I’m sourcing a manufacturer-developer who can turn my supplied 3- to 5-minute MP3 tracks into a simple, plug-in mantra chanting box. The look I want is clean and minimalist—no ornate casing, just an unobtrusive unit that blends into any small altar or bedside table. Because these will stay permanently connected to mains power, there is no need for batteries. Key functional points: • Standard playback quality is fine; clarity matters more than audiophile specs. • A smooth volume control wheel or slider must be included. • The track should loop automatically, so a built-in repeat mode is essential. Scope of this run: – 200 finished pieces, each loaded with a different mantra that I’ll provide in MP3 format. – All units must pass a quick bu...

The design should use parts that I can actually buy from LCSC. All ICs and other important non-generic comp...

I have a draft schematic that still needs a proper electrical check before it can turn into a physical board. Your job is to verify the circuit, then create a clean, compact surface-mount layout in KiCad, keeping every component part number strictly within Lioncircuits’ in-stock catalogue. This board is for prototyping, so fast, trouble-free assembly is the priority. Once the circuit is validated, please route with sensible clearances, add test points where useful, and optimise the board outline for cost and signal integrity. Feel free to flag any footprint or availability issues and suggest substitutes from the same stock list. Deliverables • Corrected KiCad schematic • KiCad PCB layout files • Gerbers, drill & pick-and-place files ready for fabrication ...

Several new residential and commercial developments are moving into detailed design and I need seasoned MEP professionals from Pakistan to produce the full mechanical, electrical and plumbing design and planning package. Your work will focus exclusively on design—no installation or maintenance tasks are expected—so deep experience with AutoCAD, Revit MEP or similar tools is essential. Because the projects range from small villas to mid-rise mixed-use buildings, you will be expected to size HVAC systems, lay out electrical distribution, specify plumbing networks and ensure everything complies with local PEC guidelines as well as good international practice. Collaboration will be remote, but familiarity with regional suppliers and standards will make reviews and approvals faster...

I need a specialist who can turn more of my existing traffic into paying customers. My priority is clear: increase sales and conversions.

I need a fresh PCB layout for a new consumer-electronics gadget I’m developing. The board has to stay as compact as possible while still accommodating a double-layer stack-up for tighter routing and reliable grounding. I will give you the exact schematic, component library, and mechanical envelope; you translate that into a clean, manufacturable Gerber package plus a BOM ready for assembly. Design for easy pick-and-place, respect my keep-out zones, and keep trace widths and clearances within standard FR-4 limits so the board can be produced by mainstream fabs without extra cost. I’ll review the first pass in Altium (or KiCad if you prefer) and send any tweaks, then we lock the final files and fabrication notes. Deliverables are: • Source project files • Gerb...

Our plant is expanding its capacity with a new suite of CNC lathes, milling centres and auxiliary machining equipment. I need skilled technicians who can handle the complete installation and initial setup of this industrial machinery—from unloading and positioning through electrical, pneumatic and coolant hookups, alignment, levelling, calibration and first-run testing. The shop floor is already prepared with foundations, power drops and air lines; what’s missing is the hands-on expertise to make each machine production-ready while respecting manufacturer tolerances and our internal safety standards (ISO 45001). Experience reading mechanical and electrical schematics for machining centres is essential, as is familiarity with FANUC or Siemens controllers for basic parameter c...

I’m building a battery-powered prototype around an ESP32-S3 and need a rock-solid wiring diagram before I assemble anything. Once we start, I will share a complete list of sensors and modules, but you can assume they will be driven from a 9 V rail that must be stepped down where necessary. My priority is clear pin assignments, clean power routing, and reliable level-shifting so every device behaves exactly as intended. Your task • Draw a schematic / wiring diagram that shows every connection between the ESP32-S3, the sensors, any required regulators or level-shifters, and the battery interface. • Specify the exact GPIO pins you choose for each signal and explain any rationale or constraints. • Indicate decoupling, protection components, and connector types where...

I am building an integrated volt-ampere meter that also serves as a protection and control module for a pump system. The unit must: • Measure voltage and current accurately while reacting instantly to high/low-voltage and over/under-current conditions (these three protections are the top priority). • Manage a water-level subsystem that reads three stainless-steel probes plus one flow sensor, then drives two relays—one energises the starter circuit, the other keeps the motor running. Scope of work 1. Circuit and PCB: create the full schematic around a MindMotion MM32G0001A1T (or any other MM32 in the same family so our inventory stays unchanged), layout a compact single-board solution, and specify a CC display already stocked in-house. 2. Firmware: write clean, well-docume...

I have a small desk clock with a beautiful vintage edge-lit display, a bank of mechanical relays, and an Arduino doing the time-keeping. Unfortunately my first build was amateur—cold joints everywhere, wires stuffed into screw terminals, no strain relief.... Then a housemate dropped it. A friend at a makerspace has begun soldering bulbs in the propper layout to match the display but only completed the bulbs for 1 digit. They also started a ribbon connector for the bulbs to the relays/arduino/power section. I’d like you to finish the bulbs, get them connected, then cleanup the Arduino/gps-receiver/power section so it's mounted and ready for a case. I already 3d printed the display mount. • Flawless soldering on every connection, preferably on tidy perf-boards or a ...
