Eye-fi: handy for the lazy geek
I can’t count how many times I’ve forgotten to download pictures at home, then wanted to access the data that was firmly locked away on my camera at home on the following days. Enter the Eye-Fi: a SD memory card that contains a wireless chip-set and an on-board client that uploads your photos as you go along. Since my wireless network is segmented from my home wired network, the built-in client doesn’t work from my powermac – but there is a nifty python script that’ll act as a server for the card, so I’ll probably stick the script inside a chrooted environment on my home server and attach that to a dedicated network interface on a private vlan to a dedicated wireless network. (My home wireless setup involves some previous generation enterprise class gear, so I can run all the ssid’s I want with private, tagged vlans at will.)
The card itself is an interesting piece of hardware. There’s a tear down here. The RF chip might be an interesting piece to build for an Arduino module…
