Development and Testing of a Low Cost Ultrasonic Leak Detector
This study focuses on the development of an ultrasonic leak detection system utilizing the Arduino Nano 33 BLE Sense Rev2 board. The research aimed to create a compact and cost-effective solution for identifying leaks in high-pressure pipes. Algorithms were designed to enable lossless recording and processing of sound data captured by the onboard MEMS microphone. Key signal processing techniques, including the implementation of an IIR high-pass filter and RMS calculation, were employed to detec…

Hvor var KI-ekspertene fŸr det smalt? spŸr Kenth-Arne Hansson i Khrono. https://www.khrono.no/hvor-var-ki-ekspertene-for-det-smalt/970818
Mitt svar viser til at dersom flere hŸrte på det kunstnere sier og kunsten viser ville samfunnet være bedre rustet…

Hvor var KI-ekspertene før det smalt?
Skoler og universiteter ble tatt på sengen og famler i møtet med kunstig intelligens. Hvorfor ble vi ikke varslet av et akademia som i tiår har sittet med innsikten?

It Takes 0.44 Seconds to Crack These PINs - Are You Using One?
The security level of 4-digit code remains uncertain. Our research found that it takes 0.44 seconds for AI to crack your PIN.

wooohooo, first very early/experimental release of klutshnik running on a xiao esp32s3 over BLE: https://github.com/stef/klutshnik-zephyr

Ich suche Spezialisten für #Bluetooth Low Energy #BLE
Eine Bekannte von mir hat Kinderdiabetes. Der Blutzucker wird ständig von einem Sensor überwacht, der die Daten per BLE am eine Handy-App funkt. Das Vorgängermodell machte das zuverlässiger, hatte eine größere Batterie, kA. Nachts bricht d…

Delay Optimization in Remote ID-Based UAV Communication via BLE and Wi-Fi Switching
The remote identification (Remote ID) broadcast capability allows unmanned aerial vehicles (UAVs) to exchange messages, which is a pivotal technology for inter-UAV communications. Although this capability enhances the operational visibility, low delay in Remote ID-based communications is critical for ensuring the efficiency and timeliness of multi-UAV operations in dynamic environments. To address this challenge, we first establish delay models for Remote ID communications by considering packet…
