Fully Automated 2kg Tabletop Roaster Design

@Mahihassi

My journey as a dedicated Electrical Engineer with a Master's in Embedded Systems has equipped me with the expertise you need for your fully automated tabletop coffee roaster. My comprehensive knowledge of microcontrollers like STM32, ESP32, Raspberry Pi, and Arduino make me adept at firmware development and IoT product engineering. I genuinely understand your need for utmost reliability and accuracy without compromising safety interlocks, and I assure you that my skillful hands can deliver exactly that. With an all-encompassing approach to product development, I am equipped to offer not just the control architecture, wiring diagrams or the firmware/software execution you need but also the bench-tested proof that your system can carry out complete roast-cool cycle for a 2kg load without manual intervention. I have a keen eye for fine-tuning user interfaces, ensuring touch-friendly layouts for onboard screens in addition to providing detailed Bill of Materials with readily sourced components, testimony to my dedication towards thorough documentation. In conclusion, my dexterity across various technologies including IoT Connectivity, Robotics & Control, Biomedical Instrumentation and CAD & Mechanical Design will uniquely position me to incorporate your selected mechanical drawings and sensor specs seamlessly.

HI, KINDLY READ THROUGH MY PROPOSAL I will deliver a complete, reliable, and fully automated control system for your 2 kg tabletop coffee roaster executing pre-set and user-editable roast profiles with precise coordination of temperature, drum speed, and timing from warm-up through cooling, including onboard touch UI and remote monitoring via USB, Bluetooth, and Wi-Fi. MY APPROACH ✅ Phase 1: Finalize control architecture, safety interlocks, sensor integration, and profile definition format. ✅ Phase 2: Develop robust firmware/software with profile execution engine, real-time PID temperature control, drum speed control, data logging, and multi-connectivity (USB + BLE + Wi-Fi). ✅ Phase 3: Design clean touch-friendly UI, bench-test full roast-cool cycles, and provide complete documentation + BOM. DELIVERABLES • Control architecture + detailed wiring diagrams • Complete firmware/software with profile management and logging • Touch-friendly onboard UI layout • Full BOM with readily available components • Bench-tested prototype validation + documentation package QUESTIONS 1. What sensors are already selected (thermocouples, RTDs, drum speed encoder, etc.)? 2. Preferred main controller platform (Raspberry Pi, STM32, ESP32, or other)? 3. Any specific roast profile format or maximum number of steps per profile? Ready to start immediately. I can provide a solid, repeatable solution that ensures consistent results batch after batch.

Hello, I can help design and develop the complete control system for your fully automated 2 kg tabletop coffee roaster. My background is in industrial automation, SCADA, IIoT, embedded systems, machine integration, sensors, control logic, data logging, and digital transformation projects in real industrial environments. My proposed approach is to create a reliable control architecture using a suitable microcontroller/SBC or PLC-based solution depending on your selected sensors, heaters, fan, drum motor, and safety requirements. The system will execute editable roast profiles from warm-up to cooling, controlling temperature, drum speed, timing, fans, and safety interlocks. The deliverables can include: • Control architecture and wiring diagrams • Firmware/software for automated roast profiles • Data logging over USB, Bluetooth, and Wi-Fi • Touch-friendly UI layout for the onboard screen • BOM with practical and available components • Safety logic for heaters, fans, sensors, emergency stop, and fault handling • Documentation for setup, testing, and future updates Before starting, I would review your mechanical drawings, selected sensors, heater/fan specifications, motor driver details, preferred controller type, and required UI screen size. I can deliver a practical, well-documented, and expandable automation solution suitable for consistent hands-free roasting. Best regards, Mohamed M.
