POV Business Card Is Guaranteed To Get You Noticed

March 21, 2011 by Mike Nathan 17 Comments

Some say that handing out business cards is an antiquated practice due to the ubiquity of smart phones which can be used to trade or record contact information in mere moments. Instructables user [sponges] however, doesn’t agree and is pushing a “business card renaissance” of sorts with his POV business card.

Hand-built in his basement, the cards feature a handful of SMD LEDs that display his name, followed by his phone number when waved back and forth. Constructed to be nearly the same size as a standard business card, his verison uses a PIC to manage the display as well as a tilt sensor to monitor the card’s motion. His walkthrough is quite thorough, and includes tutorials for each of the steps required to build the card. He discusses constructing your own etching tank, converting a laminator for PCB transfer purposes, building a solder reflow oven controller, as well as hacking an aquarium pump for use as a vacuum-powered pick and place.

The end result is a sharp looking business card that ensures you won’t forget meeting him. Keep reading to see a video of the card in action.

Obligatory tech tree

It’s hard to let a Christmas go by without looking in on a geeky Christmas tree project. Luckily, [Peter Davenport] decided to share his Arduino and LCD shield tree.

Blinking USB dude

If you’ve got a 555 timer and some commonly salvageable components give this blinking LED man a try. The version above is USB powered but that’s just to take advantage of the 5V regulated power.

Propeller business card

[Jay’s] business card is packing quite a punch with this Propeller microcontroller. We love seeing electronics design in cards (however unrealistic the price and portability may be), and this is a big processing upgrade compared to the Tiny85 based offering.

Flying high in NYC

We leave you with a spectacular view of New York City. This breathtaking footage is just as fascinating as the first videos we saw from these folks.

Tiny USB Business Card

October 29, 2010 by Mike Szczys 43 Comments

[Frank Zhao] put together a USB business card. It’s even got the instructions printed right on the silk screen of the PCB explaining how it should be used. He based the design around an AVR ATtiny85 microcontroller. It runs the V-USB package that handles USB identification and communication protocols. The rest of the hardware is pretty standard, the uC draws power from the 5V USB rail, with a couple of 3.6V Zener diodes to drop the two data lines down to the proper level.

Once plugged in it waits until it detects three caps lock keypresses in a row, then spews a string of its own keypresses that type out [Frank’s] contact information in a text editor window (video after the break). It’s not as reusable as the mass storage business card because [Frank] didn’t breakout the pins on controller. But we still enjoy seeing business cards that make you stand out.

This is a great project to tackle with your newly acquired AVR programming skills.

Mass Storage Business Card

May 25, 2010 by Mike Szczys 28 Comments

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.

Augmented Reality Business Card

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.

ATTiny 2313 Breakout Boards From EMSL

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.

Business Cards At Maker Faire

[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.
