Custom Bluetooth TrackPoint Mouse (Assistive Device)

@Mahihassi

We are MHTechFusion, a Germany-based IoT/embedded systems team (5–7 engineers) experienced in custom HID devices, BLE firmware, and compact hardware design. Our approach: • TrackPoint Integration: Interface genuine ThinkPad TrackPoint via ADC/I2C (depending on module), with fine-tuned sensitivity for low-force input • BLE HID Mouse: Use ESP32 (C6/S3) or Nordic nRF52 for stable macOS-compatible HID (no drivers needed) • Click Control: Single external switch with proper debouncing (press/hold/release logic) • Power System: LiPo battery + USB-C charging (TP4056/BQ series) + power management • Enclosure: Compact, ergonomic 3D design ensuring stability during press Optional enhancements: • Adjustable sensitivity (via firmware or config mode) • Tremor smoothing (simple filtering + motion dampening) • Firmware source + future upgrade support We will deliver a fully assembled, tested device ready to pair with MacBook. A couple of quick points: • Do you already have a specific TrackPoint module in mind? • Any size/ergonomic preference for the enclosure? We can share a phase-wise plan (design → prototype → testing) after a quick alignment. Looking forward to working on this impactful solution. – Sardar (CEO MHTechFusion)

HI, I can deliver a clean SketchUp to STEP conversion by rebuilding geometry into precise solid CAD—ensuring smooth surfaces, correct topology, and a fully usable file for manufacturing or engineering workflows. 1️⃣ What is the model complexity (simple parts or detailed/organic geometry)? 2️⃣ Do you need direct conversion or full CAD remodeling for accuracy? 3️⃣ Which software will you use next (SolidWorks, Fusion 360, etc.)? Warm regards, The Blend Nation

As an electronic hardware and firmware engineer with expertise in embedded systems and PCB design, I am ideally positioned to tackle your custom Bluetooth TrackPoint Mouse project. My experience includes developing reliable, high-performance PCBs, designing efficient LED driver circuits, and programming various microcontrollers. These skills will directly translate into an excellent understanding of how to integrate the TrackPoint module into the electronics of your device and ensure the cursor movement is both responsive and adjustable. In addition, my proficiency in implementing wireless technologies like Bluetooth will guarantee seamless connectivity with your MacBook without the need for any additional drivers. I am also at ease working with rechargeable battery systems and can incorporate a USB-C charging port for convenience. Furthermore, I have a solid grasp of Solidworks which could be valuable in creating a small, stable enclosure that houses the electronics and guarantees easy access to both the TrackPoint module and external switch. Lastly, I want to underline my commitment to cost-effective solutions without compromising performance or deadlines. Your project is aimed at reducing physical effort when using a computer and it's a noble undertaking that aligns with my values.

Hi, KINDLY READ THROUGH MY PROPOSAL THIS IS WHAT I WILL DO - Design a complete, compact custom Bluetooth mouse around the ThinkPad TrackPoint module and a single external click switch. - Use a low-power Bluetooth SoC (nRF52840 or ESP32-S3) for native HID mouse compatibility on macOS (no drivers). - Implement smooth cursor movement with adjustable sensitivity and basic tremor smoothing if needed. - Add reliable single-button left-click support (press = click, hold = drag, release = release). - Include LiPo battery + USB-C charging with proper protection. - Provide full KiCad schematic + PCB layout, BOM, firmware source code (PlatformIO/Arduino), 3D enclosure model suggestions, assembly guide, and test procedure. RELEVANT PROJECTS - 2025: Custom low-force TrackPoint-based assistive mouse for accessibility (nRF52840 + LiPo) – delivered design + firmware. QUESTIONS - Do you already have a spare ThinkPad TrackPoint module, or should I include sourcing guidance? - Preferred size / enclosure style? - Any preference for nRF52840 or ESP32-S3? I can deliver the full design package in 6–10 days.

As an electronics specialist, my expertise lies not just in designing and building but also in 3D printing. This unique combination of skill sets makes me the ideal candidate to create this custom Bluetooth TrackPoint mouse for you. I am proficient in using SolidWorks for accurate design and have successfully designed and printed intricate mechanical parts even for industrial machines. This mouse project is nothing short of a challenge I am excited to take on. I totally understand the importance of ease in using assistive devices, which is why I'll meticulously design a small, stable enclosure for the electronics incorporating the ThinkPad TrackPoint module. My aim would be to respond to your low force requirements effectively, so cursor movement becomes completely hassle-free. Additionally, your preferred single external switch placement and clean, functional design will be incorporated perfectly balancing aesthetics and function. Pairing flawlessly with your MacBook via Bluetooth and functioning like a standard HID mouse are non-negotiables for me. I have ample experience working with different connectivity modules and can assure complete compatibility. Lastly, I strongly believe in empowering clients through knowledge, thus I will provide transparent instructions for pairing and charging as well as extend any help with the source code or firmware post-delivery if needed.

Best Assistive Bluetooth Mouse Design Specialist ⭐⭐⭐⭐⭐ Hi, Creating a custom Bluetooth TrackPoint mouse isn’t just about assembling components—it’s about delivering a smooth, precise, and low-effort user experience. With an assistive device like this, even small inconsistencies in cursor movement or click response can significantly affect usability. The key challenge in this project is ensuring that the TrackPoint input feels natural and responsive, while the single-switch click mechanism remains reliable and easy to use. At the same time, the device must maintain stable Bluetooth connectivity, efficient power usage, and a compact, practical form factor. My approach focuses on building a well-integrated system: accurate TrackPoint signal handling, clean and consistent click response, reliable Bluetooth HID performance with macOS compatibility, and efficient battery + USB-C charging design—all packaged into a stable and user-friendly enclosure. Before getting started, I’d like to clarify a couple of things: 1. Do you have a preferred microcontroller, or should I select the most suitable option for Bluetooth stability? 2. Would you like the enclosure to be customized ergonomically for a specific user or kept more general-purpose? Feel free to message me—I can walk you through similar device designs and how I would deliver a reliable, comfortable, and production-ready assistive solution. Best regards, Prat PCB Must Innovations
