Electronics & Embedded Software Engineer
"I build my own tools. Before I check whether something ready-made exists."
An observation in retrospect: every self-built tool forces a complete understanding of the problem it is meant to solve.
A COM terminal for debugging the boiler controller? Written from scratch, because available terminals lacked simultaneous multi-format data display and a one-click bootloader trigger.
A voltage divider calculator with ADC mode? Built because there was a need to select R1/R2 and immediately see single-bit resolution — no online calculator showed that.
Hardware, firmware, PC applications, production tools, serial-number management. Described here are both products sold in hundreds and one-off projects — each with its own engineering lesson.
Relational Mathematics did not originate in academia — the 2016 boiler controller turned out to be an empirical proof of ARR a decade before the theory was formalised.
A chronology of key breakthroughs. Both tracks converge in 2022–2026.
Portable battery speaker (#02) and a prime divisor search algorithm on ATmega8 (#09). Starting point — electronics as a hobby, not a profession.

Smart home (#22), Resona (#18), MR theory (#17), MR-AI (#20), FochBot (#19), TrueSynth (#16), HPC Shor simulation (#21).
Hierarchy: MR as foundational theory (#17) → five analytical frameworks → MR-AI (#20) combining them all for AI.
Original mathematical theory describing the structure of prime numbers through rhythmic relations, partitions and rotational models. 6 scientific preprints on Zenodo.

Three projects described in depth — problem genesis, key innovations, outcome.
A feed-type coal boiler with no automation — maintaining temperature requires manually adjusting the blower fan. Available thermostats work in ON/OFF mode, leading to large oscillations and inefficient combustion.
The blower is driven by an induction motor. Standard solution: VFD inverter. Applied: phase-angle firing delay of the triac relative to the zero-voltage crossing. Fan torque scales as M ∝ n² — motor stabilises naturally at lower speed. Implementation cost: zero.
Every 15 seconds the firmware computes the discrete temperature derivative (trend) and decides based on the direction of change, before the threshold is crossed. Three symbolic states: T↑ (reduce airflow), T→ (hold), T↓ (increase). The D-term of a PID controller — implemented without libraries on an 8-bit MCU.
Autonomous vehicle electrical monitor — classifies installation state via FSM: charging / parked / engine running. Bar graph calibrated to lead-acid chemistry. Automatic backlight brightness on engine start. Two DS18B20 channels. 8 backlight colour options.
Commercial timing system for quarter-mile racing on ATtiny2313 (2 KB flash). Requirements: two independent timers (0.01 s lap + 0.001 s reaction), false-start detection, RS232/RS485/USB, MMC, RTC — all within 2 KB.
Timer multiplexing in one ISR — two independent measurements without interrupt conflict. Watchdog reset as flash optimisation — WDT reset saves tens of bytes of code. Technique used commercially in production devices.
