The home heating and ventilation control system provides a complete solution for optimizing the energy consumption of the system. The system consists of a central module that operates on ESP32 microcontrollers and communicates with devices such as a room thermostat (ESP32), air recuperator (from third-party manufacturers), and thermal heads (BusyBee), as well as ventilation valves (BusyBee). Communication of the central module between the room thermostat and the recuperator was carried out using the ModBus protocol, between the thermal heads and ventilation valves a custom protocol based on RS485 was used. The thermostat also operates on the ESP32 platform and features a built-in e-paper display, allowing users to adjust the room temperature and air quality. The thermal heads control the room temperature, while the ventilation valves regulate the volume of air entering each room.

Ampersand builds affordable electric vehicles and charging systems for the five million motorcycle taxi drivers in East Africa. The goal of the project is to create a mechanism that will allow updates to the firmware of electric vehicles and charging systems. The update should be performed during battery charging on the service. During the project were implemented following main features: - OTA - Bootloader - GSM and GNSS submodules - Firmware update process validation - Bluetooth module - CAN configuration - Messages queue - Built file system - Sending VCTU telemetry w/ D-Protocol

the hand sanitizer project for 3Oe Scientific is an aqueous ozone-generating device. The device has an option to be installed with a communication processor (our team develops software for the communication processor) that is capable of connecting to the Internet via cell modem or WiFi. When this option is selected the installation, monitoring, and maintenance are managed via a cloud dashboard. Firmware updates, Event Alarms, and operational status are all communicated to the cloud application on regular intervals, when available.

Development of a system for smart control lighting in rooms, including firmware for custom boards. Developed Linux applications listen to commands from the back-end system (using MQTT) and apply them to change the device configuration and brightness/color of controlled light (using SPI). Also, it communicates with 2 other devices via CAN bus protocol. The firmware has 2 versions and is supplied as Linux image with OTA update function.

UI and background (service) Tizen wearables apps which monitoring user activities (steps, heart rate, calories, data from the accelerometer and gravity sensor, can detect user location, and user falls, localization, translation text phrase to voice and vice versa) and send this data on the backend for processing AI, and if AI detect some anomalies in sent set of data, background app will send an emergency request to caregiver staff.

Data transfer protocol between microcontrollers; developed using the framework Mongoose OS

Project management tool. All-in-one desktop app for project management professionals. Users can create projects, assign tasks, add meeting agendas, generate reports, and make comments. It enables them to undertake different projects, appoint people to specific tasks, share their responsibilities, and monitor work progress. Also, the user has the ability to synchronize files, mail, and databases with colleagues on different devices. On top of that, Oneboard has a multilingual interface and print to disc option.
