Hack. Keyboard. Arduino. Pdp11. 8008. Craft. Craft is a demo running on its own minimalistic demo platform. The demo platform is based on an ATmega88 microcontroller. Having successfully built a soundchip out of a microcontroller together with my friends in kryo, I wanted to tackle the greater challenge of generating a realtime video signal along with the sound.

Here's the Pouët page for Craft. How does it work? Just like your average 80's home computer, the entire design is centered around the timing of the video signal. A typical VGA-based, low-resolution CRT monitor will redraw the screen 60 times per second using an electron beam, which is sweeping across the screen one line at a time. Music Video Schematics. A PIC16F84 Introduction. Modular Motherboard. An ambitious group of hardware hackers have taken the fundamental building blocks of computing and turned them inside out in an attempt to make PCs significantly more efficient. The group has created a motherboard prototype that uses separate modules, each of which has its own processor, memory and storage.
Each square cell in this design serves as a mini-motherboard and network node; the cells can allocate power and decide to accept or reject incoming transmissions and programs independently. Together, they form a networked cluster with significantly greater power than the individual modules. The design, called the Illuminato X Machina, is vastly different from the separate processor,memory and storage components that govern computers today. “We are taking everything that goes into motherboard now and chopping it up,” says David Ackley, associate professor of computer science at the University of New Mexico and one of the contributors to the project. Norair agrees. Computer made of logic gates. Magic-1 is a microcoded minicomputer running at 4.09 Mhz and is in the same ballpark as an old 8086 in performance and capabilities. It supports user and supervisor modes, address translation via a hardware page table, six external interrupts and up to 8 MB of memory (currently has 4 MB).
Each process has up to 128 Kbytes of addressing, broken down as 32 pages (2K) of data and 32 pages of code mapped via the page table onto the 23-bit physical memory and device spaces. Here's a picture of it running before the enclosure arrived. The physical address bus is 22 bits (though effectively 23 because of a signal line which selects between memory and device spaces). The data bus is 8 bits wide, and internal CPU data paths are 16 bits. ALU operations work on both 8 and 16-bit operations, and there are 256 opcodes. Because this is a microcoded machine, each of the instructions causes the execution of a microcode subroutine. Magic-1 started off as a pure one-address accumulator machine. Software. Building Your Own Web Server. The Elements of Computing Systems. Japanese geeks offered smaller-than-Eee little laptop. Japanese laptop maker Kohjinsha has rolled out a pair of Eee PC challengers, taking on the elfin sub-notebook with a pair of similarly sized tablet-style units incorporating 80GB hard drives.
Kohjinsha's SA5KXO8AL: watch out, Eee PC Fortunately, neither the SA5KXO8AL and SA5KXO8FL run Windows' Tablet PC Edition - they come pre-loaded with XP Home Edition instead. The operating system runs on the machines' 500MHz AMD Geode LX800 processor, which is backed with 512MB of 333MHz DDR 2 memory and said HDD. Tilt... Like the Eee, the Kohjinsha SCCs (Small, Cheap Computers™) sport 7in, 800 x 480, LED-backlit displays, though here they're mounted on a swivel to allow them to be used tablet-fashion.
The new sub-notebooks measure 218 x 163 x 25.4mm - all slightly less than the Eee's dimensions. But the Eee's lighter: 890g to 945g. ...and swivel The Kohjinsha SCCs have 802.11b/g Wi-Fi and 10/100Mb/s Ethernet for connectivity. Kohjinsha claims the units' battery is good for up to five hours' runtime.
