You'd think with these fancy 0.18 micron processes, and OLED displays, soon there will be portables on the market that work for a month continuously on= one battery. Anyway, I've got my fingers crossed. Do you like the prism? Can you use it with the minijam reliably? I imagine you recharge it every night, right? That way as long as you don't play mus= ic for more than ~2 hours per day, it will never run dead. With the Visor Deluxe, changing the batteries every day isn't really practi= cal (I even have NiMH rechargables). There's a small but finite probability th= at when you remove and replace the batteries, you don't do it fast enough, or = the contacts aren't made just right, and it will lose all its memory contents. Which sucks. If I use it every day, I have to reinstall everything on it about twice a month. > On my own time, in the next week or two I will look into your software and > talk with the boys at Innogear to find out their stand on Linux with their > product and I will see what I will come up with.=20 Don't bother. I had lengthy communications with them, and while they were initially open to the idea, they wanted me to sign an NDA and agree not to distribute the source. So instead I reverse engineered it, only to find an ABSOLUTELY BRAIN-DEAD filesystem on the mmc. A monkey could have done bett= er. These digital cameras use a DOS FAT filesystem on the mmc. That would have been 1000 times smarter, and would have made it a lot easier for 3rd partie= s to write software. With my digital camera I just pop it in, 'mount' it like a filesystem and use unix 'cp' to get files off it. It's beautiful. The format of the MMC is laid out in the 3 structs in mjmmc.h. Most of the data fields have been discovered. Ideally though, a GUI would just call the mjmmc program, rather than subsuming its code. If you want to transfer songs over the USB cradle, you'll have to ask Arnim, since he reverse-engineered the communications protocol it uses.

(I can check my email from work though) Please join the mj-tools-devel mailing list (from the sourceforge project page), and we can communicate through that. (and in addition, Arnim and an= yone else interested can see your ideas) Cheers, -- Bob Bob McElrath (rsm...@st...)=20 Univ. of Wisconsin at Madison, Department of Physics |
