Apple announced their tablet device, iPad two days ago. Immediately it became very popular around the internet, as expected for an Apple device. Here’s the cream.

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.

Thanks Antti & open hardware!

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!

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
- We’re still waiting to be able to use the accelerometers to silent the phone / answer a call / something. Saw today Mickey started to write accelerometer support for FSO – very nice!
(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)

This here is the new Nokia N900 phone, running Maemo5, a Linux distribution. Wow!

(the downside is the ~high price and there’re chances that some bits of it are still closed)
