I looked at using Debian, Damn Small Linux, Puppy Linux (which immediately panics on boot), and Movix. I decided I might as well stick with Ubuntu so I am building a custom Live CD. I will then transfer it to a Compact Flash card, which will be plugged into an adapter and replace the incredibly noisy stock 4200 rpm hard drive.

Revision as of 05:14, 2 July 2009

WallTop computers... recycle an old laptop by removing all the extraneous parts such as the cdrom drive, floppy drive, (dead) battery and then hanging it on the wall.

I am building one from an old Dell Inspiron 3700.

Operating system

I looked at using Debian, Damn Small Linux, Puppy Linux (which immediately panics on boot), and Movix. I decided I might as well stick with Ubuntu so I am building a custom Live CD. I will then transfer it to a Compact Flash card, which will be plugged into an adapter and replace the incredibly noisy stock 4200 rpm hard drive.

See http://www.debuntu.org/how-to-customize-your-ubuntu-live-cd

Oh! This was a bad idea. Much stuff deleted from this page!

The way to do this is Debian Live!
