I am Chanaka Prasad, Founder and CEO of Idea8, a product development and engineering company specializing in hardware, robotics, IoT, embedded systems, automation, and AI-enabled product development. At Idea8, we help startups, manufacturers, and product companies turn ideas into working prototypes, MVPs, pilot systems, and production-ready solutions. Our team combines electronics, mechanical design, firmware, PCB design, 3D design, software, AI, and manufacturing support under one roof, which allows us to move faster and solve problems end-to-end instead of handing work between disconnected freelancers. What we can help you build: ✅ Hardware product prototypes and MVPs ✅ IoT systems, dashboards, and connected devices ✅ Robotics and automation systems ✅ PCB design and embedded firmware development ✅ ESP32, STM32, Arduino, Raspberry Pi, Jetson, and custom electronics ✅ Machine vision and AI inspection systems ✅ UAV, rover, and robotic platform development ✅ 3D CAD design, enclosure design, and 3D printing ✅ Manufacturing-ready product development and supplier support Our approach is simple: we do not just “build what is asked.” We first understand the product goal, technical risk, cost target, user environment, and manufacturing path. Then we design the right engineering solution with the correct balance between performance, budget, timeline, and scalability. We are especially strong in projects where hardware, software, firmware, mechanics, and real-world testing need to work together. Many product development projects fail because each part is built separately. Idea8 solves this by managing the complete development process from concept to working prototype and beyond. Core technical capabilities: • Embedded systems and microcontroller programming • Firmware development using C, C++, Python, and related tools • PCB design, schematic design, and electronics integration • IoT platforms using ThingsBoard, Blynk, cloud dashboards, and custom web apps • Robotics, automation, motor control, sensors, and actuator systems • Computer vision, AI inspection, and real-time data systems • SolidWorks, 3D CAD, mechanical design, and enclosure development • 3D printing, rapid prototyping, testing, and product iteration If you are looking for a team that can think like engineers, execute like product builders, and communicate clearly like a long-term technical partner, Idea8 can help. We are best suited for clients who need serious engineering execution, not just basic task completion. Whether you are building a new hardware product, improving an existing system, automating a factory process, or developing an IoT/robotics solution, we can support you from the first prototype to a manufacturable product. Let’s build something real.

As a proactive electronic engineer with ten years of experience in the industry, I offer complete solutions to bring your ideas to life.

3D Industrial Designer & Product Designer & PCB Designer | Fusion 360 · SolidWorks · Rhino · KeyShot | Electronics Enclosure Design | Medical Device Designer | Wearable Device Designer | Mechanical Engineering and Mechanical Engineer | DFMA | Photorealistic Rendering | Startup Product Designer and Industrial Design I take industrial products from concept sketch to manufacturing ready CAD without the redesign cycles that push launch timelines back by months. If your product is going to a toolmaker, a contract manufacturer, or a regulatory submission, it leaves my desk ready to act on, not ready to revise. I work with hardware startups, consumer electronics brands, medical device companies, and wearable device teams. The common problem across all of them is the same: engineering that looks complete on screen but breaks down the moment it reaches production. Draft angles missing. PCB clearances off. Wall thickness inconsistent. BOM not tied to the model. I solve that problem at the concept stage, before it becomes a tooling invoice. WHO I WORK WITH Hardware startups need a product design partner who is thinking about manufacturing from the first sketch, not after the prototype comes back broken. The startup that brings me in early saves three to five weeks on a typical product launch timeline. The startup that brings me in after the prototype fails pays for two development cycles instead of one. Consumer electronics brands need DFM ready CAD that does not come back from the toolmaker with a correction list. I deliver electronics enclosure geometry toleranced for connector positions, mounting boss alignment, and thermal management from day one, not corrected after a failed first prototype. Medical device design teams need DFMA applied at the concept stage, technical drawings with full GD&T, and a Bill of Materials that is production ready before the model is finalized. I do not retrofit manufacturing discipline onto a finished model. I build it in from the first feature. Wearable device companies need mechanical design precision, electronics enclosure engineering, and ergonomic geometry working together in a single manufacturing ready package. I have delivered wearable device housings where the PCB fit, the user interface geometry cleared, and the toolmaker had zero queries on receipt of the files. ELECTRONICS ENCLOSURE DESIGN AND PCB ENCLOSURE Every electronics enclosure I deliver is built around the PCB it houses. I start with the PCB mechanical envelope, work outward through the user interface geometry, and close with a DFM ready CAD model your contract manufacturer can act on the same day they receive it. PCB enclosure geometry designed without mechanical discipline produces fitment problems at assembly. Connector positions off by half a millimeter. Mounting bosses that strip on first assembly. Thermal paths blocked by the housing geometry. My electronics enclosure design process eliminates those problems before the first prototype is cut. INJECTION MOLD DESIGN AND DESIGN FOR INJECTION MOLDING Design for injection molding is not a checklist I run at the end of a project. It is a first principle I apply from the first feature of every model. Draft angles, consistent wall thickness, gate position logic, parting line geometry, and sink mark prevention are built into my concept design workflow, not added when the model is already finished. My DFMA process catches production problems at the CAD stage before they become tooling changes at $800 to $2,000 per engineering change order. DFM ready CAD from my desk means your injection mold design goes to the toolmaker with zero surprises and a technical drawing package that answers their questions before they ask them. MANUFACTURING READY CAD AND TECHNICAL DRAWINGS Manufacturing ready CAD is not a clean 3D model. It is a 3D model where every feature has been evaluated against the manufacturing process, draft for injection molding, flat patterns for sheet metal, print orientation for rapid prototyping, and a drawing package that includes full GD&T tolerancing, surface finish callouts, material specifications, and revision control formatted to the standard your contract manufacturer expects. I deliver manufacturing ready CAD and technical drawings as an integrated package. The model and the drawing are in sync. There are no version control problems between them because they are developed together, not separately. BILL OF MATERIALS AND PRODUCT DEVELOPMENT A complete Bill of Materials is the commercial bridge between your CAD model and your supply chain. Every product development engagement I take to a launch milestone includes a structured BOM with manufacturer part numbers, approved alternates, quantities, and cost flags on long lead components. The BOM is built in parallel with the manufacturing ready CAD so your sourcing team can start moving while the model is still being finalized. Let's build something worth manufacturing.
