Open source : la solution au manque de respirateurs utilisés contre le coronavirus ? Des pistes à base de plateformes comme Arduino émergent à côté de prototypes de systèmes mécaniques à bas coût

Les respirateurs artificiels, utilisés notamment pour les patients en insuffisance respiratoire aigüe, sont essentiels dans les cas graves de coronavirus. En Italie, leur pénurie est devenue le problème numéro face à l’afflux de patients atteints, les hôpitaux sont débordés et parfois obligés de procéder au…

Creating a Simple POV Display Using Flexible PCBs @BugejaCarl

Carl Bugeja has been working on a cool project to create a simple persistence of vision (POV) display using LEDs mounted on a flexible PCB coil. Here is the current video update on the project. You… Source : Creating a Simple POV Display Using Flexible PCBs…

Sub-1GHz mini-PCIe card also handles 2.4GHz links

Gateworks has launched a second-gen “GW16122 IoT Radio” mini-PCIe card for Sub-1GHz and 2.4GHz BT5 LE, Thread, and Zigbee communications. The TI CC1352P driven card has a 20dBm amplifier for a longer range plus up to 352KB flash and open source software. Source : Sub-1GHz mini-PCIe…

“The Arduino lie detector determined that was a lie”

Want to know if someone is telling you the truth? Well, unfortunately Juan Gg’s “USB Polygraph” isn’t a professional product and won’t actually give you an answer. However, it is a neat exploration into biometrics that incorporates Arduino, some sensors, and data visualization. The DIY…

ESP32-Cam Does Time Lapse

Just a few years ago, had someone asked you how much a digital camera with WiFi would cost, you probably wouldn’t have said $6. But that’s about how much [Bitluni] paid for an ESP32-CAM… Source : ESP32-Cam Does Time Lapse
