Compact Business Card Secretly Plays Old School Computer Startup Tunes
In the world of business networking, standing out from the crowd can be a challenge. However, one innovative solution is gaining traction - programmable PCB business cards. These cards, equipped with LEDs, buzzers, and custom programming, offer a unique and memorable experience.
One such example comes from [VCC], who has developed a low-cost PCB business card that not only plugs into a USB port for power but also plays over ten minutes of cracktro music through a small buzzer. The card is adorned with over a dozen small LEDs, adding a visual element to the interactive experience.
To optimise the assembly process, [VCC] 3D-printed a jig to apply material to the back of the USB connector on the card, ensuring a secure fit in the USB port. [VCC] also wrote a script for assembly-line programming of the cards, reducing the programming time to approximately ten seconds per card.
Despite these additions, the cost of the PCB business card remains unchanged, making it an affordable option for distribution. The final per-unit cost, including the 3D-printed jig and script, remains at 1.5 euros.
This trend in programmable PCB business cards is not limited to [VCC]'s creation. Creatively designed cards that integrate LEDs, buzzers, and custom programming are becoming increasingly popular. For instance, designer Jeremy Cook developed PCB business cards that incorporated an LED and a coin cell battery holder, making the card light up. Other designs include tools like rulers and protractors on the PCB itself, adding functionality beyond just contact sharing.
These designs often feature custom firmware to control the LEDs' behaviour or buzzer sounds, making the card more engaging and unique. While explicit examples combining all three features—LEDs, buzzer, and custom programming—are less common in the mainstream, the general trend includes the use of LED driver ICs, simple microcontrollers, and compact battery holders for self-power.
For those looking to create or explore such PCB business cards with custom programming, resources from PCB manufacturers and hacking communities provide project ideas and guidance on fabrication options, including vibrant solder mask colours and flexible or transparent PCBs for creative expression.
In conclusion, the future of business networking may well be interactive and memorable, thanks to the rise of programmable PCB business cards. With their low cost and high potential for customisation, these cards offer a unique opportunity to make a lasting impression.
- The programmable PCB business card developed by [VCC] not only features LEDs, buzzers, and custom programming but also includes a script for assembly-line programming, reducing the programming time significantly.
- In the realm of programmable PCB business cards, designs like those by Jeremy Cook, incorporating LEDs and battery holders for self-lighting, and those with integrated tools such as rulers or protractors, are becoming more prevalent, offering functions beyond mere contact sharing.
