Electronic Design Guidelines.

Hi.

I am looking for a book in electronic or dead trees format with
guidelines for electronic design. That is, things such as maximum
allowed voltage on a capacitor related to nominal value, maximum power
on a resistor etc. I am working on a internal electronic design
quality assurance system and I need something to start from so I can
avoid reinventing the wheel.

TIA for any hint.

Elder.

"The Art of Electronics", 2nd Ed. Horowitz and Hill.

A bit dated in the microprocessor section, but still
the best available.  You'll not regret buying it.

Some things you just get from experience too, particularly if you had to 
repair older stuff that came back.

For example placing electrolytic caps beside a heat source such as a 
regulator is a problem in a couple of years..... heat dries up cap, 
capacitance goes down.... failure in some years.
Parts that produce plenty of heat are going to 
expand/contract/expand/contract as equipment is turned on/of constantly....
I've seen loose connections where the solder joints twisting apart due to 
metal fatigue.  Not so bad with thru/hole parts, but now with ceramic 
parts, there is very little space for flexing. Just because a part is rated 
for 1/4watt doesn't mean you should put 1/4watt thru it, because in a 
couple years, possibly, the solder joint is open.

Some things you simply have to gain from experience. Pity to the engineers 
who don't get their hands dirty once in a while and see what happens in a 
production environment but have only staed in the lab... never seeing the 
results of their work.  :-(
If you have access to manufacturing and repair, I highly suggest taking a 
wander thru them every now and then, ask questions of the people doing the 
work ;-)

Hope that helps.
Cheers!

Perhaps:

"The Design analsis Handbook; A pracitcal Guide To Design Validation"
N Edward Walker
Newnes publication
ISBN 0-7506-9088-7

I found it to be a good hands on introduction book.

Absolutely.

I fully agree. My own experience support this as we work as close as
possible with service and manufacturing people (though the plant is in
Manaus and I am in Sao Paulo :-) ) when designing. Not to mention
field research to check on problems which we learn a lot from.

Yet it's quite easy to forget some important things when writing a
guideline document.

Thanks and Regards.

That starts with the profession.
While electronic engineers tend to stay well below the rated
specifications, physicists tend to allow 10, 20% more than
specified. The later care less about the lifetime and have
it repaired by someone else.

Don't knock the dead tree medium. A short while ago I bought a book 
dated 1854. Immediately accessible using current hardware/ software 
setup. Try doing that with almost any electronic medium from 1974. 
(punched tape anyone?)

Once you are familiar with the hex codings for the ascii char set,
it is fairly easy to read 7 + parity punched tape with the Mark I
Eyeball.  I haven't practiced this for some time, though.  Parity
errors tend to slip through.

Now, 7 track 200 BPI mag tapes ....

I don't think he was.  When I really need to comprehend a file, I print it.

In school I programmed a Bendix G-15 tube computer to punch 5x5 dot 
matrix characters (I even generated the character set) onto 5 channel 
paper tape, then wrote a scroll to my girlfriend.  It would still be 
readable if it was saved (not likely).

> Now, 7 track 200 BPI mag tapes ....

I once saw a viewing device that looked similar to a liquid crystal 
panel, except that the liquid had magnetic particles so that you could 
view digital mag tape recordings!  It was basically a go/no-go kind of 
indicator.  You could locate the inter-record gaps and tell if it was 
recorded with 7 tracks or 9 tracks.  I doubt I could read the 
characters, even at 200 bpi, although you could probably spot a string 
of blanks.

Wow! I wrote mine to punch 5x7's and wasted altogether too much 
tape. I still have some of my old G-15 tapes - including an 
Intercom 1000D program used to plot a heart on a Calcomp drum 
plotter for my then-girlfriend.

Somewhere in storage I have a tape splicer and a bunch of mylar 
splices ( just in case the technology makes a comeback :-)

BTW, I (still) type (s)c7q89vz faster than any other character 
sequence.

RPG designs and designers
I'm not really sure where I'm going with this post... I'm making it because I am trying to replay Wizard's & Warriors, a game which I didn't comment much on when it was new. Why now? Because it's a better game compared to today's games then it was 5 years ago. First off, let me say I don't much like the game. For every good thing, of which there are many, there is a bad thing which counterpoints it. That's what prompted me to want to talk about design. DW Bradley was a golden child of RPG design, yet his last product was THIS. What was so good about his games? Some people like the flexibilty of his rule systems. But not me. DW Bradley games always result in parties made up of characters that are all good at everything. I dislike such designs... a lot. I want specialist characters, who are good at only 1 or 2 things. I could go on about how ridiculous it is to have a party full of redundantly uber characters for quite a while but I won't... some people love games like that. The game engine? The game engine in Wizard's & Warriors is shit. But I won't blame that on DW Bradley, he probably had nothing to do with it. What else then? Some people like the arbitrary mixture of european mythology and asiatic mythology. But, not me. It should be one or the other, but not both. I especially don't like the comic book super hero versions of Samurai and Ninja in his games. If he wants to make a heroic fantasy version of asian m...

Embedded System Design with Java
Has anyone successfully built an embedded product with an embedded Java VM? How did you build the board or did you buy one? Did you need to port the VM to your platform? We're you able to add custom device drivers to the Java VM? Any help here would be great. -Zach <pfefferz@gmail.com> wrote in message news:1165103075.662473.173000@l12g2000cwl.googlegroups.com... > Has anyone successfully built an embedded product with an embedded Java > VM?

Any help here would be great. > > -Zach Yes, I worked for a company who made smartcards with a Java VM. How more embedded can you get ;-) The first incarnation used the Sun Javacard reference implementation in C, which performed adequatly, so porting of the VM part was minimal (of course you have to handle comms and memory management platform specific) The subsequent versions used very clever inline assembler macros to use the processor facilities for a VM as much a possible. Drivers etc. were handled by a Hardware Abstraction Layer API to facilitate porting. To aid the developers, we also had a port to Windows, so not everyone needed a rare and expensive emulator for Java development. Wim ...

Design Hardware for Embedded Systems
Hello all. I would like to know how can I design the hardware of my embedded system. Right now I just have an idea of a project, a processos family that I probably will use, and a few perifericals that would be present. I would like to know how can I build the hardware of this system, what metodology and tools to use. I would like to build a system with those hardwar pieces (Microcontroller + Periferials), test it, and then start working on the software for my hardware design. I have looked at tools like RealView for ARM development. It looks like that with this tool I can work from the point I am right now to develop the hardware and software of a embedded system. Other tool that I have checked is Proteus VSM. Are those the correct tools to work with. Are there any free or open tools that I could use? I don't know if I made myself clear with my above explanation. Basicly I would like to assembly my microcontroller and periphericals in a system, to build and then test my hardware design. Then, I also would like to build the software for this hardware. I have some experience with the software design, but no experience at all with the hardware design, so I need more help in this part. Thank you very much for any help, I really need it! If you need any futher information in order to help me, please let me know.
