Sancai Maker
Mechanical engineers, electronics engineers, and software engineers work as one unit — from whiteboard concept to tested prototype. Small team. Serious NDA. Fast turnaround.
Start Your Project



From concept to working prototype — we cover the entire hardware development chain.
Structural design, mechanism design, FEA analysis, tolerance stack-up, and manufacturing-ready drawings in SolidWorks/STEP format.
Schematic design, PCB layout, component selection, prototype assembly, and testing. Power electronics, motor drivers, sensor interfaces.
Firmware development, embedded Linux, RTOS, PLC programming, and host-side applications. C/C++, Python, ladder logic.
Rapid prototyping with FDM/SLA 3D printing, CNC-machined prototypes, and PCB fabrication. Form, fit, and function validation.
Full assembly, wiring, calibration, and functional testing. Bug fixing, iteration, and validation before handoff.
All projects covered by NDA from day one. Full IP transfer on completion — drawings, schematics, source code, BOMs, and documentation.
From first conversation to delivered prototype — structured, transparent, and milestone-driven.
Define functional goals, constraints, and budget.
Technical analysis, proposed approach, and quotation.
NDA signed, project formally initiated.
Mechanical + electronics + software in parallel. Milestone reviews.
3D printing / CNC / PCB fabrication. Rapid validation.
Full assembly, functional testing, bug fixes.
Drawings, schematics, firmware, source code, BOM, and operation manual.
A selection of recent R&D projects (client details redacted under NDA).














Industrial control equipment, intelligent instruments, robotics actuators, UAV payloads, IoT devices, and custom mechatronic systems. Describe your functional goal and we'll assess feasibility.
A mutual NDA is signed before any project details are shared. All development is closed-loop; no code or drawings are shared externally. Secure file transfer via encrypted channels.
Yes. Mechanical design, electronics, and software are each available as standalone engagements. You can also start with one module and expand the scope later.
Mechanical drawings (SolidWorks / STEP), PCB schematics and Gerber files, embedded source code, BOM, and commissioning documentation. All IP belongs to the client.
Yes. We communicate in English and Chinese, and have experience delivering to clients in Europe, North America, and Southeast Asia. Time-zone-friendly meeting schedules available.
Three models: Fixed-scope project delivery (lump sum), long-term technical partnership (retainer), and milestone-based sprints (pay per milestone). Choose what fits your workflow.
Depends on scope. A simple PCB + firmware project: 4-6 weeks. A full mechatronic system with mechanical + electronics + software: 8-16 weeks. We provide a detailed timeline before starting.
We focus on R&D and prototyping. For production, we can recommend trusted manufacturing partners and help with the production handoff, including test fixtures and QC procedures.
Describe your project — we'll tell you if it's feasible and how we'd approach it.
