I’m ready to move an industrial-grade controller from concept to production and need a designer who has already shipped tight, 6-layer boards. The board must host a main microcontroller, its support circuitry, and several high-current power-regulator stages, all within a restricted outline while meeting EMI/EMC limits typical for factory environments. You’ll start from my block diagram and rough schematic notes, turn them into a production-ready layout, and supply every file the assembly house will ask for: updated schematics, stack-up, Gerbers, drill files, pick-and-place, BOM, and a brief design report explaining how the EMC strategy and size targets were achieved. I’ll be available for rapid feedback on component placement and routing choices, and we’l...

I need a complete design for a compact consumer-electronics board that revolves around a PIC microcontroller. The scope spans three tightly-linked parts: • PCB hardware – Produce the schematic and multilayer layout in Altium Designer, include all libraries you create, and deliver the full manufacturing package (Gerbers, drill files, pick-and-place, and a PDF schematic). -PCBA implementation with JLCPCB Acceptance criteria – Board passes electrical rule checks and is ready for fabrication without edits. I will provide exact sensor part numbers, preferred connectors, and enclosure dimensions after kickoff; you are free to choose regulators, clocks, and protection components so long as you stay within a 3.3 V rail and keep the BOM cost-effective.
...readings that make the data unusable. What I need is a clean, reliable way to sense those isolated DC voltages without tying the reference points together. Whether that means introducing isolated amplifiers, optocouplers, tiny transformers, or another proven technique is up to you; I’m open to whichever approach gives stable, repeatable results and keeps the measurement side safe for the microcontroller. Here’s what I’d like back: • An updated schematic that drops into my existing design, showing every connection required for proper isolation • A concise parts list with recommended component values and footprints I can actually buy today • A short rationale explaining how the proposed stage cures the isolation problem and what accuracy I ca...

I’m open on the exact platform; ESP32, Raspberry Pi Pico W or any microcontroller you feel suits a child-safe, low-power product will work. The finished prototype should be safe, responsive and easy to extend with new activities as the curriculum grows. Let me know which sensors, wireless protocol and development tools you prefer, how quickly you can deliver a working prototype, and any previous child-focus...
...software to life. On the hardware side, the priority is circuit design. I will share detailed functional blocks, power-budget targets, and regulatory constraints; you would translate these into a clean schematic that is ready for board layout (I will also welcome help on the actual PCB routing once the schematic is locked). For software, I need both the embedded code that will run on the microcontroller and the on-screen user interface logic that appears on the TV. Simplicity and reliability for elderly users are the guiding principles. You should feel comfortable choosing an appropriate MCU, writing efficient firmware in C/C++, and prototyping a straightforward, large-font on-screen menu in a framework that can later be ported to the final hardware.

I already have raw .bin images that flash and run correctly on the Silicon Labs SI4010 RF transmitter, but I now need production-ready software that lets me interact with the chip over SPI from a host microcontroller. Here is where things stand today: • The hardware is proven, the SI4010 is wired for SPI, and I can load binaries through the existing programmer. • What is missing is the firmware layer (or host-side driver, if you prefer) that will expose reliable SPI commands so I can configure registers, inject payloads, and trigger transmissions programmatically. What I expect from you: 1. Clean, well-documented C (or C++) source that compiles in Simplicity Studio or any GCC-based toolchain compatible with the chip. 2. A concise header/API that my applicatio...
I am building an embedded feature around an MRS Electronics controller, part number 1.107.110.00, and I need clean, portable C firmware written specifically for this board. The code has to run directly on the microcontroller, so please follow embedded-system best practices: no dynamic memory, tight timing awareness, readable state machines, and clear separation between hardware-abstraction layers and application logic. I will provide the detailed register map and functional requirements after kickoff; however, expect typical tasks such as configuring peripherals, servicing interrupts, and exchanging data over the existing communication bus. Compile-time options must allow me to toggle individual features because the same image will later be scaled to multiple variants of this har...

I am building an intelligent virtual instrument around an NI USB-6008 DAQ and LabVIEW to watch a DC motor for trouble in real time. The system must acquire temperature, vibration, voltage and current, then flag abnormal behaviour and log it for later review. The two fault families I care about most are temperature spikes and vibration anomalies, so your design needs to give these channels priority in sampling rate, signal conditioning and alarm logic. Voltage and current tracking can share the remaining bandwidth but still need to be visible on the same front panel. What I need from you • A LabVIEW VI (source + executable) that interfaces cleanly with the NI USB-6008, auto-detects connected sensors and streams all four signals on a unified dashboard. • Configu...

The interface can be Bluetooth, Wi-Fi, or another practical wirel...
I have a batch of legacy *.tdms files generated in LabVIEW. In each file there is a single channel whose data needs correction: at a predefined set of sample indexes I will supply, the existing values must be replaced with new ones. All other channels, properties and file-level metadata stay untouched. The workflow I picture is: open the original file, patch only the targeted indices inside the specified channel, then save the result as a new file (same name plus a suffix is fine) so that my original data remains intact for traceability. Essential requirements • LabVIEW-based solution using the native TDMS API (no external converters). • Reads a tdms file list of index–new-value pairs. • Preserves channel and group properties exactly as found. ...

Boxing Speed & Reaction Time Trainer (Wokwi Project) I just built a Boxing Speed Test Simulator using Wokwi — a browser-based microcontroller simulator that lets you prototype and test circuits without physical hardware. This project is designed to give a simple reaction time training setup inspired by how boxers measure punch speed and reflexes: -> Random light cues appear on LED indicators -> You have to press the correct button as fast as you can -> Time and accuracy feedback is printed to the serial monitor Why this matters: In boxing, faster reaction time and correct hits dramatically improve performance — hitting first and accurately can change the outcome of a bout. How it works: • Four LEDs light up in a random order • The user must ...
