Stuff has bugs, both hardware and software. One of the hardware bugs in Openmoko phones has been bug number #1024 causing things to happen that prevent the GSM chip to go to ‘deep sleep’ mode to save power.

Someone came up with a fix: add a capacitor.

So we did.

The suspend power consumption dropped to around 6000 µA from around 15-20000µA when I now allow the GSM modem (Calypso) to go to deep_sleep mode. The 1200mAh battery should now give up to 200 hours = 8 days of power. Of course this is theoretical – I also need to use the phone to make calls, let GPS show me my location etc etc – and as I move, the GSM needs to wake up ever now and then because of the changing base stations. So nowadays I recharge it every other night still being able to make calls and do other stuff with it. Nice improvement!

I started today two new IRC channels on Freenode to discuss the usage and development of two great Free & Open source programs, Tangogps and Smile, and also to allow free & realtime discussion of the user communities.

Tangogps is a map & gps program for Linux. Tangogps is written by Marcus Bauer and ir runs on devices like Openmoko Freerunner, but also on desktop computers. The channel I started is #tangogps, feel free to join! (Ajax client and Java client)

Smile is a slideshow application for Linux by Stéphane Gibault, see my blog post on Smile. The Irc channel is #smile-slideshow. Join the discussion there! (Ajax client and Java client)

Let the discussion flow!

What’s your experience on these apps? Using Tangogps or Smile? Best things about them?

About IRC – I think the IRC commands are a bit of a pain.. on #tangogps, I first dropped my op rights only to realize that after that I wasnt’ able to register the channel.. So 4 of us had to leave the channel to gain admin rights again.. But I’m learning :)

Openmoko Inc, the company behind the Openmoko Freerunner Linux phones released their new product, Wikireader. It’s a small device to read Wikipedia offline. The files are stored on uSD card, also the small Linux kernel is supposedly loaded from the card so this should be a nice hackable device.

It is still unknown if there will be a developer/user community around Wikireader and what will Openmoko do this time better than with Freerunner. You can try to find some answers on the Openmoko community mailing list

Some ideas have been bothering be for a while, decided to write them down here, maybe they’re interesting to someone else too.

Nokia 900

  • A great device hardware-wise. Nice to see it running Linux but phone stack still closed. See ‘This is Linux from Finland
  • I wouldn’t be surprised it it was already patented, but I think it’s a great idea to zoom in/out by making a circular motion on the touch screen – maybe something Openmoko browsers could use?
  • When you turn N900 screen to portrait position it’ll start the ’simple’ phone app – and on landscape it runs the ‘computer’ stuff. A nice idea again!

Paroli

  • Work to make it work smoothly on SHR is being done (GREAT job Laszlo!!!), see http://git.paroli-project.org/
  • Some UI hacks might be also there soon. I myself prefer having the buttons on bottom of the screen to be always able to see what’s on the screen.
  • Waiting to see a working package on SHR to allow easy installation: opkg install paroli

SHR

  • Settings is nice, supports stuff from power management to connections to much more, also looks good.
  • Phone apps work OK though slow when reading stuff from SIM (-> opimd support, where are you…?)
  • I like the buttons at the bottom of the screen – but they could use some rethinking:
    • Most of the time the ‘next’ button (be it new, OK, send) is on the bottom left.
    • Sometimes there’s a close/exit/back button on bottom right, sometimes not. This makes you have to close an app (for example call log) from illume top bar. Not very nice.
    • Now there are 1-4 buttons next to each other (settings: only the quit button, phone log: call/add/numbers/duration)
    • I like the ‘options’ -button of contacts to show more stuff. How about moving ‘new’ there and adding ‘close/back/exit’ on the bottom right?
  • A single button to take you to ‘home view’ would be nice – that’s why iPhone has that one HW button.
  • Hundreds of contacts in the contacts list makes it a pain to scroll. Some thoughts:
    • The finger scrolling works nice
    • The scrollbar’s too small to use
    • How about starting the view from middle of the list, not from the beginning (to reduce need of scrolling)
    • How about creating jump buttons:
      • Alphabetic, like Paroli does
      • or start/middle/end
  • So far SHR’s been the most usable distro I’ve had. People are not complaining about the audio quality, suspend/resume is reliable, nice GUI’s to start GPRS & GPS etc.
  • I’d like to be able to adjust the volume during call
  • I’d like to see the duration of the call during a call (can I already see it? Don’t know.. :)

Misc

(also have a look at my outdated Openmoko wishlist)

The Openmoko (being a free/open phone) community has released community updates again. To see what’s happened during the last two weeks, check http://wiki.openmoko.org/wiki/Community_Updates/2009-09-02

To me personally the biggest thing is that Paroli (the telephony app) is being worked on to run on SHR (one of the distros)
