[CERCO] Maker/Electronic Engineer per prototipo gioco

@AITSoft

Buongiorno, posso supportarvi nella realizzazione del Proof of Concept del gioco educativo, dalla definizione dell’architettura elettronica fino all’assemblaggio dei componenti nella base e nei tasselli. Imposterò una soluzione con Arduino o ESP32, valutando sensori di prossimità, sensori magnetici o tag passivi in base a precisione, ingombri, robustezza e facilità di integrazione nei materiali leggeri. Svilupperò lo schema dei collegamenti e un firmware Arduino commentato, con gestione affidabile dei LED RGB per segnalare posizione e orientamento dei pezzi. Presterò particolare attenzione a cablaggio nascosto, alimentazione, consumo, modularità e semplicità di manutenzione, così il prototipo potrà essere testato e modificato rapidamente. Posso inoltre collaborare all’assemblaggio e organizzare brevi incontri in zona Milano/Pavia, se utili. Sono disponibile a sottoscrivere un NDA prima di ricevere i dettagli riservati. Per definire correttamente la soluzione, Quanti tasselli dovranno essere rilevati simultaneamente e l’orientamento richiede una precisione assoluta o solo alcune posizioni predefinite? Resto disponibile per confrontare i requisiti e impostare insieme il primo prototipo.

Hi there, I carefully reviewed your educational-game prototype requirements, including the use of Arduino/ESP32, proximity or magnetic sensing, RGB LED feedback, and the physical integration of electronics inside a compact game base and lightweight pieces. I am a mechatronics engineer with almost half a decade of experience in embedded electronics, hardware prototyping, electronic board design, sensors, and system integration. My background is well suited to developing the hardware architecture, selecting suitable sensing methods, and building a practical Proof of Concept with attention to both the electronics and mechanical integration. I am also comfortable working under an NDA before receiving the confidential functional details. Since I am based in Tunisia, the collaboration would primarily need to be remote unless the in-person requirement can be arranged separately. Please send me a message so we can discuss the project and start. Best regards, Samuel tshibangu

@yaroslavmark

Hi, I have experience developing Arduino/ESP32 prototypes that integrate proximity/magnetic sensing, addressable RGB LEDs, embedded firmware, and compact electronics for interactive devices. I have completed systems with 10+ sensor/LED channels, custom PCB/protoboard integration, and fully documented hardware/firmware suitable for functional proof-of-concept validation. Approach ✅ I will define the sensing method for piece position/orientation using Hall sensors, reed switches, NFC/RFID tags, or another suitable passive solution after reviewing the game mechanics. ✅ I will build the Arduino/ESP32 hardware architecture, LED feedback logic, power distribution, connectors, and commented firmware with clear state handling for each game piece. ✅ I will optimize the electronics for hidden installation beneath the rigid base and lightweight cardboard pieces, then validate detection reliability, orientation recognition, and LED response timing. Questions ✅ How many pieces must be detected simultaneously, and must the system identify only presence/position or also each piece’s unique identity and orientation? ✅ What are the approximate base dimensions, maximum thickness available for hidden electronics, and expected battery or mains power source? Best, Yaroslav

@hamzazayyad

Hello, I reviewed your educational game prototype and I’m interested in the combination of embedded electronics, sensors, and interactive LED feedback. I am based in Jordan, not in the Milan/Pavia area, so I would not be able to attend regular in-person meetings. However, I can handle the complete electronics and firmware development remotely and support the physical assembly through clear wiring diagrams, documentation, and video calls. I have 15+ years of experience in embedded systems, PCB design, and microcontroller programming, including STM32, PIC, ESP32, and Arduino-based projects. I can provide: • Hardware architecture and complete wiring schematic. • Selection and integration of magnetic/proximity sensors or passive tags. • RGB LED control based on piece position and orientation. • Reliable firmware with clearly commented source code. • Compact wiring and component integration suitable for the game base and lightweight pieces. • Prototype assembly guidance, testing, and debugging. I am also comfortable working under an NDA before receiving confidential details about the commercial concept. If remote collaboration is acceptable, I would be happy to discuss the required number of pieces, sensing method, and expected prototype behavior. Best regards, Hamza

Having read through the description of your project, I am confident that my skills and expertise in Arduino, Electronics, Embedded Systems and Microcontroller align perfectly with what you need. My name is MOHD SADAB and for years I have been building AI systems and custom IoT hardware - making functional prototypes is my speciality. I have successfully handled PCB design tasks as well as firmware development on platforms such as ESP32/STM32. Thus, I am fully equipped to deliver a highly functional and well-integrated game prototype for you. Notably, my experience spans across diverse sectors - healthcare, manufacturing, agriculture, etc. I'm familiar with designing sensor networks and integrating them seamlessly within existing frameworks (like what your project requires) while delivering real-time actionable insights. Working on MQTT-based solutions has given me appropriate competence to handle how data flows from sensors to the game controls. My real strengths lie in delivering tangible results; from proof of concepts to actual production infrastructure. This positions me ahead because I understand the need for an effective interplay between the hardware (the game components you mentioned) and software components of your educational game especially when it comes to cost-efficiency without compromising quality. So, let's materialize this unique project together: effective infrastructure combined with a fantastic educational premise!

@electronicsdone

Dear Client, Yes—this is feasible, but the real challenge is not simply connecting an Arduino/ESP32 to sensors and LEDs. The critical part is reliably detecting each game piece’s presence, position and orientation while keeping the electronics compact, hidden and robust inside the base and lightweight pieces. PCB Must Innovations brings 30+ years of electronics experience across embedded systems, Arduino/ESP32, sensor integration, LED control, custom electronics, prototyping and hardware validation. Profile: https://www.freelancer.in/u/electronicsdone I can own the complete PoC: Arduino/ESP32 selection, proximity/magnetic sensor or passive-tag detection, hardware wiring, RGB LED control, schematic, component selection and prototype assembly guidance. The amateur trap is making one sensor and one LED work perfectly on the bench, then discovering that ten pieces inside a real game board have different detection behavior. Haha, prototypes have a funny way of exposing assumptions. I’m happy to offer a free consultation first so we can define the number of pieces, detection method, board dimensions, LED arrangement and game logic before hardware is finalized. One question: approximately how many individual game pieces must the system detect simultaneously? Message me with that answer and I’ll outline the cleanest sensor, electronics and firmware architecture and milestone path before you commit. Kind Regards Prat PCB Must Innovations

@maksymstel

Hello I am a Full Stack Engineer with 10 years of experience, providing Arduino, ESP32, sensor integration, RGB LED control, embedded firmware, and prototype development. In my opinion, the best approach is to build the prototype around a simple, reliable sensor architecture that can detect both the presence and orientation of each game piece. The ESP32 or Arduino can then process these inputs and drive the RGB LEDs with clear visual feedback while keeping the electronics compact enough to hide inside the base and pieces. This project is very similar to my previous works. I have developed embedded prototypes using ESP32/Arduino, proximity and magnetic sensors, LEDs, and custom control logic. I am also experienced in turning early concepts into practical, testable hardware prototypes. The most important skill is embedded hardware and firmware integration, because the sensors, piece detection, and LED feedback must work together reliably. I will design the wiring and firmware with clear comments so the system can be easily modified during testing. So, I will divide your project into three major steps. 1️⃣ Define the sensor architecture, components, wiring, and detection logic. 2️⃣ Build and program the Arduino/ESP32 prototype with sensor processing and RGB LED feedback. 3️⃣ Test the complete system and support the physical integration into the game base and pieces. I will provide the creative idea and good tech solution for your project. Best regards. Maksym

@hexabitzprojects

Hi, Sono interessato a sviluppare il **prototipo funzionante del gioco educativo** e posso occuparmi sia dell’elettronica sia del firmware. Ho **16 anni di esperienza in R&D elettronica ed embedded**, lavorando con **Arduino, ESP32, sensori, LED RGB, PCB personalizzati e sistemi interattivi/IoT**. Ho sviluppato dispositivi compatti in cui sensori, microcontrollore e feedback visivo devono funzionare in modo affidabile e con firmware non bloccante. Per il vostro PoC posso progettare lo **schema hardware, selezionare la soluzione più adatta tra Arduino ed ESP32, gestire sensori magnetici/prossimità o tag passivi e controllare i LED RGB** in base alla posizione e all’orientamento dei pezzi. Posso inoltre preparare **firmware Arduino/ESP32 ben commentato, schema di collegamento, logica di rilevamento e istruzioni di assemblaggio**, mantenendo l’elettronica compatta e facilmente integrabile nella base e nei tasselli. Sono disponibile a collaborare a distanza e, se necessario, a brevi incontri in presenza concordati. Sono anche disponibile a firmare un **NDA prima di ricevere i dettagli riservati del progetto**. Posso condividere esempi di miei precedenti progetti embedded/IoT e discutere insieme la soluzione più semplice per il primo prototipo. Best regards, Subhash Suman Embedded Electronics | Arduino | ESP32 | Sensors | PCB | Firmware

@alfatrade2

Con i sensori magnetici la presenza si rileva facilmente, l'orientamento no, perché serve un magnete a polarità codificata o due sensori Hall per tassello. Lavoro da remoto, quindi schema e firmware li faccio io, ma la saldatura del prototipo dovrebbe farla qualcuno sul posto. Ho scritto firmware C/C++ per microcontrollori con sensori e controllo di attuatori, anche su RP2040. Quante posizioni ha la base e quanti tasselli?

@engruhulajom

Buongiorno, sono un Top Rated Full-Stack Developer con oltre 10 anni di esperienza nello sviluppo software, sistemi interattivi e integrazioni hardware/software. Posso supportare lo sviluppo del PoC con un approccio ordinato e orientato a un prototipo realmente funzionante. Ho compreso che il progetto richiede Arduino/ESP32, sensori di prossimità o magnetici/tag passivi e LED RGB per fornire feedback in base alla posizione e all’orientamento dei tasselli. Posso occuparmi della logica software, firmware, gestione degli input e feedback LED, oltre alla documentazione del collegamento e all’organizzazione del codice. Le mie competenze includono C#, Java, Python, JavaScript, sistemi interattivi, debugging e sviluppo software. Ho tre domande: i. Preferisci Arduino o ESP32? ii. Quali sensori hai già scelto? iii. È disponibile un primo schema del gioco? Sono disponibile a valutare i dettagli dopo NDA e definire insieme tempi e compenso. Best regards, Md Ruhul Ajom

@hamzaePCB

Prima di definire l’hardware, chiarirei quattro punti che determinano direttamente l’architettura del prototipo: • Quanti tasselli deve riconoscere la prima versione? • È necessario identificare solo la posizione oppure anche l’orientamento di ogni tassello? • I tasselli devono essere completamente passivi, senza batteria? • Qual è la distanza prevista tra il sensore sotto la base e il tassello? In base a queste risposte valuterei la soluzione più semplice e affidabile tra magneti/sensori Hall, reed, RFID/NFC o un’altra tecnica di identificazione, evitando di complicare inutilmente il primo Proof of Concept. Per il controller, ESP32 sarebbe una buona base se sono previste future funzioni wireless; Arduino può invece essere sufficiente se il primo prototipo deve gestire solamente rilevamento e feedback RGB. Posso occuparmi dello schema hardware, selezione dei componenti, collegamenti, firmware commentato e, se utile dopo la validazione del prototipo, anche della progettazione PCB. Un punto da chiarire: lavoro principalmente da remoto e non sono attualmente nella zona Milano/Pavia. Posso comunque supportare la progettazione, il firmware e l’assemblaggio guidato da remoto. Se la presenza fisica è obbligatoria, preferisco chiarirlo prima di procedere. Sono disponibile a firmare un NDA prima di ricevere i dettagli riservati del gioco.

@Aaleen110

The primary technical risk is integrating multiple proximity/magnetic sensors and passive tags accurately within a rigid base and game tiles for reliable detection. I will build this by using an ESP32 for its processing power and Wi-Fi capabilities, connecting the RGB LEDs and chosen sensors via I2C or SPI protocols, and developing the firmware to manage the dynamic visual feedback. This will result in a working prototype of your educational game. What is the power source you envision for the prototype? Provide me with the exact dimensions and materials planned for the game base and tiles. My work here has earned a 5.0 rating across 10 reviews on this platform, also securing Preferred Freelancer status.

@SkillCrafts

I've successfully developed interactive prototypes for educational games, similar to your requirement for a proof-of-concept using Arduino or ESP32. My experience includes integrating various sensors like proximity and magnetic readers to create engaging user experiences, ensuring robust and responsive interaction for young learners. My approach involves leveraging Arduino's extensive libraries and community support for rapid prototyping. I'll design a modular system for easy testing and iteration, starting with a core Arduino/ESP32 board. For the proximity/magnetic sensing, I'll evaluate Hall effect sensors or RFID/NFC tags based on the specific interaction fidelity and power requirements. I'll then develop firmware to manage sensor input, process game logic, and potentially drive simple haptic or audio feedback. To best tailor the solution, could you elaborate on the desired range and precision for the proximity/magnetic detection? Also, are there any specific power consumption constraints for the prototype? I'm eager to discuss how my technical skills can bring your educational game prototype to life.
