Hi I am an embedded systems engineer with over 16 years of experience. I have extensive experience developing IoT products that combine sensing, precision control, wireless connectivity, data logging, cloud/backend software, and third-party system integration. For this prototype, I would first confirm the required pour accuracy, bottle/spout mechanics, connectivity method, and target POS platforms. I can then develop a practical proof of concept covering liquid measurement, automatic shutoff at a configured volume, unique spout identification, timestamped pour records, and an integration layer for transaction logging and stock reconciliation. I can also support the full consumer-grade product journey from concept and electronics/firmware through enclosure considerations, testing, and production preparation. Relevant commercial projects cannot be shared publicly due to confidentiality, but suitable examples can be shown privately. Do you already have a preferred POS API, and should the prototype operate independently if the network connection is unavailable? Please contact me to discuss details.

Hi, I reviewed the Smart Nip Pourer specification, which requires a gravity-fed smart spout with selectable 30/45/60ml pours, automatic shutoff, BLE data logging, and POS synchronization through Doshii middleware. I am a Senior Embedded Systems Engineer with 10+ years of experience in IoT, BLE devices, embedded firmware, and hardware development, having delivered 20+ connected prototypes including battery-powered sensor nodes, wireless controllers, and production-ready embedded systems with low-power optimization. Approach: ✅ I will design the prototype with a low-power MCU, flow measurement, gravity-fed valve control, battery system, and BLE communication. ✅ I will develop firmware for volume selection, auto-stop pouring, data logging, and wireless transmission. ✅ I will integrate the system with POS/cloud software for pour records and inventory reports. ✅ I will test the prototype with real spirits, checking accuracy, battery life, and reliability. Questions: ✅ Do you already have a preferred flow measurement approach or should I evaluate options such as flow sensors, weight measurement, or valve timing for gravity-fed operation? ✅ Is the first prototype expected to integrate directly with H&L POS, or should we initially validate BLE-to-cloud communication before POS API development? ✅ What are the preferred battery constraints and target production volume for optimizing component selection and cost? Best, Yaroslav

Dear Client, Most bids here will say, "I can build your smart pourer." But developing a wireless smart speed pourer for commercial bars involves several hidden challenges: accurate gravity-based liquid measurement, auto-stop valve control, BLE connectivity, low-power battery management, POS integration, food-safe mechanical design, and reliable operation across different spirit viscosities. PCB Must Innovations can help you develop your Smart Nip Pourer using a risk-first approach, not just a prototype development approach. With 30 years of experience in IoT devices, embedded systems, BLE products, precision electronics, and PCB design, our focus is to deliver a reliable, manufacturable, and production-ready prototype ready for EVT validation. ✅ Where we will add value: 1. Precision liquid measurement with gravity-fed auto-stop control. 2. Low-power BLE hardware with reliable data logging. 3. POS-ready architecture for Doshii and H&L integration. ✅ Suggestion: Finalize the valve mechanism, battery type, and bottle-neck dimensions before hardware development. This minimizes redesigns and improves prototype reliability. Profile: https://www.freelancer.in/u/electronicsdone ✅ Questions: 1. Have you selected the flow sensor and valve mechanism yet? 2. Should the prototype be optimized for one bottle size or multiple bottle types? OOPS, Character Limit! Please message me in the chat I can cover more aspects of your project.

@melopgabriel

Hi, your prototype needs more than a sensor on a spout , it needs reliable auto-stop control, accurate pour logging, and clean POS reconciliation for bar use. I’ve built IoT systems that combine measurement hardware, device firmware, and backend integrations, so I understand the challenges around repeatable liquid tracking, low-latency stop logic, and trustworthy transaction records. For this project, I’d start by defining the pour detection method, then build the control flow for auto-stop, event logging, and spout-level identification. From there, I’d connect the device data to the POS layer so every pour can be tied to sales and stock usage. I can help you move from spec to working prototype with a practical, testable setup. Best regards, Gabriel

@Webslinger01

Smart pourer for bars — I've built similar IoT prototypes with flow control and BLE data logging, so this is right in my wheelhouse. The auto-stop accuracy and POS sync are what separate a demo from something useful behind a bar. → Delivered a BLE-connected dispensing prototype with sub-10% pour accuracy across different liquid viscosities → Integrated IoT devices with middleware for real-time transaction logging and stock reconciliation → Handle the full stack — firmware, electronics, and software integration — so nothing falls through the cracks → $3000 for a bench prototype that demonstrates the core flow, with BLE data transmission and accuracy testing Happy to chat through the details if it sounds like a fit.

@shenglin0617

Hi, This is an interesting product because success depends on much more than PCB design. The challenge is achieving reliable volume accuracy with gravity flow while keeping the pour fast enough for busy bartenders, then turning every pour into useful inventory data. I have extensive experience developing embedded IoT hardware, BLE devices, sensor interfaces, battery-powered products, and production-ready PCBs using Altium Designer, which helps ensure a clean path from prototype to manufacturing. I can evaluate the most suitable flow sensing and valve approach, develop the electronics and firmware, and build a prototype ready for BLE/POS integration. As an engineer based in China, I also have direct access to rapid prototyping, PCB fabrication, 3D printing, and manufacturing resources, allowing faster iterations and lower prototype cost. I'd be happy to discuss the architecture and development plan with you. Best regards, ShengLin Gu.

Building a reliable smart speed pourer is less about the hardware alone—it's about ensuring the embedded device, flow measurement, and POS integration work together accurately in a busy bar environment. That's the approach I'd take for your prototype. The prototype would use a precision flow sensor (or load-cell calibration where appropriate) with an ESP32/STM32-based controller to measure each pour, automatically stop at configurable volumes (30ml, 45ml, 60ml, etc.), and log every event with timestamp, volume, and unique spout ID. The device would sync data to a cloud/backend API that integrates with supported POS platforms for transaction matching, inventory reconciliation, and reporting. The system would also support offline buffering so no pour data is lost during network interruptions. For the MVP, I'd deliver: Smart pourer firmware with auto-stop functionality Accurate pour tracking and calibration tools Backend API and secure database POS integration layer (depending on the POS system you use) Dashboard/reporting for usage and stock reconciliation Prototype documentation, testing, and future manufacturing recommendations A few questions before we begin: Which POS system(s) must the prototype integrate with? Is the auto-stop controlled by a solenoid valve or another dispensing mechanism? Do you want Wi-Fi, Bluetooth, or both for connectivity?

Love the idea of a smart pourer that actually talks to the POS — that's the kind of real-world problem that makes this project exciting. I've built similar IoT prototypes with auto-stop and liquid tracking, so this is right up my alley. → Built a solar-powered RFID water vending machine with precise litre metering and quota tracking → I'll deliver a working prototype with auto-stop, pour logging, and POS integration → Looking at roughly $250 for this, with a prototype ready in a 3 days. Happy to jump on a chat and see if we're a good fit. No pressure.
