Two Eyes, One Tiny Chip: This Open-Source Board Computes Stereo Depth So Your Arduino Doesn't Have To Hardware hacker machinehum (Rootkit Labs) has built 4reel, a small open-source stereo vision board that gives robots depth perception without a Raspberry Pi or a PC riding along. Two OV9281 global-shutter cameras sit at either end of the PCB, and the depth maths runs on the board's own Rockchip RV1103 chip. Your Arduino or ESP32 just reads the results over UART. Powered by a single-core 1.1… |

VolAnti: An Open-Source ESP32-S3 Device That Detects Fibre-Optic Drones With No RF Control Link, Using Sound A maker named Agam Rossen has created VolAnti, an open-source acoustic drone detector that identifies nearby multirotor drones by listening to the sound of their propellers. Unlike traditional drone detectors that look for radio-frequency signals, VolAnti focuses on the sound produced by spinning blades. This approach is particularly relevant to fibre-optic-controlled FPV drones, which send… |
