AudioTOH
 

'Kitchensink-ish' TOH with all components remotely related to audio.

You name it, it will be there:
- i2c level converter
- i2c spi bridge
- micro-sd card
- full sized sd card
- sd mp3 decoder
- digital volume controller
- separate amps for L & R
- FM receiver
- headphone jack / line in
- micro usb port

Still to add:
- FM transmitter
- bigass speakers
- battery
- charging circuits (in/out phone & separately)
- physical control buttons
- full sized usb slot
- usb host (just for reading mp3s)
- lightning connector


This one will be the most complex TOH ever. I have my doubts it will ever see the light or be remotely affordable. But I learn a lot.

WOOOW WTF? :eek::)

Re: AudioTOH
 

Even if you only put a few of these things in the final version, I want one!

Imagine throwing a HWKB into the mix - you would be very close to the N900 then.

Re: AudioTOH
 

So not so much a TOH rather a whole seperate device that just happens to attach to your phone

Re: AudioTOH
 

Basically yes, a whole shebang of devices that share the Jolla device as a display and configrator unit. Nice :D

Re: AudioTOH
 

that is a more accurate description.

All this goodness and not a single funky LED? I'm disappointed :p

to decrease the chance this will ever see the light, I downloaded the SDK and will do all programming myself. will be for sale around 2017.

Ordered all possible candidates that have acceptable thickness (<10mm) and enough but not too much power.

Will mount to BreadboardTOH to see if it can top this video.
