Showcase of my personal projects, engineering challenges, and ideas.
A USB-C powered (up to 100 W) mobile soldering station engineered both for working on the go, as well as stationary setups. While it was especially designed to be compatible with JBC irons, it can operate any iron that uses a thermocouple sensor.
Löti delivers precise temperature control, a compact form factor (fits in a Hammond 1455C802 enclosure), and fully open-source hardware and firmware. Browse schematics, PCB layouts, and firmware on github.com/elagil/loeti.

A miniaturized four-channel Class-D amplifier with many digital inputs, designed around the powerful STM32H723, and providing up to 4 x 25 W of power output.
After developing my first DSP amplifier Blus, I found the Analog Devices DSP and its software too limiting (proprietary toolchain with little flexibility), so this version gives more control, has lower cost, and offers better integration options. Ideal for multi-channel audio applications, with open firmware and flexible inputs. Find it on https://github.com/blus-audio.

Typing comfortably and efficiently felt out of reach with off-the-shelf options, so I embarked on designing my own. Over multiple revisions, I tailored layout, key spacing, firmware (using QMK and ZMK), and switch types to match my hands and preferences.
The end result reduces strain and improves my speed and precision in daily use. If you want to build your own, check out https://github.com/elagil/zmk-config.

This is a four-channel Class-D amplifier based on the popular Analog Devices ADAU1452 DSP. While commercial plate amplifiers exist, they can be very expensive and often lack versatile digital inputs or flexible control. Blus combines high-quality Class-D amplification with flexible input options, digital control, and a more accessible design.
All the design files are available on github.com/blus-audio.
