In the realm of DIY electronics, Toby Chui, an Instructables user, embarked on a mission to create a custom power bank that not only delivers a powerful 60W output but also boasts a real-time information display. Join us as we delve into the journey of this remarkable project, a testament to human ingenuity and the joy of creation.
The Powerhouse Within: Unveiling the Core Components
At the heart of this DIY power bank lies a LiPo battery, the energy reservoir that breathes life into the device. A 60W PD module takes center stage, orchestrating the delicate dance of negotiations between devices, ensuring seamless power transfer. And to keep you informed, a UART HMI display serves as the eyes and ears of the power bank, presenting vital battery information at a glance.
Bridging the Information Gap: Sensing and Displaying Power Dynamics
To bridge the gap between the power bank’s inner workings and the user’s curious eyes, a small piece of perfboard, meticulously soldered and glued to the back of the display, plays a crucial role. This intricate circuit houses a buck converter, a voltage divider, and an ACS712 current sensor, acting as the sentinels of power flow. They tirelessly monitor voltage and current, relaying this vital information to the iRobota Nano, the brains behind the operation.
The Maestro of Data: iRobota Nano Takes the Stage
The iRobota Nano, a compact yet capable microcontroller, assumes the role of data maestro. It orchestrates the symphony of information, receiving voltage and current readings from the sensors and transmitting them to the display. Additionally, it keeps a watchful eye on the voltage delivered over the USB-C cable and calculates the total power consumption, ensuring you’re always in the know.
Encasing the Creation: A 3D-Printed Haven
To provide a secure haven for the power bank’s components, Toby Chui, with the precision of a sculptor, designed and 3D-printed a sleek case. This protective shell not only houses the battery, switch, and display but also lends an air of sophistication to the device, transforming it from a mere collection of components into a cohesive masterpiece.
