🎙 AERIS-10: Open-Source Phased Array Radar

Traditional phased array radar systems cost hundreds of thousands of dollars, placing them out of reach for most researchers, drone developers, and hobbyists. AERIS-10 solves this by providing a fully open-source, modular 10.5 GHz radar for under a fraction of that cost, making advanced beamforming and pulse compression experimentation accessible.

Features of the project:
➡️Full electronic beam steering (±45°)
➡️360° mechanical rotation
➡️Two versions: 3km range or 20km
➡️On-board FPGA for signal processing
➡️GPS/IMU integration
➡️Python GUI with maps

This hackable platform removes cost barriers to radar experimentation. It will interest university researchers, drone startups, and serious SDR enthusiasts who have PCB assembly and FPGA experience.

📺 Air Powered Segment Display

This video documents the creation of a unique air-powered seven-segment display that functions as a clock. It shows how vacuum transistors, latching segments, and multiplexing allow multiple digits to be controlled with limited inputs. Inspired by earlier air-powered robots and microfluidic circuits, the video shows the progression from simple air distribution to full computation, including the accidental creation of pneumatic memory. The final build combines solenoid valves, a microcontroller, and a vacuum pump into a working clock with modes like a stopwatch and simple animations.

📺 The current state of LLMs in software engineering

Great video which summarizes of what's going on in software engineering when it comes to AI. As a someone who works as a software engineer himself and has been actively using LLMs for the past few years, I can say that they are nowhere close to replacing software engineers.

💻️ 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.
