Anton Mukhin

Fast learner.
No bad habits.
Passion, patience, and attentiveness are my best sides.

Universal man in IT. A little bit of everything with deep knowledge in some cases.

Started as a tech guy in a computer hardware shop then became a system administrator/engineer at several places, a NOC ingineer at a small ISP and a technical support engineer. During all this time electronics was one of my hobbies. I was able to make it my work since january 2023.

Successfully walked the path from 1st line of support, being 'the boy on the phone' to the last line where I was solving complicated problems and completing different tasks like making custom IT solutions for clients.

As electronics engineer I have successfully integrated into the development and support chain, created several internal diagnostic tools and made the development process more modern by implementing tools and services.

Experience

Electronics Engineer

ECROSKHIM Co., Ltd

Ecroskhim among many things, manufactures X-ray diffractometers, spectrometers, and scanning microscopes that have complex mechanics and electronics inside. My job is to develop and support the electronics for these machines. Communication with a PC, step-motor controls, interfacing encoders, different kinds of sensors, and inter-module communications are some of the tasks I solve in the process.
I do a full cycle of electronics development - from idea through schematics, and PCB design to manufacturing files for a PCB manufacturer. From manual prototype assembling, firmware programming, and debugging to a finished module.

Interests

Apart from being an engineer at work I have several technical hobbies that help me to develop new skills and do some freelance jobs from time to time.

In 1996, I found an old magazine from the 1970s filled with DIY projects. The electronics section immediately drew my attention, particularly a radio transmitter. I started looking for more information, discovered an ancient soldering iron in my grandfather's tools (the largest soldering iron I've ever used), and gathered some old PCBs that became the source of my first components. I made a couple of simple devices from those old magazines. My parents took me to a workshop where I learned the basics with other kids.
Long story short: analog electronics, basic digital electronics, Zilog Z80 processor, Altera MAX series, ATmega8, Arduino, STM32.
And here I am, working as an electronics engineer.

Once, at the beginning of 2016, I came across information about 3D printers, and my world has never been the same! I was absorbed by the technology and couldn’t think about anything else. I started learning 3D modeling, slicing techniques, and different types of plastic. Then I bought my first cheap kit, the "Anet A6," which was a box of many parts that I had to assemble. It was an amazing adventure. I printed a lot of useful items as well as toys.
Now, I have four self-assembled printers. The first one is heavily modified, one is for small items, another for larger ones, and the last is something in between. These printers serve as great helpers for both household projects and freelance work.

Back in 2016, I built my first FPV quadcopter. I still can’t compare the feeling of being inside a flying machine for the first time to anything else! I have been upgrading my drone step by step, enjoying new capabilities. Then I found a local community of drone racers and built a racing drone to compete in competitions.
Now, I have a freestyle drone that can carry a GoPro, a couple of racing drones that can go from 0 to 200 km/h in just one second, and a few smaller ones for flying at home.

I play an acoustic 12-string guitar and an electric guitar when I have free time. Nothing serious, but I've been doing it for a long time, so time has helped improve my skills. :)

Portfolio

For obvious reasons I cannot share full design plans but here are some photos and a cople of simple modules git repos:

Relay module

A simple module to control the power of different parts of the machine, Emergency STOP button, LED lights and a couple of small DC motors via RS-485

PCB - Firmware - Docs

BSV module

A module to control the high voltage power supply and measure its parameters via RS-485

Here are my very simple hobby projects (not all of them, I have much more in the WIP stage that I don't want to share yet). All of the shared ones are available here but I will display each of them below (more photos inside the git repositories):

Filament dryer

Filament for 3D printers should be dried from time to time. I made a dryer out of a broken fruit dryer. Added temperature, humidity, and time control and made presets for different types of plastic. Works good.

Git repository

DiLight

A simple light based on STM32G030 that utilizes ST's VL53L0X laser "Time-of-Flight" ranging and gesture detection sensor.

Git repository

Voron0 extended display

Extended display version for my Voron0 3D printer. It has more connections for external buttons, thermoresistors, addressed LEDs, and GPIOs. Compatible with Klipper firmware and works out of the box.

Git repository

PCB Heater

I feel like I’m reinventing the wheel here! I’m working on a heating platform to solder SMD components. The more time I invest in this project, the more I think about building an oven instead. Nevertheless, it’s a valuable experience!

Git repository

SigGen

Signal generator project. Made in hardware and proven to be operational but I didn't have enough time to write the firmware with all the features planned.

Git repository

McBitFont

A little helper application to create bit fonts and images and export them as C arrays to use in other projects. I know there are applications like that on the internet but I still made it to fit my needs as well as to have some experience in C#
