Experiments with the Linksys NSLU2 - the Slug
http://johnarthur.wordpress.com/2008/03/25/a-high-resolution-ip-webcam/
introduced me to the Slug - it explains how to add a HD webcam and provides a ready made firmware
the picture quality is fantastic - and you can run 2 cameras at once.
There is lots of documentation on the Slug here
I managed to build a working OpenWRT Kamikaze tool-chain and can compile c-code
- so I decided I would try to make it control external circuits, run an HD camera and a USB2 external disk on Samba and FTP
There are only a few GPIO ports but there is a working i2c line used for a real time clock chip on the PCB
i2c notes - (developed with the Slug but also of use to the Sweex/Edimax routers) i2c drivers for common chips that compile for Debian or OpenWrt NSLU2 (Slug) driving a PIC microprocessor as an i2c slave to control 2 model servos Remote PIC as i2c slave as general purpose measurement device PIC as i2c slave with Graphic Display PIC as i2c slave with Graphic Display - drawing primitive elements (lines, circles etc) on command |
Playing MP3 and WAV sound files on Debian Slug
Clone a Debian Slug - copy Slug firmware and USB disk contents to a new system
OpenWrt (mainly) Notes - make a Slug boot up on it's own if the power goes off then on again
OpenWrt Slug as a USB gadget - mimic a USM memory stick - not yet working
OpenWrt Kamikaze on a Slug - boot from USB stick - avoid having to have a USB disk spinning all the time for simple control uses
Debian Notes- hardware add-ons - Use a USB Flash drive with a swap partition (but set minimal use of swap - and reduce memory use)
add a UVC Webcam - add Motion - add a WIFI dongle - add a USB/rs232 adapter
Debian Notes - cgi PHP etc - Where to put files to make a web server with external device control scripts
Adding a digital picture frame - Brute force method!
Openwrt with HD webcam - update 2011 - Python for cgi scripting - all in the internal flash
Debian Slug with Easycap USB to video converter
OpenWrt Slug with Easycap USB to video converter - ALSO cheap camera for mjpg_streamer
OpenWrt Slug Backfire toolchain - used to compile helloworld, Blassic and usbscale
