Location : Paphos, Cyprus (preferred) · Remote from Limassol also fine Compensation: €1,500 total across 3 milestones Type: Freelance / side project · Flexible hours ----- ## What we’re building A consumer countertop appliance that automatically prepares a powder-based beverage — heating water, dosing, agitating, and dispensing a finished drink at the press of a button. Think single-serve coffee machine, but with completely different physics under the hood. We’re a Cyprus-based startup at the prototype stage. The product architecture and industrial design are defined. We need hands-on help turning the design into a working physical prototype. ## What we need An electronics / embedded systems person to help build the prototype across three paid milestones: ### Milestone 1 — Component Selection & BOM (€200) - Review the design specification and system architecture - Research and source exact components: water pump, heating element, temperature sensors, motor drivers, solenoid valve, power supply, connectors - Deliver a complete Bill of Materials with supplier links and pricing - ~10–15 hours of work ### Milestone 2 — Breadboard Functional Prototype (€600) - Wire all subsystems on dev boards and breadboard around an ESP32 - Get the microcontroller communicating with every component: pump, heater (PID temperature control), motor, sensors, display - Implement a basic state machine for the full preparation cycle - Deliverable: it heats, pumps, agitates, and dispenses — ugly but functional - ~50–60 hours of work ### Milestone 3 — Integrated 3D-Printed Prototype (€700) - Mount electronics into 3D-printed enclosures (we handle the CAD and printing) - Clean wiring with proper connectors and cable management - Full brew cycle running end-to-end, reliable and repeatable - Deliverable: a demo-ready unit you could put on a table and show to people - ~50–60 hours of work Each milestone is paid on completion. You can stop after any milestone — no long-term commitment required. ## Who this is for - EE / mechatronics / embedded systems student or recent graduate - Hobbyist or maker with real hands-on electronics experience - Someone comfortable with: ESP32 / Arduino, soldering, reading datasheets, basic PID control, wiring motors and sensors - You do NOT need: PCB design, firmware architecture, or product design experience — we handle that This is a great portfolio project if you’re a student looking to work on a real product, not a class assignment. ## Requirements - All work is under a simple work-for-hire agreement with IP assignment — standard for any product development project - Ability to meet in person in Paphos is a strong plus (workshop available) - Must be able to communicate in English ## Interested? Send a short message about your background and any projects you’ve built (even hobby/personal projects count). No formal CV needed.
