LLM-разработка в 2026: навыки, кейсы, требования
Привет, Хабр! Я старший инженер-программист в Финаме и автор курса «LLM-разработчик» в Хекслете. Разговор пойдёт о практике LLM-разработки и о бытов…
I Built an Open-Source J1939 CAN Bus Emulator (Because Vector Tools Cost Too Much)
If you've ever tried to test J1939 diagnostics tooling, integrate a telematics app, or just learn how heavy-duty vehicle networks work, you've proba…
The rules I build by
New here? Start with the overview . Before the rules, a debt. These are not mine alone; they are the labor of a whole career, and every one of them…
How Does Call Noise Reduction Work on a Single-Microphone Phone?
On a phone with a single microphone, call noise reduction cannot work the way it does on flagship smartphones. There is no second microphone signal…
Web Developer = Embedded Developer: Real PHP Now Runs on the ESP32 (v1.0.0)
If you can write index.php , you can already program a microcontroller. That's not a metaphor. PHP on ESP32 just hit 1.0.0 — the first official rele…
Every Millimetre Is Spoken For in a 2.4 mm BLE Logging Card
A sealed logging card is a thickness problem before it is an electronics problem. Every subsystem sits downstream of one decision: how the millimetr…
Evidence-Grade Telemetry: Sensor Sync, Time Bases and Idempotent Ingestion
If you are building the ingestion side of a cold chain or asset tracking platform, there is a category of bug that does not show up in staging, does…
The State of Automotive Grade Linux in 2026: Which Release to Build
The Automotive Grade Linux distribution is not one release on one baseline. As of 26 August 2026 its release-notes page documents three listed relea…
systemd vs BusyBox init: Which Init System Fits Your Device?
For most embedded products with a fixed set of services and no user-installable software, BusyBox init is the right default: small, no dependency ch…
Driving an Undocumented 3nm ASIC with an ESP32: Inside the First Sub-10 J/TH Open-Source Bitcoin Miner
Next week we ship the Bitaxe Naja Duo , and the spec that matters is 9.5 joules per terahash at stock. First open-source home miner under 10. But th…
Buildroot for Embedded Linux — Part 1: Your First Buildroot Root Filesystem
Buildroot builds a cross-compiler, a Linux kernel and a complete root filesystem from source, driven by one Kconfig-style configuration file. Starti…
In-Tree vs Out-of-Tree Driver: Where Your Code Should Live
For hardware your company owns and intends to ship for years, default to putting the driver in mainline and carrying only the part you have not land…
Device Tree Ownership Is Moving Up Into Firmware
On most embedded Linux products the kernel carries the description of the board. Under Arm's SystemReady Devicetree band it does not: the platform f…
How to Use the SH-C30L USB-to-CAN Adapter with Arduino UNO and MCP2515
Controller Area Network (CAN) is one of those technologies that quietly powers a huge number of embedded systems. It is commonly found in cars, EVs,…
Reverse-Engineering SWIO: Why Existing CH32V003 Programmers Fail and How I Built One That Works
I wanted to see if an ESP32-S3 could be used as a programmer for the WCH CH32V003 instead of using a dedicated WCH-Link. The final setup is: PC → ES…
Remote Diagnostics for Low-Power IoT Devices: Stop Treating Them Like Servers
The hardest failures in low-power IoT are often not total silence. They show up as partial signals: battery voltage drifting down, RSSI getting wors…
From Retrospective Liability to Proactive Capability — A Path to Crypto-Agility and Compliance with Embedded Security Requirements
NON-PAPER This paper is distributed solely for discussion purposes. It reflects an independent analytical perspective and is not presented on behalf…
Architecting Mainline-Friendly Products
Mainline-friendly products are designed so their board support lives in upstream Linux, U-Boot, and standard build systems instead of a vendor fork.…
Devres: How Managed Device Resources Work in the Linux Kernel
Devres is the kernel's mechanism for managed device resources: every devm_* allocation is recorded on a per-device list, and the driver core release…
Thermoelectric Energy Harvesting for Batteryless IoT Sensors
Industrial motors continuously reject energy as heat. Under the right conditions, a small part of that heat can power the sensor used to monitor the…
What Actually Happens Between "Export Gerbers" and a Physical PCB Showing Up at Your Door
If you've ever designed a board in KiCad, EasyEDA, or Altium, clicked "Export Gerbers," uploaded a zip file to a fab house, and then a couple weeks…
7 Tuya Matter Pitfalls That Will Kill Your Certification (And How We Avoided Them)
# 7 Tuya Matter Pitfalls That Will Kill Your Certification (And How We Avoided Them) We have shipped several Tuya Matter products over the past eigh…
The Chip That Has No ADC but Still Knows When Its Battery Is Low
Somewhere out in the field, a tiny battery-powered sensor is quietly dying. No warning light, no alert, nothing. One day it just stops responding, a…
Tesla Built the First Wireless Remote Control
In 1898, years before radio broadcasting existed and decades before anyone used the word "electronics," Nikola Tesla stood in front of a crowd at Ma…
Most Embedded CI Stops One Step Too Early
Software teams have spent years making CI feel normal. A pull request builds automatically. Unit tests run automatically. Static analysis, linting,…
Choosing an LCD Panel for Embedded Systems: IPS vs TN Technology Explained
When designing an embedded device, selecting the right LCD panel is often more complicated than simply choosing a display size or resolution. The pa…
