Description: We are developing a prototype of a motor control system based on an existing PCB that uses an ATmega16 microcontroller. The current system controls the speed and torque of the main motor and the speed of a secondary motor. Inputs are presently taken from a custom-made keyboard with tactile push buttons, and motor control is achieved by pulling specific GPIO pins high or low in defined sequences. The objective of this task is to replace the physical keyboard input system with a capacitive touch LCD display, where the on-screen UI buttons will perform the same functions as the existing tactile buttons. The touchscreen interface will control motor on/off, speed, and torque, while ensuring that the existing motor control logic based on GPIO sequences remains functionally the same....
I need a fully-working firmware for an "Adafruit RP2040 board USB Type-A host" that can sit between a wired gaming mouse and the PC. Its job is to spoof the original mouse’s VID, PID, serial number and any other required descriptor bytes so the operating system believes the orginal mouse is of a different brand. Key behaviour • Gaming mice are the priority, but the solution should fall back gracefully with most common wired models. • All native packets from the mouse must pass straight through untouched, so the user experiences zero latency or feature loss. • At the same time the firmware has to expose its own composite HID interface that lets me inject cursor movement, click events and scroll actions programmatically. Implementation expectations ...

I already have the full schematic and the finished PCB files for a board that combines an ESP module with a PIC18F microcontroller. What I’m missing is a clear, practical explanation of how everything talks to each other, especially over UART, and how that interaction is implemented on the physical board. Here is what I need from you: • A step-by-step walkthrough of the signal paths that handle UART traffic between the ESP and the PIC18F, including any level-shifting, buffering, or hand-shake lines that support the link. • A guided tour of the PCB layout that shows where those signals travel—layer changes, vias, ground references, decoupling, and any routing choices that affect integrity or noise. • Simple notes on any supporting circuitry (power rails, ...
I've already built some prototypes of a circuit capable of switching a single 230 V, 16–30 A line to 4, 8, or 12 outputs—without power loss—but none of them have reached the standards I expect. I have schematics, calculations, thermal measurements, and test logs: enough material to clarify every technical detail and speed up your work. I need a senior designer who can transform all this into a final solution, complete with ESP32 firmware, a multilayer PCB (4 or 6 layers, JLCPCB production - 3oz copper), and an accurate and documented simulation before production. Technical requirements to be met: • Maximum energy efficiency, component protection, and precision switching under load. • Integrated remote control, real-time monitoring, and an alarm system. &b...

Mi occorre un progettista senior che sappia trasformare tutto questo in una soluzione definitiva, completa di firmware su ESP32, con PCB multilayer (4 o 6 strati, produzione JLCPCB - copper 3once) e una simulazione accurata e documentata prima della produzione. Requisiti tecnici da rispettare • Massima efficienza energetica, protezione dei componenti e precisione nella commutazione sot...
I’m replacing my existing pool circulation unit with a single-speed pump that I already have on site, along with all the fittings, unions, and electrical hardware required. The pad is clear, the plumbing is exposed, and access from the driveway to the equipment area is wide open, so getting tools and materials in place will be straightforward. What I need is a qualified installer who can: • Plumb the new pump into the current PVC line, ensuring airtight, leak-free unions • Make the electrical connection to the existing breaker, verify correct voltage, and bond/ground to code • Prime, test-run, and fine-tune the flow so the system reaches full pressure without cavitation • Leave the pad clean and walk me through basic operation once everything is running sm...

The task is to design a compact PCB that drops straight into an SCX 1/32 car so it can run on a digital track. I want the board to read the track’s reed-sensor signal, let me assign any of 20 unique car IDs in firmware, and expose a surface-mount USB-C port on the edge for easy flashing once the body shell is back on. Size must stay close to the original analogue board footprint (about 24 × 18 mm, height under 6 mm) but I can adapt mounting holes or connector positions if you have a cleaner layout idea. Power comes from the standard track pickups (nominal 14–18 V DC), so include an efficient buck or LDO to feed the microcontroller and reed circuitry. I haven’t locked the MCU yet; pick anything small, inexpensive, and easy to program—ATmega, STM32, ESP32, or s...

I’m building a small bionic butterfly that “flips” in mid-air, powered by an ESP32-S3 Super Mini. What I still need is the full control system: firmware for the board plus a cross-platform mobile app that drives two micro-servos through a joystick interface. Here’s the flow I’m picturing: • The ESP32-S3 runs custom firmware (Arduino IDE or ESP-IDF—whichever you prefer) advertising itself over BLE. • The mobile app—working on both Android and iOS—connects, shows a virtual joystick, and streams position data in real time. • The board translates that data into precise PWM signals so each servo can beat the wings smoothly and synchronously. I will supply the hardware (ESP32-S3 Super Mini and servos) for your testing if nee...

I have individual, validated firmware blocks for the STM32L432KBU6 that handle an LIS3DH accelerometer (interrupt-driven), an EM4095 RFID front-end, the MCU’s internal touch-sensing controller, and a UART-based E220-400T22S LoRa module. My next step is to merge these routines into one cohesive, ultra-low-power application on our custom PCB. Power optimisation is the top priority. I want the system to remain in STOP mode most of the time, waking through the LIS3DH interrupt and periodic RTC events. When active, each peripheral must communicate reliably without compromising the sleep budget. Key points • Integrate existing C-based drivers into a single project • Configure and test the STOP-mode strategy, ensuring wake-ups from both the LIS3DH and the RTC function every t...

Abstract: Manufacturing-Ready 130nm CMOS Inverter Design The objective of this project is to design, verify, and prepare a standard CMOS inverter for fabrication using the SkyWater 130nm Open-Source PDK. Unlike theoretical projects, this work follows a complete "Silicon-to-GDS" flow. The process begins with Schematic Capture and Pre-Layout Simulation to establish electrical baselines. This is followed by Physical Layout, where the geometric structures of the NMOS and PMOS transistors are manually drawn according to strict foundry Design Rule Checks (DRC). The design is then validated through Layout vs. Schematic (LVS) to ensure physical-electrical equivalence. Finally, Parasitic Extraction (PEX) is performed for Post-Layout Simulation to account for real-world wire resistance and...

I already have a working PCB built around an Xsens MTi-630 IMU and an NXP MKV56 microcontroller. What I need now is a technician who can revise the existing firmware so the remote camera head delivers rock-solid motion compensation on set. Your task is to design and embed a custom sensor-fusion routine that blends gyro, accelerometer, and magnetometer data from the MTi-630, then feed that fused orientation into the motor-control loop over CANopen. I’m aiming for a balanced mix of speed and accuracy so operators never feel lag yet still enjoy drift-free performance during long takes. You will be starting from my current codebase (MCUXpresso / NXP SDK), which already handles basic hardware abstraction and CANopen messaging. The focus is on: • Writing or adapting a quaterni...
