    I have been working with PCBs for explosive gas environments, such as LPG filling plants, for about three years. This is where I gained the most practical PCB design thinking patterns and in-depth knowledge — including how to design highly sensitive PCBs while considering stack-up effects such as internal capacitance and inductance between layers. I have not seen any other course in Sinhala that delivers this level of practical and technical insight. This course goes beyond software tools and teaches advanced industrial-level design concepts. Highly recommend.

    The ESP32-S3 Gerbers came back from the fab first-try working. The stackup notes alone saved me two spins.

    සිංහලෙන් පැහැදිලි කිරීම නිසා PCB design එක ලේසියෙන් තේරුණා. The masterclass got my FYP board done in three weeks.

    The FOC firmware is genuinely production quality — clean HAL separation and the observer was already tuned.
