stand alone GPS/Accelerometer?

While surfing I found this unit. I do not know cost, but it seems to contain a lot of the features in one small package:

    Wow nice find. The second device, KinetaMap looks exactly like the one sold by MaxQData for rip off price of $499. They've probably just have modified firmware to output 20 Hz. I could possibly support the accelerometers on that device, for $199 this device might be probably worth testing. It has only 1 Hz GPS, but the accelerometers might be very good. I'm thinking if I should buy one?

    While the first device says all the right keywords to make my mouth foam, I'm guessing it to be hugely expensive. Got price info? It's probably something that could be used to guide missiles or fly UAS :) Also good for RaceChrono if some extra money :)

    Just been reading the user manual for KinetaMap. Turns out you can easily turn the accelerometer logging to 20 Hz.

    The device does not send real time accelerations over the Bluetooth, so with the standard firmware the accelerometer data would be available only when downloading the logs afterwards (can be done via Bluetooth directly to the phone). The firmware can be modified by anyone, so this could be changed ...

    But never the less the logging feature on the thing is great too. So if live display is not needed, then just leave the phone at pits, and download the data with phone when back at pits!
  • I wonder if they have a 5hz model?
  • The GPS unit is changable, so you could insert a 5Hz GPS if you so wished. You'd need to modify the firmware to ensure the serial port was correctly configured but there's people who've done that before on the forum.
  • Which forum? Sparkfun?

    Sorry, yes. The Sparkfun forum. The link I emailed you yesterday.
  • Ah yes, thanks. Good to have it here too :)
