On the other hand, I don't really like the idea of trying to claim a warranty when you know for a fact that you caused the damage.
I thought we didn't approve of that around here...


What we do recommend is relying on that when you have jailbroken, but something else non-JB related goes wrong -- it is safe to assume Amazon won't bother to check for a JB.
In fact, while we know they never examined the software for a JB (as a number of people can attest to based on successful returns) I don't know if they would overlook the physical signs of hardware modification.

That is a workmanship, warranty claim.
Regardless of what happened to it afterward.

It may be several days before I can get to it.

knc1, sorry for disturbing you - will you get some time to check your storage this week ?

Progress of a sort - - -
The above is just plain wrong. Sorry about that.

= = = =

The 'key' was that I could not reliably reproduce my own work.
Due to the wide variations I was getting - I suspected contamination.

It took me awhile to find it (plus I had to fit that into my available time).
It was the water I was using.
Everything else was 'reagent grade', EXCEPT for the water!

I was using 'distilled water' - which I thought would be 'good enough'.
Wrong, it isn't, at least not the jug(s) I picked up at the store*.

Which probably also explains all of the posted, differing, results on the 'net about any one specific echant combination.
Those differ because of non-reagent grade water.

= = = = =

"Reagent grade water on the cheap -"

Buy water marked as 'purified by reverse osmosis (ro)' -
read all of the fine print on the label to be sure that nothing (like fluoride) has been added.

You'll find that shelved with the other drinking waters.

= = = = =

With that error found - I should be able to test and correct my echant make-up.
All I need is free time.

= = = = =

I would still like to (someday) make a serial-USB converter that fits inside of the Kindle case.
I have gathered (I think) everything I need (once I get past the echant speed bump) but that will take a lot of time.

I decided to first make the adapter mount on the back of the Kindle.
Which will require (after setting options and connecting wire leads) some potting and gluing.

Potting -
I also have a solar cell project in the works, which will need potting.

I would like to improve on my micro-photographic set-up for documenting these tiny parts and connections.

Ah, so - a single answer to all three requirements.
Sylgard 184 from Dow Corning:

Or, the very similar, Qsil from QSI.

Both available from Amazon (who else?):

http://www.amazon.com/gp/product/B005RYI7C2?psc=1&redirect=true&ref_=oh_aui_detailp age_o01_s00

= = = =

It should be obvious that solves the potting of a serial adapter, and the sealing of a solar cell array -
But how does it help with the micro-photography?

You can make lens with it (a similar product is used to make contact lenses).
http://www.osa.org/en-us/about_osa/n..._droplet_lens/

Then add that extra lens to your cell phone or tablet camera.

Steve Lee's original paper is attached.

(*) There are a lot of things which distillation can not remove from water.
Agent Orange is one of them, there are tens of thosands of veterans that can tell you about that one.
