P.S.: Does it seems so or I am imagining things, or read something like that but it appears to me there is more noise and less frequent calibrations of the image after installing the menu hack?
"running lines" down the screen, pixel walking... vertical stripes holding on place...
how do I check actual Noise setting applied in my conf
IIRC I have read some reports on the 2.3.x menu upgrade suggesting that it has an effect on the cameras OS speed of response.
If the processor resources are being overtaxed it may have a detrimental effect on the image processing algorithms and the cameras overall stability.
Some features did not work and caused instability in the camera. IIRC these were relating to Delta T and Humidity.
My camera is very stable.
Hmmm,
just playing with my converted E4 looking out of my window at people passing by (I live on 8th floor so it is observation from 20 meters height, at the distance over 50 meters away). It was early evening and surrounding temperature was 25.
I was expecting to see walking bodies glowing white in Iron palette(assuming these are not zombies) as I believed their temperature is well above 30C. But they didn't glow white! Then, I used 'color above threshold' palette so they should appear red, while the surroundings should remain gray.
I was surprised to see that all people in my area are actually zombies, because they didn't trigger the threshold anyway... they were of course not naked, but close to that at such temperature, but they appeared only slightly warmer than surroundings, so I had to set the threshold to 25.5 before they started to emerge red in grey.
At this distance, a typical figure of man is 12 to 16 pixels high, 6 to 8 pixels wide. Quite enough I would say for successful detection. Meanwhile, my own body, although observed from 10 meters in mirror, shows 35.4 C and 36.6 with the camera at the closest possible point.
Question: are they really zombies or something is wrong with measuring distant objects temperature? 50 meters are clearly not enough for factors like humidity come into play.
P.S> I expected that even a single pixel measurement will trigger the threshold, no matter how cold the surrounding pixels are... but now I assume some interpolation or statistics is applied to a group of pixels and, basically, it results in some limiting gradient value along the chosen direction or what?
@all,
@Mike
I also would like to re-trigger the topic about empty slots on the E4 motherboard. It is over 2,5 years from the first Mike's teardown post and we still have no idea, which IC is on the E8 board soldered in this empty slot?!! As far as I can understand, once we know what the IC is there, we can solder it in and, have wi-fi and Bluetooth enabled?
hi Mike,
thanks for quick response,
but really, why is that empty slot there? I though it is populated on E8! Have you actually a chance to look inside E8? Or maybe anyone you know who did?
I bet, this motherboard is not a replica from EX0 so, even if this slot is unpopulated it might be 'reserved' for future functionality, or it might be the original design allowed for Bluetooth and wi-fi but then, due to marketing reasons they decided not to interfere with EX0 model range and thus left it unpopulated.... much likely it was a decision made already after the design was made and the motherboards were printed in bulk quantities... as it happens with marketing often last minute decision...
This could mean that if we only knew the IC which is in the EX0 responsible for the functionality, it should fit the unpopulated slot and work, if the drivers are provided (if not already there as plug-n-play option).
Anyway, thanks!
Btw, Mike, since you are here...
Do you still have your old original E4?
