What if an ESP32-S3 could hear a drone before you could see it? Agam Rossen's VolAnti is an open-source acoustic drone detector built around an ESP32-S3, four MEMS microphones, e-paper display and LoRa radio. It analyzes the harmonic signature of spinning propellers instead of looking for radio signals, making it interesting for detecting fibre-optic FPV drones that can leave the radio spectrum silent. The concept could be useful for perimeter monitoring, wildlife & environmental monitoring, industrial site awareness, event security, search and rescue operations and early-warning sensor networks, especially where visual detection or conventional radio-based detection is difficult. The creator reports 104 m measured detection, 0.23 s alert latency in its fastest detector, and roughly 18–22 hours of battery life. What I really like is how much signal processing, embedded hardware and wireless communication has been packed into a small device. Would you build an acoustic sensor like this?

Billion dollar idea: Lovable for hardware A new startup partners with a few factories in China that can ship parts in days All you have to do is talk to the app about what you want and it follows the best possible hardware engineering practices and gets you the spec and allows you to order Think of: > desk lamps > phone mounts > custom decor > electronic gadgets and more For an additional price, it will come assembled ;) Boom. Vibe hardware.

全网首只 DIY 复刻的 Microduck 诞生。 恭喜中国的 FanGe。 视频内容包括设备选型、结构打印、组装细节、调试过程和注意事项。 视频较长，可以收藏了再慢慢研究…… 最后，祝大家早日复刻出自己的 Microduck。

What if you 3D-printed your own robot dog? A guy built ElectroPup, an open-source quadruped powered by a Raspberry Pi 5 and 12 BLDC motors. It uses CAN bus motor control, a 9-axis IMU, custom PCBs and a 6S Li-ion battery. The project also includes CAD files, PCB designs, BOM, firmware and MuJoCo simulation. A seriously cool DIY robotics project combining 3D printing, electronics, motor control and software.

Software has become easier to build, yet hardware still feels really hard That's why we're building blueprint.am enter a prompt and get a wiring diagram, BOM, Mech view, and step by step build instructions It's the easiest way to go from idea to prototype

JUST IN: Dyson launches a $499 AI toothbrush with a built-in camera that identifies gaps between teeth & automatically squirts them with mouthrinse.
