This board is no longer available for sale - 12 WiFi radios and 24 antennas - reduced down to 4 external antennas. build/principle of antenna ->LNA->RF Combiner->6 antenna wires for 3 radios doing it 4 times for the reduced attention of having a lot of antennas on the vehicle.

Still playing ESP32 #SDR limited to 2.2~2.7G? New wifi soc support 2.2~3G, 4.4~6G, and support USB3 output 240MB/s !

Found a 5/6 receive-LO mode on the ESP32-S3. eSpDR now reaches ~1.84–2.79 GHz. github.com/h0m3us3r/eSpDR

なるほど、ドライバ1本で交換できるUSB TypeCコネクタかぁ。壊したときの交換が容易だから計測器とか長く使われる製品には良いかもね。 products.jae.com/jp/ja/conne…

Un étudiant de York vient de contourner l'angle mort de toute l'industrie anti-drone 🚁🚫📡 Agam Rossen a construit VolAnti : un boîtier à 50€ qui détecte un drone FPV en écoutant ses hélices, pas sa radio. 4 microphones, une board ESP32-S3, un écran e-paper screen et un module radio LoRa. 📡 Le problème Les drones à fibre optique n'émettent rien. Retour vidéo et commandes passent par un fil de verre. Pour un détecteur radio classique, le ciel est vide. 🔊 La faille Quatre moteurs qui hachent l'air produisent un « peigne » de fréquences à espacement fixe. Le vent et le trafic étalent le bruit. Un rotor, non. C'est de la physique, ça ne se désactive pas. 📊 Les chiffres 104 m de détection en rue, trafic et conversations autour 0,23 s entre le premier son et l'alarme 0 fausse alerte en terrain 18 à 22 h sur batterie 50 à 80€ de pièces, ou 40€ sur breadboard sans soudure 🕸️ Souverain par design LoRa sans serveur ni mesh : chaque unité décide seule et prévient les autres. Écran e-paper qui garde l'alerte même après coupure. 🚫 Périmètre verrouillé Détection et alerte uniquement. Aucun brouillage Hardware CERN-OHL, firmware Apache-2.0. Tout est sur GitHub. Le radar à 200 000 € ne voit pas le drone à 400 €. Le micro à 3 € l'entend.

A few months ago, I bought a ~$10 eBadge on Temu just to see what was inside. That curiosity turned into reverse engineering its BLE OTA flow, firmware format, flash recovery, and eventually running our own firmware over BLE. Released at @DragonJAR CON 2026: github.com/ElectronicCats/ji… Welcome pullrequest, happy hacking!

PwnEye PwnEye can compromise cameras through ONVIF and RTSP. It can play the stream, deface a camera, move it and get a shell. Cameras, printers and other IoT devices are vulnerable to numerous CVEs with publicly available exploits. Hackers can take advantage of these devices and use them as a foothold into the network. hackers-arise.com/camera-hac…

Can’t make this up…the MacBook is using its webcam to look at its screen in a mirror to improve AMD Radeon chip support in Omarchy.

PCB blade, pin and female connector for AC power.
DO you know a part number for this type of TH PCB AC plug / spade / ? @blind_via
