PID Gain Behaviour on a Ball-Balancing Rig
Observing how proportional, integral and derivative terms behave on a physical plant. Tuning runs are being recorded on video; quantitative gain tables will be published once repeated runs are logged.
Building a Six-Class Archaeological Detection Dataset
Curating and annotating a YOLO dataset for coin, inscription, jewel, pottery, skeleton and statue, including a custom image downloader and Roboflow export pipeline.
TFLite Inference Experiments for On-Device Detection
Converting trained YOLO checkpoints to TensorFlow Lite and measuring feasibility of on-device inference for the archaeology robot.
2.4GHz RF Baseline Methodology
A defensive spectrum baseline for comparing current radio activity against an observed norm using dual nRF24L01 receivers.
IMU Sensor Bring-Up on the ESP32 Flight Controller
Reading MPU6050/MPU6500-class gyroscope and accelerometer streams on the ESP32 and preparing the raw data path for attitude estimation.
Load Behaviour of a Fully Printed Bevel + Helical Gearbox
Breadboard experiments to characterise a printed gearbox under load before torque specifications are published.
Tool-Calling Grounding for a Code-Understanding Agent
Design notes on keeping an LLM agent grounded in real codebase state through read/search tool calls before edits.
I2S Audio Chain Design for an Embedded Voice Assistant
Selecting and connecting INMP441 + MAX98357A on the ESP32 I2S bus for a clean speech-in / speech-out path.
