2026 Patch Notes

Project! Experimenting with pose detection and CNNs Trying to use computer vision to solve Judo!
Built a real-time judo throw recognition system using a CNN-based pose detection pipeline running at 60 FPS. Extracted kinematic keypoint sequences from video frames and trained a classifier to distinguish between throw types based on joint trajectory patterns. Achieved 63% classification accuracy across multiple throw categories, the main bottleneck was feature representation, since similar throws share a lot of overlapping keypoint motion early in the sequence.
Shown here is a Koga Ippon Seoi-Nage

Project!
Designed and built a coherent 4-node ESP32 array for synchronized WiFi channel sounding. The core challenge was getting all four nodes to capture CSI simultaneously, solved through firmware-level timing coordination over a shared trigger. Applied AoA estimation and the MUSIC algorithm in Python to process the spatial signal measurements and generate 2D visualizations of RF signal distribution in physical space.


2.19.26 Version Update!!

Lots of projects and work to come 🙂
Updated training split
Updated Classes/Schedule
