Printable Pad: Pocket Sized Notebook by EclairM0
In a pocket-friendly size comparable to a Tic Tac container, a captivating DIY project known as the EclairM0 offers a potent blend of simplicity and functionality. The device, submitted by [Matt], showcases a nostalgic throwback to early cellphone texting days, meticulously documented for easy replication.
The EclairM0's firmware is penned in TinyGo, an unfamiliar yet ideal choice for microcontroller projects battling storage constraints. The device sports a 14-button input, mirroring old-school phone keypads, with multi-tapping and combo key presses catering to a variety of functions. A 0.91-inch 128x32 yellow OLED display is a noteworthy highlight, enhanced for swift response time by optimizing the screen's performance.
Battery considerations led to the selection of a slim 3mm thick power source, but the additional 2mm from the battery protection circuitry necessitated a design adjustment. [Matt] strategically relocated the protection circuity to the main PCB to maintain the device's original slim profile.
Weighing merely 15 grams, this lightweight device runs on a SAMD21 microcontroller, ensuring USB host functionality, enabling the EclairM0 to double as a keyboard, mouse, or other USB peripherals. Housed within a 3D-printed case, the project's open-source nature unlocks design and firmware files accessible via GitHub, making customization and experimentation seamless for enthusiasts.
Our appreciation for petite, handheld DIY projects continues, and the well-documented, engaging EclairM0 fits right in. For those eager to create their own, [Matt] offers detailed instructions on his dedicated page [1].
