For diodes, you might try BY8418 which in the UK is part 663-815 from Farnell, and costs less than a can of Coke, rated at 18kV. While you're at it they sell 15kV capacitors but these cost more, or you could make your own capacitors from foil and plastic sheets if you prefer.
From what I remember the lighters have a little spring loaded hammer which must produce pretty large forces on the piezo material.

I don't know if your calculator is busted or what. Last time I looked,
10 X 100,000 is 1,000,000. That is 1 million -or- 1 megohm... not 1 Gigohm. 1 Gigohm is 1000 Megohms -or- 1000 X 100,000. 1 Gigohm is 1 billion ohms.When you multiply "10s", all you have to do is add up the zeros from each factor and you have your "powers of 10".

You had best be going back up above and rereading what's there. It's _not_ 100,000. It says 100,000k ^ Big difference! And it's not a typo, 'cause it says that value _twice_!!
And as for your statement above - I quote "> 1 Gigohm is 1000 Megohms -or- 1000 X 100,000." You had better review that one, too!

Yes, I sure screwed up for certain. Kause I missed it big time.
But... 1000 Megohms is 1 Gigohm, though... is it not? Doesn't Giga=billion?
Did I goof there too? :\

Don't sweat it! We all do it. I always argue I'm so learned(*) BECAUSE I've made so many stupid mistakes.
(*) Some will certainly argue that point ;-)

ALL steps are in multiples of 1000
Just like capacitors are in steps of 1000
1.0 = 1 1.0k = 1,000 1.0M = 1,000,000 1.0G = 1,000,000,000Since I see you do catch the "a" occasionally why do you leave it out at times? It is Megaohm, not Megohm. It is Gigabyte and Gigaohm, not Gigohm. "Meg" and "Gig" are not valid prefixes. Perhaps... only in conversation.

I guess I really goofed now... here I thought this was an electronics group and now I find out it is really an English grammer and spelling group.
My bad. :(
P.S. Why do I leave the "a" out at times?? Because this is recreational typing and it really doesn't matter all that much, in here.
Everyone knows what I meant. Even you.
Perhaps you have a need to feel superior. Well, it looks as though you are.
Thanks for noticing, though.
I read in alt.binaries.schematics.electronic that buck rojerz wrote (in ) about 'PiezoElectric Spark Ignitor', on Tue, 13 Sep 2005:
I believe the 'a' SHOULD be left out, for euphony. I see no reason, except pedantry, to slavishly preserve the whole prefix when it results in the vowel combination 'ao'.

I agree about the spoken form, but disagree about the written form.
We will have to ask IEC TC25 for an official ruling. Expect the answer later this century. Much later.
Kibis, anyone?

Exactly. Which I believe I mentioned.
Ok, guys I mistyped twice, that 100,000k is wrong it should be 100,000 or 100k. Someone could have wrote about the idea, in support or against rather than blathering about the error!

I believe this IS just conversation. Certainly nothing like formal writing, where I would admittedly... "fail miserably".
Well put, Mike. Thanks
The "k" adds 3 more zeros. "k" standing for thousand.
100,000k = 100,000,000So 10 x 100,000k ohms = 1,000,000,000 ohms = 1000 megAohms = 1 GigAohm

I HOPE that's right. I'm a little gun shy, at this point. :\

I believe the authoritative source for this info in the U.S. is NIST, which is in agreement with the rest of the world. Go here, and after brushing up on the prefixes (and while there, brush up on the prefixes for binary multiples, last paragraph), go to Rules and Style Conventions.
