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.
