I did include a picture of the capacitor. Maybe some not-so-AI thought it was a bomb.

Google does seem to be using artificial intelligence a lot. Your posts on the thread mentioned 0.45 calibre bullets as examples of the quantity of stored energy you were dealing with. It's not one I've ever seen any other electronic professional use. It might have been enough to trigger its anxieties.

Somebody else suggested that a pitched baseball was in the same ballpark. A much less threatening example

Can't be too careful nowadays....could be a disguise for a p... b... LOL

I don't use gmail unless I want an address in public. Since email started I have preferred to run my own email server. For the type of email you're sending I'd probably use this:

A man at Dublin-City University posted to a DIY-explosives USENET newsgroup decades ago complaining that persons who contribute to that newsgroup are dangerous because e.g. the Irish Republican Army could study that newsgroup to learn to make bombs. A consequence is Dublin-City University disabled USENET accesses between the USENET and most persons in this fake university.

"PC Format" (a magazine by Future Publishing) in the United Kingdom of Great Britain and Northern Ireland called programmers for an American Internet-service provider idiots because this ISP blocked emails about Scunthorpe (a place in the U.K.) because a substring of "Scunthorpe" is a word which they do not want clients to read.

A fool got 110/110 (i.e. 100%) in a degree in physics. He sent myself an email via GMail. He requested me to not publish it. Even though I had never logged into GMail, I had responded to him indicating that Google advertising might be based on scanning this email. It is poetic that physicist rhymes with fool. (S.

Just don't use Google for anything serious, especially email. Assume disposable resource that could go down at an time. They also don't like compressed, or binary files and have limits on attachment sizes. Junk, consumer quality service, even if it is free.

Pay a bit more for something that works.

But the bullet will be much noisier.

I use Outlook because my company does. No problems sending to co-workers.

I sent emails to some google addresses and those bounced.

I used to like Thunderbird, but my company went all-Microsoft.

virgin.net had a similar issue.

Of course it will. It depends on converting a solid lump of some nitro-carbon chemical into hot gas, and that's bound to create a supersonic shock wave.

Your capacitors need add-on goodies to create the supersonic shock wave.

I just paid the IEEE $US44 to maintain my IEEE e-mail address. It used to be covered by my membership which has been free since I became a life member. I've got my own e-mail address tied to my web-site, but it doesn't go back as far.
