houkimeDo we have a component for IR receiver?00:51
houkimeok, looks like we have00:55
houkimebut there's an strange _not_a_component_ on IR receiver though00:56
houkimeoh, this looks like a wire teleporter thingie00:57
houkimebut one wire is out of place though00:58
houkimebq-gpio just end at the boundary.00:58
houkime*ends00:58
houkimeemmm... ok, i guess i understood.01:01
houkimeseems like sensors page needs rechecking decoupler-wise.02:17
houkimethere are way too many separated powerpins undecoupled in sch.02:18
houkimeCorrection: While they are decoupled on paper, it is often like:02:20
houkimeoften like smb thought it is a good idea to decouple pins in separate parts of IC using only one decoupler for them all.02:22
houkimealthough maybe it can be done in some cases using the other side of the board,02:24
houkimeit doesn't seem like it is always possible/good solution.02:25
houkimeesp when you have 1v8 and 2v7 rails02:28
houkimewhat are the requirements for IR placing&20:36
houkime?20:37
houkimereceiver and transmitter should probably be together.20:37
houkimethey should be on the edge20:37
houkimethey should be on the upper surface of LOWEr so that they are facing spacerframe20:38
houkimeanything else?20:38
atkhoukime: there's a window on the N900 for the IR21:23
atkso it has to line up with the window21:23
atkI can't remember if the window has a divider but that might also matter21:23
Joerg-Neo900there's a whitepaper covering all21:41
Joerg-Neo900ir.pdf iirc21:41
Joerg-Neo900http://neo900.org/stuff/papers/ir.pdf#1521:47
Joerg-Neo900houkime: ^21:52
houkimethx21:53
houkimewhat is rationale behind  having 2 battery fuel gauges btw?22:22
Joerg-Neo900one for legacy, one for best performance22:35
Joerg-Neo900the bq27200 is suboptimal22:36
Joerg-Neo900but needed for 100& maemo compatibility22:36
Joerg-Neo900100% even22:36
Joerg-Neo900BME is one of the closed parts that are not exactly easy to replace22:37
sixwheeledbeast^did bme-replacement become usable?22:56
Joerg-Neo900well, sort of23:15
