My club Tacoma Robotics Society had a booth at Seattle’s Mini MakerFaire a few weeks ago. Since I am the only person who set my electric wheelchair base on fire I had to provide an alternate contribution for the show. Here’s a display I made with a pice of mdf, an Arduino and 97 G35 addressable Christmas lights. – http://www.youtube.com/watch?v=e6X14_BIyWg&feature=channel&list=UL
At the show one of the booths was selling Zipit Z2s with OpenWRT Recovery loaded for $20. I am an embedded Linux junkie so of course I had to find my wife and nag a $20 out of her. Here are a few tips to make things easier for you if you find yourself with one of these. This is specific to the device I bought. It was preflashed with Uboot &OpenWRT Recovery.
Your first order of business is to find a “mini” SD adapter or card. This can be tricky if you’re not an electronics hoarder.
Next step format an SD card to ext2 for your Zipit’s new OS.
Download your new OS. We’ll be using a modified version of Debian Sid called z2sid. Use the one on this page (z2sid_v6_uboot_rc3.tar.bz2). http://mozzwald.com/z2sid
Mount your SD card –
Unzip your OS onto it -
# tar -pxjvf /path/to/z2sid_v6_uboot_rc3.tar.bz2
Unmount and eject your SD card. Plug into the front of your Zipit. Power it on.
TIP – type in ewoc-z2sid.sh to get to the wifi configuration.
TIP – dropbear is a simple ssh server
TIP – “apt-get install nginx” for a web server
TIP – z2sid comes with Python!
