It is necessary to customize a standard (vending) machine to meet personal needs/brand. There is a mechanical vending machine that needs to be transformed into a device with updated functionality. A system integrator, automation engineer, or electronics engineer is needed to develop custom equipment, who can offer technical solutions and implement them. Main tasks: assess the possibility of modifying the existing machine; change the internal structure if necessary; develop a new product dispensing mechanism (if necessary); integrate the necessary electronics and control; create a unique appearance according to my brand; ensure reliable and stable operation of the device. Provide further maintenance of the machine (if necessary) Expand the network of machines for an additional fee I expect the contractor to propose optimal technical solutions, explain possible limitations, and deliver a quality finished product. I am ready to discuss the concept in detail after selecting a contractor. Payment will generally be higher, it all depends on your skills and abilities. Preferred payment from one individual entrepreneur (myself) to another individual entrepreneur (yours) I would appreciate a consultation.

Design the components and assemblies of the extrusion line: dies, calibrators, cooling baths, cutting devices, as well as peripheral equipment, fixtures, etc. As auxiliary materials, there are photos, videos, documentation in PDF, and 3D models that can be refined according to our technical specifications. I will send the materials after the interview. From you, I need 3D models, drawings, specifications, layouts - all necessary design documentation for the contractor's manufacturing.

Execute the working project (foundation, metal structures, roofing) Submit a visualization for approval with the client

A company, production team, or workshop is needed to implement a large park composition in the form of a cat and mouse as per the attached reference. We are interested not only in the development of a 3D model and drawings but in the full cycle of work: design, manufacturing of the metal frame, exterior decoration, delivery, and installation of the finished figures in the park area.Approximate dimensions of the cat — total length — 8 m; — height of the head — 3.24 m; — height at the withers — 2.34 m; — width of the body — 2.4 m; — length of the head — 1.8 m.Approximate dimensions of the mouse — total height — 1.8 m; — body length — 0.81 m; — height at the withers — 1 m; — total width with ears — 0.9–0.95 m. The figures will be installed outdoors in the park area and will be used as a decorative art object and photo zone.Expected scope of work Development of an original design for the composition based on the reference. Creation and approval of 3D models. Engineering design of load-bearing metal frames. Calculation of the stability of the structures and the method of attachment to the base. Division of the large figure into transportable modules. Manufacturing and anti-corrosion treatment of the metal frame. Formation of the volume of the figures using metal mesh or other suitable technology. Coating with high-quality artificial grass, resistant to sun, precipitation, and frost. Manufacturing of eyes, snouts, ears, and other decorative elements from weather-resistant materials. Delivery of the finished modules to the installation site. Assembly, securing, and installation in the park area. It is necessary to consider wind and snow loads, possible contact with visitors, children's safety, absence of sharp elements, water drainage, and the possibility of further maintenance. Preference will be given to contractors who have their own production or a permanent production team and can take responsibility for the entire turnkey result. In your proposal, please indicate: — which stages you can perform independently; — whether you have your own workshop and installation team; — examples of produced art objects, sculptures, or complex metal structures; — approximate cost of the entire scope of work; — approximate timelines; — terms of delivery and installation; — warranty on the metal frame and exterior coating. Installation location: [Uzhhorod, Zakarpattia region]. The reference is attached. The design must be adapted and made original, without directly copying protected characters.

Title: Development of electrical schematics (EasyEDA) for data acquisition modules (STM32, precision ADC, galvanic isolation) Task Description: We are looking for an experienced circuit engineer to develop the schematic diagrams for two boards (PCB design is not required at this stage). What needs to be designed: Master module: power input of 24V and communication with the external world via hardware-isolated RS-485. Analog input module: digitization of two channels of industrial sensors (0-10V / 4-20mA). Based on a precision ADC (type ADS1248). A mandatory condition is the presence of an internal digital isolation barrier after the ADC. The boards communicate with each other via SPI. Key requirements (Strict!): Environment: only EasyEDA (Pro or Std). Components: 100% of parts must have part numbers (C-parts) from the LCSC Electronics catalog, as the boards will go for automated PCBA. Base MCU: STM32F103 (or your suggestions for modern equivalents). A detailed, well-written technical specification with a ready reference architecture from Texas Instruments will be provided to the candidate. Bonus: For the specialist who diligently and competently completes this stage (circuit design), a second paid stage — routing of these printed circuit boards (PCB Design) — will be guaranteed.
