That's right, we're calling all engineers and makers from India and ASEAN countries (Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, Vietnam) to showcase their creativity and innovation to win up to $5,000 in prizes. Whether it's a simple DIY Solar charger or a wind turbine-powered treehouse, we're looking for projects that will blow our minds and save the planet.

We want to see projects that are sustainable, eco-friendly, innovative, and darn right cool! So, put on your thinking caps, grab your tool kits, and join us in this challenge to create a greener and brighter future for us all.

This contest is brought to you by DigiKey and CircuitDigest to motivate you to build sustainable projects by leveraging the wide range of components available with Analog Devices, Microchip Technology, STMicroelectronics, Raspberry Pi, and Espressif Systems.
