Expertise

At DEV Joni, we specialise in a wide range of manufacturing, design, and software techniques to create vertically integrated, well performing products. Wherever it adds the most value - such as in product architecture, critical software, and precision hardware - we develop in-house to maintain high customisability, performance, and originality. While we inevitably rely on global supply chains for components like micro-controllers and raw materials, our focus is on owning the parts of the process that define product quality and performance.

This page showcases the core capabilities behind the products we build. All our products can be customised to meet your specific needs, and if you get and idea, we’re always open to developing something new - especially when it can be shared openly and made commercially available to others.

We generally don’t take on fully custom project work because we may have to charge a lot compared to what is finally delivered, just to cover the development costs. Truly custom-made development can get expensive, especially when the result is highly specific and not useful to anyone else.

By focusing on reusable, adaptable product platforms, we are able to spread development costs across many customers - so each one gets more capability, better performance, and a more sustainable solution for their money. We occasionally make exceptions for fully custom work, but we usually don’t recommend it unless there’s a strong case. We really want you to feel that you received great value for your investment.

Our Expertise

We bring together a unique blend of skills to create versatile, high-quality products:

• Software Development: Rapid prototyping and development mainly in Python.
• 3D CAD Design: Using OpenSCAD to design precise, customizable parts.
• Electronics Integration: Assembling and controlling electrical components.
• Scientific Expertise: Hands-on knowledge in neuroscience and electrophysiology to guide product design.

Manufacturing Techniques

Our in-house manufacturing capabilities include:

• 3D Printing: Primarily using PETG for durable, accurate parts.
• Electronics Assembly and Soldering: Skilled assembly and soldering of electronic components to ensure reliable, high-quality circuit integration.
• Optical Parts Casting: Creating clear lenses tailored to specific needs - utilising our vacuum chamber to remove bubbles and ensure optical clarity.
• Basic Wood and Metalworking: Skilled hand craftsmanship and use of hand-held power tools for drilling, cutting, and shaping parts with precision.
• Metal Casting: Casting techniques for complex metal components - supported by our kiln for precise heating and burnout processes.
• Basic Metallurgy and Custom Alloys: We have the ability to develop and cast our own aluminum mixes to tailor material properties for specific needs
• Vacuum Chamber: Used to degas resins and improve casting quality by eliminating air bubbles.
• Kiln: Essential for controlled heating during metal casting and material curing processes.
• Professional Air Spray Painting: Using compressor-driven spray equipment to apply smooth, even, and durable paint finishes.
• Surface Polishing: Manual and mechanical polishing techniques to achieve refined, high-quality surface finishes on a variety of materials.
