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
- Slovenia
- Slovakia - (New)
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?

What If Your ESP32 Could Become an SDR?
ESP-SDR turns supported ESP32 boards into a small software-defined radio receiver.
It gives you access to raw IQ samples from the Wi-Fi radio, letting you see the 2.4 GHz spectrum and waterfall in a browser.
You can explore things like RF signals, spectrum analysis, IQ data and wireless interference without expensive SDR hardware.
The ESP32-C5 is even interesting here because it can work in the 5 GHz band.
A tiny development board suddenly becomes a great tool for learning RF and signal processing.
Would you try SDR on an ESP32?

Stejné místo, stejný cíl, nové zážitky! Letos poslední plánovaná akce s Radioklubem AČR a projektem ARDOS. Hasiči se po armádě stali nedílnou součástí našich cvičení. Které složky IZS budou další? #ardos

Nekdo kdo by mel zajem o DIYBMS system s optickym prenosem signalu mezi moduly? Je to starsi revize, ale verim ze to praci jeste udela.. Cell-modules mam desitky kusu, respektive 56ks+ (podle puvodnich 4ks 14S2P sestavy pro kterou to bylo urceno). #retweetPotesi
