Why .30 cal holes can't be seen at 800 yds...
Well, I really have not contributed much if anything to this thread, and
this will be no exception. However, it does remind me of my youth and
specifically of some of my non electronics related activities. Of course,
what I am about to disclose below, today would label me a terrorist.
In the late 50's and early 60's besides electronics, a bunch of my friends
and I were also interested in explosives and the reactions that various
chemical combinations could bring. All of the required ingredients were
available in any drug store, off the shelf. None of our interests had to do
with actually creating havoc, or harm, but just the ability to do them. The
now censored "The Anarchist Cookbook" is a joke compared to what we used to
improvise, and, no one ever got hurt.
What triggered me to respond to this post was the explosion upon impact
statement. I devised a very unique, at the time, device that worked just the
way I wanted. I had a pump action .22 caliber air pistol, on which I made a
mount to place a rifle scope. It was awesome. Anyway, the .22 pellets were
hollow, so, inside, in the very front, I place the tip of a self igniting
match and followed it with gunpowder. Gunpowder of course was readily
available either from bullets (shot gun) or I just made it. Then I epoxied
the end to seal it. Overnight they were ready to go. Real neat. When shot,
upon impact, they of course would explode. Since at the time I was
considered one of the "brains" at high school, and all my teachers were my
buddies, they had no objection to me having this pistol in my briefcase at
school. Heck, I even was a baby sitter for a lot of their kids, and, of
course, I repaired their broken TVs and radios. I even helped one build a
house. The last several years of HS, a lot of my teachers signed my yearbook
as "To 007". I still have those yearbooks, and the best is the one where one
teacher signed it "To 007 - From Dr. No."
I better save the more volatile experiments and adventures for another time,
as this has nothing to do with time-nuts, other than to prove that besides
time, we are all kind of nuts. Regards - Mike

Group,
I haven't been following this thread that won't die, but I've
contributed to others :^)
If the problem is that it is expensive to detect when a bullet
hits a target half a mile away, then have I got a solution for
you!
Visit any friendly neighborhood terrorist supply store and buy
a small quantity of PETN, or any other explosive that can be
detonated by the impact of a bullet. Smear a coating of this
over the area of the target that you intend to hit.
When you hit the target, there will be a very bright flash
with a very fast propagation velocity, which should be adequate
for the average 10X scope and photosensor.
No, I don't know where to find a terrorist supply store. Perhaps
you can make do with the PETN in blasting caps, or brew up a
batch of nitrogen tri-iodide, as any college freshman could do
in the fifties. Or try the powders from a Very pistol flare.
Yours for more creative solutions,

Other wise you may loose some time.

There's always nitroglycerin. I've heard it reacts well to vibration.

Hi Time nuts,
Just recently started my Z3801 in my new location and noticed the following discrepancy....
The unit is running more then 145 Hrs from the new start up.....and the "life time" display from the starting time just shows 48 " digit" more time......in other words:
started at life time 13917 and after 145Hrs it shows 13965......
what is the meaning of the "life time" display / windows/.....
Please advise.
Many thanks ,
Ernie.

I can't find it in the manual but I read somewhere that each tic of the
lifetime counter is 3 hours.

Hi
It is in odd units. It's also sort of a meaningless number. There is no obvious wear out mechanism in a Z3801. If anything they should get better the longer they are on power.

I never saw the original message because, apparently, it was off-topic
posted in one of the noisy threads I was deleting. But anyway...
From the similar GPS 58503B manual:
:DIAGnostic:LIFetime:COUNt? RESPONSE
Returns the lifetime count, indicating the total powered-on time.
Range of the integer is 0 to 4,294,967,296 with a resolution of 1. Each
count
represents three hours of operation.
If I did the math right, that allows for about 490,000 years. Probably a
bit more than necessary.
The OP said,
"started at life time 13917 and after 145Hrs it shows 13965"
So that would be 13965 - 13917 = 48 x3 = 144 hrs
13965 x 3 = 41860 or about 4 3/4 years of on time.
