Do take notice of the hours of DIRECT sunlight needed to charge devices. With less direct sunlight you need even more hours!!! This comes from their own site: NOTE: For maximum power output, angle the panels towards the sun. When the panels are in direct sunlight but not angled towards the sun the power declines about 20%. When they are angled away from the sun the power drops off 80-90%. Dirt and scratches on the face of the solar panels will reduce the amount of light hitting the solar cells and reduce the power generated. To clean them use a damp non-abrasive cloth. In other words, when walking around, you would normally only reach 20% of the power, unless you can always walk with your back to the sun? ;-) BTW any further offtopic discussions should probably not go the mailing list ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Perfect set of Neo companion (and power questions).
1) A powered 4 port hub that accept 5-6V external power (hacked to power a usb host connection). The perfect charger for the neo.. and, well, a hub as extra function. 2) A 2.2A 5V power supply (4x500 mA = 2A + overhead). 3) A led flashlight powered by 4 D-cell (LR20) batteries that also can power the hub. (possibly also usable with 5 D-cell for rechargeable batteries (NiCd/NiMH) at 1.2V each). 4) usb keyboard and any other gadget... 5) An extra set of batteries :-) according to wikipedia, alkaline D-cell have a capacity of ~20 000 mAh... At 6V given 4 D-cell but I guess no more will come out of the hub at 5V. That's 16.7 times 1200 mAh... but how efficient is the charging of the phone... can one expect 1 or 5 or 10 full charges? And how much dose the phone consume over usb when already charged? Would be nice to be able to get a rough estimate on have long lifetime one can expect. /LaH ___ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
