Well after years of destroying electronic devices that never really belonged to you.. we finaly have a forum to talk about how great it felt anyways!

I truely look forward to the discussions that start here.. Myself, i can offer advice on PIC, some MOTOROLA, and of course any INTEL Asm/electronics you might have question for..

Also, a solid IwasTitan for voicing what us electronic people have been thinking all along...

Lastly, more thanks is deserving to our Lord, the Posted on 2003-03-29 01:22:36 by NaN
Thank you Hiro...Thank you Nan.

I cant wait for the first post.

oops i guess it is mine.


Ok what does "wtrs" mean on data sheets.

Now I can talk about all of the returned goods that SMOKE when I plug them into the tester :cool:

Ok what does "wtrs" mean on data sheets.

I think WTRs means: "Work to Test Relationships", "water treatment residuals" or "Wisconsin Telecommunications Relay System".
Maybee it's one of those "One Acronymn Multiple Meanings"-things.

(It could also mean "Windows Temination Reboot System" ;))

I'd suggest to move all Electronics-related past threads here.

Now someone may be able to tell me why my stupid Intel 80386SX-16Mhz burned up :)

I 2nd that suggestion

:grin: I Agree!!! This is a Great addition to an already Great Site!!!
Thanks, Titan, Hiro, et All

Did try pluging it directly to the main power grid? :eek:

btw, Any one with "first hand" infomation on how hard is it to build a "computer", a little one that has a little CPU, some RAM, maybe some storage that doesn't requre power to keep data, some port to comunitcate with a computer with (like RJ-45, DB9, DB25, USB), and to make software that interfaces with the "computer".
Does anybody got some site that might give me some basic tips, howto info, intructions, what to think of when building, etc. Yes, I will google for such, but please if you know some nice site please post a link.

More specifically from the pdf on the 24AA16 serial eeprom by microchip

Absolute Maximum Ratings?
VCC.............................................6.5V

All inputs and outputs w.r.t. VSS ......................................................................................................... -0.3V to VCC +1.0V

Storage temperature 65?C to +150?C
Ambient temp. with power applied ..........................................................................................................-40?C to +125?C


ESD protection on all pins ......................................................................................................................................................?4 kV

Anybody know what is meant by w.r.t on VSS

Maybe because you overclocked it to 3.4 Ghz ? :tongue: "Dern thang blowed up real good"

Thanx

I thought it might mean that.

hurray!!! :grin: :grin: :grin:
finally we got a dedicated forum part for EE :grin: :grin:

Damn,

You guys are lucky you can still see this stuff, I gace up analogue audio when I could no longer read 1% resistors with glasses on, the new stuff must be just about impossible to read without a microscope. :tongue:

Not at all hutch. The latest generation of SMD resistors, being .01 by .02 inches in size just don't have room for ANY marking.

So they don't get any.

Ceramic SMD caps never had a value on em. SOT transistors get a 2-letter code for the part number.

And after you buy all these tiny things to make your tiny board, guess what? You'll horde your PCB real estate so tightly you'll leave out the silk screen layer cause you can't spare the room to put down component designations.

The good news is you can make your assembly drawing in 38 point fonts if you wish. And that microscope is standard issue on the production floor.

what happens if you spill some on the floor? How do you know what is what afterwards?

Ernie,

This stuff would have to be fully computerised robot construction at that size with the human design component in the software that feeds the hardware to do it.

I am fascinated with technology of this type but its starting to get a bit remote for hobbyists. Earlier SMT could at least be done by hand if you had the right toys, things that were almost like high powered hair dryers for soldering but the stuff you talk about seems a generation in front of that again.

A multimeter, I guess. :)
