I found today, at Fry's Electronics, a 2.2" Sony TV tuner for $99. The neat thing is that it uses 3xAA batteries and has a band to strap it to your arm (which double-duties as the antenna). Since my Espresso does SVideo out from the i810 (nice OpenGL BTW), I will pass it through my Entech bi-directional Composite-SVideo converter (which also sharpens picture/stablizes video jitter) then onto my Nippon America A/V UHF transmitter onto channel 15 (you got to love HAM radio fest -- only $20). At that point, the 2.2" TV Tuner would be tuned to channel 15 and should pick up audio/video from the wearable.. without direct connections to the wearable. In addition, anyone tuned to channel 15 within a ~100 foot radius could pick it up too! Well, that could be good and bad.. anyone attempt this idea before? I know 2.2" is a bit small for 640x480, but it would work never-the-less. I'ved used the Nippon America UHF transmitter for years and it has wonderful clarity.. no static or video artifacts. > Michael Paine wrote: > > > What does it take to make something like the Liteye?

I wish the Liteye VGA mono was cheap. It's not :( > > -- Doug -- Subscription/unsubscription/info requests: send e-mail with subject of "subscribe", "unsubscribe", or "info" toWear-Hard Mailing List Archive (searchable): http://wearables.blu.org please, Please, *PLEASE* don't subscribe through a forward/false domain
