MicroSD Card-Sized Music Player Spins Old-School Video Game Tunes on the Go
In the realm of innovative technology, a new player has emerged, transforming the traditional business card into a multifunctional networking tool. [VCC], a creative mind in the field, has taken the PCB (Printed Circuit Board) business card to new heights with significant improvements in efficiency and affordability.
The PCB business card, a product that combines LEDs, a buzzer, and cracktro music, has been optimized for efficiency by [VCC]. The microcontroller at the heart of this device is an ATtiny1616, a cost-effective choice that offers enough outputs to drive the buzzer and LEDs.
One of the key advancements made by [VCC] is the optimization of the assembly and programming process. By writing a small script for assembly-line programming, [VCC] has reduced the programming process to approximately ten seconds per card. This automation has led to a more efficient production line, resulting in a final per-unit cost of just 1.5 euros before shipping.
The assembly process itself has also been optimized for efficiency. [VCC] has developed a jig for USB connector assembly, ensuring a secure fit in the USB port, and has even 3D printed a jig to increase the thickness of the USB connector's back for added security.
The PCB business card is not just a technological marvel; it is also designed to be a low-cost product. The cost of the ATtiny1616 microcontroller is under 50 cents, making it an affordable choice for this innovative device.
The PCB business card boasts over a dozen small LEDs that light up stars, and a small buzzer that plays over ten minutes of cracktro music. These features, combined with its practicality and affordability, make it a unique and engaging networking tool.
Notable examples of previous PCB business cards include Dennis Kaandorp's design featuring a 42 dual-color LED matrix (red/green) used to play Connect Four and Snake games, and Jeremy Cook's cards that incorporate functional tools along with contact info. These examples showcase the potential for creative and practical combinations on business cards.
[VCC]'s contributions to this field extend beyond just the PCB business card. Their work includes a jig for USB connector assembly and a script for efficient programming, making them a significant player in the world of innovative technology.
The PCB business card is powered through a USB port, making it convenient for use in a variety of settings. With its unique features and affordable price, it is a networking tool that is sure to make a lasting impression.
