I’m looking for a complete design-and-build solution for a smart dispenser that can handle dry food, wet food, and a variety of home-cleaning products in a commercial environment. The core requirement is an automatic sensor-based mechanism that lets customers select and fill exactly the quantity they need, reducing waste while streamlining self-service. Functionally, the unit should: • Recognise a container placed beneath the spout, trigger dispensing automatically, and stop precisely at the chosen weight or volume. • Keep wet and dry chambers fully sealed to avoid cross-contamination, odour transfer, or moisture ingress. • Be robust enough for daily public use—think stainless steel or food-grade polymers that are easy to wipe down and resistant to aggressive cleaning agents. • Offer a straightforward refill system for staff, with clear level indicators on each reservoir. I’ll need detailed CAD drawings, component specifications (sensors, valves, augers/pumps, control board), and an assembly guide so manufacturing can move ahead without guesswork. Firmware for the sensor logic should be included, ideally in an easily updatable format such as Arduino or Raspberry Pi. Acceptance criteria: the prototype must dispense within ±2 g or ±2 ml of the user’s setting, complete a cycle in under five seconds, and pass a 500-cycle durability test without leaks or jams. If this sounds like your specialty, let’s talk timeline and hand-off milestones for design, prototype, and final documentation. Go to [login to view URL] to see what exactly I need.

Hi I am an embedded systems engineer with over 16 years of experience. I have extensive experience developing sensor-controlled electromechanical products, including precision dispensing, load-cell measurement, pumps, valves, augers, motor control, sealed food-safe assemblies, and production-ready firmware. I reviewed the SKUBU model and understand that this must be a reliable commercial self-service system for customers using their own containers—not simply a benchtop dispenser. I can handle the complete product path from concept and mechanism selection through CAD, electronics, Arduino/Raspberry Pi firmware, prototype integration, testing, and manufacturing documentation. The work can be divided into clear milestones: architecture and chamber design, detailed mechanical/electronic design, prototype build, calibration against the ±2 g/ml and five-second targets, 500-cycle validation, then final CAD, BOM, assembly guide, and editable source handover. I will also design for cleaning, refill access, level indication, moisture control, and resistance to jams or leaks. Do you have target reservoir capacities and a list of representative wet, dry, and cleaning products? Should the dispenser integrate with the existing SKUBU card/POS system in this phase? Please contact me to discuss details.

I understand you need a robust, sensor-driven dispenser for diverse commercial applications, much like the automated inventory systems I've developed to precisely measure and dispense liquids and solids. My expertise lies in creating integrated hardware and software solutions that ensure accuracy and prevent waste. My approach will involve a custom-designed dispensing mechanism, likely utilizing load cells for precise weight measurement and potentially flow meters for volume-based dispensing of liquids. For the sensor system, I'll integrate infrared or ultrasonic sensors to detect container presence, triggering the dispensing sequence. A microcontroller will manage sensor input, actuator control (e.g., auger for dry goods, peristaltic pump for liquids), and user interface feedback. Sealing will be addressed with robust gasket designs and potentially air-tight valve systems for each chamber to maintain product integrity. To ensure a perfect fit, could you clarify the typical range of weights/volumes customers will select, and what materials are you considering for the container recognition sensors to ensure reliability across different surfaces? I'm confident we can build a highly efficient and reliable solution. Let's schedule a brief call to discuss your specific needs in detail.

Dear Client, This project requires more than a dispensing mechanism; mechanical design, sensors, control systems, electronics, and automation must work together for a reliable commercial smart dispenser. I can take ownership from concept and system design to mechanical development, sensor integration, control setup, prototype validation, and manufacturing documentation. With 11+ years of experience and 500+ completed projects, I have worked on embedded systems, automation, motor control, and prototype-to-production solutions. The solution will include accurate quantity dispensing, weight/volume control, sealed wet and dry chambers, and reliable performance for daily commercial use. Key risks include dispensing accuracy, sensor errors, mechanical jams, component selection, and long-term reliability. I will mitigate these through requirement review, sensor calibration, prototype trials, and performance testing. Approach 1. Define system architecture, components, and design requirements. 2. Develop the dispensing mechanism, sensors, control system, and prototype. 3. Test performance, optimize reliability, and provide complete documentation. The final design will be modular, manufacturable, easy to maintain, and ready for production. Please share product dimensions, dispensing materials, power requirements, control platform, and production quantity. I can then define the scope, turnaround, and next step. Best regards, Avi Gupta Quality is never an accident.
