I’m developing Wendz, an ultra-slim, wall-mounted vending kiosk that also serves third-party advertisements on a 4 K screen. The unit will pair that display with a 10-inch touchscreen for product selection, a four-slot spiral vend mechanism, UPI/NFC payments, 5 G/LTE connectivity, a full sensor suite for health, security and usage, active cooling for true 24/7 operation, plus an emergency stop that triggers a cloud-based escalation flow. The brief covers the entire journey: mechanical, electronics and firmware design, through to a deployable pilot and a first run of roughly ten identical machines, complete with bill of materials, assembly documentation and field support. Time is critical—I want to move now and see the first working unit on-site as soon as possible. Bengaluru collaboration is ideal, but I’ll prioritise depth of kiosks, vending or IoT hardware experience anywhere. Deliverables • End-to-end design package (CAD, schematics, firmware, cloud integration) ready for compliance testing • One fully functional, wall-mountable pilot meeting every spec above • Repeatable BOM and build instructions enabling a short run of ten units • Fabrication, assembly and validation of that initial batch • Post-deployment support to resolve any field issues during early rollout Acceptance will be based on on-site testing of every core function—advertising playback, vend-on-touch, cashless payment, sensor reporting, remote health monitoring and emergency-stop escalation—operating reliably for a 24-hour cycle. When you reply, please lead with past work that shows comparable hardware you’ve shipped and supported; that proof will weigh most heavily in selection.

Hello, I reviewed your requirements, and the core challenge is integrating the mechanical design, vending system, electronics, firmware, connectivity, and cloud infrastructure into a reliable kiosk architecture that can transition smoothly from a working pilot to a repeatable production build. Every subsystem needs to be developed with manufacturability, serviceability, and long-term field reliability in mind so the first deployment accurately reflects the design intended for the initial production run. I have been involved in complex product development and prototype design projects and can share relevant examples once we connect in chat. Also a quick question, has the four-slot spiral vending mechanism already been selected, or should its dimensions and drive system be defined as part of the overall product architecture?

Wendz is a serious piece of hardware — 4K advertising, spiral vending, UPI/NFC, 5G, active cooling, and a cloud-triggered emergency stop. That’s a full-stack IoT system, not a weekend prototype. I’ve shipped exactly this kind of integrated machine before. → Designed and deployed a custom smart snack vending machine with cashless payments, custom PCB, MDB protocol integration, and real-time inventory monitoring — live in production. → I handle the full stack: mechanical CAD, PCB layout, firmware, cloud backend, and assembly documentation → First working unit on-site in 2–3 days, with BOM and build instructions for your ten-unit run For this scope, the cost would be $300. Happy to walk you through our approach and past work on a chat.
