It "looked good" for me up to 100Hz after Nyquist in the spectrum but didn't pull any precise data. Just created a 50Hz tone using my speakers which showed up in the spectrum after…

Sadly you have to install the codecs from external sites. This - at least for me - messes up the rolling release stuff at least one a month.

Honestly: don't know. My experiments never had a dependency on linearity.

Theoretically wind can be Nulled with a 4-way water splitter that are placed in 90° angles (+ a connector at the bottom to the sensor). As long they are orthogonal the wind pressur…

The Sensirion SDP600-25Pa speaks I2C and only has a handful of primitive commands. Add this and 3.3V and you are done. I'm 99.5% sure if you throw Claude with a datasheet on it wil…

Not much circuits needed. The SDP600-25Pa speaks I2C and only has a handful of commands. Just read it out with a microcontroller you love (like ESP32) and send the samples to a hos…

Yes. But they usually are not performing very good between 1-250Hz. Sensirion is using a thermal flow-sensing principle method which is basically a heated plate that cools/heats up…

If these Shahed drones have a propeller they should have a brutal signature between 0-250Hz as they are moving a lot of air. And if the engine speed of the Shahed stays constant it…

They are getting better. After a long time they introduced ONVIF into their camera products which basically opened it to everyone.

And screaming loud Keygen music

I just wait until a Opensource model inhaled all the chemistry books and papers. Lol. They are following closely and the best offer 80-90% of the performance and come with a very s…

Freshly marinated in DEET

With Wi-Fi 8 we will finally get steerable friendly roaming like cellular radio is doing for almost 40 years now. This "here's a neighbor table, disassoc and fuck you&good luck"-me…

For sensor stuff use LoRaWAN + Mirotik Basestation + Chirpstack

All ham radio repeater groups here dropped Meshtastic as it was super unreliable. And they know how to build proper antennas and filters. Meshcore is 100% free. The last issue was …

With GNSS+PPS and a hardware timer latch you can easily sync internal microcontroller timers to 2 to 3-digits nanoseconds against the global standard with a tightly controlled loop…

The NICs need supported hardware timestamping. Then they can be used with ptp4l. Intel i210 and i226 does this. But the i226 has a few variants.

Reminds me a bit of the research dept of the company I'm working for. If they have too much free time they put much weirdo stuff into their devices just to see what.. happens. They…

Interesting. In safety components we are using Lockstep Microcontrollers which are doing something similar in a much smaller scale. https://en.wikipedia.org/wiki/Lockstep_(computin…

Gitea Upgrading.. replacing binary, restarting. I love it. Same for Forgejo.

> Wifi HaLow 802.11ah LoRa is another level. It works down to -146dBm. 802.11ah dies around -100dBm. Still much much better than "standard" Wifi. But you are comparing two differen…

If you want to build sensor stuff you should have a look a LoRaWAN. Get a basestation from Mikrotik and use Chirpstack as backend. This setup is commercially very very battlefield …
