Chessmaster, do you stick your fingers into light sockets?

Everyone on this board uses computers, or at least mobile devices. These PC-AT numeric keypads have been around now since the mid 80's, long before the mobile web devices. I believe that some people must use them, or at least they've considered it if they have had to enter a long list of numbers.

OT: Bio-Magnetic SensorsBasic introduction to bioelectromagnetics (2009 CRC Press)

Basic introduction to bioelectromagnetics / Carl H. Durney, Douglas A. Christensen (2000 CRC Press) tuscl.net

I'm going to read both the above books, CRC Press, and starting with the older.

Yes, as I know superconductivity has always depended upon liquid He, boiling point of 4 deg Kelvin. Very expensive. But like this is how the big accelerator at CERN in Geneva works.

And then there was a plan to build one like it in Texas. $20 billion way back then. But it got cancelled.

One of the justifications is that they want to be using the less costly LN2 temp superconductivity, so called high temperature super conductivity.

But I don't think anyone really knows how this works.

SLAC is working on it.

Right here: today.slac.stanford.edu

But these ideas that the Japanese components maker is talking about are room temperature magnetic. Using ferrite. en.wikipedia.org

They say that Japanese invented ferrite. Anyway, it has been common in electronics, as I know, back into the 1920's, RF transformers and for the tunned IF transformers in radio receivers.

SJG

san_jose_guy7 years ago

Well at the above wikipedia it says that ferrite was developed in Japan in 1930, and that that led to the formation of TDK. Well, a proud history, as ferrite has been extremely important in radio frequency electronics ever since.

I used the numeric keypad a lot. No big deal to me. If you work with spreadsheets on a computer or lots of numbers, it's common to use the right side of the keyboard.

san_jose_guy7 years ago

Are you entering material which is on paper? Where do you place the paper realative to the keyboard, like underneath it, or closer to you?

How many other keys are you needing to use and does this necessitate using your left hand?

Good to hear that someone finds it useful.

Thanks, SJG

So old mechanical adding machines had to have all 10 digits per place in the number. 1stopretroshop.com

Then they figured out how to make them work with just 10 keys d2ydh70d4b5xgv.cloudfront.net

Then they figured out how to make them electronic. img0.etsystatic.com

So truth to tell, I was once employed repairing such.

I wanted a home town summer job. But how does one get that, if there is not some channel whereby it is being handed to you? So knowing nothing I looked in the newspaper and wrote some things down. Finally though I went to an employment agency.

This was real stupid because they would charge the employer, and they would also charge me. And if it is just for the summer, it is not worth it. But I went anyway, filled out their application. Soon they sent me out to a first client. It went splendidly. They had some kind of a qualifying exam and they were totally blown away by how well I had done. Never before had they seen that.

This was a transnational corporation. And the regional manager also had his office there. He might have written the test. He was totally blown away. So he took over and quickly rigged it so I would for one month be on the payroll of one of their customers, who would be given compensatory credit, cutting out the employment agency. So I started the next day.

This was lucky for me that it all worked out so well. And it turned out that I was getting much more money than what my classmates tended to be getting for summer jobs.

I wanted it, well I think just because other people were doing it. Obviously I did not have any real plans, did not know what I was doing.

So the next day and I was repairing 10 key electronic printing calculators.

They liked me and my exam so much that they were showing it all around in this transnational corporation. They wanted to make me the lead person for their new product, a word processing typewriter.

After a few months though they backed off, they said that it was not right to try and lure me out of college.

They said that having me made things good for them, as they could then screen lots of people for the position. No one ever equaled what I did on their exam.

All and all a good learning experience.

So @orionsmith, when I first saw that keypad, on a Compaq PC-AT clone, it at once reminded me of the 10 key printing calculators. So as I know, people would keep biz records in some kind of a ledger, and then use such a machine to add up the totals. Maybe attach the paper tape to the ledger book.

You talk about using a spreadsheet. Well with that I imagine that you are not only entering numbers, which I assume to be money, but also entering transaction descriptions, alpha numeric. And then dates?

So as I know, not many people use that right side key pad. But it could be useful. But then, how much other use do you need to made of the qwerty part. And then if it is just a couple of numbers, still use those over the qwerty part?

Use the right hand key pad for dates too? Use the "/"?

For me, computers on desks have always been a horrible compromise at best. Okay if it is just the computer. But add any book or piece of paper and it gets real hard. Could have the keyboard on a slide out shelf below. Could support the monitor on a springs and friction thing, so it is totally off of the table.

Or like this, nothing under the monitor until the very back of the table surface. images-na.ssl-images-amazon.com

And then the mouse takes up problematic space too.

Of course more and more, the data is just always already in the computer. Not clear how it originally gets there. But less use of anything on paper.

I think that right side keypad is great. But maybe need some other keys added to it or something, or software to let you make special use of '/*+-". Maybe need to reshape it a big for the thumb on the '0'. Maybe a backspace or a tab.

And any interface which uses the mouse of course really slows people down.

I have know people who do not even like the arrow keys, Wanting instead to use a, s, z, w with the control key. It goes faster. They don't like function keys either.

That would be my next issue too. On AT keyboards there are 12 such function keys. I think they are underutilized, ever since the mouse took over.

Mostly it just takes people being willing to learn to use the right side numberic key pad.

So still not finding the answers I want.

AIK:

Seymour Cray introduced 80 bits, on the 16bit Cray 2. People had asked for it, and they loved it.
IBM PC left an undocumented open slot for the Intel 8087, a kind of a gambit on the part of both parties.
PC-AT used 80286 and had documented slot for 80287. Still 16 bit machines with 80 bit floating point.
80386 introduced a 32 bit mode, called IA-32, but MS-DOS could not use this. Not used until Windows 3. But 80387 was available and often used.
80486 has come troubles getting going, floating point troubles. But I think this was where they made the 80 bit floating point processor built in.
Pentium, the 80586, but Intel announced that that would be the last of the line.
Pentium III introduces 64 bit architecture IA-64.
Today they talk about 7th Generation, 8th Generation, 9th Generation, I guess the way they are extending beyond the 586 5th generation. But what is the status of floating point processing? And is it the same on all their processors? ARM seems to use 64 bit. To me, this far out, 64 bit is not adequate. Needs to be 80 bits or more.

So can I find more info about the status of Intel's processors and their floating point offering?

Here they talk about a floating point bug in 1994 Pentiums en.wikipedia.org

Here it talks about their 7th Gen, as would be standard in the Dell I was looking at as an example. newsroom.intel.com

newsroom.intel.com

newsroom.intel.com ^^^^^ Running from 4.5 Watts to 91 Watts. 14nm technology. Mostly talking about graphics and media.

Yes, the Core version and the much higher powered Xeon version.

Actually tables and tables of very complex info. PC's are getting closer and closer to system on a chip.

But never is even a word said about floating-point.

Here is something AVX ( Advanced Vector Extensions ) improves floating-point and can do 256 bit Integer operations. newsroom.intel.com page 5 of 14, and on these 7th Generation, not the newest but kind of the base price offering.

A lot of support for graphics and data transfer, and security, and for multi-threading.

Sounds like BIOS is in onboard flash, and there are all sorts of protections. ( all gotten very complex )

Talk about such stuff here, mostly about OpenMP, Vectorizing, and Paralleling. software.intel.com

Microsoft Document talks about AVX docs.microsoft.com

"Intel AVX is a new 256-bit SIMD FP vector extension of Intel Architecture. It accelerates the trend towards using SIMD technology for floating point computations in general-purpose scientific calculations such as financial derivative pricing. Intel AVX is a comprehensive ISA extension of the Intel 64 Architecture."

"Single instruction, multiple data (SIMD), is a class of parallel computers in Flynn's taxonomy. It describes computers with multiple processing elements that perform the same operation on multiple data points simultaneously."

"In computing, Streaming SIMD Extensions (SSE) is an SIMD instruction set extension to the x86 architecture, designed by Intel and introduced in 1999 in their Pentium III series processors as a reply to AMD's 3DNow!. SSE contains 70 new instructions, most of which work on single precision floating point data."

en.wikipedia.org Talking about Intel having built in instructions for 128 bit floating-point going back some time.

(That would be really cool! but better to run out outboard processor which is not burdened by Windows and graphics stuff?)

Intel Intrinsic Guide

software.intel.com

Consistency of Floating-Point Results using the Intel® Compiler software.intel.com

Compiler options let you control the tradeoffs between accuracy, reproducibility and performance. Use

/fp:precise /fp:source (Windows*) or -fp-model precise -fp-model source (Linux* or macOS*)

here is a 22 page pdf which should explain more: software.intel.com

The Intel® Compiler implements a model for floating-point semantics based on the one introduced by Microsoft. 1 A compiler switch (/fp: for Windows*, -fp-model for Linux* or macOS*) lets you choose the floating-point semantics at a coarse granularity.

Seem to have both C/C++ and Fortran. ANSI standards about how much compiler can do in its optimizations are different for those two.

(This sounds like very high powered shit, if I do say so. And so much for Fortran being dead.)

Talks about weather research and forecasting, and MPI ( message passing interface )

software.intel.com need to look up some of the refs at the end of this, about Intel's two compilers, maybe try to find some books too.

Nirvana - Come As You Are youtube.com

This song in my head last night. It must be in the Key of D.

Most everyone can hear relative pitch. But very few can hear absolute pitch. The reason every key sounds different is because the percussion tuning is not changed. Musicians deny that percussion is tuned to any specific pitch, saying that rather it is just tuned until it sounds right. But that is silly, because that is exactly how a violin is played, by making it sound right. Tympani tunes with a crank handle, and it has a gauge right on it. So the kick drum is tuned to A of the 16ft octave, the same as the second to lowest string of a four string bass, 55 hz. All the drums are tuned.

These kind of songs are always in D. I think it has something to do with that A note, the dominant.

So to really know you almost have to play along with it. The D scale has F and C sharped. But it can be done with accidentals too. And some music revolves around other notes than the tonic. Some is Mixolyidian and so it revolves around the dominant and has the 7th ( C# ) flatted. Lots of ways. In the end it is just listening to it and trying to play along which will resolve this.

This ends on the D major triad and the chorus versus end on the D major triad. Usually that is the final determinant of what key it is in.

Alternate guitar tuning is being used, one suggestive of D.

Some assembly required : assembly language programming with the AVR microcontroller / Timothy S. Margush (2012 CRC Press) CRC Press books are always good!

Book is very well written, explains lots of important things which other books would leave out.

So did AVR start with Atmel? And ARM too?

AVR has 32x 8 bit registers. Never heard of anything like that. Good for mutitasking, but I don't think compilers would be able to put those 32x registers to good use. Need to do that yourself in assembler.

AVR uses this Harvard Architecture with separate memory and busses for data and code. Should be able to use pipe lining to go faster.

So it has an SRAM space, which is the data and stack segment. Then it has a Flash memory, which is the code segment. Then it has an EEPROM section which is the extra segment.

They say the Flash can take 10,000 write cycles, where as the EEPROM can take 100,000. Don't know what technology is used in the EEPROM, or how much different it really is from the code.

AVR Studio is supposedly the software for developing.

avr-studio.informer.com free download? seems to talk about C/C++. Maybe assembler is just understood?

san_jose_guy7 years ago

So continuing with: Some assembly required : assembly language programming with the AVR microcontroller / Timothy S. Margush (2012 CRC Press) CRC Press books are always good!

So this board, $79, has lots of sockets, for many of their various products. Not sure how you get an AVR into it, 4 sided square surface mount package. microchip.com

SO getting to serial communicaitons. Can be synchronous or asynchronous. That former requires sending the clock. Usually not done this way.

With with async, you can send one way data with just one signal wire and ground. Two way data takes ground and two signal wires.

So this always confuses people, DTE (data terminal equipment) DCE (data commuications equipment)

DCE was typically a modem and the DTE was a terminal.

Used to be 25 pin.

With IBM PC changed to 9 pin. People call this DB-9. But proper terminology is DE-9

So DTE has TD(transmit data) on pin 2, and RD(receive data) on pin 3, Ground is pin 5 DCE reverses 2 and 3.

Null modem cable or adapter reverses 2 and 3

From memory if you use the DB-25 way, there are three pairs which need to be reversed.

RS-232 still needs plus and minus 12 volts. The STK-500 has a level shift chip to do this.

Serial data frame can have a parity bit and 1 or more stop bits.

This book uses ATMEGA16A and an ATMEGA128A1

Can do Polled I/O or Interrupt Driven I/O

AVR chips come with boot loader in the flash. You can add constants / config to EEPROM, 8.5 mS for each right. ( Still don't know how this works.

I would want to run almost entirely out of the SRAM, not Flash or EEPROM.

SJG

san_jose_guy7 years ago

So finishing up with: Some assembly required : assembly language programming with the AVR microcontroller / Timothy S. Margush (2012 CRC Press) CRC Press books are always good!

CRC part of Taylor Francis taylorandfrancis.com

So I am going to try and capture all I want from the entire book, as it is complex and some does need this additional treatment.

so they talk about the Atmel ATmega16 microcontroller, shown in the traditional microprocessor through the hole package of a wide 40 pin DIP.

THey show their STK-500 Development Kit. It actually has a bunch of sockets, including the standard narrow DIP. These can take their PIC chips.

So lots of stuff can go into this $79 board, though presumably only one at a time.

Then they also talk about a much more powerful AVR, though still 8 bits. And it is surface mount and you use it on the AVR XPLAIN demo board. It has no sockets, though it has some other chips to make it all work. This board has USB and a special chip for that. Whereas the earlier board seems only to be RS-232.

Both have momentary contact buttons and LEDs.

To explain these they show you a Digital PDP8/E, to get across the idea of switches and lights. i-programmer.info

I remember using such, the switches and the magnetic memory cores.

Says these AVR processors run code from the Flash Memory. Not sure if this is always true. I would want to run most of it from the Static Ram most of the time.

So we have the Stack, as we have function calls. But we have dynamic memory allocation, and so we also have the Heap.

So want to revisit this complex but critical topic of Serial Data Communications.

DTE ( Data Terminal Equipment )

DCE ( Data Communications Equipment )

So a modem would be DCE, and then the terminal which connects to it is DTE.

So a Null Modem cable or adapter reverses some connections.

So it used to be 25 pin, and you had to reverse 3 different pairs. Could be a much more complex handshaking set up.

But with PC's and the PC-AT they went to 9 pins, commonly called DB-9, but more properly called DE-9.

So they call it the PC Signal Set, but more properly it is EIA/TIA-574

hardwarebook.info

So with DTE, pin 2 is transmit data, pin 3 is receive data. Pin 5 is ground.

With DCE, pins 2 and 3 are reversed, pin 5 stays the same.

So one way communications only needs ground and one other wire. Need ground and two other wires for 2 way communications.

So RS-232 needs both plus and minus 12 volts. The demo boards have a level shift chip to accommodate this.

So they call mark, usually draw high, as -12 volts. When the signal drops to +12 volts, the call this Space, and that first drop is Start, and this is when the PLL starts to lock up.

So then data bits can be between 4 and 9, and then one or more stop bits.

Usually using asynchronous, but if you want to use synchronous, you need to also send the clock. One will be master, one will be slave.

So now we are going to talk about Interrupts. There is a non-maskable interrupt. But on these AVR's, that is the same as Reset, and it can trigger on either edge change!

You can use interrupts to eliminate switch bounce.

Finished with. Basic Introduction to Bioelectromagnetics I have the 1999 edition. There is a newer edition. Let me see if I can find anything about it.

2009 second edition: crcpress.com

"Example applications include hyperthermia, neural stimulation, MRI, NMR, ultrasound, and cardiac pacing/defibrillation. "

2nd Edition Preview crcpress.com

Yes, the second edition does have some good stuff in it.

We also have this: Bioelectromagnetism : principles and applications of bioelectric and biomagnetic fields / Jaakko Malmivuo, Robert Plonsey. 1995 ^^^^^ looks more interesting.

Yes, the above looks like the one to read next.

So about the one I read, it reviews electromagnetism, and it shows that running from maybe 100Mz to 1000Mhz you can get a skin depth in the human body of about 5 to 10 cm maximum. You can find fluid in the lungs and abscesses to an extent.

But there is no talk about reading eeg or heart muscles by magnetic fields, or about using superconductivity and Josephson Junctions.

Bioelectromagnetism : principles and applications of bioelectric and biomagnetic fields / Jaakko Malmivuo, Robert Plonsey (1995)

First author is in Finland at the Ragnar Granit Institute.

And he dedicates the book to this Ragnar Granit (1900 - 1991), bioelectromagnetism pioneer and Nobel Prize winner.

Second author is at Duke University, Durham, North Carolina

So in 1963 Baule and McFee measured the first biomagnetic signal, the magnetocardiogram, MCG. They did this by winding 2 million turns of copper wire around a ferrite.

Actually it was two ferrites, counter wired in serious to cancel out other magnetic effects.

So this must be what Japan's TDK is talking about.

So you can measure the heart, but it is different from what I was expecting to see. And you can measure more if you use SQUIDS. And right now they are only talking about the very expensive LHe, not LN2.

And as far as brain waves, really cannot measure much without SQUIDS.

So sometimes magnetic cardiogram has advantages over electocardiogram. But best is when both can use used together. But SQUIDS and LHe is very very expensive.

So brain waves are about 100 microvolts at the scalp. But about 1 to 2 millivolts directly at the brain.

I do have past experience in these matters.

Now, as it has been for over 100 years, where the science stops, the New Age Metaphysics begins.

Lots of talk about neural anatomy.

3 kinds of muscle. Smooth and the Skeletal Striated. The third is Cardiac. It is striated like the skeletal, but there is another difference. It is coupled together electrically so that when one cell fires, they all fire.

So Cardiograms can be done magnetically. Ferrite can get readings. But clinically it is always done with SQUIDs.

To do Encephalogram magnetically, it has to be done with SQUIDs.

Electrocardiograms use 12 wires.

Electroencephalograms can use up to 21 wires.

Magnetic fields ( Vector Curl ) are created by charge carrier movement ( drift, angular momentum, or spin ), but they are also created by time variance in the electric field ( displacement current ).

Read this guys stuff decades ago. Interesting, but I still think it was going over my head.

John H. Holland

Adaptation in natural and artificial systems : an introductory analysis with applications to biology (1975)

Emergence : from chaos to order (1999)

Hidden order : how adaptation builds complexity (1995)

Induction : processes of inference, learning, and discovery (1986)

Signals and boundaries : building blocks for complex adaptive systems (2012, 308 pages, seems to have been his last book)

^^^^ very available!

A lot of this stuff, it is not that interesting in the abstract. But when you start to talk about applying it in a signal detection or machine decision making situation, then it is very interesting, non-linear signal processing.

Okay, Dreyfus mentions this, and it is in libraries:

Computation and human experience / Philip E. Agre (1997)

And we have other books by this same author, from that same late 90's era.

SJG

san_jose_guy6 years ago

ALso this from Agre:

Philip E. Agre,The Dynamic Structure of Everyday Life, MIT AI Technical Report 1085, October 1988, chapter 1, Section A1a, 9.31Agre,Computation and Human Experience, 243. His ambitious goal was to “develop an alternative to the representational theory of intention-ality, beginning with the phenomenological intuition that everyday routine activities are founded in habitual, embodied ways of interacting withpeople, places, and things in he world.”32Ibid, xi.

SJG

san_jose_guy6 years ago

Totally cool, 2 volumes:

Essays in honor of Hubert L. Dreyfus / edited by Mark A. Wrathall and Jeff Malpas. (2000), dealing with these issues!

And Dreyfus is using this translation of Heidegger: Martin Heidegger,Being and Time, J. Macquarrie & E. Robinson, Trans. (New York: Harper & Row, 1962)

SJG

san_jose_guy6 years ago

From the Dreyfus paper:

"For example, while biking we can observe passers by, or think about philosophy, but if we start observing how we skillfully stay balanced, we risk falling over."

also take note of:

Brooks, “Intelligence without representation”, 418.

Michael Wheeler,Reconstructing the Cognitive World, 285.

Wheeler’s well informed book could not have been more timely since there are now at least three versions ofsupposedly Heideggerian AI that might be thought of as articulating a new paradigm for the field: Rodney Brooks’behaviorist approach at MIT, Phil Agre’s pragmatist model, and Walter Freeman’s neurodynamic model. All threeapproaches implicitly accept Heidegger’s critique of Cartesian internalist representations, and, embrace John Hauge-land’s slogan that cognition is embedded and embodied.

How brains make up their minds / Walter J. Freeman. (2000)

Walter_Jackson_Freeman_III en.wikipedia.org

Taught at UC Berkeley, passed away in 2016, Fellow of IEEE, and in charge of their neural networks section.

Studied Mathematics and Physics at MIT.

In 2008, Freeman proposed that Thomism is the philosophical system explaining cognition that is most compatible with neurodynamics.

Michael Wheeler,Reconstructing the Cognitive World: The Next Step(Cambridge, MA: A Bradford Book, The MIT Press, 2007)

Heidegger and cognitive science / edited by Julian Kiverstein and Michael Wheeler (2012)

Reconstructing the cognitive world : the next step / Michael Wheeler. (2005)

This author also good and relevant

Kiverstein, Julian

Looking back, Winograd says: “My own work in computer science is greatly influenced by conversations with Dreyfus.”

John Haugeland, “Mind embodied and embedded,”Having Thought: Essays in the Metaphysics of Mind(Cambridge, MA: Harvard UniversityPress, 1998), 218.

Terry Winograd writing about what happened at MIT, after he left for Stanford:

For those who have followed the history of artificial intelligence, it is ironic that [the MIT] laboratory shouldbecome a cradle of “Heideggerian AI.” It was at MIT that Dreyfus first formulated his critique, and, for twentyyears, the intellectual atmosphere in the AI Lab was overtly hostile to recognizing the implications of what he said.Nevertheless, some of the work now being done at that laboratory seems to have been affected by Heidegger andDreyfus.

Hubert Dreyfus,What Computers Still Can’t Do: A Critique of Artificial Reason.MIT Press, 1992, 265–266.

Still, Brooks comes close to an existential insight spelled out by Merleau-Ponty, viz. that intelligence is founded on and presupposes the more basic way of coping we share with animals, when he says:

"The “simple” things concerning perception and mobility in a dynamic environment...are a necessary basis for“higher-level” intellect....Therefore, I proposed looking at simpler animals as a bottom-up model for buildingintelligence. It is soon apparent, when “reasoning” is stripped away as the prime component of a robot’s intellect,that the dynamics of the interaction of the robot and its environment are primary determinants of the structure of its intelligence."

"The work can best be described as attempts to emulate insect-level locomotion and navigation....There have been some behavior-based attempts at exploring social interactions, but these too have been modeled after the sorts of social interactions we see in insects."

Surprisingly, the modesty Brooks exhibited in choosing to first construct simple insect-like devices did not deterBrooks and Daniel Dennett from repeating the extravagant optimism characteristic of AI researchers in the sixties.As in the days of GOFAI, on the basis of Brooks’ success with insect-like devices, instead of trying to make, say, anartificial spider, Brooks and Dennett decided to leap ahead and build a humanoid robot. As Dennett explained in a1994 report to The Royal Society of London:

A team at MIT of which I am a part is now embarking on a long-term project to design and build a humanoidrobot, Cog, whose cognitive talents will include speech, eye-coordinated manipulation of objects, and a host ofself-protective, self-regulatory and self-exploring activities.

(Brooks is okay, but I have long been very unimpressed with Daniel Dennett)

Maurice Merleau-Ponty,The Structure of Behavior, A.L. Fisher, Trans. (Boston: Beacon Press, 2nd edition 1966).

“It’s like claiming that the first monkey that climbed a tree was makingprogress towards flight to the moon.”

Burlingame

With over 55,000 square feet of manufacturing area in two buildings, our Printed Circuit Board Assembly and Electromechanical facilities are located in Burlingame, California - just outside of the Silicon Valley, centrally located between San Francisco and San Jose, California. With Sales offices in Burlingame and San Diego California. abxengineering.com

Right on the bay front, and very close to SF International, but yes, strictly in Burlingame.

These guys must know what they are doing. Not sure myself how much of this kind of work still goes on in this country, and especially in the bay area. Don't have a sense of what their applications are and who their customers would be.

Not sure if their photo tour could be very old.

The experience and history of ABX has given us a robust supply of vendors both in the US and off-shore allowing ABX to fulfill customer demands through the most efficient use of resources, inventory, automation and labor. The ABX supply chain includes working with key suppliers to eliminate bottlenecks, sourcing strategically to strike a balance between lowest material cost logistics, implementing JIT (Just In Time) techniques to optimize manufacturing flow, maintaining the right mix and location of vendors to serve our customers production needs.

Yes, most of the people I know who are involved in such do emphasize off shore.

Should be able to make onshore and local work.

Don't like this guy, but I would like to read his book. amazon.com

Logitech® Wireless Desktop Keyboard And Mouse Combo, MK345 officedepot.com

2.4GHz speed delivers a reliable, long-range connection. Operating range of up to 30' (actual wireless range may vary with use, settings and environmental conditions).

Uses 2 AAA batteries for keyboard, and one more for the mouse. Batteries could last 3 years!

These kinds of things use to be 980 Mhz.

This is 2.4Ghz, but I don't think it is WiFi. 2.4Ghz is open to using different ways.

Wireless keyboard w/ trackball might be better

Muffin Fans, and 120V AC is liked better. partstown.com.mx

And small as they make 'em would be best.

120mm, quite big! amazon.com

80mm, still way too big! amazon.com

80mm and larger acinfinity.com

Maybe 40mm, but 12V DC. They do sell grill covers. galco.com

DC Axial Fans galco.com

The big fans are too much air flow, but also too much size and too much noise. 40mm is okay, but smaller would be even better. But they are 5 or 12 volts DC. 12v better than 5v. But 120 volts AC better still.

For AC power, looks like 80mm is the smallest.

They sell fan grill plates, but I am not seeing filters and their mountings.

How about opto isolated and triggered triacs?

Here is a triac, nice thermal mounting too. galco.com

$10.

Isolated from its thermal mounting. But not seeing optical isolation for triggering. They say good for microwave ovens. Well probably nothing is isolated electrically there.

Opto Couplers, though not in the same module as the Triac. bristolwatch.com

ATC-Automatic-Timing-and-Control-Solid-State-Relays galco.com

^^^^ This stuff has its uses, but mostly too big, and not seeing the opto-isolation. Also, if you still have to get triggering current from the unisolated side, is that not being done in thermally inefficient way, resistor drop?

Also, can IGBT do this and be directly optically triggered?

Triac should be possible to directly optically trigger.

Like this, but still my same questions quora.com

MOC3020 or MOC3023 qph.fs.quoracdn.net

Optocouplers / Isolators - IGBT and MOSFET Driver vishay.com

Optical Isolation for Solar Power vishay.com

^^^^^ Interesting stuff! They even seem to have opto controlled power MOSFETs. Lots of new uses of opto isolation for solar power systems

IGBT Drivers Optically isolated IGBT drivers are used to isolate the high voltage stage of an DC/AC inverter from the low voltage control circuitry. Isolation is required for safety purposes because string inverters are inverting a high voltage DC output from the solar panels to a high voltage output that will be fed to the utility grid. This high voltage must be isolated from the user-accessible low voltage circuitry. Optically isolated IGBT drivers also allow the designers to separate low noise control circuitry from noisy high voltage and high current circuitry, which improves performance, shrinks product size, and simplifies the design process.

RS-485, well worth reading: en.wikipedia.org

Chapter on RS-485, CRC Press, always good. Networking and integration of facilities automation systems / Viktor Boed ; with contributions from Ira Goldschmidt [and others].

RS-485, 10 Mbaud max. Can use four wires for full duplex, but can do two way data on just one pair.

Max Baud times distance in meters should not exceed 10E8. So 10 M would be for 100 meters. Max length ever is 1200 Meters.

Termination should be 3 resistors ( pull up, load, pull down. ) Lines float and screw up without the pull up and pull down.

80mm 120V AC fans, but which way to they blow, I want them to blow in. And not really good for mounting upside down.

acinfinity.com

cooltron.com

I guess this could be mounted the other way: cooltron.com

SJG

san_jose_guy5 years ago

Spec sheet shows air flow, but you cannot tell which direction they have drawn fan. I guess this fan can be mounted either way.

acfdserver.com

Loud kinds of fans, but better than having to make bigger power supply to run fan.

about 5 watts of AC mains power.

san_jose_guy5 years ago

Making these software shut down and reset, and momentary contact on/off switch circuits is not that easy. Need to read more. How it works in lap tops is one thing, DC only. But on other stuff with the AC power mains, quite tricky.

This is still DC only pdfserv.maximintegrated.com

So I clearly want books about Triacs and about IGBT's, and for use in controlling the 60hz power mains for modest scale appliances, particularly interested in DC triggering for both alternations.

Triacs: Electronics : circuits and systems / Owen Bishop 2007 Industrial electronics for engineers, chemists, and technicians : with optional lab experiments / Daniel J. Shanefield. (2001)

Read older books first

IGBT

Complete guide to semiconductor devices / Kwok K. Ng (2002) Power electronics : devices, circuits and industrial applications / V.R. Moorthi (2005, had found this before)

This guy has a power semi book, but it is old and hard to come by.

Well here, 1979 Solid-state power electronics / by Irving M. Gottlieb

Worth reading first, has other devices. I read it many years ago. Other books of Gottlieb about power supply design are available and well worth reading.
