I need a plug-and-play USB dongle that quietly presents itself to the laptop as a standard HID mouse and then, without any host software, begins moving the pointer in truly random, human-like paths. Every travel should land on random points across the screen, never following a predictable grid or loop, and the velocity needs to ebb and flow so it looks as if an actual hand is guiding it rather than a script—variable speeds are essential. Because I will sometimes want to pause the motion or cycle through a couple of intensity presets, all adjustment must live on the device itself: a small tactile button (or a pair, if easier) that toggles the mover on/off and steps through, say, slow, medium, or fast randomness. No companion app, driver, or registry edits—just pure hardware control. I’m happy with any microcontroller that can enumerate as a USB HID device (ATmega32u4, RP2040, STM32, etc.) as long as you supply: • A fully assembled, tested dongle ready to ship • The firmware source and brief build instructions so I can re-flash if needed • A short user sheet showing what each button press does and the range of movement speeds The end goal is a discreet, reliable gadget I can trust to keep my machine awake while passing even the keenest “is someone there?” eye test.

Hello, I can design and build a plug-and-play USB HID dongle that emulates a standard mouse and generates natural, human-like random cursor movement without any host software. The device will use a reliable microcontroller (such as ATmega32u4 or RP2040) and include on-device buttons to toggle motion and switch between speed/intensity modes. The firmware will implement non-predictable motion paths with variable velocity profiles so the cursor movement appears realistic rather than scripted. I will deliver a fully assembled and tested dongle, complete firmware source code, and clear build/flash instructions. You will also receive a simple user guide explaining button controls and movement presets. The device will enumerate as a standard USB HID mouse, ensuring compatibility with Windows, macOS, and Linux. I can complete the prototype and testing within a few days.

I'm a Mechatronics and Robotics Engineer with hands-on experience building custom smart devices. I've worked extensively with microcontrollers like ATmega32u4 and RP2040. For your dongle, I would use an ATmega32u4 or RP2040 since they have native USB support without needing additional chips, which keeps the design compact. The firmware will generate random movement using algorithms like Perlin noise or Bezier curves so the cursor follows realistic arcs and natural paths across the screen instead of predictable straight lines. I'll also implement variable velocity with smooth acceleration and deceleration to mimic how an actual person moves a mouse. For hardware control, I'm planning two small tactile buttons mounted directly on the device: one for toggling the movement on/off, and another to cycle through speed presets (slow, medium, fast). No drivers or software installation required - it will enumerate as a standard HID mouse immediately when plugged in, with all logic running onboard. Deliverables will include a fully assembled and tested dongle ready for immediate use, complete firmware source code with reflashing instructions in case you want to modify the behavior later, and a user guide documenting button functions and speed mode characteristics. I can ship the finished unit via DHL or UPS to your location once testing is complete. The final design will be compact and unobtrusive when plugged into your laptop.
