content: Interesting film.My Dad worked on the F1-11 here in Australia, they had an issue with he TFR near Townsville, where the continental shelf is has a very shallow angle.When flying from land over the ocean, if the salinity and ocean temperature were just right, the TFR would not see the water and fly into the ocean if not corrected, following the ocean bed. This sort of thing was alluded to late in the film.

I contacted Kodak HQ for advice and within 2 daysI got an email reply with advice on how to proceed with developing it. Unfortunately in my case the film proved to be entirely fogged but I sure found ita very special experience.

content: This sort of thing is fascinating, I wonder how much more usable undeveloped film is out there and what all is on it.While not undeveloped, while cleaning out my late grandparents home a while back I found a box of color slides my grandpa brought back from WWII along with a yellowed list handwritten in German of the contents. They had apparently belonged to a German officer and contain a variety of scenes from rather dull landscapes to pictures of soldiers relaxing, some of tanks, trucks and planes. Pretty fascinating, I have no idea how my grandpa ended up with them, I didn't even know he was in the army until well after he died, he never talked about it when I was a kid.

Viewing HDMI bit error rates? - Page 1

author: Delta
author_rank: Super Contributor
timestamp: February 10, 2017, 10:32:21 am
content: Following on from the speaker cable thread.....Given that all HDMI receivers apply FEC, they must internally "know" the BER, but is it possible to view this figure?Are there any consumer devices or modules that allow such a thing?This would allow a completely objective yet 100% real-world comparison of cables.

author: Halcyon
author_rank: Unknown
timestamp: February 10, 2017, 10:38:17 am
content: My Philips TV has a "status" button that shows HDMI signal "strength" including BER on-screen. Not sure how common that is with other devices? I find however, there is always some error. It depends on the device transmitting, resolution and cable length. While one particular lead might have low BER @ standard definition, it increases significantly at full HD.

timestamp: February 10, 2017, 10:42:17 am
content: Its rare to see any monitoring of BER. In fact, its rare to get anything more than the most basic information out of a TV about the HDMI signals - like if the interface has negotiated 4:4:4, or something poorer.

timestamp: February 10, 2017, 11:04:43 am
content: There are several layers of error correction on the control and audio data and they are transmitted with different coding, but there is effectively no error correction possible on the video data. So the error rate that is detectable by a sink is not a good measure of the total BER.

content: Batteries are getting surprisingly cheap nowadays. Around $200/kWh in hobbyist quantities, even less in bulk. About a kWh or two would be reasonable to carry in a backpack, substantially more in a box on wheels. Pretty reasonable to get a few hours of runtime by means of an external battery pack. And don't forget that a good part of the 780W might in fact be to fast charge the battery, so the system itself would likely use less. A "portable supercomputer" wouldn't exactly be travel friendly anyways.

Vizio smartTV wack for 2.2m for collecting info w/o consent - Page 1

content: Vizio, one of the world's biggest makers of Smart TVs, is paying $2.2 million to settle chargesthat it collected viewing habits from 11 million devices without the knowledge or consent of the people watching them.According to a complaint filed Monday by the US Federal Trade Commission, Internet-connected TVs from Vizio contained ACR—short for automated content recognition—software. Without asking for permission, the ACR code captured second-by-second information about the video the TVs displayed. The software collected other personal information and transmitted it, along with the viewing data, to servers controlled by the manufacturer. Vizio then sold the data to unnamed third-parties for purposes of audience measurement, analysis, and tracking.For full article:https://arstechnica.com/tech-policy/2017/02/vizio-smart-tvs-tracked-viewers-around-the-clock-without-consent/

content: This is why you either don't connect your "smart" devices to the internet, or if you must, restrict what they can access through a firewall. It also pays to think about all the devices you own with cameras and/or microphones in them; Do they need to access the internet for anything other than software updates?? Probably not.For example, I'm a huge fan of Sonos products but the Play:5 speaker has a built-in microphone (for "auto configuring" the sound set up). I for one don't trust Sonos to keep their firmware totally secure (or their products not to be exploited) so the firewall blocks anything but the radio stations I listen to.

Some other common items appear black but are transparent to IR. You can use a IR remote control and digital camera to examine the characteristics of likely candidates.

I have two options:1) Find an old stock of these devices (either X24C44PM, X24C44DM or X24C44SM). The only supplier that I managed to find is from Hong Kong and I believe these are counterfeit devices.2) Find a similar device with the same pinouts (may not have the same pin orientation as I can implement an adapter)I need these in military specs since they will be operating at high temperatures. Currently I am using the standard (commercial) package which is not able to withstand these high temperatures.Please can anyone help me find a reliable supplier or an alternative device which would work with minor changes.Any kind on help would be highly appreciated.

content: What about the plastic fails it from high temperature use at 125C. The mil spec units were typically the same devices, just with a 125C burn in for a time (48 hours IIRC) to weed out infant mortality, and then a few fast cycles from -55 to 125C followed by another test cycle. They were normally just the regular devices off the line, with a certificate so you could ( like with the regular devices) trace them back to the die they came from, and have the record of processing and incoming material samples and tests.No difference processing or packaging aside from the extra testing. Regular IC production has for decades been capable of the mil test with no problems aside from some very high density chips that will fail over 70C in normal use, or with the fast cycling. These chips also fail in use at a high rate as well, they just are in use in equipment with a 2 year design life.

The part number is too vague and there doesn't seem to be a manufacturer mark (unless it's the very plain "F"?). The only lead I have is they were mixed in with a bunch of 7400-series logic chips but that doesn't necessarily mean anything either... and I'm fairly certain it's notPokemon related.Would anyone have a clue what it might be, or have some tips for searching?

Strange doorknob spring mechanism - Page 1

content: This is more mechanical engineering than electrical engineering, but, heck, they are similar enough.So my house is fairly old, around 100 years, which is typical for this area (Schenectady, former home of GE), and the knobs are all probably original in the downstairs floor.Well, one of the knobs broke in a sort. While normally the latch has a spring behind it so it can push out (In order to close the door), it wasn't doing that right. Instead itcould only be convinced to move out just enough to close the door with a lot of fiddling with the knob. You can't push it closed, which is the bottom line.So I open the lock up, and I find that instead of a single spring, which I thought might have been dislodged, it's two springs, but not in separate locations, the intendeddesign for that knob/lock (Warded lock) is that the two springs are right next to each other, essentially forming a longer spring, and one of the springs had turned on itsside and didn't spring all the way. Why they didn't just use one long spring, I don't know (And I am interested if there is a reason) but I finally righted it, and it works alrightnow.
