My favorite offtopic thread

It's interesting that you don't feel the cold when you do it on the regular basis. On the contrary, body temperature jumps to 38+ immediatelly after man gets out of such "pool"... This happens due to latency of thermoregulation system.

What quantum source do you use?

What quantum source do you use?

Four old lantern mantles. According to my estimation four mantles contain ~ 0.41g of thorium-232.

Look awesome.
How do you sample the noise?
Is that a couple of old Geiger counters you use? 

[Balthazar]

How do you sample the noise?

if t3 - t2 > t2 - t1 then we have 0
if t3 - t2 < t2 - t1 then we have 1

Where t3, t2 and t1 are timestamps for last three particles.

Even with small subset the results are almost identical to ideal noise:

Code:

Entropy = 7.999598 bits per byte.

Optimum compression would reduce the size
of this 459800 byte file by 0 percent.

Chi square distribution for 459800 samples is 257.03, and randomly
would exceed this value 50.00 percent of the times.

Arithmetic mean value of data bytes is 127.6948 (127.5 = random).
Monte Carlo value for Pi is 3.141414273 (error 0.01 percent).
Serial correlation coefficient is -0.000750 (totally uncorrelated = 0.0).

Is that a couple of old Geiger counters you use?  

Yep, a pair of SBM-20 geiger counters is used to count the particles.

I would drink her bath water

Really? In Russia, mothers and daughters share the same bath water. Here's a pic of her mother:



Here's the bath water:



Get to drinkin'!

BTW, the mothers bathe first, so if you have any vision of eating anything...

Maybe I missed a bit, but I think you're talking about Ukraine.

In Ukraine, they shower. That's why Putin is showing so much interest in it.

[carlosiness]

hahaha, there are a lot of funny pics from russia, especially, these guys with stupid hats and tracksuit with three or much more lines

Too bad they can't afford hot water.

Course of the day for Ukraine nazis and their western fascist sponsors

Very nice project. 2 x Thumbs up.
If I had more free time, this would def be my next project.

[Balthazar]

Radiation is the only issue, each pair of mantles emits ~ 25 uSv/h... Not a problem for me but my gf thinks that I'm crazy...



Thinking about proper shielding of the device. 1mm of aluminium should be enough.  

P.S.

Code:

pi@raspberrypi ~/bmp $ dd if=out.bin bs=1024 count=64 of=random.bin
64+0 records in
64+0 records out
65536 bytes (66 kB) copied, 0.0039159 s, 16.7 MB/s
pi@raspberrypi ~/bmp $ cat random.bin | convert -depth 8 -size 320x200+0 gray:- out.png
convert.im6: unexpected end-of-file `-': No such file or directory @ error/gray.c/ReadGRAYImage/207.

^ My type of model. I'd hit it!

She will have a few gifts that will keep on giving for years.

my gf

pix plz

[TookDk]

my gf

pix plz

LOL - That was a good one  

...

...

so... ...  .... where are they? (the gf pics)
