Доработать готовую программу

Hello. Is it possible for you to create a small camera that can rotate, be controlled from an iPhone via a wire, and be powered by it through a wire or a power bank? Similar to the one in the photo, but it can be without a casing, the quality should be good. If possible, how much would this approximately cost? My main requirement is that I can use and control it using only my phone or a small joystick like on gamepads. When I need to quickly check what the camera sees, I should be able to connect a cable to the phone, see the image, and turn the camera in the desired direction using the joystick. Everything should happen quickly.

Need an electronics engineer to transfer an existing device from a breadboard to a full PCB project. There is a working prototype assembled on a breadboard. It is necessary to analyze the current connections, correct the schematic if needed, develop a schematic diagram, and create a PCB layout for the subsequent production of a test batch. The device is based on ESP32-S3 and includes: I2S microphone; RTC DS3231; LoRa SX1278; GPS module with UART and PPS; autonomous power supply; service connection for firmware and diagnostics; status indication. What needs to be done: understand the existing prototype on the breadboard; check and refine the schematic diagram; select or clarify components, ratings, power supply, and protection; develop the PCB layout considering the features of ESP32-S3, I2S audio, LoRa, GPS, and RTC; provide connectors, test points, firmware, and diagnostics; perform ERC/DRC checks; prepare a set of files for production and assembly. Expected results: output files in KiCad or Altium Designer; schematic diagram in PDF; PCB layout; Gerber and drill files; BOM; Pick&Place / CPL file; a brief description of the changes made, recommendations, and technical risks. Preference will be given to a performer from Kyiv: it is desirable to have the opportunity to personally show the prototype, discuss details, and conduct a joint technical review if necessary. In the response, please indicate experience with ESP32, autonomous power supply, radio modules, and examples of similar work.

Development of a Flight Controller for Fixed-Wing UAVs An experienced Embedded Hardware Engineer is needed to develop a flight controller for fixed-wing UAVs. Tasks: develop the electrical schematic; design a multilayer PCB; select the component base; prepare Gerber, BOM, and Pick&Place for mass production. Main requirements: microcontroller STM32H743 or equivalent class; functionality similar to Matek H743-Wing V3 (without copying); compatibility with PX4 or ArduPilot; interfaces: CAN, UART, SPI, I2C, USB, PWM; support for connecting GPS, IMU, barometer, telemetry, and other peripherals; maximum use of components that meet NDAA requirements (without using Chinese components where possible). Mandatory when responding: describe your experience in developing Flight Controllers or other Embedded platforms; provide examples of completed projects; indicate which CAD systems you use (Altium, KiCad, etc.); specify estimated timelines and costs for completion. Preference will be given to contractors with experience in developing electronics for UAVs, robotics, or avionics.
