microNAS
teensy server for use in the field with PDAs | |
Besides one obscure CF+ USB host controller that's expensive & poorly supported, there seems no way to use PDAs with portable USB & 1394 hard drives.
Rather than an iPod, I'm willing to carry the extra weight of a Zaurus + FireLight + battery pack, but there's no way to hook 'em up.
One box
would be self contained w/hard drive, rechargable Li-Ion and ethernet on board.
Another box would just sit between the PDA & a separate portable hard drive- ethernet on one side, USB host on the other. Instead of build-in ethernet, could even have a CF+ slot for ethernet or wireless card.
CPU in server can be wimpy ($cheap) if DMA controller well designed. Only powerful CPU is in PDA to run UI & mp3 CODEC.

Er, carry a laptop to act as a hub? |
|

Laptop (even subnotebook) is too big. I want something twice the size of a 2.5" laptop drive (largest other component is battery). Actually, this is still too big (I want an iPod), but there's too much of a premium on price & small GB in PC Card drives. |

Also, some laptop ethernet adapters are too low-power to support a crossover cable-- they *require* a hub. This device would be designed for 1-to-1 "nets." |

the ethernet jack in the apple powerbook g4 not only has enough power for a crossover, it is autosensing so that you don't need a crossover cable; if it's plugged into another computer without a hub, it does the crossover itself. |
