Smart Pill Reminder with YOLOv8 on Raspberry Pi
This technical tutorial demonstrates how to build a real-time pill identification and reminder system using YOLOv8 for multi-pill detection and semantic segmentation, running on a Raspberry Pi. The guide covers system architecture (edge inference with OpenCV), training a YOLOv8 segmentation model, exporting optimized model formats (OpenVINO/NCNN) for Raspberry Pi deployment, and using MQTT (Paho-MQTT) to trigger physical alarms or send status updates to apps or dashboards. The article also outlines production considerations such as model quantization, secure streaming, and OTA updates.
Practical tutorial on edge AI and embedded inference (YOLOv8 on Raspberry Pi) demonstrating patterns (MQTT, model export, quantization) useful for engineers building low-latency IoT/vision systems; limited direct impact on core AdTech/MarTech products.

Key Takeaways & Evidence Grounding
- The tutorial builds a real-time pill identification and reminder system using YOLOv8 for detection and semantic segmentation on a Raspberry Pi.
- Training example uses Ultralytics' YOLOv8 segmentation model (example: model.train(data='pills.yaml', epochs=50, imgsz=640, device='cpu')).
- For Raspberry Pi deployment, the article recommends exporting models to OpenVINO or NCNN to improve inference FPS.
- The system uses OpenCV for frame capture and preprocessing and Paho-MQTT for messaging to trigger physical alarms (e.g., ESP32-powered buzzer) or update dashboards.
- Production considerations listed include model quantization, secure data streaming, and OTA updates for embedded devices.

AI Pharmacist Prototype: OCR + RAG for Drug Interactions
This tutorial demonstrates a prototype 'AI Pharmacist Assistant' that uses Optical Character Recognition (Tesseract) to extract medication text from images, a local SQLite knowledge base to store curated drug-drug interaction records, and a Retrieval-Augmented Generation (RAG) pattern to provide the LLM with grounded medical context. The example integrates the OpenAI SDK (example uses model "gpt-4o") for final LLM reasoning and returns concise safety summaries based on detected interactions. The author highlights production safety concerns (dosage, patient history, multi-ingredient products) and suggests next steps such as NER fine-tuning, mobile integration, and FHIR EHR connectivity.

Edge Autonomy Agent: Gemma 4 on Raspberry Pi 4B
A step-by-step technical guide (published 2026-05-09) showing how to run a local autonomous AI agent on a Raspberry Pi 4B (8GB RAM, SSD boot) by combining OpenClaw with Gemma 4 E2B (Q4_K_M) and a community fork of llama.cpp that implements TurboQuant KV-cache compression. The author details hardware and OS tuning (SSD boot, swap increase, thermal management), building the turboquant-enabled llama.cpp on ARMv8 (NEON), downloading GGUF-quantized Gemma 4 weights, running llama-server as an OpenAI-compatible backend, onboarding OpenClaw to the local model, applying the KheAi Protocol OODA persona, using Tailscale for secure remote access, and optionally routing heavy tasks to Google’s Gemini API for hybrid cloud-edge reasoning.
On-device Object Detection and Tracking with Kotlin
A technical tutorial demonstrating how to build a real-time on-device object detection and tracking pipeline on Android using Kotlin, CameraX, and a YOLO-style detector. The article outlines a recommended architecture (camera capture → frame conversion → YOLO detector → NMS → tracker → UI overlay), implementation details for CameraX ImageAnalysis and analyzers, preprocessing/postprocessing steps, tracking via IoU and recommendations to consider SORT or ByteTrack, performance optimization tips (frame resizing, backpressure, buffer reuse, quantization, hardware acceleration), and production considerations such as permission and lifecycle handling. The post includes links to v-modal SDK repositories and a community Discord invite.
