There is another reason why (especially cheap/"normal") thermal cameras have low frame rates. Basically higher (than 9!) fps cameras can be restricted for export and travel under ITAR (International Traffic in Arms Regulation

Probably yes, as it means less actual sensor surface, so it's a tradeoff between better focus and noise. But it's hard to quantify without comparing electrical signals.

You don't have to think about the physical image sensors as just an array of sensors with 1:1 correspondence in the final picture. There was always a lot of computation in between - bayer filters with more green pixels, different grid

Skydio doesn't have anything in the EU hot market (under 250 grams; over that weight you have limitations). If you do not trust DJI you can just use a different application to fly the drone instead of DJI Fly; Litchi is the best I thin

I had issues with 10G copper SFP+ modules even when there was only one installed in the switch (Mikrotik CRS305-1G-4S+IN), the other modules installed being DAC/fiber. I got random disconnects I could not attribute until I checked the

They are made to be good enough without costing a lot (some Noctua coolers are more expensive than a whole CPU) and usually address only the lower-level enduser market, where a difference of $5 can be an important percentage of the price. B

I did almost all the same upgrades to my T430 around 2014, with small variations (BIOS reflash with hardware programmer instead of software workaround for wifi upgrade, as at that point no workarounds existed). I used it for more than 2 yea

I remember encountering something similar in the Lamborghini Sian kit - I think around one of the diffs; I left the axle a bit loose just in case, and that was good, because of course I mounted the diff the other way around and had to take

That is very old information and not up to date (newest laptop in that list is 14 years old). Resetting a BIOS password for newer models requires a bit of voodoo (booting up with what looks like a debug BIOS to retrieve info from somewhere

Nice project! I did almost the same (Garmin v3 Lidar + steppers), but based on an ESP32 instead of raspi + arduino. The problem I have is the scanning speed vs resolution. The sensor is quite slow, so it takes a really long time to scan any

They do have a lot of advantages: a flat country, good infrastructure for cycling, cool climate. That means you don't sweat on the way to work so you don't need showers and to change clothes.

That was a political decision. Having your own grid means that you also have your own power frequency regulation, and importing power from a different network is not as simple as connecting wires - you need to connect them using DC instead

There was no need for KGB to steal everything, as they already had good optics; the Zeiss factories were moved to Russian-controlled teritories during the Second World War[1], including workers. [1] http://www.novacon.com.br&#x2F

Glossy screens look better in ideal conditions. The matte screen diffuses the light (that's how matte works) a bit and reduces the contrast and it looks a bit blurry. On phones, capacitive screens use a glass layer. Apple extended the

I remember stumbling on this page in 2003-2004. When I saw the title here I thought 'I hope it's the same' - and it is! It looks exactly like it was back then[1]. Love it! [1] https://web.archive.org/web/

The talk about striping (the fact that all the disks contain both data and the two levels of parity) is glossed over, but what it means is that there are not 7 types of failure/recovery, there are just two - when one drive fails, and w

Lenovo P53 has 3 NVMe slots, 4k OLED with touchscreen (and optional pen) and up to 128GB ECC RAM if you choose the Xeon processor. It's big and heavy, but it exists. I hope AMD will create a better market for the ECC laptop memory (rig

It depends on the sensor size. 16mm in this case is not the 35mm-equivalent.

The easiest way to test printing at an angle is to rotate the object 45 degrees before printing; you'll need a lot more supports, but it can be done. The results depend on the forces your object will see. The tensile strength is lower

They work exactly the same as a screen. Orange is not pure red, it is red + yellow, and yellow is red + green. So orange is red + _some_ green. The in-camera processing will render the image based on the sensor input and the known propertie
