My technical blog
A short place for practical notes, fixes, and technical learnings.
Read latest postsUnderstand why CPU clock speed alone cannot predict MCU performance. Learn how IPC, pipelines, memory wait states, caches, buses, compilers, and workload shape real embedded throughput.
A practical guide to the CoreMark benchmark: what it measures, how CoreMark/MHz is calculated, how it compares with DMIPS, and how to use benchmark results without mistaking them for application performance.
A clear, practical guide to CUDA and NPU hardware for AI and ML workloads, including what they are, how they are used, where they shine, and simple examples for GPU and edge inference.
A practical guide to the most common network protocols: TCP, UDP, IP, DNS, HTTP, HTTPS, FTP, SSH, SCP, NTP, SMTP, POP3, IMAP, SNMP, DHCP, MQTT, and the port numbers and real-world use cases behind them.
Clear explanation of hardware FPU, VPU, NEON, and SIMD instructions and their massive impact on CPU performance. Real benchmarks, use cases, and comparisons showing 10-100x speedups in signal processing, graphics, ML, and math-heavy applications.
A practical guide to Edge AI: what it is, why it matters, which NPUs support it, how to deploy it, where it's used, and best practices for on-device machine learning.
A beginner-friendly, comprehensive guide to understanding CPU, GPU, and NPU: what they do, how they differ, their architecture, real-world use cases, pros and cons, and when to use each for your project. Perfect for engineers and developers.
Complete guide to PWM (Pulse Width Modulation): how it works, frequency vs duty cycle, practical MCU configuration examples, real-world use cases including LED dimming, motor control, and DAC simulation. Clear explanations with working code.
Complete guide to GSM/LTE modems for embedded systems: popular modules (SIM800, SIM7600, EC25), AT command protocol explained, practical examples for SMS, calls, HTTP/MQTT, GPS tracking, and remote monitoring applications with working code.
Complete practical guide to running Pi-hole on Raspberry Pi using Docker: Docker Engine installation, compose configuration, router DHCP setup, and network-wide ad blocking for all devices including IoT endpoints.
A small personal project for exploring mood tracking, visual patterns, and simple user-focused interaction.
A versatile networking and communication toolkit featuring TCP, UDP, MQTT, CAN Bus, Serial Port, and Multicast protocols. Ideal for reliable data transmission, efficient messaging, and robust vehicle communication.
