OggVOSH: The (soon-to-be) Open-Source Ogg Vorbis Player Answered
I've been eying the VS1000, a little bitty chip that is basically an all-in-one Ogg Vorbis player, just add a crystal & memory. Its so beutiful, so tiny yet so complex... it even has a great default firmware.
I've finnally got around to making this. I'm sending the PCB off to be made, and getting parts to prototype.
Size: 2.19"x1.48", roughly twice the size of a new shuffle, or half the size of a new nano. I haven't figured out depth, but it uses li-on batteries, so it will not have a lump on the back, it should be comparably thin.
Capacity: uses microSD cards
Connections: 3.5mm stereo headphone jack, microSD card, and miniUSB. Via miniUSB, you can charge the battery, as well as read/write to the SD card.
Audio Support: Only Ogg Vorbis, but then again, it is the best codec, you can convert everything to it ;-) Max bit rate: 500 (beat that Apple!)
No screen :-(
This is tricky. For me, if I didn't buy any spare parts, its going to cost me $100. If I had an SD card, it'd only be $80. If I semi-mass produce them (more than 20), I know I can cut at least $10 off that price.
So, it pretty much beats the Daisy, our, the OS/DIY community's, current audio device all around. Except one thing... it isn't a beginners project, involving nearly all SMD components, the only exception being the headphone jack. And the main chip is a bit of a pain to solder -- 12 pins on each 1 cm side ;-)
Still, I think this is promising... along with my micro-POV... in making things smaller, like the "real" devices :P
