DIY Laptop

Posted by Hemos on from the from-the-ground-up dept.

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!"

    an OS in 96 bytes of RAM? Bring it on!

    There is an interesting overview of guides to make a do-it-yourself laptop at Repair4Laptop. If you don't want to build it completely from scratch you can consider to make it as a so-called barebone or white box laptop. Barebones are also featured in a separate section of the overview.

    If just I want to add a couple of numbers together or edit a document, do I need, or should I have to pay for, the ability to simultaneously have an MPEG movie playing in the background?


    I don't know about you but if I want to add numbers together I use a $9 calculator. Granted you cannot edit a document on a calculator but it's quite unlikely you can in 96 bytes of ram.

  4. Didn't expect to see a PICAXE processor by plcurechax · · Score: 2, Interesting

    The PICAXE is in essence a Microchip PIC microcontroller with a custom bootloader to load programs into memory and execute them on reboot/reset.

    I was sort of expecting a general CPU, even if a vintage chip like the ZiLOG Z80, MOS Technologies' 6502, Motorola's 6800 / 6802, or intel's 8088 / 8086 microprocessors.

    It seems more suited to O'Reilly's MAKE magazine and their blog, then on Slashdot.

    A $50 FPGA can be made to work as a 256 color VGA driver (or any size lcd controller you like), and you can easily get it to accept PS/2 input from a keyboard.

    Then you pick your poison for processors, coprocessors, etc - as long as it fits on the FPGA.

    You have lots of options.

    When I were a lad we used to have to build our own laptops.
