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:
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.

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.

Plane Radar is an open-source ESP32 firmware that transforms an ESP32-C3 with a 1.28-inch round display into a live ADS-B aircraft radar. It visualizes nearby aircraft in a sonar-style interface, showing their position, distance and flight details in real time.
Features of the project:
Plane Radar is a compact and easy-to-build project for aviation enthusiasts and ESP32 makers. The materials are available on

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:
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.

Developed from the scratch, this project explores a compact robotic platform that combines two-legged articulation with wheeled locomotion. The design prioritizes stability, responsive movement, adjustable height, and portability.
Features of the project:
The project combines mechanical design with a compact electronics and control system built around a Teensy 4.1, ODrive motor controllers, magnetic encoders, an IMU, and CAN bus communication. Its 6-DOF structure and multiple PID controllers enable stable balancing, velocity control, and dynamic leg adjustment.
Impulse is particularly interesting for robotics enthusiasts and makers exploring balancing robots, actuator control, and practical control theory. Its detailed hardware and control approach also make it a useful reference for people building their own wheeled robots.

Samsung has raised prices for new orders on its 4nm, 5nm and 8nm foundry processes, with increases of up to 15% for some customers in China and the U.S., according to Reuters. The biggest hikes are reportedly affecting Chinese chip designers, while Samsung’s 4nm facility in Pyeongtaek has been operating at full capacity since late last year as AI-related demand continues to grow.
The price increases could help Samsung’s loss-making foundry business move toward profitability as demand for advanced chips remains strong and competitors such as TSMC also raise prices. Samsung’s foundry business still trails TSMC significantly in market share, but growing orders from companies including Tesla, Apple, Broadcom and Nvidia are strengthening its position.

Robot “Tiangong” made headlines at the 2nd World Humanoid Robot Games in Beijing by completing the 400m race in 38.15 seconds, beating the previous human world record of 43.03 seconds. The robot is part of China’s state-backed X-Humanoid program and is built as a platform for advancing humanoid robotics, with its latest version featuring 43 degrees of freedom and high-dynamic movement control.
A notable part of Tiangong’s development is that some of its technology is open source. X-Humanoid has released components including
