Having just gone through the tedious process of collecting all the
pieces necessary to make a capacitive fuel tank sensor that doesn't
work, I would HAPPILY pay $35 to have all the pieces collected
together. There would be some comfort in knowing that someone has
done the difficult work of verifying that all the parts are present,
the tolerances work out, and the circuit has some hope of working. I
bet I spent over 4 hours ordering less than 50 pieces. Digikey put
each in an indiviual box and then put them all in a really large box.
My $20 worth of pieces ended up costing me $35 once the shipping was
added in. A $.04 resistor only cost $.04 when you buy a roll.

I also made my own circuit board. It was a fun exercise, but time
consuming. Once I learned the circuit layout package, etched a board,
discovered all my errors (it's not always obvious which side a trace
MUST be on), etched two more iterations...I've got dozens of hours
tied up. I'm sure I'll be able to make circuits with this method in
the future. It's fun and rewarding. But if someone has a board
avaible for around $20, it's hard to justify the effort.

Me too! I have just paid for such a beast, i.e. a battery desulfinator.

I can do lots of things, but understanding electronics is not one of them.

I do know which end of a soldering iron to hold, and if someone tells me to
put tab a into hole b and apply solder, I can do that.

So yes, gather everything, and give a good set of instructions, and it would
be "more better."

Battery desulfinator, eh?

Can hardly wait for the hard core testimonies
concerning all the batteries that have been
undisputedly desulfated & resurrected...

Like me from Muzzleloader.

Ahhh, I don't think so.

Desulfinating battery plates are a simple matter of science.

Raising you from the dead was a miracle....I think.

Is it right to call a mistaken action, a miracle? g

Not to call you a mistake, mind you! :-)

Oh ****!

When science is reduced so cavalierly as to be a"SIMPLE MATTER"....
one of two things usually rings true.

Either one is a bona fide chemical/electronics expert or...
one could not be more ignorant or legendary in their own mind.

To identify which class prevails here, please articulate
this dirt "simple science" for the uneducated masses.

Also....
1. How much experience do you have"desulfinating"?
2. Please describe your DESULFINATOR in some detail.

Have you read Jim Weir's SULFATE BUSTER article....

P.S.
My success resuscitating lead acid batteries is 'spotty' at best.
The investment in time, effort, materials and money spent replacing
'holey clothes' has convinced me to BE PRACTICAL and just limit my
input to TLC until a faithful battery has died a natural death....
then, just 'SIMPLY' replace it. :-)

Your mileage may vary.

First, let me say that it was "simple" was partially a poke at comparing the
complexity of doing something like raising a former ag pilot from the dead.

I have no great hope of getting long dead batteries working again, or
getting batteries to live twice as long as they would be expected to live,
or any other miracles of those types.

It would be nice to keep the batteries performing a little better in the
waning months of their lives. I have a lawn mower with a battery that
always seem to die early, and I hope I could get it to live longer.

Any other benefits I get from it will be gravy. It was cheap, and something
else to fiddle with. End of story, on my motivations for getting it.

Long ago, my college job involved large battery powered pallet movers. They
would be overcharged occasionally, or acid was somehow spilled on the
outside of the machine, and would then dry up. If one were to brush up
against one of these machines, and transfer some of the crystal acid onto
their clothes, it would not be noticeable, immediately.

When the clothes got washed, the acid was re-animated by the washer, and
would come out a mere shell of their former shape. :-)

Those of us that were there know it was a miracle. After Bob rose from the dead
he broke bread with us and pontificated on various subjects in a wonderous
manner :-)

Apostle of Mercy: Saint Faustina Kowalska, 1905–1938

(From Wiki)
"Maria Faustina Kowalska, commonly known at St. Faustina, born Helena
Kowalska (August 25, 1905, Glogowiec, Poland – October 5, 1938, Kraków,
Poland) was a Polish nun and mystic, now venerated in the Roman Catholic
Church as a saint."

http://www.thedivinemercy.org/message/stfaustina/
"Though the Divine Mercy message is not new to the teachings of the Church,
Sr. Faustina's Diary sparked a great movement, and a strong and significant
focus on the mercy of Christ. Pope John Paul II canonized Sr. Faustina in
2000 making her the "first saint of the new millennium." Speaking of Sr.
Faustina and the importance of the message contained in her Diary, the Pope
call her "the great apostle of Divine Mercy in our time."
