I am vapour, but you may know me as paul, a somewhat frequent contributor to Hackaday, my projects can be found here. I come here because I am beginning work on a minimig based laptop not unlike the one found here by user "MegatronUK".
I am currently at the planning stage of the design and am assessing what criteria this laptop should contain. My current planning is shown below:
**SCREEN: need to determine ideal input method and aspect ratio.
**BATTTERY: need to asses system requirements (current draw)
BOARD: minimig http://amigakit.leamancomputing.com/cat ... rrency=CAD
MOUSE: (synaptics touchpad?) a port for mouse. already have PS/2 mouse, need a touchpad...
KEYBOARD: slim keyboard with a port for an external keyboard. http://www.dealextreme.com/details.dx/sku.1846" onclick="window.open(this.href);return false;
JOYSTICK place minimig to allow access http://amigakit.leamancomputing.com/cat ... cts_id=610
PSU place minimig to allow access bypass the batteries
SOUND: generic junk http://www.dealextreme.com/details.dx/sku.4 / http://www.dealextreme.com/details.dx/sku.2185
- add a switchable buzzer+LED to emulate disk read as per article http://hackaday.com/2010/07/28/emulatin ... ppy-drive/" onclick="window.open(this.href);return false;
At the moment, I am having trouble finding information about the minimig output modes and ideal aspect ratio so that I can choose a screen. It seems that the minimig only outputs via VGA and that the VGA cable can be converted into RGB component cable connections with a little modification of a VGA cable as per this advice:
Is this method correct/advisable? Any thoughts / comments?VGA and Component video are essentially the same thing. If you pull
apart a VGA cable you will see that inside there is a RED, GREEN and a BLUE
whire inside. All VGA is is component with additional wires to control the monitor
from the computer. A VGA to Component adapter can easily be made simply by
splicing pins 1 and 6, 2 and 7 and 3 and 8 while shorting 4 and 5 as vsence (ground).
Each of those pairs in that order are; RED, GREEN and Blue.
