Ordered from DX.com it claims to supply up to 10A at 5V from a 12V source.

I’m looking forward to seeing if that is indeed the case :o)

As I ordered more than one, they’re going to be used for both the Joggler and Portable Hotspot projects.

Nohands is a dbus-based hands hands-free profile daemon. It can be found at nohands.sf.net. The svn code requires a fair amount of work to compile properly, so I fetched the source and debianisation patches from here.

To get my iPhone to work (my android phone worked first time) as apparently it attempts to request the hands free profile immediately. I had to create this configuration:

Apparently some motherboards appear to have mic pins…

I thought this might be a different revision of the board, but it is probably a picture taken from the underside:

The Joggler has a terrible heat sink. It is plastic; no, I’m not kidding you. There is a metal stand at the back that the thermal transfer pad connects to, but even that is too little, too late. It’s enough for the openpeak main uses running a cut-down linux and flash UI, but hardly enough to run a full ubuntu stack on. Thermal throttling isn’t fun, so steps have to be taken to mitigate that.

My car apparently has an OBD II Diagnostic bus

So it should be fairly easy to pull out some data? Famous last words :-)

I’m considering grabbing one of these devices for the audio amplifier.

It’s easily found on EBay, Amazon, and google searches as:

“TDA7850 50W 4 CH 12V Car Audio Amplifier Board DIY Kit”

However, it’s a fixed gain amp, so on the plus side everything is controlled by the computer.

The downside is that every bit of noise will be amplified too.

The joggler (aka O2 Joggler) wiki can be found here.

Currently running an Ubuntu image by exobuzz which can be found here. [maverick 1.9]

Alas, this project has fallen off the world since I have changed cars and invested in an iPad Mini. So far it seems to have most features… pictures when I can get around to it.
