George Makarow / From the workshop

Same hands.
New tools.

After 43 years as a master cabinetmaker, I bring the same patience, accuracy, and problem solving to electronics, programming, 3D printing, and RC projects.

These are the builds, experiments, and lessons from my bench. I’m still learning — every bug has its lesson.

01 / My builds & experiments

On the workbench

From a button-controlled motor to wireless cars. Open a project on GEOMAC for the available photos, videos, code, and build notes. Documentation is added as each project develops.

George’s breadboard with a push button, Uno-compatible controller, ULN2003 driver board, and small geared stepper motor.

My workshop project

Arduino button-controlled stepper motor

One button, one movement: an Arduino Uno drives a 5V 28BYJ-48 through a ULN2003 board. Photo, video, labelled wiring, parts list, and sketch included.

Complete — working

Open project on GEOMAC

George’s joystick, Arduino-compatible controller, mini breadboard, and SG90 micro servo on the bench.

My workshop project

Arduino joystick servo control

A joystick brings an SG90 micro servo to life through an Arduino Uno. Build photo, demonstration video, supplied wiring reference, and parts list included.

George’s ESP32-WROVER breadboard with a lit LED beside an Android phone displaying Bluetooth LED ON and OFF confirmations.

My workshop project

ESP32 Bluetooth LED control

An Android phone switches a breadboard LED on and off over the ESP32’s built-in Bluetooth. Build photo, video, wiring, parts list, and sketch included.

My workshop project

Bluetooth-controlled car

My own Bluetooth-controlled car, built around an Arduino Uno and HC-05 module. 3D-printed chassis, parts list, photos, and a draft Arduino sketch.

Build notes

Open project on GEOMAC

Pico 2 car with four yellow wheels, a black chassis, L298N motor driver, Pico board, battery pack, and wiring.

My workshop project

Pico 2 Bluetooth car

My completed Pico 2 Bluetooth car, with an L298N driver and four geared motors. Photo, parts list, sketch, and 3MF print project included.

Open project on GEOMAC

George’s breadboard with an Arduino Nano, two RGB LEDs, six resistors, jumper wires, and a breadboard power module.

My workshop project

Two RGB LEDs — slow colour fading

Two common-anode RGB LEDs slowly fade through different colours, controlled by an Arduino Nano. Breadboard photo, video, and wiring guide included.

My workshop project

Wi-Fi car

A working Arduino R4 WiFi car with L298N motor driver, parts list, and four STL files. Photo shows the earlier UNO R3 setup; the reference sketch needs checking.

02 / Kit builds

Learning from other makers

Kits I have assembled and tested. The original designs belong to ELEGOO and Freenove; these entries document my builds.

George’s assembled red ELEGOO Conqueror tank on a blue workbench surface, with tracks, camera, ultrasonic sensor, and infrared remote on its chassis.

03 / Software projects

Building with code

G-Portal — personal cloud storage

A personal PHP and MySQL project built one tool at a time: login, uploads, file and folder management, search, selected ZIP downloads, deletion previews, and dashboard storage statistics.

A practical place to learn debugging, reusable layouts, and how a web application fits together.
