I want the running total revenue from my Shopify store to show on a Wi-Fi-enabled physical counter that sits on my desk. The job is to build the small bridge between Shopify’s JSON API and the hardware. Here’s what I already have and what I need from you: • Data source – Shopify: I only care about the store’s Total revenue figure. A lightweight call to the REST Admin API (or GraphQL if you prefer) is enough. I will supply the private-app credentials. • Destination – Hardware counter: It connects over Wi-Fi. You can target it with plain HTTP, WebSocket, or MQTT; whichever is simplest to flash onto a common ESP8266/ESP32 controller. I can handle the flashing if you give me the compiled binary or the Arduino/PlatformIO project. • Service layer:...

We are a hotel using a specific electronic door lock. We need to integrate these locks with our Property Management System (PMS) to automate keycard management. The lock company cannot provide an API or documentation, so we need to determine the communication protocol and build a custom interface.

I have an air-quality monitor prototype on breadboard and now need a production-ready PCB. The core of the board will be an Arduino Nano, linked to Wi-Fi for cloud logging and OTA updates. Only a particulate-matter sensor has to be integrated at this stage, but I’d like the layout to leave space and headers so a future gas sensor can be dropped in without a full redesign. What I expect from you: • Complete schematic, PCB layout and clean routing for the Nano, Wi-Fi module, particulate sensor, regulated power path (USB-5 V input and Li-ion option), plus an on-board antenna or footprint. • Clearly labelled break-outs for I²C, UART and an SPI port, and pads for an optional 0.96" OLED or similar display. • All design files (KiCad or Altium), Gerbers, dr...

I’m putting together a compact desk ornament that spins on command, and I need a complete PCB solution to drive the rotation reliably.

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...

I want to turn my stock WowWee MiP into a fully-independent companion with far more capability than the original phone-controlled toy. The big push is to give it functional robotic arms—servo-driven, proportional, and strong enough to perform simple pick-and-place demos—while keeping the self-balancing chassis intact. To drive everything, I need an internal “brain” (Raspberry Pi, ESP32, or another MCU you’re comfortable with) that can: • run onboard code without any phone connection • store multiple programs in flash so I can swap behaviors on the fly • process a forward-facing camera for navigation and object tracking • handle voice-command triggers and speak back in character using a small speaker For interaction I’m l...

I'd like to create a schematic and PCB layout that I can use to print from a photo I have. The layout is based on an ATmega and an ESP32, along with a servo connected to the ATmega. I'd like a guide on how to create a schematic file that I can modify and use in the future, not just the photos I have.

I have a production-ready, IGBT full-bridge welding inverter that already powers both TIG and MMA processes, yet the embedded side still needs a final expert pass before release. The control board is built around 8051 and STC MCUs running Keil C51 firmware, and every line of code directly shapes arc stability, HF start, AC balance, soft-start, and safety interlocks. The short-term goal: review, tidy, and extend the existing code so it drives the power stage flawlessly in TIG and MMA, AC and DC. That means refining PWM timing, gate-drive dead-time, current-feedback filtering, and all the little state-machine details that separate a decent welder from a great one. Core tasks and deliverables • Audit the present C51 codebase, flagging race conditions or timing pitfalls. • Im...
