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!

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

proto.youloc.net

proto.youloc.net

Short in English: see www.youloc.net!

Jotta kiinnostuisit hommasta, vilkaise ensin sivua proto.youloc.net. Klikkaa kartalla näkyvää vihreää pistettä niin näet nimen, nopeuden ja koordinaatit. Jep, se on joku nykyisistä youloc.net -prototyypin käyttäjistä tai simuloitu liikkuja. Klikkaamalla ‘zoom in and follow’ näet tarkemmin missä kyseinen täppä menee. Kokeile myös seuraavia:

  • klikkaa kartan oikean reunan + -nappulaa, valitse sieltä ‘user tracking’. Nyt näet myös liikkujan historiaa.
  • paina yläreunasta ‘USERS’ nähdäksesi muiden (ei-liikkeellä olevien) käyttäjien tietoja.

Noniin, nyt kun kiinnostus on herätetty konkreettisella esimerkillä päästään asiaan.
