The biggest problem is that the complexity of government has outpaced
the capability of 99.999999% of the solaced populace. So what can be
done? They shouldn't have a say in government but then democracy
mandates they be allowed to vote. Education of even an insignificant
portion of them is hopeless. It looks like we may have reached some kind
of self-destruct limit.
The complexity of government has also outpaced the capacity of
99.99999% of the legislators and executives as well. This of itself
isn't a real problem - as in every other walk of life, the really
complex problems are dealt with obsessive-compulsive nerds, who
haven't got time for anything except maintaining their grasp of their
particular narrow field.

Part of the expertise of these nerds lies in recognising those aspects
of their problem area which are going to worry the general population
- and thus their bosses - and giving their bosses a suitably
over-simplified picture of the choices available, and the consequences
of these choices.

The real problems comes up when the bosses don't like the choices that
they have been given, and proceed to ignore the nerds who do know what
they are talking about and go shopping for pseudo-experts who will
offer them choices that they do like, and some sort of invented
justification for a course of action that isn't actualy going to have
the desired effect.

Dubbya's approach to global warming, tax cuts and the invasion of Irak
are three classic examples of this sort of self-indulgent ignorance,
and this is obvious to a lot more than 0.00001% of the population, who
all voted against him.

The rest of the voting population, who weren't interested enough to
work this out, shouldn't have been interested enough to vote.

Unfortunately, your sloppy electoral expenditure laws give campaigners
the chance to spend enormous amounts of money on TV advertising,
feeding the uninterested non-voter some vacuous line of twaddle aimed
at persuading them that Dubbya (or whoever) is a righteous God-fearing
person who deserves their vote. This gets to precisely the sort of
uncritical sucker who believes what they are told in TV ads.

If you improved your electoral expenditure laws to the point where the
politicians can't buy TV spots - which seem to be about the only way
of pushing a message into the face of the essentially uninterested
public - this uncritical bunch of non-thinking ciphers will stay at
home (where they belong) and leave the election to be decided by
people who are interested enough to go out and find out what is really
going on.

I was brought up with compulsory voting in Australia, and know about
the dismal consequences of forcing people to the ballot box - if your
name is at the top of the ballot in Australia, you've got a 2 to 3%
advantage over the other candidates due to the "donkey vote"

http://www.australianpolitics.com/elections/2001/sharp/01-10-21.shtml

I'm all for giving everybody the right to vote, but I want the people
who do vote to be interested enough in what they are voting for to
actively seek out information about the people they are voting for and
against.

TV spots aimed at the couch potatoes make life a bit too easy for
demagogues.

Subject: SHARK STEAMER FOR PCB'S ?
From: "Peter Kiproff" peter@microtrendrobotics.ca
Date: 11/19/2004 11:06 PM Central Standard Time
Message-id: <X8And.134$Pe3.278536@news20.bellglobal.com

I'm looking for another method to clean flux off of PCB's besides the
lacquer thinner & tooth brush way.

I understand some places use an industrial dish washer, without soap, just
hot water.

has anyone tried or herd of steam cleaning ? I'm thinking of those portable
steam cleaners like the " Shark "

this would be hotter, are there any draw backs with moisture ?

must I use water soluble flux ? what about rosin core ?

I assume proper drying is mandatory.
Hi, Peter. Your kitchen sink and hot water will do the job for boards soldered
with water soluble flux. These steam cleaners won't. And always use water
soluble flux for water cleaning. Rosin flux won't clean at all with water.

The drawbacks with water are mostly that you have to be careful which
components you put on the board before you wash, and which after. Some
components you might have problems with are pots, relays, connectors, &c. The
water gets in and stays in the components, or it can cause oxidation, or
residue from the cleaning process can gum up the works, or water/solvent can
mess up the lubricant on the part (switch/relay). These are just a few of the
delights awaiting the water washer. People find new ones all the time.

For real world boards, the decision is made early on in the board design what's
going to be done about cleaning, and component choices are made accordingly.
Or at least, that's the way it should be done.

Sometimmes you have to make compromises, and install, say, a relay or a pot
after cleaning has already been completed.

Industrial aqueous board cleaners have an air knife and a hot air cycle to help
get the boards dry. For home use, shaking the board after cleaning and rinsing
well in the sink, and then a trip thru the oven at 70C (warm) should be
sufficient. Obviously, you've got to get _all_ the water off, or it won't
work.

Also, do remember that most water soluble fluxes are toxic. Make very sure you
clean up well after you play in the sink or the dishwasher.

This link doesnt seem to like me.

I dont see how mere software can make the disk return 1 value from a
location which is currently 0. the disk doesnt have the mechanism or
the logic to read 'history' of a bit.

This process is accomplished externally, with very physical and
analogue techniques.

You may be confusing lost partitions/deleted files/stupid formats with
_overwrites_.

The disk is literally a long long string of 1's and 0's, which are
returned by the read head in the disk. It is this 'read function'
internally in the disk which reads a bit as a '1' or '0', and cant
tell you what it was previously. It is an external physical
interpretation of the actual bit itself which can reveal its previouse
value.

According to your reference mere software can not accomplish recovery
of an overwritten data bit.

One or two passes can be easily recovered by "error

• Read actual (digital) data
• Read raw analog signal
• Subtract expected signal due to data from actual analog signal
• Result is previous (overwritten) data

patterns (all 0's, all 1's, alternating 0's and 1's) is

The second type of scrubbing utility is used to clean drives that are
still in use. It leaves files intact so the computer stays
operational, but it cleans the ambient computer data storage areas by
repeatedly overwriting them in such a way that the original data they
contained cannot be recovered using data recovery or computer
forensics software. Among other things, this allows you
to be sure that the removable media you are using to transfer files
contains only the information you want.

By *overwrite* i do *not* mean 'format', 'repartition' or 'delete'.
overwrites can not be recovered by software alone. But can be done :).

150A regulator. He delivers his kW power level for only a few
seconds, and during that time dissipates 150A * 5V at most (likely
less, due to battery and cabling voltage drops), which amounts to
about 450 * 3 watt-sec = 1350J during that time. Unlike ordinary
linear kW supplies, this won't present a serious heat sink problem.

The TIP35 and TIP36 transistors are fairly cheap. I think I'd start
like this:

10 each TIP35
------------------- ---/\/\---
! \ /e !
! ----- !
! TIP36 ! !
+-/\/\/-- -----------/\/\------+
! e \ / !
! ------ !
! ! --------- !
---+--/\/\/\/--+-----! LM317 !---------+----
---------
!

Hmm, TIP35 transistors are not Darlington types, which means low
beta, but also lower Vbe. If each transistor conducts 15A with a
beta of 15, then the TIP36 PNP has to handle 10A, which it can do
just fine. If its gain is 25, the LM317 has to handle 0.5A, which
is also fine. At 500mA the LM317's dropout voltage is 1.7V, which
with a Vbe of 2V for a TIP36 at 10A gives us an overall regulator
dropout voltage of 3.7 volts Adding this to the 7.2V output tells
us the battery must stay above 10.9 volts for regulation at 150A.
If the transistor betas are a bit higher, and if the Vbe voltages
are a bit lower, the battery will be able to sag more, and there
may be room left for a cable drop. Now working the TIP35 pathway,
say the emitter resistors drop 0.2V and Vbe = 2V, this leaves 1.5
volts for the TIP36 Vce(sat), assuming a 10.9V battery. Everything
is working out, because 1.5 volts is what the TIP36 datasheet tells
us to expect for Vce(sat) at 10A.

So this is a viable approach, perhaps even better than my drawing.

Here's a small NPN power transistor spec comparison table. All
are big TO-218 style plastic packages, except the 2n6284 is TO-3
(rated Tj = 200C). The TIP35 and TIP36 are NOT Darlington types.

part thermal Hfe @ Ic Vbe @ Ic
number C/W Pd 10A 15A 10A 15A
------ --- --- ---- ---- ---- ----
TIP35 1.0 125W 30 >15 < 2V 2V (also PNP TIP36)
2n6284 1.09 160 750 500 < 2 2.5
BDW83C 0.96 130 750 >100 < 2.5 ?
TIP142 1.0 125 500 ? 2 ~ 2.5

All these transistors are inexpensive and widely available, but
they're comparatively wimpy. For example, a 2n5686 (see below) is
a 50A npn TO-3, rated at 300W, and it's much better suited for the
task, with higher beta and lower Vbe. But it's $11.76 at DigiKey.
The 60A MJ14002 is a bit less at $10.36 qty 10, stocked by DigiKey.

part thermal Hfe @ Ic Vbe @ Ic
number C/W Pd 10A 15A 10A 15A
------ ----- ---- ---- ---- ---- ----
2n5686 0.584 300W 70 50 0.85V 0.9V TO-3 non-Darlington
MJ14002 0.584 300W 100 70 0.8V 0.85V " "

Using one of these transistors would open the possibility of battery
voltages lower than 10.9V, although using a low-dropout LT1085, etc.,
instead of a LM317 (0.9V compared to 1.7V at 0.5A) would be required.
Then a 10V sagging battery + cable voltage could be allowed at 150A.

Hey, Tim! Very good tutorial. Thanks a million.
Mostly my personal biases, actually :).

Four additional points:

1. Any digital scope can get fooled by Nyquists theorem. Feed a 45MHz
signal into a 40Msample/s scope and you will probably see what looks like
5MHz signal. (Analog scopes in chopper mode can do similar things
but it's not exactly the same.)

2. If you've used a digital scope that you liked, go with it.

3. If you don't have access to any scope or much experience with
them at all, you will probably
be furthest ahead by getting a good old analog scope for less than a
few hundred $, even if not very impressive in terms of specsmanship.

4. You seem to have some ideas about glitch capturing, if you can be
more specific about what kinds of glitches you need to capture then I
think you can get some relevant advice here (and in sci.electronics.equipment).

My personal bias: I still like analog scopes. Even analog storage scopes.
I mutter to myself every time I have to walk through the menus of the
digital scopes that I use about how sucky their user interfaces are.
But for capturing multiple events etc. the digital ones have real advantages.

Tek makes one based on Windoz CE it is a real horror to set up.


The "user interface" problem with scopes started before they went fully
digital. As the front panels got smaller, the buttons and knobs got
smaller and had to become multiply fuctional. When things went digital,
they started from a bad user interface and made it worse. What we really
need is a larger front panel. Perhaps they could make it fold for
storage.

Hi, Tim -

At my last job, I used an HP54602B which I liked. But, it seems to be a bit
more than I can afford now that I'm retired.


3. If you don't have access to any scope or much experience with
them at all, you will probably

I actually have an HP 1741A that I use. Sometimes the trace won't appear for
about 15 minutes after power is applied. Both vertical amplifiers compress
the signal near the top of the display. And the stored trace will fade
and/or bloom after a few minutes of staring at it. (Isn't that a "feature"
of analog storage scopes?)


4. You seem to have some ideas about glitch capturing, if you can be
more specific about what kinds of glitches you need to capture then I

No, I have no glitch capturing ideas. I just thought it might be a nice
feature. I also thought it might be idicative of the scope's bandwidth. I
spent a lot of time not seeing spikes in switching power supplies because
the company wouldn't buy high speed scopes. I can remember scratching my
head over events that should have been on the screen, but weren't.

Tim.

I very much agree with your interface comments. I even like analog scopes.
What I don't like is the blooming stored trace (pun sort-of intended). The
main reason I want a digital scope is so I can store the trace in memory and
call it up a week later or as many times as I like without the trace
becoming unreadable.

The HP 54602B taught me that cursors and long-term storage were invaluable.
I had to develop a system that had a master uC talking to 50 or 60 other uCs
at 115200 bps on an RS485 bus. The only instruments available to me were the
scope and a desktop computer. With the scope, I was able to grab a section
of the packet and, using the storage and cursor features, verify that the
speed and data were as intended. After I got those problems worked out, I
used the PC to snoop on the bus and fix any other problems.

I also want a scope that can see sub-microsecond spikes for switcher power
supply development.

I bought and returned a Tek 468. I was not pleased with the quantization
noise I saw on the trace. I'm beginning to think it was a mistake to return
it. In light of what's available and the prices thereof, I could maybe learn
to work with the noise.

It looks like my desires and my pocketbook are incompatible.

Thanks again.

It really depends on who is doing the reading. If you are trying to
protect your data from anyone you know, anyone who posts here, any
known hacker, or any local law enforcement, you have no realistic
worries about anyone recovering your erased data. Worry instead about
burglary, search warrants, keyloggers, or just beating the information
out of you - all are far easier to accomplish. If, on the other hand,
you are a terrorist or spy trying to protect your data from a TLA
(Three letter Agency - FBI, CIA, NSA...) that has the full cooperation
of the drive manufacturer's hardware and firmware engineers, then you
have a lot to worry about. I have heard reports that the top terrorists
now avoid any use of computers, cellphones, etc., relying instead on
trusted human messengers. Good. The less capability they have the
better I like it.

He would like to program a atmel AT90S2343. Normally I write my own

What kind of format is this?
Motorola S Record.

I tried converting it to Intel Hex (which AVR Studio prefers) but
Studio 4 complained about it. Could be a conversion problem. The first
bit of it looks OK (the expected jump table) but I didn't try to go
too far with the hand-disassembly.

Isn't Quack missing?
You are mistaken.

This link doesnt seem to like me.

I dont see how mere software can make the disk return 1 value from a
location which is currently 0. the disk doesnt have the mechanism or
the logic to read 'history' of a bit.
There's no writing of zero when a file is deleted (unless programs like
Eraser have been used)... the file system just marks this area as free.

Previous context shows that the current conversation is limiyed to
actual overwrites, even if that is not specified in every post.
