🇵🇱 Jakub Kulik – bohater pochodzi z Bielska-Białej. Nasz druh. Nasz policjant.
Wczoraj w Krakowie, na Rynku, dwóch policjantów stanęło oko w oko z uzbrojonym napastnikiem. Nie mieli karabinu, hełmu ani kamizelki kuloodpornej. Mieli tylko służbowe pistolety i coś, czego nie da się wydać rozkazem – odwagę.
Jednym z nich był starszy posterunkowy Jakub Kulik.
Facet z Bielska-Białej. Były żołnierz 6. Brygady Powietrznodesantowej. Druh OSP Leszczyny.
Dostał kilka postrzałów. Ma niesprawne jedno płuco. Walczy o życie 😞
Patrzę na to zdjęcie – młody chłopak w mundurze strażackim, z podpisem „dh Kulik Jakub” – i myślę, że właśnie tacy ludzie noszą ten mundur. Nie dla lajków. Nie dla awansów. Dla innych.
Cała Polska powinna dziś trzymać za niego kciuki.
A kto może – niech odda krew grupy AB Rh+, zaznaczając, że dla Jakuba Kulika.
Wracaj do zdrowia, druhu.
Wracaj do zdrowia, policjancie.
Jesteśmy z Tobą.
Cześć i chwała Bohaterom. 🇵🇱

Life goal achieved: visiting NIST-F4, the US's current primary frequency standard. I learned SO MUCH I didn't know about how UTC(NIST) is generated and distributed. I can't wait to share it in a video!
(Thanks to everyone at NIST who answered my time-noob questions!)

9/ Summary
Every family should have a set of Baofeng or other FRS/GMRS radios for any kind of disaster. During #HurricaneBeryl we lost cell and Internet service for 6 days so the only way to chat was via radio.
Buy your radios NOW. Charge them and PRACTICE with them. Radio is not something you pull out of the closet after the balloon goes up.
Practice monthly.

8/ So, you want to get a message to Grandma in Chicago and you're in Houston, Texas and the grid is down. One way is to get the message to a Ham radio operator who can relay the message to another station who can relay it to Chicago.

A very short thread on the Baofeng Radios for normal humans.
🧵
1/ Your handheld radio in Texas is not going to let you talk to Grandma in Chicago. It will let you talk to folks in very short to intermediate distances. There are several FCC-defined services.

Save money on not buying a weather station. Buy an SDR and get the data from a neighbour 😃

Most interesting heatsink I've seen in a while. Found it while performing a Noctua fan swap on my Calnex Rb/GPS Frequency Reference. It's more like a porcupine than a heat sink!

I highly recommend cloudflare's security audit skill: github.com/cloudflare/securi…
Run it on all your software. Run it with the free models. Use it even if you used a model to audit something - it will find much more things. Works in all agent harnesses and is model independent.

Steve @OM3RG1 and I had some fun over the weekend building a HF log-periodic antenna. The results are promising, but it still needs a bit of fine-tuning.

Slovakia just approved Tesla FSD (Supervised) 🇸🇰
Slovakia’s Ministry of Transport has officially recognized the preliminary approval for Tesla’s Full Self-Driving (Supervised) system
That makes Slovakia the 9th EU country to approve it:
- Netherlands
- Czechia
- Belgium
- Denmark
- Lithuania
- Estonia
- Croatia

Tesla FSD’s expansion across Europe keeps accelerating

what if an ESP32 was a Chinese controlled SDR that was literally in every home in America and in many critical pieces of infrastructure
What If an ESP32-C5 Could Become an FPV Receiver?
C5VRX turns a Seeed Studio XIAO ESP32-C5 into a 5.8 GHz analog FPV video receiver.
It captures raw I/Q samples at 40 MS/s, performs WBFM demodulation using the ESP32-C5 BitScrambler, then outputs CVBS through PARLIO and a simple 6-bit resistor DAC.
What makes this really interesting is that the CPU doesn't have to process every pixel. Dedicated hardware handles much of the real-time pipeline.
A tiny ESP32-C5 doing RF, DSP and video output is pretty wild.
Would you try building this?

Testing 15 Euros ESP32 : 80Mhz wide spectrum on 2.4Ghz with recent hack : here is DATV and wifi. Next step : getting I/Q and having TX ! A new horizon for cheap sdr : eSpDR.

Ok, so let me get this straight: The guy takes opensource (GPL) firmware (usrp) and software (sdr++), vibeslops some mods, and now sells those for $20, without providing the source code. Are we really promoting blatant GPL violations now?
