About this gig
I will turn your electronic product idea into a working prototype with 3D enclosure design, electronics design, and firmware programming.
From portable devices to custom controllers, I can help develop a prototype based on your requirements.
My services include:
- Custom 3D enclosure design and CAD modeling
- Electronic circuit design and component selection
- Microcontroller programming and firmware development
- PCB design when included in the agreed scope
- 3D printing, assembly, and functional testing
- Product renders and editable source files
Please send your idea, required functions, dimensions, and any sketches or reference images. If you already have hardware or code, I can help integrate it into your prototype.
Deliverables may include CAD files, circuit schematics, firmware source code, and an assembled working prototype, depending on your order.
Contact me before ordering so we can confirm feasibility, scope, component costs, fabrication, delivery time, and shipping. Pricing depends on the complexity of your project.
