Wtf does this do

This is a hobby electronics project that takes a radar sensor's data feed and displays it, with sound, on a handheld Linux device called a Clockwork Pi uConsole, instead of the small Arduino screen used in the author's original build. It is a second output option for the same underlying radar hardware. The setup works like this: an RD-03D radar module sends readings over a serial connection to a small microcontroller board, the Seeed XIAO ESP32-S3, which groups together any detected targets within one meter of each other into a single point, then broadcasts the combined data over Wi-Fi as its own access point rather than connecting to an existing network. Any device that joins that Wi-Fi network receives the data automatically. A Python script running on the uConsole connects to that network, listens for the broadcast, and renders a fullscreen radar screen: a sector view with range rings, dots for each target, a target list, and a running distance readout. It also generates real sonar-style ping sounds with NumPy, where the pitch and rate of the pings change based on how close the nearest target is, rather than playing the fixed buzzer tones used on the Arduino version. Target positions are smoothed between updates so they move fluidly, and if the wireless connection drops, targets clear from the screen instead of freezing in place. The README lists the exact wiring between the radar module and the microcontroller, plus a bill of materials including a step-up converter, a USB-C battery charging module, and a small LiPo battery. It includes a clear safety warning: LiPo batteries can catch fire if wired incorrectly, and the radio hardware must comply with regulations in your region. The author shares it as-is, with no warranty, for anyone who wants to build their own copy, and asks that documentation errors be reported as issues. The README does not state a software license.
