Gsm And Screen Hack Options

[guylhem]

Hello

Now that albertr has succesfully added bluetooth and wifi, the challenge seems to be adding GSM, upgrading RAM and replacing the 3.7" screen by the SL6000 4" screen perfectly readable outdoor.

I have finally purchased an old clamshell for the screen hack purpose (I'm waiting for the delivery!) and I will be happy to fully document the process, like I did for the Simpad MMC and bluetooth addon. If it works, it shouldn't be different on the C3xxx.

Upgrading RAM has already been done before - the rick is finding the RAM chips. So far I had no success trying to purchase some for the SL6000. I think I'll need some help there.

The big work will be on the GSM addon. I have both a CF GSM (which could replace the microdrive) and a GSM module (which may fit inside), and I need to work on the antenna and sound issues.

Basically, there must be an antenna somewhere, and the sound must come from somewhere. The best idea I have for sound output is to use SCO (users would need a bluetooth headset) since the clamshells, unlike the SL6000, have no microphone. The other alternative is to drill a hole to plug a headset, a bad idea IMHO. Using SCO will require a MCI codec.

Can I post my GSM/codec/BT datagram try here to have some feedback?

The real challenge for all these hacks are 1) stable drivers and 2) reproductibility IMHO.

For the first point, I will include drivers in the next version of the guylhem-rom, which will no longer be SL-6000 specific. Hopefully they will be worked on, after the initial proof of concept, by daily user who will notice bugs if any.

For the second point, I think we need a commercial partner. It it not cost-effective for me to do that, but I know some local business would could certainly provide such services. Please see the other post.

the two topics make this hard but there is to much info that needs to be exchanged in my opinion,

as i indicated in the other topic a am intrested in how you want to wire this up, the cxx00 series do have a microphone input and can use a 4 ring headphone jack, i dont know if you can do microphone input and stereo output (ideal solution)
