'[BUY]: PICMASTER T-Probe'

Mark:

I've got one, but it's for the PIC-Master CE; it won't work with the
regular PIC-Master without an adapter.  The adapter used to be
available from Microchip; I have no idea if they still sell them.

If you can use the CE probe, let me know; I don't think I want to
sell it at this point, but I'd be happy to lend it to you for a while
if you pay shipping/insurance both ways.

>PAL webcam ?

Hi Mark,

you need to make the client state whether he wants a PAL format TV signal
or a digital stream of images that is roughly equivalent to PAL TV  (i.e.
50 fps and about 800x600 pixels at 10 bits resolution). Then try to
understand what digital format he wants ...

... therein lies the problem;  I'm starting to think he wants a PAL
Camcorder - or maybe a lawnmower or a new car?  <G>

(Someone please SAVE ME from these people who *want* but dunno what they

Hi everyone,

I was wondering if anyone knows about a single chip recorder and playback.
I looked in a lot of places to find the chip number and I only found
ISD1410.  However, I cant find a distributor for this chip. Please let me
know if their is any other recorders and playback chips or if their is a
distributor for the chip that I am looking for.  This chip is ultimately
going to be hooked up to the PIC.
Thanx for your help

Digikey has a whole series of ISD chips - ISD14xx/25xx/etc.
Jameco also carries some.

Go to ISD's web page, they have a lot of different variations of the ISD
chips.

http://www.isd.com/products/chipcorder/

There is also a link on that page to find out what distributors are in your
area

'[BUY]: A short piece of work for someone'
2001\02\08@112255 by Intellicorp001

Hi,

  My name is Wilson Logan. A few years ago I got a friend to help me build
a data logger based on the PIC 16C74A-04P. Unfortunately, in the final
throws of the project, through no fault of his own he was unable to complete
the thing.

  I've thought about finishing it myself but although I could write the
assembler, the electronics would defeat me.

  I've got 1) A circuit diagram 2) A board design 3) A parts list 4) The
assembler for the microcontroller 5) A delphi program to receive the data
from the logger 6) A prototype (minus the PIC Chip itself).

  As I understand it. The thing is up & running minus some work to get a
real time clock going with it.

  I'm a private individual with limited means but I've got a couple of
hundred pounds worth of a budget to get this finished.

  If anyones interested they can contact me via email at

  @spam@intellicorp001@spam@spam_OUTmch10.sbs.de


  I don't mind where in the world you are (I'm in Munich).

       Best Wishes,

              Wilson Logan.

I got hold of 6 x 745/JW and 6 x 745-I/SP just after Christmas I had
been waiting for also a year for them and finally managed to place an
order in mid November for them with a UK supplier.

I did have 1 engineering sample in September which was a 745-I/JW ES
00250A5 the 6 I got a few weeks ago were 745-/JW 00430B7

From what I can see on the ARROW web site http://www.arrow.com this particular IC
is reserve for large manufacturers. Arrow a fairly but there is quite a
variety of prices.

I chose Arrow as they are well represented around the world. I purchaced the
MAX1676 DC-DC converter Eval Kit from them and found it cheaper than buying
direct from Maxim. I also found that I can buy small quantities for research
and have good prices for quantities

Arrow seem to distribute many components.

Hobbyists probably don't use Maxim parts - they're just too durn
expensive - I always wonder who can afford to buy their stuff.

D-K seems to be the major hobbyist supplier of Maxim parts, but there
must be other guys - maybe Allied, Arrow, Future.

'[BUY]: 3M ZIP DIP or Similar'
2001\02\19@103201 by Matthew Twomey

I am wondering if anyone knows of a good online vendor where I can
purchase some different kinds of ZIF sockets. I see that 3M makes some
very nice ZIF sockets for DIPs (their ZIP DIP series). I can't even find a
place to order these online. Any help would be appreciated.

Sven, if worst comes to worst, and you still must fix this equipment,
you may be able to get by with cutting out the chips and soldering on
some discrete NPN inverter circuits. That is really all RTL was.
Somewhere I have an old textbook showing nominal resistor values.

Milton;

I have been working on some modernization efforts for the nuclear industry.  They have a number of designs which used this old logic.  The logic, if I
recognize the numbers, are MHTL logic, which is a high threshold logic version of DTL logic made by Motorola.  I would be wary of Dan's suggestion for
replacing with transistor logic, Dan assumed RTL, and in reality they are a bit more than that.  He meant well.  The best bet is to use a comparator around
7.5V (this is fixed regardless of supply) and then deal with the logic levels.  Outputs are either an active transistor output in a peculiar buffer
arrangement, or a passive pullup with active pulldown.   Not a clip out solder in solution.  I know that the nuclear industry went absolutely to the end of
the earth to find these parts, which have been out of production for probably 25 years.

Wish the news was better.  Sorry.

If you want enough $$$+ worth to make it worthwhile for them, just contact
a gray
market dealer, there are still plenty of these old chips floating around.
Be sure
to specify the suffix (L or P).

According to the textbooks [if one can believe them], "all" of the
old RTL, DTL, and HTL gates are fairly straightforward NPN circuits.

So, if unable to find these gates/chips anywhere, and if fixing
the equipment as opposed to trashing it is the major consideration,
then it would seem that clip out solder in may be the only possible
course of action. It cannot be all that difficult to try, assuming
only one or a few gates are blown - either works or doesn't work.

Unsolder the old chips, solder wirewrap headers into the holes, build
a new gate on fiber board [kind with plated-thru holes], and solder to
the WW legs.

[of course, this thing probably wouldn't meet FDA approval].

No, this is what "has been" running our nuclear plants.

[probably also the air traffic controls, IRS, B-52 bombers,
10,000 nuclear tipped missiles, most of the navy, and the SAC

Hi Dan,

I wasn't clear. What I meant by "this" was little
hacked discrete replacements for old ICs. IIRC, someone
said that he was upgrading nuclear power plant
electronics and had to deal with these old ICs by
replacing them with equivalent circuits.

No.  Original poster was asking for replacements for RTL
to repair X-ray machines.

Second poster said to swap discrete transistors for RTL.

Third poster said he'd been working with the nuclear industry
on RTL and other old logic families and warned _against_ using
discretes as replacement parts.  He said the nuclear industry
has bought up all the old replacement parts to keep their own
equipment running with the proper replacements.

                                               Lee Jones

P.S. Last I heard, air traffic control system was still
    on IBM 9020s, circa IBM 360 level of technology.

I know that you wanted someplace closer than the US but...

Rochester Electronics( http://www.rocelec.com/ ) specializes in parts
like this. They even buy old masks to keep producing some popular (but
old) parts.

I did a search on their site and found the MC660L for about $11 US. They
do not show a MC672.

Thanks, yes they do. I generally found in the past that Farnell
were pretty much on a par with RS so didn't look (my last
catalogue got biffed out some time ago). The price they
gave me was Aus$21.04, which by the time you add sales
tax, freight and conversion comes to NZ$30.43 each. Ugh.
To go without them though will mean a lot of extra coding,
more than $30 worth for sure (just trying to cheer meself up).
Might hang out for a day or two for a better offer

'[BUY]: Low cost PCB etc. & programming design serv'
2001\03\22@042354 by Spehro Pefhany

Hi, We've gotten backed up with projects, and there are a few
personal ones that have been sitting in file folders for months.

Anyone interested in a SMALL amount of money for taking these
from schematic to Orcad PCB MAX files (including creating
footprints)? Timing is flexible, all are "speculative"
projects.

Most of my stuff is mixed signal 1-4 layers sometimes with
high voltage/current. Typically 30-150 components with
10 requiring special locations, in board sets of 1-3 boards
per design.

There might also be some PC Win32 programming (to interface with
PICs etc.) and some ethernet-TCP/IP micro-based programming.

If you are interested, pls. let me know your rates and what
similar work you've done as well as availability.

Best regards,

I purchased one from Farnell about a months ago. I had to wait
3 weeks to get it. Perhaps they got more than 1 in!!
The description on their web site is confused. I hope they have
fixed by now. I had to have a little talk with them.
Zatek (Pic distributor in Australia) were kind
enough to give me a sample so that I could finish off a project.

The following is right out of their web site order confirmation,
except that the description is incorrect and the part number is
infact for the 18 pin plastic DIP which is what I wanted.
The price is of course 3 times what one should pay.

(Farnell Part 2)    3154786
(Description 2) IC-SM-8-BIT MCU
(Quantity 2)      1
(Price 2)    $    15.9400$

Ah, that sort of clears it up. Future Electronics think they can get
a tube @ US$3 each (US$100 min order so probably 2 tubes),
but like Arrow they're out of stock too (4 week lead time). The
freight on that deal would be US$29, ouch. US$179 (2 x 25 x 3
+ 29 = NZ$436) far exceeds what I want to spend just to get the
1/2 dozen I need for now. I've had an off-list offer at a much better
price and quantity

Hello
My company is looking for 6' power cables with a regulated 12V wall wart 600-800 mA -- the connection doesn't matter as we're going to snip it.  We need a couple hundred. I am having a surprisingly difficult time finding a supplier -- the density of products which ship with said connector makes search engines all but useless.  
Can anyone recommend a distributor or manufacturer?

Barnaby,

Check with Radio Shack.  They have a 12V/1000Ma Power Adaptor.  I
can't remember the cost for sure now, but I believe it's around
$15.00USD or so.  RS part number 273-1776.  It has a connector on
it that is a two pin side by side affair that is meant to receive a
target device specific connector.  But if you will be cutting off
the connector anyway, it doesn't matter.   Hope this helps you out.

                                           Regards,

                                             Jim

'[BUY]: Looking for PIC 16/18 firmware developer'
2001\05\22@185025 by ron

Hi fellow PICLISTERS -- I'm looking for an experienced firmware
developer familiar with PIC C to help us out.

My name is Ron Wilder and I've been on the list for many months now as
"Wilder Engineering" and have really enjoyed reading the messages "in
the background".  While doing so, I have started a small, new company
that is developing an exciting set of products and services which is
based significantly around PICs.

A little history
Our company,  Agile Access Control, Inc. is searching for someone who
might be interested in doing some custom firmware for our company.  We
are developing a product that melds web and touch-tone telephone
scheduling with hardware to control the check-out and return of physical
keys. My previous company (http://www.wilderengineering.com/ed) develops
touch-tone and computer-based reservation systems for flying clubs,
car-sharing groups and even the FAA (at the Air Traffic Control Command
Center --- you should see this place!) and it just seemed like a natural
progression to develop a product to hand out the keys that were
reserved.

Soooo... I convinced the program manager that I worked with at the FAA
command center to quit his job (this was tough, considering that he got
to see and play with all of the neat toys at the FAA), be the company
CEO and work with me to develop this product. Since then, we've been
putting a team of people in place (all from their homes at the present
time) who specialize in areas including web developer, firmware
engineer, sales, marketing, accounting, mechanical engineering, and, of
course, myself as CTO (Chief Technical Officer) and jack of all trades
(hardware, firmware design, touch-tone software design, etc.). We
formally incorporated in California last September and we have already
demonstrated our initial prototype system at a trade show in San
Francisco a couple of months ago.  The customers are already lining up.
We have interest from the commercial sector, universities, state
government, and a large military
customer.  Now all we have to do is deliver the product!  Heard this one
before????  Me too!

As is predictable, the firmware has taken much longer than anticipated,
primarily due to our firmware engineer's requirement that he only work
on weekends...  Anyway... we now realize that we need to find someone
who can commit to reasonable schedules and will do whatever it takes to
make commitments that are made.  We will reward this individual with
stock and $$$.  We also have a bonus plan based on sales as a teaser.

Interested???  Additional details follow.

Agile Access Control
Incorporated Sept. 18th 2000.  Privately funded C Corporation based in
Campbell, CA. (Silicon Valley).  We do have about 10 people at the
present time working throughout the country from their homes.  We have
customers waiting for us to release our first product and they are very
excited about how it will really help them revolutionize their business.
Check out our web site at: http://www.agileaccesscontrol.com.

Hardware
We have a neat product and uses a lot of PIC controllers that talk via
the i2c bus.  Our product includes neat hardware including:  proximity
card/fob reader, credit card reader, RF transceiver (short range), LCD,
tiny modem, keyboard, serial I/O, motors, iButtons, embedded web server,
thermal printer... to name a few.


What we need
Ideally, we would like to find an experienced, self-starter who can help
and perhaps lead the firmware effort on a more dedicated basis.  You
would need to bring PIC C experience with you as our schedules wouldn't
allow us to train you.  You would also need to have a track record
developing embedded systems (and have a verifiable resume that supports
this) and have experience writing code for specialized hardware such as
that mentioned above.  I'm not expecting that anyone have experience
with all of the above hardware, just enough of it to convince me that
you have the required experience that would allow you to easily develop
code to get it up and running.

We are on a "fast track" (surprise, surprise) but at the present time
and for the foreseeable future, we all get to work at home and own a
piece of the company.  You'd be working directly with me and possibly
another firmware engineer who has developed our demonstration firmware,
to date.

Myself (You'll be working directly with me)
I'm a degreed (U.C. Berkeley) and licensed (in California) Electrical
Engineer with a strong hobbyist background. I've been an amateur radio
operator (K6RON) for thirty years (although fairly inactive lately) and
have designed both hardware, firmware and software for over 25 years.
I'm a private pilot, SCUBA diver and nerd to some (you should see my
computer room).  I'm also a MicroChip Consultant.

I've enjoyed designing the hardware and some of the test firmware, but
it has come time to try to find another person to help in the firmware
end of things.

Your Location
Ideally, you are located in either Northern California or near Chantilly
Virginia.  This would allow easier face-to-face meetings with us. Of
course, joy rides in my 4-seater Mooney airplane will be more frequent
the closer you are to San Jose!

Still Interested???
Let's talk!

Please send email directly to me at:

or call me at:

I+need+someon

Hi there,

We found your site by a quick search.

We are a small distributor (come manufacturer) of CCTV equipment.

We are searching for a company or an individual to do some pic programming
for us at a reasonable cost. Are you interested?

Overview.
We require a pic that is fairly small in size and reasonably low cost. The
pic will do nothing special and is basically a timer with 3 outputs and 1
trigger input. One timing period needs to be adjustable using simple
external components such as a variable resistor.
Operating voltage = 5V.

We need the following to happen;

1 -A pic to start a timing routine on a negative input.
2- A pic output pin, say "A" to go low for 1 second after the input.
3- Start a timer (0-5mins) that inhibits another input causing "A" to go low
again during this timed period.
4- At the end of the timed period cause a second pin to go low (say pin "B")
again for 1 second.
5- Whilst ever the timed period is running a third pin "C" goes hi-low at a
rate of about 2hz.
6- After the timed period the input now accepts a negative trigger to start
the routine again.

Notes -
The timed period needs to be adjusted by a small variable resistor or
similar from say 0-5 minutes. None of the timing is absolutely critical but
+/- 10% would be great.


What do you think?

Can you please let us know as we are keen to find someone to help us out
with this project. If you have any ideas about costs, please indicate these
as it will be useful.

Many thanks,

Paul Goodwin.

Go to any of the manufacturers that make switching regulators (such as
http://www.linear-tech.com/ )  The app notes and data sheets will have
tons of designs, and many have programs for making custom circuits with
a few inputs.  National has a web based switcher design program which,
while limited, is very nice.

mfg or vendor has suitable units from which to choose.

I myself have had some experience with HAKKO.  Another guy here has
experience with PACE.  And we have both PACE and HAKKO equipment in
the lab.

So, the questions are ....

1.  Which manufacutrer do each of you prefer? ..and..

2.  Which unit from that manufacturer do you each prefer? ..and..

3.  What other manufacturers are there out there other than the
    two I have mentioned? ..and last but not least..

4.  What is the price range?

It should be capable of handling components down to at least 0402,
and preferably smaller.  It also should have some sort of XYZ type
adjustment (Such as a micromanipulator) for precise component
placement.  A means for dispensing solder paste and a preheater
would also be beneficial.

At this point in time cost is not an issue.  But the unit will be
used mostly in our engineering lab and not in a production
environment.  So production capacity is not necessarily needed.

Anyway, I'd appreciate hearing your thoughts and suggestions.

Email me offline if you wish to save list BW.

'[BUY]: WTB Microchip PICPRO II programmer'
2001\07\23@185206 by Mednick, Cary

I am looking to buy a PICPRO II programmer with a 16C5X Dip Module. We use a
software application that was written to directly interface with this
particular unit and newer units do not respond correctly.

Does anyone know where to look for one of these? Any help that you can
provide would be appreciated.

'[BUY]: USB Analyzer'
2001\08\16@224427 by Eric Johnson

Hi All,
       In trying to get my 16c74 to use the National 9603 usb interface chip, I
have gotten to the point where I need to see what is going on at the USB
signal level.  However, the prices for usb analyzers are beyond what I can
afford.  Does anyone have a used analyzer to sell or rent?  I don't need
more than the basic features.  The older version of the USB protocol (I
don't need high speed) will do what I need.

Of course, I assume your $199 quote is in USD, the person was talking about
prices in CDN.

I'm looking for a 120VAC 60Hz to 650VAC transformer, with as high an amperage as possible up to 2.5 amps output, 150mA at the bare minimum.  This will be used in a power supply for a pulsed Nd:YAG laser.  I would prefer a new transformer as opposed to an old one from vacuum tube electronics.

Thanks,

Try this company:

     Nyco Transformer Company (PA) (610) 327-4106



I had them do a 3kv 1amp transformer for a university project... cost a
couple hundred dollars though.

Not sure they are still in business though... it was quite a few years ago.

No!! 120V into a 24V winding will probably give you less than 200V out, and
will definitely give you SMOKE.

You can go lower than rated voltage, but not higher.

Do you really need AC out? I would suggest getting a suitable isolation
transformer, say 3KVA, like you would use for power tools, and then have a
voltage multiplier rectifier arrangement on the output.

I've never liked the idea of overrating a transformer
like that.  Although it can be done, if I'm going to
spend a few hundred dollars on this device, I want to
do it right.  If at all possible I don't want to have
to modify any transformers either, or have to use any
type of multipliers.  I'm hoping someone on here can
lead me to a source of transformers for what I am
looking for.

But thanks for your reply, I appreciate you trying.

Another option may be to check people who do advertising signs for
transformers that drive neon signs. I do not know what the voltages involved
actually are, but it may be worth a try.

Another loop may be to try ballast units for mercury vapour lamps. Again I
do not know what the strike/sustain voltages are, but may be in the
ballcourt for what you want.
