🧠 Qapla': Training AI on ESP32 microcontroller Qapla' is an open-source project that demonstrates training a transformer model entirely from scratch on an inexpensive ESP32-S3 microcontroller. Instead of running a pre-trained model, it performs the complete training process—including backpropagation and weight updates—directly on the device. Features of the project: ➡️Full on-device transformer training ➡️Handwritten C backpropagation ➡️No pre-trained model required ➡️Open and reproducible setup Qapla' proves that even low-cost microcontrollers can train small transformer models without GPUs or cloud infrastructure. It is an interesting project for embedded AI developers, TinyML enthusiasts, and researchers exploring on-device learning under extreme hardware constraints. ⛓ More information... #projects #esp32 #artificial_intelligence

Features of the project: ➡️Live ADS-B aircraft tracking ➡️Sonar-style radar display ➡️Flight context and weather ➡️Wireless OTA firmware updates Plane Radar is a compact and easy-to-build project for aviation enthusiasts and ESP32 makers. The materials are available on ☁️ GitHub. Its combination of real-time aircraft tracking, customizable firmware and convenient wireless updates makes it an appealing choice for anyone interested in embedded hardware or flight monitoring. ⛓ More information... #projects #esp32

💻️ Nvidia quietly increases Jetson prices by up to 101% NVIDIA has raised prices across its Jetson modules and developer kits by up to 101%, following earlier product discontinuations linked to rising LPDDR4 memory costs. The largest increases affect the Jetson Nano module (from $99 to $199) and the Jetson AGX Orin 32GB module (from $899 to $1,799). The popular Jetson Orin Nano Super Developer Kit has also increased from $249 to $399. The new prices are reflected on NVIDIA's store and most retailers, though some backordered listings may still show the old pricing. NVIDIA has not provided an official explanation for the increases, but industry observers believe they are driven by rising DRAM memory costs and ongoing supply constraints. The company updated the pricing on its official website without an announcement, leaving it unclear whether the higher prices are a temporary response to market conditions or a permanent change to the Jetson product lineup. ⛓ More information... #news #nvidia

🔐 ESP32 Ad-Blocking Dongle This project turns a low-cost ESP32-C3 microcontroller into a compact backup DNS ad-blocking device. By using smart data compression techniques, it can block hundreds of thousands of domains while operating with very limited memory and power. Features of the project: ➡️Blocks 537,000 domains ➡️Uses 40-bit hashing ➡️Requires only 50KB RAM ➡️Offers 10ms DNS responses The novelty of this project lies in squeezing large-scale DNS filtering into extremely limited hardware. By replacing traditional domain storage with an efficient hashing system, it shows that even a tiny $5 microcontroller can handle tasks usually reserved for more powerful devices. ⛓ More information... #projects #esp32
