Just snap off the corners and this business card can be used as a mass storage device. Well sort of. The tab left over has four traces on the back to make it USB compatible. The PIC 24FJ64GB002 microcontroller on the card registers as a storage device and launches [Ramiro’s] resume and a cover letter loaded as an HTML file. He’s made it as useful as possible by including access to the SPI and I2C bus connections but he’s also included some firmware to act as a data logger or an oscilloscope. At about 5 euros a piece you won’t be distributing these willy-nilly but it’s not too much more than handing out breakout boards with your name all over them.
Embedded above is a neat augmented reality business card by ActionScript developer [James Alliban]. After seeing “the most impressive business card you will ever see“, he was inspired to update his own business card. His new card has a fiduciary marker on the backside and directs you to his site. A flash app on the site displays a video where he tells you more about himself. The 3D grid of planes in the video varies in depth based on the brightness of the section. He has a few more AR and tracking demos on Vimeo.
Updated: While we’re talking augmented reality, it’s worth checking out the tech behind ESPN’s baseball tracker that uses doppler radar.

Evil Mad Scientist Laboratories has released the 2313 target board. A business card sized development board for working with ATTiny 2313 microprocessors. We saw them at the Maker Faire, and thought they looked familiar. You may recognize them due to their similarity to the Atmegaxx8 family board. As usual, this is released as creative commons and source files are available on their site.
[John Park] has managed to snag a couple interesting business cards at Maker Faire. The first is Adafruit’s laser cut Spirograph card. The other is a ATtiny2313 prototyping board from Evil Mad Science; it looks to be the same style as their well-known AVR target board. We’ve also heard rumors that [Jérôme Demers] has bunch of resistor bending cards.

Evil Mad Scientist Laboratories has updated their business card AVR breakout boards to version 1.1. We suspect the changes will probably make them even more popular. The boards are designed for the ATmegaXX8 family of microcontrollers. The center has all 28 pins labeled while either end has a prototyping area. An in-system programming header is also provided. For the new version, both prototyping areas have been increased to accommodate DIP14 packages. The holes for the microcontroller are now larger so that they can hold a ZIF socket. Finally, the power and ground traces have been expanded. We’ve always like the versatility of these boards, as demonstrated in the Tennis for Two project, and can’t help wondering if these updates were made to facilitate another project.
This mini web server is slightly smaller than a business card. There are a lot of tiny one-board servers out there, but this is probably the smallest you can etch and solder at home. Unlike many embedded web servers, files are stored on a PC-readable SD card, not in a difficult-to-write EEPROM. Read on for the web server design, or catch up on PIC 24F basics in the previous article: Web server on a business card (part 1).

For years, Microchip PIC microcontrollers dominated; PIC16F84 hacks and projects are everywhere. The 8-bit 16F and 18F lines are supported by several coding environments and easy-to-build serial port programmers. Microchip’s 16-bit PIC24F is cheaper, faster, and easier to work with, but largely absent from hacks and projects.
We recently used a Microchip PIC24F microcontroller in a mini web server project, but didn’t find many introductory references to link to. In this article we’ll cover some PIC 24F basics: support circuitry and programming options. We’ll also talk about our favorite features, and how we figured them out. Our next article will outline a web server on a business card based on the PIC 24F.
