Linux Computer is One P.H.A.T. USB Stick

A start-up firm in the French Alps put together one Pretty Hot And Tempting USB stick. This one only has 256MB of memory, but IS a full working computer.

Based off an Atmel processor this SoC (System-On-Chip) design has a 190MHz processor, 64MB RAM, 256MB of memory, USB connectivity and a 10/100 Ethernet port.

The company, Calao, didn’t give a price tag but did mention some useful applications like GPS and image processing.

I for one saw that lovely USB connector and immediately thought of the new Samsung USB monitors and wondered if this is our future of computing.

Not only is the Calao Linux computer PHAT it’s also fat. Measuring at 3.3 inches long and 1.4 inches wide it is much larger then your average UFD…but also clear there is nothing average about this concept.

The biggest claim: non-technical folks can get their hands into USB driver development with little or no previous experience with USB. Simply edit an INF file and configure the USB stack to perform just about any function you desire.

Now, I’m no programmer, but have been around enough that I know nothing is quite this easy. None-the-less, with the popularity of USB, development kits such as the Kithara USB toolkit is a welcomed sign.
