The FIBIAC - a 3D printed electromechanical computer-> 0

Submitted by Brietech on Saturday May 12, @05:06PM

Brietech writes ""Behold the FIBIAC! Its loud! It computes! It uses actual punch cards!" The FIBIAC is a simple, stepper-motor based, (mostly) 3D-printed electromechanical computer. The program is stored on a loop of paper punch-cards, and the machine uses three, 3-digit electromechanical counters for storage (which could be expanded to support more complicated programs) Watch it in action computing the Fibonacci sequence, or jump on Thingiverse and build your own!"

Homebrew working Cray-1-> 0

Submitted by Brietech on Monday August 30 2010, @11:16PM

Brietech writes "This is a working binary-compatible, cycle-accurate 1/10th-scale Cray-1A, completely reverse-engineered from the hardware reference manual. The machine boasts 4 kilo-words of memory, a 33 MHz clock speed and its own tiny, pleather sitting-area. This fully-pipelined, 64-bit 1970's era supercomputer can peak at 3 floating point operations per second!"

Homebrew Microcontroller Laptop-> 0

Submitted by Brietech on Monday March 16 2009, @10:39PM

Brietech writes "This is a homebrew laptop project based on a Picaxe microcontroller. It has 16kb of RAM, 256kb of storage, sound and a self-hosted development environment! It has a simple CLI, file-system, 'E-maxe' text editor and a programming language called "Chris#." Oh, and yes, it runs Linaxe =)"

DIY 1980's Supercomputer-> 0

Submitted by Brietech on Friday February 20 2009, @12:11AM

Brietech writes "Ever wanted to own your own supercomputer? This guy recreated a 31-processor SIMD Supercomputer from the early 1980's called the "Non-Von 1" in an FPGA. It uses a "Non-Von Neumann" architecture, and was intended for extremely fast database searches and artificial intelligence applications. Full-scale models were intended to have more than 1,000,000+ processors. It's a cool project for those interested in "alternative" computer architectures, and yes, full source code (Verilog) is available (along with a python library)."

DIY Laptop literally from scratch!

Submitted by Brietech on Monday March 05 2007, @04:17AM

Brietech writes "Ever felt like building your own laptop from (almost literally) scratch? This is a microcontroller-based "laptop" built from the ground up from a handful of chips and other hardware found lying around. It runs a self-hosted development environment, allowing the user to write and edit programs in "Chris++" on the machine, and then compile and run them. The carpentry looks like it could use some work, but it's a neat project!"
