Only one accelerometer
RuiSeabra: Do not remove one of the accelerators, having two vectors is useful for many applications.
daveb: I've heard lots of contradictory information about this, but I'm certainly not an accelerometer expert. My understanding is that as accelerometers detect lateral movement, but not rotation through their axis, the second accelerometer is intended to detect movement in one accelerometer when the device is rotated through the axis of the other. However, if the devices are too close together, it's difficult to get a useful reading? At the moment, are there freerunner applications which require two accelerometers? (does omnewrotate use both?) My understanding from the lists is that connecting both interrupts to one accelerometer will offer more benefits than sticking with two accelerometers.
No change to case design
daveb: For gta02-core, we're planning to build something that will fit inside the GTA02 case. A new Id involves lots of complexity and cost - designing the case, manufacturing molds, properly understanding the EMI properties of the new case, and designing the aerials that need to fit in it. [Though as Werner clarified, this wasn't intended to discourage folk that want to investigate a new case. New case designs would be fantastic, but aren't part of what we intend to deliver through gta02-core. We will be working to a board which fits the existing gta02 case - or any alternative case which works for gta02 boards.]
What about USB 2.0?
Pini: The title says it all :) It would be for sure a great improvement. Thanks.
Werner: I wish :-) Unfortunately, the S3C2442 can only do USB 1.1.
Proper buzz fix
Mazikeen: Will there be a mod to prevent the ingress of GSM signal via the headset mic input, or indeed any other way t might find its way inside the can?
Werner: proper application of beads is indeed very high on my list. I'm also rather suspicious about TX/RX passing unbeaded between CPU and GPS. This will require the addition of components that don't exist on the original BOM, so we'll have to be careful what this does to the general budget. But I think it won't be a problem to get this right.
Mazikeen: Can we finally sort the low dc blocking cap value and parallel resistor value Joerg identified before release?
