A fierce man who turned a 'Linux PC' into a business card appeared

Many people have focused their wisdom on making unique business cards, and some have made '

business cards that can be used as USB memory'. Meanwhile, business cards with the minimum components required for PCs, such as CPU and memory, have appeared.

The business card for Linux-based PCs was created by embedded system engineer George Hilliard. On the surface, it says 'This card runs Linux!' Along with the profile. In addition, an IC chip is installed at the bottom of the business card, and you can see that the business card itself is used as a single board.

The back side looks like this. One corner of the card is a USB terminal, and when connected to a PC, it is possible to access the storage where Mr. Hilliard's resume and face photo are stored. You can also run the

shell through the virtual serial port to play the game Rogue or 2048 , run the UNIX program fortune that randomly displays quotes, and use the MicroPython interpreter for programming language processing. ... apparently ...

The breakdown of the material cost per sheet

is $ 1.42 (about 155 yen) for the Allwinner SoC F1C100s , $ 0.8 (about 87 yen) for the printed board, $ 0.17 (about 18 yen) for the 8MB flash chip, and other components. Is $ 0.49 (about 53 yen) for a total of $ 2.88 (about 315 yen), which is cheap for one PC. However, since it is handmade, it takes time and effort, and 'I do not intend to distribute it to everyone I met for free.'

Hilliard used a reflow oven called Puhui T-962 for soldering. At the time of writing the article, it can be purchased at Amazon.co.jp for 96,079 yen, which is quite cheap as a reflow oven.

Hilliard said, 'I've taken full advantage of my experience in embedded Linux machine and printed circuit board design. It's not perfect, but I think it's pretty good. And the project itself has been a good experience. I said.
