I. Novice/Beginner

[these are somewhat in order of most to semi recommended]

(From Michael Covington)

THE ART OF ELECTRONICS, Second Edition, by Horowitz and Hill. It costs about

$60 and will be the best $60 you ever spent (at least on electronics). Take

the opening couple of chapters slowly and carefully. If it's too advanced, read

some of the Radio Shack beginners' booklets first. (see below)

The above book ALSO has a students lab book of experiments. If you can do

most of them, consider yourself to be doing well.

(From Thomas M. Nathe)

Personally, I'd recommend the little booklets written by Forrest Mims. Just

about any Radio Shack should have them for a couple of bucks each. They are

easy to understand and don't to much to build (if you don't buy the parts

from RS). Mims has also written a couple of project books also, Snoop around

a good bookstore and they should have one around.

The Encyclopedia of Electronic Circuits (which I have) is more suited more an

advanced hobbits. Some of the parts they call out for are no longer available

or hard to find. You need to know how to substitute parts and understand how

the circuit will work without the right parts.

Books like the "OP-AMP Cookbook" are very good, they teach you a lot and have

fun circuits to build. Other cookbooks are for the 555 timer, TTL, and CMOS

type digital circuits.

(From Henry Spencer)

"The Encyclopedia of Electronic Circuits" by John Markus.

These are compilations of circuits published in journals and the like,

often with only the sketchiest of accompanying information. They're

potentially useful to experienced people as a source of ideas, but I wouldn't

spend more than $1 each on them (and I speak as someone who paid full price

for a couple of them).

Thomas M. Nathe seconds this: ""The Encyclopedia of Electronic Circuits"

(which I have) is more suited for more advanced folks. Some of the parts

[components] they call out for are no longer available or hard to find. You

need to know how to substitute parts and understand how the circuit will

work without the right parts.

(From Harry Y. Xu)

A large portion of IC's (integrated circuits) are digital. Knowledge of

these chips are very useful. They are fairly easy to understand too. As an

introductory to digital logic/electronics, I recommend:

"Digital Design Principles and Practices" by John F. Wakerly

Published by Prentice Hall

ISBN 0-13-212838

It's a fun, written in simple English, and no science or engineering

background is required [to understand it].

(From Jose S. Augusto)

I think the best text is the best to learn electronics is

"Microelectronic Circuits"

by Sedra & Smith (4th Ed.).

In the school, where I teach, it is being used for almost all of the

introductory courses. If you understand the 1000+ pages of the book,

you will understand almost everything about the subject :-).

(From Daniel E. Rudman)

"The Encylopedia of Electronic Circuits", Volume I by Rudolph Graf

(From Richard D Warner)

"The IBM PC from the Inside Out"

by Murray Sargeant and Richard Shoemaker

has a lot of good technical info on working with digital circuitry without

the "technobabble" you usually see [in other books]. The book is a little

dated, however. (They reference Don Lancaster's, "TTL Cookbook" a lot)

(From Jose S. Augusto)

[Book on SPICE models database]

"An effective approach to obtain model parameters for BJTS and FETS"

by S. NATARAJAN.

from Data Books: IEEE Tr. on Education, Vol 35, no. 2 , May 1992.

Almost all the fundamental transistor parameters are "extracted" from

Data Book information. If you have a data sheet for LM394 and 2SK152

you will probably get a close model.

(From Christopher Webster)

With regard to ECL, Motorola's "MECL System Design Handbook" (book # HB205)

is an excellent source of information. It describes the characteristics of

the various ECL logic families, provides information on using ECL with

transmission lines (coax, micro-strip, and stripline), and includes

application notes.

(From Peter Monta)

"Stepping motors and their microprocessor controls" by Takashi Kenjo,

published by Oxford Science Publications.

This book has an interesting explanations of operation, speed vs. torque,

why steps are missed at high acceleration, suggestions for drive electronics,

etc. You don't need to be a real motorhead to understand it, either; it's

not one of these electrical-machine E+M books that leaves actual application

as an exercise for the reader.

(From Andreas Springer)

[Update: This book is out of print - but it should be in the local library]

[replying to a post about using transistors in high frequency amplifiers]

A real good book is "Microwave Transistor Amplifiers, Analysis and Design" by

Guillermo Gonzales, Prentice-Hall 1984. As you see it's not the latest

one and the examples are only up to 5 or 10 GHz. But the basic principles

like smith chart, scattering matrix, etc. are very well covered and they are

valid at higher frequencies too.

(From Henry Spencer and John Whitmore)

Find a copy of "Digital Design with Standard MSI and LSI" by T. R. Blakeslee.

The first chapter or four is an excellent treatment of parts-reduction

schemes. But for God's sake, find the second edition! There is very little

difference in actual content, but the first edition is full of typos and the

graphic equivalent. In particular, there are some serious errors in the

illustrations for the section on Karnaugh maps, which is really pretty

devastating if you're trying to learn them for the first time... My copy is

full of my handwritten corrections. SO PLEASE MAKE SURE YOU GET THE SECOND

EDITION!

J.G.>

I found an ad for a company in Arlington, VA that claims to be the "only

company specializing in GPS seminars and books." _I have no idea_ if they

have anything worthwhile (I'm still waiting for their catalog :-), but

here's the info:

Navtech Seminars, Inc.

Navtech Book & Software Store

1-800-NAV-0885

R.B.L.>

Among other things, they sell the Guide to GPS Positioning, a 600-page

paperback introduction to GPS, which sells for around $35. Oh, by the way,

I'm one of the co-authors of the Guide and from time to time help out with

Navtech's seminars.

(From Ken Jongsma x7702)

GPS stands for the USAF Global Positioning System, a series of space

based transmitters that allow highly accurate positioning, worldwide.

The US DOD has guaranteed that Standard Positioning Service will be

available to any and all users for a minimum of 10 years.

This moderated mailing list was created after checking a number of

sources and finding no single location for GPS related topics. We

would frequently see questions posed in the Usenet groups

sci.electronics, rec.aviation, sci.aeronautics, etc. Apparently, a

number of you agree with the need for such a mailing list, as we have

received close to 150 subscription requests since our initial notice

was posted.

The GPS Digest is the home for all questions relating to the use of

products that incorporate GPS and related applications. GPS can and is

being used in navigation systems, surveying applications, precise time

source applications and many, many other areas.

It is our intent that the GPS Digest maintain a high signal/low

noise ratio. It is likely (at least initially) that several weeks or

more pass without a Digest. The interval will depend on the number of

submissions we receive.

The subscription list to date is diverse, both geographically and in

application interest. Addresses range from Switzerland to Australia.

Interests range from using GPS as a precision time source, to mapping

and navigation systems.

So, let's get started! Are you working on an interesting application?

Have a question on something? We're waiting to hear from you...

Communications Published by CQ ("Contesters' Quarterly" :-)

Quarterly to sort of apologize for taking over Ham Radio

(which used to be the most technical ham radio

magazine). Published four times a year and

fairly expensive, but has significant technical

content.

QEX Published by the ARRL; more technical content

and no contest results :-). Recently, they had

an article on DSP theory which served as a companion

to a DSP construction article in QST. Monthly, but

very thin; needs more contributors.

(From Mark Zenier)

Name: Nuts and Volts

Content: The want ads for the electronics underground. Recently added

some article and columns, which range from trivial to

incomprehensible, with some good stuff in-between.

Disadvantage: A lot of ads ;-)

Name: Computer Applications Journal (aka Circuit Cellar Ink)

Content: Practical applications of microcomputers, (with a higher

quality of engineering than the average in Radio-Electronics).

Along with some theory articles covering things like how to

synthesize holograms. Like an older copy of Byte, without the

reviews (so it's about 1/4 the size ;-).

** Trade Press magazines.

Name: Electronics Design

EDN

Electronics Products

Content: What's new and how to use it.

Disadvantage: Controlled circulation. Qualify or forget it (or pay a

lot of money)

III. Standards/Protocols

#### IBM PC and COMPATIBLES: ISA and EISA

(From A. Johnstone)

"The IBM PC from the inside out" revised edition, Murray Sargent III and Richard

L. Shoemaker, Addison Wesley, 1986, ISBN 0-201-06918-0

Covers assembly language and has some (not much) hardware interfacing

information. Revised edition includes some info on AT, but, again, not

much. Not a great book unless you are completely new to the game. Also

typeset in horrible sans-serif daisywheel (remember them?) typeface.

"Handbook of software and hardware interfacing for IBM PCs" Jeffrey P. Royer,

Prentice Hall, 1987, ISBN 0-13-381849-7

Very useful coverage of BIOS, DOS file structures and quite advanced

interfacing, including DMA, wait state generation and interrupts. XT only

(sigh). Recommended but a bit out of date.

"Interfacing to the IBM personal Computer" second edition, Lewis C Eggebrecht,

Sams, 1990, ISBN 0-672-22722-3

The author was the original PC designer, and, no, he doesn't explain why PC

interrupt lines are active high... However this book has the virtue of being

up to date with good coverage of XT, AT and PS/2 MCA buses. Lots of useful

hardware info and examples, although he fights shy of giving program listings

which is a shame. Highly recommended.

IBM technical manual for the PC. Has all the schematics and a BIOS listing but

no advice as to design strategies. I believe there are equivalent volumes for

the XT and AT, but I don't have them.

(From Jon Sreekanth)

"Programmer's Problem Solver for the IBM PC, XT and AT" Robert Jourdain,

Brady Book, 1986 (maybe a newer edition around), ISBN 0-89303-787-7

Published by Prentice Hall Press, NY

Not much bus detail, but lots of info on timer, keyboard, video, disk,

parallel and serial port hardware resources, and software interfacing.

"AT Bus Design", by Ed Solari, published by Annabooks, ISBN 0-929392-08-6

[possibly dated price] $69.95. Publisher may be contacted at 619-271-9526

Bus timing and specs, all the gory details. ISA and EISA.

(From Dale Roberts)

"Inside the EISA Computers" by Tony Dowden. Published by Addison-Wesley.

[possibly dated price] $25.00

It is an introduction to the EISA bus, and is meant to compliment

(not replace) the official specs from BCPR services.

(From info.dept.@canrem.com (info dept.) [fmg - no name given])

"PS/2 and PC BIOS Interface Technical Reference: Second Edition"

The above manual may be ordered directly from IBM Canada. It provides both

BASIC Input/Output System and Advanced BIOS interface information. It is

intended for developers who provide hardware or software products to operate

with the following products: PC, PC/XT, PC/AT, PS/2s, various display

adapters, and devices using ESDI-type commands.

It was published in 1988, order #: S68X-2341-00, $218 (plus tax(es))

"AT Bus Design" by Edward Solari, published by Annabooks.

Includes details for 8 and 16bit ISA, E-ISA, and EISA.

(From John Scafidi)

"Handbook of Software & Hardware Interfacing for IBM PCs" by Jeffery Royer.

(From Dale Roberts)

A quick note about the terms. MCA is microchannel architecture, which is

only on IBM's PS2 series computers. A *very* small market compared to AT

clones. The specs for the actual PC AT bus were never made public by IBM,

so there really is no official published standard for the PC AT bus. All

of the clone manufacturers had to reverse engineer the bus. As the official

standard for the 16 bit, AT style bus became the ISA (Industry Standard

Architecture), which was put together by a bunch of the larger clone

manufactures. The EISA bus was the industry's answer to IBM's faster MCA.

EISA is a 32 bit bus, with provisions for (among other things) 32 bit

transfers, faster DMA, and better bus mastering by the add in cards. It is

an extension of the ISA bus, so ISA cards can still be used in it. This bus

has only been available for a couple of years, and has just become affordable

for normal people in the past few months. Currently, EISA is a much smaller

market than the ISA bus, but EISA will certainly become the standard in the

near future.

As far as compatibility, in general, an 8 bit, PC style card will work in

the 16 bit ISA (AT) or EISA bus. A 16 bit ISA (AT) card will also work in

an EISA bus. EISA cards will only work in EISA busses. Note that some cards

may not work in faster computers with bus speeds of 12 and 25 MHz. Also

note that, for all intents and purposes, ISA and PC AT busses are the same

thing, but since the PC AT standard is proprietary IBM info, everyone has

to go by the ISA standard.

MCA is all alone... (and will probably stay that way).

If you want the official standard for the EISA bus, it is available from

BCPR services, in Washington D.C. Call them at (202)962-8349 and have them

send you the information packet. Warning: the specs itself is $125.00. I

have the information packet, but I haven't yet ordered the spec. Note that

since the ISA bus is a subset of the EISA bus, this document is the official

source for both standards.

The following book was very helpful in getting a card going on the ISA bus:

"Interfacing to the IBM Personal Computer", 2nd ed., by Lewis C. Eggbrecht,

published by SAMS, 1990-91.

Note: There is a first edition of this book which DOES NOT cover the AT

bus. You definitely want the 2nd edition. It deals with the 8 bit PC bus,

and the 16 bit AT bus, and is quite good. It is reasonably priced at

around $25 or so.

This next book I have heard good things about, and have actually looked at,

but the price stopped me from buying it when I first saw it. It is about

$70, and is a small paperback:

"AT Bus Design", by Ed Solari, published by Annabooks, 1990.

It deals with the ISA bus in detail.

(From Steve Baldwin)

There's a company called Annabooks that have a selection of PC/ISA design

books. I haven't seen them myself but they sound ideal and others have

commented that they have a wealth of information.

They run seminars too.

By far the most useful "real-world" book in this regard (that I've found,

anyway), which includes ISA/EISA/Microchannel specs, interface schematic

examples, etc., is:

(From Joseph Perry)

Both EIA/TIA-232-E-1991 and EIA/TIA-562-1989 contain an appendix which

gives recommendations on cable length based on cable capacitance. The

appendix gives a rule of thumb that the capacitance between a conductor

within the cable and the cable shield is two times the mutual capacitance

between conductors. In effect the appendix states that if you know the

mutual capacitance between conductors in a shielded cable you should use

three times this capacitance in computing maximum cable length.

#### X-10 protocol

(From James T. Wyatt)

[responding to an article on the net]

It was "Circuit Cellar INK" Nov/Dec 1992, as you found. It was not a feature

ardicle, per se, but part of a column called "From The Bench". This one's

subtitle was "X-10 interfacing with PLIX" which described a chip (PLIX) to

*GREATLY* simplify using X-10 with a TNW523 from the X-10 PowerHouse folks.

It was on page 74-79. The chip costs about $20 and is available raw or with

an evaluation board (and software) that plugs into a parallel port for $29.

They (MicroMint) will sell you a TNW523 for $20.

The address and contact information for MicroMint is:

MicroMint, Inc

4 Park Street

Vernon, CT. 06066

(203)871-6170

I used to subscribe to CCI, but got tired of *everything* having MMint

for it's only source, high $/issues ratio for a mag. full of ads., and

incomplete articles (leading back to point #1). Like Byte, it usually

had one or two issues a year that made me want to keep subscribed, but

times are harder now... :-( CCI does, I believe, sell back-issues. Their

office address is the same as MicroMint's, of course...

#### Electrical Wiring (household - USA specific)

(From John Whitmore)

_Wiring Simplified_ is a paperbound, inexpensive guide to household

wiring. It should be in about its 36th edition by now (it's updated

every time a new NEC comes out, NEC :== National Electric Code, the

US recommended standard that most local electric codes follow in this

country).

Look for it at any good hardware store; it's the one with the handy

hole for hanging it on a nail. It's even well written which comes

as rather a shock after perusing the net for a few hours.

(From Galen Watts)

For a concise listing of voltages, frequencies, and connectors, look in

the Panel Components Corp. Export Designer's Reference, available from:

po Box 6626

Santa Rosa, CA 95406-0626

1-800-662-2290

1-707-523-0600

Just a quick look shows 16 different connectors (8 in Europe alone),

10 different voltages and two frequencies, both 50 and 60 in Japan.

I have found the reference to be very helpful in preparing equipment for

use abroad, and I wonder how I got along without it.

are reasonable, considering they are the only comprehensive source I

mc68hc11-request@elden.cse.nau.edu will get you on a mailing list (Maybe)

elden.cse.nau.edu in the directory pub/hc11 (I think just hc11 though)

Motorola Freeware BBS 512-891-FREE (3733) (1200/2400 bps).

(From J. Babb)

There are two [that I know of] FTP sites for Motorola:

Try ernie.uvic.ca and calvin.stanford.edu

(From Steve Weigand)

I posted a C language-written Assembler for the MC68HC11 for anonymous

FTP on the University of Delaware's FTP site:

ftp louie.udel.edu

directory: pub

I think it's called assemhc11.c or something like that.

I don't think it's copyrighted... I didn't really check. If it is, someone

tell me and I'll remove it.

Anyway, it should work on just about any C compiler. I've compiled it

on an IBM PC, Unix, and Amiga... all OK.

I don't have any documentation, but if you look through the code, you

should be able to figure out what you can do and can't do with the

compiler.

There is a new ham directory at nic.funet.fi (Finland!)

/pub/ham/schema - directory for schematics.

Any schematics which may be useful others, may and should be uploaded to

there; especially ham related schematics, like preamplifiers, power

amplifiers etc. The format of file should be PCX, TIFF, GIF, EPS, PS or

ASCII. OrCad or EasyPC files are OK too, but they're not common and others

may have problems decoding them. Also, please remember to FTP them is

BINARY mode. If you can not, uuencode them first.

There is a good description by of how to build your own midi thru box in

midi-thru.gif at ftp.cs.ruu.nl in the directory pub/MIDI/DOC.

I used this schematic to build a 1 in 2+2 out box. Now I can direct the midi

output from my PC/sequencer to two groups of midi equipment independently.

The components were quite common and cheap (altogether less than 10 US$),

and there is nothing too complicated about the circuit.

V. Mail Order

(From John F. Woods - Date: Fri, 26 Feb 93)

[ $Revision: 2.11 $; last updated 12 February 93 ]

Here is my list of companies which will sell electronic components in

small quantities. Most of these places I have bought from, a couple

I haven't. Being a ham radio operator, I am most interested in

RF components, and in particular, air variable capacitors, which tend to be

scarce (and tend to be used or surplus even if I've otherwise labeled the

seller as "NEW"). I apologize in advance for disparaging remarks about

what happens when parts suppliers start selling computers, but anyone who

has watched Jameco over the years will know just what I mean (though

their latest catalog hints at possibly returning to selling parts).

Categories are:

NEW COMPONENTS Distributors and sellers of new components, or "new and some

used" in a couple of cases.

SURPLUS ELECTRONICS Usually overstocks, occasionally used equipment.

Ideal for stocking the junkbox, usually have dependable stock lines

of resistors, capacitors, and some semiconductors, but won't have

those LCD modules forever... An invaluable resource, don't shy away

from them.

SPECIALTY COMPONENTS In particular, crystals and toroidal cores.

KITS Ham radio kits, random electronic kits, whatever they have.

LITTLE GUYS Separated out because of some twisted sentimentality,

I suppose. Intended to honor one or two ham spare-bedroom

operations.

PUBLICATIONS Two publications which are essentially all want-ads, plus

the address for SAMS PHOTOFACTS because everyone always asks about

it on sci.electronics.

Note on shipping costs: I don't always update these frequently enough, and

they're generally for continental US unless otherwise mentioned.

NEW COMPONENTS:

(603) 635-2235

No minimum ($3 service charge if under $20), many kits, lots of J. W. Miller

chokes & coils, B&W coils, RF switches, Millen variable capacitors, lots of

parts in general. Send $1 for the catalog (but note that they are currently

(12-June-92) out of catalogs and it will probably be months before the next

one is ready).

Circuit Specialists Inc

P. O. Box 3047

Scottsdale AZ 85271-3047

(800) 528-1417

No minimum with check or money order, $15 otherwise. $3 S&H.

Catalog Subscriptions: (800) 992-9943 (Continental US only)

Sales & Service: (800) 34-MOUSER (800-346-6873) (US, Puerto R., Canada)

Very complete catalog of brand-new components (though no air variables).

Usually quick service, $20 "minimum" ($5 charge under $20). When ordering,

you may want to be sure to ask about availability and shipping locations;

they have several warehouses, and frequently orders will get sent from several

warehouses (which drives up the shipping costs).

Digi-Key

701 Brooks Ave. South

P.O.Box 677

Thief River Falls, MN 56701-0677

1-800-DIGI-KEY

No minimum, $5 handling under $25, free and very complete catalog, very nice

indeed. Prices aren't always the best, but rarely excessive. Weak on RF

specialty parts (though they now have the ever-popular NE602N), but they do

have blue LEDs.

Active Electronics

(800)-677-8899 (US)

(800)-363-6592 (Canada) [Not listed in current catalog, try US number]

$25 minimum, $5 S&H UPS, catalog has a "$10 Suggested retail price" but they

sent mine for free. They have 8 stores in the US (Santa Clara CA; Chicago IL;

Baltimore MD; Woburn MA; Detroit MI; Mt. Laurel NJ; Long Island NY; Seattle WA)

and 10 stores in Canada (Quebec City; Montreal (2); Ottawa; Mississuaga;

Winnipeg; Calgary; Toronto; Edmonton; Vancouver BC). Lots of stuff,

oriented more toward supplying last-minute requirements of companies than

hobbyists, but perfectly happy to take your money in small doses (stores have

no minimum order). The $25 minimum for certain items is no longer explicit,

but they note that some items will "ship in factory minimum package

quantities", which might be worse.

4801 N. Ravenswood Ave.

Chicago IL 60640-4496

(312) 784-5100

They don't have a single mail address or phone; instead, one is supposed

to call the closest of three pages worth of branch offices. I don't feel

like typing in the entire list (it's copyrighted, anyway :-), so send email

for your "local" distributor, or call their administrative offices at the

number above. They have a $25 minimum order; they are a Real Distributor,

but accept small orders (over the minimum, of course). Their catalog

currently 1248 pages; they are very complete (except, of course, for my

favorite scarce item, the air-variable capacitor). Note that the catalog

prices tend not to match reality all that often, so order by phone rather

than by mail; prices tend to be higher than other places, but they have a lot

of things that are hard to find from other outlets. Also note that they have

six Canadian offices, and one UK office, and will take international orders

$30 minimum order (was $50), >$5 shipping & handling. Their most recent

Over the past few months, a paper entitled, "Does America Say Yes

To Japan?" (Louis Leclerc 1992) has been circulated over various computer

networks and BBS's. Public response has been overwhelmingly positive.

The paper addresses the issue of U.S.-Japanese trade in the context

of our uncertain economic future. Mr. Leclerc provides the reader with

a wealth of referenced background and historical information concerning

our relations with Japan, as well as important facts concerning

ongoing developments which directly effect every American consumer/worker.

The paper, however, is not published and so is only available in the

form of circulating hard copies or electronic format. Anyone interested

I received quite a few responses on my previous post on building a GAL

programmer. Some of it is relevant to a large group of folks so I'm posting.

They accept VISA and Mastercard orders over the phone and will also

take a personal check by mail. The GAL programmer is in the April and

May 1992 issues. Back issues are $4 apiece. There is also a PC board

and software for use with an PC through the parallel port.

2. Serial communications using 68HC705K1:

To my total surprise I was able to get 9600 BPS communication using

this microcontroller. It doesn't currently function in full duplex

mode but for my programmer I don't need it to. I have to add the caveat

that it'll probably be difficult to do anything while transmitting

or receiving a character at that speed but if you need a 'get info -

do stuff - give response' loop then this is the way to go.

"Home recording for Musicians" and "Electronic projects for musicians"

by Craig Anderton. Both books are available from

PAiA Electronics

3200 Teakwood Lane

Edmond OK, 73013

Phone 405-340-6300

These books have several different plans for mixers, noise gates, limiters,

EQ, etc. Though both books are about 10 years old at this point, not much

has changed in design since then, although you could probably get quieter

op-amps now.

You might consider asking PAiA for their catalog first. They sell an

assortment of rack mount kits that turn into a home studio or DIY sound

reinforcement setup for a band. They also sell various MIDI kits. SSM

(manufactured by Precision Monolithics, I believe) has a line of chips that

are used in all sorts of pro-level consoles and synths, including things

like a single chip that handles balanced to unbalanced conversion, 40db

mike-to-line level boost, and LED drivers for clipping indicators.

The current issue of Electronic Musician has a dual compressor project based

on one of their chips, plus the address of PAiA and PMI. PLEASE use sockets

when you build, and unless you have some special supply of top-notch sliders

and a machine shop at your disposal, stick with rotary pots. I've tried to

make mixers with sliders, and they're a bitch, not to mention noisy. You'll

find you also have much more choice in knobs (sounds petty, but when you add

up 16 channels worth of knobs, it get pricey), in both price range and

style, if you stick with rotary.

(From John Whitmore)

There are SK and ECG and NTE replacement guides, which

list part numbers and give a brief description of a good replacement

device (good for transistors, spotty coverage for ICs). $5 or so,

and occasionally free.

There's IC Master which lists many (most?) current ICs

but doesn't give info on most (beyond three-word function description);

figure $200 for this one (published new every year).

There's the D.A.T.A. books (and a CD-ROM version) which gives

more info, and includes non-current ICs and such ($2000?).

And, there's an outfit (name disremembered) that has digitized

and indexed every data book they could lay their hands on, currently

about 45 CD-ROMs worth of info. $15k.

And then there's sci.electronics on the internet (estimated

cost: you can't afford one, but sending a single message costs

"hundreds if not thousands of dollars").

sensor. Gives DC output, 1.2mV/%RH, linear from 5 to 95%RH, +-2% accuracy.

Nothing in the blurb about temperature compensation or price.

Panametrics, Inc, (617) 899-2719

(From Vance Morrison)

For your information the September 1989 issue of Radio Electronics

(pp 65), has a article on humidy sensors. It describes how some of

them work as well as gives a list of places you can purchase them.

I highly recommend "The Cheap Video Cookbook" and "Son of Cheap Video"

by Don Lancaster.

[disposal of etching solution after use + disposal of other toxins]

This is covered in Steve Kasten's excellent book on home PCB techniques,

"Electronic Prototype Construction". I strongly suggest you buy this book.

Basically the safe home disposal process begins with neutralizing the spent

bath with caustic. Sodium hydroxide (lye) will be suitable. Use an excess to

precipitate insoluble iron and copper hydroxides. Take these solids and the

liquid and add them to Portland cement. When the cement hardens, it may

safely be disposed of in an ordinary solids-waste landfill. The alkaline

nature of the Portland cement tends to keep the iron and copper salts from

becoming soluble and leaching out of the solid.

Instead of using ferric chloride solutions to do the etching in our prototype

fabrication lab, we use a mixture of cupric chloride and hydrochloric acid

in water. The spent bath may be regenerated by the addition of hydrochloric

acid and water while bubbling air through the solution. The only problem is

that you generate more etchant than you started with. To dispose of this, we

neutralize with sodium hydroxide and evaporate most of the water. The solids

are sent to our high temperature waste incinerator where they fuse into the

glassy slag which is sent to a hazardous waste landfill.

The copper salts from the etching bath are particularly toxic to plant and

animal life so be sure and dispose of them safely.

"THE FFT: FUNDAMENTALS AND CONCEPTS"

by Robert W. Ramirez (Prentice Hall-1985)

It's great and explains everything very clearly.

['Plug' from a university that wrote a VLSI textbook]

Here's a bit more information regarding the new textbook

"Introduction to Mixed Signal VLSI," as excerpted from our brochure:

"Introduction to Mixed Signal VLSI" is written as a university textbook, but

with an industry perspective. The author, Dr. Donald Comer, has spent

several years in the semiconductor industry as a design manager for such

firms as Precision Monolithics and Analog Devices. He brings a real-world

feel to the classroom.

FEATURES

The key feature of this text is its inclusion of the right material

presented so as to allow its introduction to undergraduates. It is

intended to provide a single, unified course which replaces traditional

courses in analog and digital electronics. Other features include:

* Unified treatment of analog and digital circuits

* Physics and device manufacturing background presented with equal

emphasis on CMOS, bipolar, and biMOS processes

* Presentation of analog and digital circuits at an intuitive level

(with details of optimization left to be discovered by the student

via SPICE simulations)

* 250 end-of-chapter problems coordinated with SPICE simulations

* Solutions manual

* Supplemental laboratory/workbook

* Complemented by forthcoming textbook "Mixed Signal VLSI and ASIC

Design," by the same author. (Intended for follow-on undergraduate or

graduate course)
