Budget: 6000 UAH Deadline: 15 days
It is possible to make a board that will measure the temperature, and display the indication on a Chinese LED matrix of any size.
A temperature meter with a large indicator needs to be made so that the temperature readings can be seen from a distance of 4m. The temperature should be monitored by people with poor eyesight, so the height of the digits should be 6 ... 20 cm. The type of temperature sensor is Pt100 with a range of -50 ... +250 °C (photo 1). The display format should be wall-mounted.
There are ready-made solutions for civil thermometers with large displays on the market (photo 3), but all of them display temperatures up to 99 °C. There are also industrial meters such as ОВЕН, AQTeck, ТЕРА, Мікрол, etc. (photo 2), but they have digits no larger than 2cm in height.

і ще питання:
на дисплеї має відображатися напис "+250" чи просто "250"
тобто максимальна кількість знаків на дисплеї 4 чи може бути 3наприклад:
250
-50
прилад буде встановлено в приміщенні?
які вимоги до корпусу, щодо захисту від пилу та вологи?
Вибачте, відповів на ваші запитання через кнопку "додати повідомлення".
Доброго дня, терміни 10 днів, температуру достатнь відображати в діапазоні 0 ... 199.
Прилад буде в приміщенні де багато пилу і температура може коливатися від 0 до +50 °С.
Need a contractor for the development of UAV avionics of aircraft type We are looking for a specialist or team to develop the electrical schematic and prepare the equipment specifications for UAVs of aircraft type. Scope of work: development of the principle electrical schematic of the onboard system; selection and specification of all electronic components and equipment; description of connections and interfaces between components; preparation of a set of technical documentation. Requirements for the performer: experience in developing electronic systems for UAVs or robotic complexes; knowledge of modern component base and electronic design tools; experience in preparing technical documentation. Please send information about relevant experience, examples of completed projects (if possible), and estimated timelines and costs for the work.
A compact electro-mechanical control unit needs to be developed: a motor-reducer for connecting to an existing mechanism of gears and rails, controlled by a key with smooth lighting activation. Switch key - the mechanism is such that the key is inserted into the lock - different key turns trigger different actions. 1 - turning on/off the lighting 2 - starting the mechanism for lifting the covers A motor needs to be selected that will ensure smooth movement of the gears: The entire structure is 60x60 cm, and a small motor needs to be attached, along with miniature lighting. Part of the space for this is ready - if it's not enough, we will come up with a solution based on your recommendations.
Need a professional engineer to calculate and design a modular trailer platform with a load capacity of 60 tons for a ready-made chassis. There are factory drawings. Changes need to be made.
It is necessary to manufacture an aviation wing, I will provide the drawing or 3D model. I am considering materials such as: aluminum - extrusion or covered frame, carbon fiber composite materials your option.
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.
