Embedded Systems & Microcontrollers

It is necessary to integrate the NCS with the automatic launch system (catapult with a microcontroller) to transmit a signal to the microcontroller, which will initiate the operation of the catapult 500 meters away from it.

Create compatibility between the ground control station, automatic start system (SAS), radar, and the aircraft.

It is necessary to refine the existing Bitclock rev3 PCB in KiCad. Project sources: https://github.com/goat-hill/bitclock/tree/master/bitclock-pcb/rev3a/kicad Task: 1. Change the size and shape of the board to fit the new STEP/3D model of the case. 2. Move/replace the current power connector with USB-C. 3. Redesign the monitor connection port to an 8-pin connector. 4. Arrange components so that the board fits correctly into the case according to the mounting points. 5. Preserve the existing functionality of the board. 6. Check the alignment of the board with the 3D/STEP model. 7. The output should include ready KiCad files + updated 3D model/fit check. Main requirement: a specialist in KiCad/PCB design is needed, who can work with STEP cases and mounting points.

We are looking for a project - electronics engineer / Embedded Developer. Needed - to develop an electronic circuit; Program several microcontrollers C/C++ / Embedded development of the logic for the operation and connection of the hardware computing unit and sensors testing and debugging of electronic devices and their integration into the testing environment Experience in UAV/UGV, robotics, or defense-tech will be an advantage. Preferably in Kyiv to provide access to hardware.

It is necessary to investigate the electronic block "pulse current generator." Required measurements: pulse frequency, signal shape, pulse duration, duty cycle, output voltage to the coil, current through the coil, power consumption, resistance/inductance of the coil, heating during operation. The device is powered by 220 V. A specialist with an oscilloscope, current probe, differential/isolated probe, and LCR meter is needed. A short written report with photos of the oscillograms is required.

We need a specialist or a team to develop a complete smart home ecosystem. Project idea: to create a central device/hub that can connect various smart home devices: lighting, sockets, climate control, heating, sensors, cameras, locks, appliances, security scenarios, and other devices from different manufacturers. We need not just a beautiful interface, but a full-fledged "smart home" system where all devices are integrated into one understandable ecosystem. What should be in the system: 1. Central hub / main device - a device through which the entire home is managed; - connection and setup of new devices; - compatibility with devices from different manufacturers; - local control, so basic functions work even without the internet; - the possibility of further connecting to the cloud and a mobile application. 2. Device connectivity - adding different types of devices: lamps, sockets, thermostats, sensors, cameras, locks, heating, air conditioners, appliances; - grouping devices by rooms; - displaying the status of each device; - controlling each device individually; - the ability to create connections between devices. 3. Home management - turning lights and sockets on/off; - managing temperature and climate; - managing heating; - managing scenarios; - monitoring energy consumption; - notifications about important events; - manual and automatic control. 4. Scenarios and automation - "if an event occurs, perform an action"; - for example: if motion is detected at night, turn on the light; - if the temperature drops, turn on the heating; - if no one is home, turn off some devices; - if a door/window is open, send a notification; - schedules based on time, days of the week, and home states. 5. Interface - a beautiful modern dashboard for managing the home; - a convenient room screen; - control of individual devices; - displaying temperature, light, energy, security; - an understandable interface for the average user; - preferably support for tablet/wall screen; - a mobile application in the future. 6. Energy and statistics - collecting data on electricity consumption; - statistics on devices and rooms; - graphs for day, week, month; - approximate cost calculation; - recommendations for energy savings. 7. Security - motion sensors, door/window opening sensors, smoke, leaks; - cameras and notifications; - "home", "away", "night" modes; - event log; - access protection for home management. 8. Scalability - the system should be built so that in the future new devices, brands, protocols, and functions can be added; - it is important that the project is not a one-time prototype but can evolve as a product. Who we are looking for: a specialist or team who understands smart home not just as an interface, but as a whole system: device, connection of various gadgets, management, automation, security, energy, mobile/wall control. It is important for us that the contractor can: - propose the right architecture; - explain which central device is better to use or develop; - think through the connection of devices from different manufacturers; - create a convenient management system; - lay the foundation for a future product; - take the project from idea to working solution. In your response, please write: 1. Have you had experience with smart homes or IoT? 2. What devices and protocols have you already connected? 3. How would you propose to build such a system? 4. What is needed for the first working prototype? 5. Approximate stages, timelines, and budget.
