lucky_Bag_Yearbook/
1979/Page_167.html

Mark came all the way across town to attend Canoe U. Plebe year he
became a news column regular from a starting position on the varsity
soccer team and co- captain of the plebe lax team. Youngster year
brought endless hours of study and a permanent nickname, " Max."
He strove to max all he did and was involved in everything from hang
gliding to " 4 pts. " and stars and strips. His home became the
refuge for many youngster autos and drunk classmates, none the
less the welcome mat was always out, and the hospitality was
deeply appreciated. Second class year saw the dawning of the
star fleet command of which Max was the CO. Even though Mark
had female pussy connections in nearly every college in Maryland
and Virginia, his 20-10 was primarily focused on the Ivy Leagues.
Whether commanding a squadron or managing a corporation,
you can bet Max will maximize and run it into the ground.

I saw where Mark W. Decker is now working at Belfort Instrumentation
as I always wonder where he went after skipping out of Dodge City
just barely when he left Mentor Technologies. If he hadn't left
in 2001, Decker would have been shown the exit after his dismal
performance at Mentor. The thing I will always remember about Decker
was his passion for playing pocket pool, the kind one plays when
they have something nasty growing in their crotch out of control. I
mean get some Desenex or something for that jungle rot. He was
absolutely icky just watching him work his hands in his pants pocket
as he attempted to reach his private parts in search of a much
needed scratch. Several coworkers wondered exactly why he scratched
his crotch in public for everyone to see and notice. I guess he
figured that he could be a Baltimore Oriole Cal Ripkin on the
baseball diamond and nobody would notice, well many people did
notice and found it disgusting and repulsive to say the least.
I always wonder what his wife must have growing in her crotch as a
result of him passing along his germs and god knows what else to
her. Anybody at Belfort Instrumetnation seen Decker digging at his
pecker in public? I would bet he still is!

Belfort Instruments suing fired worker Mark W. Decker

A Baltimore manufacturer of weather instruments is suing a fired
employee it claims is on an anonymous Internet rampage. Belfort
Instrument says Mark W. Decker has been harassing current Belfort
employees via e-mail, calling the company's customers and partners
alleging unethical business practices, and posting trade secrets on
the Internet. Defendant Decker has an alarming history of engaging
in such 'anonymous' Internet attacks against those who he believes
may have slighted him (including past employers), and, absent a TRO,
will continue his historical pattern of making outrageous & harmful
attacks against the material business interests of Belfort
Instrument, reads Belfort's complaint, filed earlier this month in
Baltimore County Circuit Court. Belfort, which obtained a temporary
restraining order against Decker on Nov. 15, is suing him for
misappropriating trade secrets, breach of contract, defamation and
tortious interference with contractual relations. The company is
seeking $1M. After consulting with his client, Belfort attorney Doug
W. Desmarais declined to speak about the case. My client's position
is that this is a dispute that they have chosen to resolve through
legal channels, and they're going to let it play out through legal
channels, Desmarais said. Decker could not be located for com-
ment; his phone number is unlisted and a reverse search of his
Annapolis, MD address produced no results. According to the
complaint, when Decker started working for Belfort in 2001, he
signed a contract promising that, if he left the company, for two
years afterward he would not say negative things about it; if he
did, he would face court action. He is also bound by the Maryland
Uniform Trade Secrets Act not to divulge privileged information,
Belfort says. Decker was fired on Oct. 20 of this year and then
started to harass his ex-girlfriend, still a Belfort employee, via
e- mail, the suit reads. He also allegedly emailed the company's
general mailbox anonymously, promising to fight back against
the company and drive it out of business. The company also
claims he called their customers and made untrue allegations.
Decker also used an Internet newsgroup to criticize the Belfort
product he had been in charge of marketing, the DigiWx AWOS digital
weather transmitter, calling it DigiSHIT, Belfort claims. He also
allegedly listed which of Belfort's customers were using DigiWx. The
motion does not state how Belfort knows that Decker is behind the
anonymous e-mails, phone calls and Internet postings, but a letter
from Desmarais to Decker warns that Belfort can easily trace the
communications to Decker. Belfort also claims that Decker has a
history of using pseudonyms to criticize whoever has offended [him]
on a particular day. Indeed, a search of Google's newsgroups shows
lots of chatter about Decker, including several posts purporting to
unmask him as the anonymous source of negative comments about
Baltimore.

Does anyone have anything good to say about Belfort's Digiwx AWOS?

Hi Adrian

I also try to find it to fix my sons boat.
Did you find one or a replacement.

Best regards
Goran
 
I am interested in just the TENMA 72-2040 meter. I either had mine stolen or I managed to lose it after 7 years of use. Please contact jjrjra16988816@gmail.com

Come on, the original post is from 2000. The guy either sold the stuff
long ago, or trashed it. He's certainly not reading this newsgroup after
all this time, especially when this newsgroup has never had much traffic.

And this isn't a buy and sell newsgroup. There are newsgroups for that
over there.

This is Annan old thread but I was going to throw away the cards I have and wonder if anybody is interested in them, since now PE is available on the net probable will be ok to scan them and give them away.
I noticed that most circuits are taken from the components datasheet a and some also have mistakes or non existing components

Managed to score one my self in decent condition. Looking at the back of the unot dont reveal mich but that nine pin connector is numberd internally. Pin 1-9 from back of unit starting on the left. 1 gnd 2 gnd 3 gnd 4 -10v 5 SW 6 +10v 7 -27v 8 FL 9 FL. From my little experience the FL is most likely for the VFD display and can range any where from 16 to 24 volts. And the -27 volts is possibly for the internal op amps. Getting a positive and a negative voltage for 10 volts shouldent be too hard. I will try some experiments my self and I can drop you some messages if youd like

Hi All, the August MIT Flea will be held this Sunday, August 19th.

The Harvard Wireless Club co-sponsors the Flea Market and it provides a sou
rce of funding for our club. It is also sponsored by the MIT Radio Society,
the MIT UHF Repeater Association, and the MIT Electronics Research Society
.. It is a good opportunity to meet some of the people over at MIT. Just go
the main gate, and announce to the folks at the gate that you are from the
Harvard Wireless Club and are there to work. There is a sign in sheet where
you will put down your name, callsign (W1AF) and time in/out. Usually memb
ers put in a few hours, whatever you decide you can do. Also, try to intro
duce yourself to Steve Finberg from MIT/W1XM, who "runs the show". Before o
r after you "work", be sure to spend some time to browse around, there are
always some interesting things there (only technical/scientific items gener
ally allowed).
It is held at the MIT garage at Albany and Main Street. Lately, it is based
on the 2nd floor.
Anyone with a Harvard or MIT ID gets a dollar off admission. In addition, H
arvard and MIT students are admitted free of charge (with school ID).

People are needed as early as 5:30 AM, and as late as noon- 1 PM. Last mont
h we had a shortage of people at the end, at 2 PM. So, whatever time may be
convenient for you, the club would appreciate any time that you could put
in at the Flea.

It is usually held on the third Sunday of every month until October. This y
ear's other remaining date are: 8/19, 9/16, 10/21.
Questions? w1af.harvard.edu

Thanks! 73 -Bill Collins W1PL

Having not touched any of this kind of stuff for years I'm looking to
power a small TTL test circuit which I intend to built on a breadboard.
I wondered if I could run it off USB power. In other words, is it
feasible to power a TTL cct via a USB lead and USB socket?

I found a "USB Mini B Breakout Board"

http://www.hobbytronics.co.uk/cables-connectors/usb-connectors/usb-minib-breakout

but I'm not sure that the PCB bit of it is necessary and, besides, it's
only rated for 100mA (which may be enough but I can't be sure at this
stage). If not USB, I guess I should go for a wall wart and a 7805.

So the question is whether there's a good way to power a circuit via
USB, or whether you think I should go down the wall-wart or some other
route.

Any suggestions?

I use the USB connector on my projects now even if they have no
connection to a PC. It gives the choice of a PC/Laptop or one of the
many cheap USB wall wart chargers or a car charger. The USB connector
is almost a standard but for home use the breakout board is convenient
as the holes are on 0.1" pictch so you can fit a header to plug it in
to a protoboard etc.

That's good. If USB power is stable enough (and, if not, I guess I could
add smoothing) then it seems the most convenient option, what with
sources including mains, computer, car battery, portable power pack etc.

As for the connectors, which do you use. I've seen a USB-B receptacle
which might do

https://uk.farnell.com/amp-te-connectivity/1734517-1/usb-connector-2-0-type-b-rcpt/dp/2778492?st=usb%20pcb


There's currently a better shot of the pins of a similar socket at

https://www.ebay.co.uk/itm/K1X4-10-Pcs-USB-Female-Type-B-Port-4-Pin-Right-Angle-PCB-DIP-Jack-Socket-V7S1/302801941235

Is that the connector you use or do you get enough current through a
Mini-B or Micro-B or something else?

Incidentally, there's currently a type-A socket at

https://www.ebay.co.uk/itm/3pcs-USB-surface-PCB-mount-socket-Female-Type-A-connector-right-angle-ref-674-/283186649635

and its pins look like they might be more conveniently laid out /if/
they have 0.1" spacing. Can you see any reason not to use a type-A
connector on a device? Devices are supposed to use type-B.

Might be more difficult to find a suitable cable.
I have used a type B similar to the one you mentioned but horizontal
mounting. The 4 pins squeezed into a 0.1 pitch veroboard but the two
mouting holes had to be enlarged. Have also used the easier method
with the mini breakout and on one unit I just have a fixed cable with
type A at the end for power.

Whether such a piece of kit would be generally useful or not, such an
analyser wouldn't help in this specific case as it could not be used to
check the above decoder without also using a test program to cycle
through the inputs. The decoder is not socketed so I guess all I can do
is unsolder the chip and test the 16 permutations of its inputs on a
breadboard. If I'm wrong and there is a better approach please say!

I have a piece of old kit (Fluke Trendar 200 IC Testclip) that we were
issued with when TTL was mainstream. It has a 16 pin clip to attach
to the suspect DUT and a 16 pin socket. A number of special socket
can be plugged in to the one on the unit. Each special can have long
or short pins - long pins connect to the input of the DUT short pins
only connect to the exclusive OR gates which drive the LEDs. A good
IC is placed in the socket and the leds indicate a difference between
the good and DUT outputs. There is also a pulse stretcher which can be
switched to any pin.

Some info on google and at least one on ebay:-
