Re: Is the raspberry pi 2 a drop in replacement?

I didn't see anybody mention it, but the new 2B (as the B+) is using microSD, not SD cards. If you have a µSd card + adapter in your old B, then it's no problem after the updates. Maybe that was clear to you, I just wanted to make sure :lol: Yes I was aware. I wasn't going to hammer a full blown sd...

Is recently killed a USB stick by using my rpi as a webserver/mysql db/mediaplayer/etc for about 1 year... http://www.raspberrypi.org/forums/viewtopic.php?f=66&t=91277 This is probably due to the limited write cycles on the USB stick.

So it seems I managed to kill a kingston dt rubber 3.0 16gb in about 1 year.

Re: IR remote

Short answer yes, it should work, certainly with a gpio ir receiver. Search on google for a guide on how to set it up. You might want to search for a lircd.conf file for your remotes. That saves you the trouble of doing the mapping manually.

Re: USB ports

all depends from the power supply you use to power the rPi and what wifi/keyboard/mouse you use. If the power supply isn't stable/strong enough it will never work. If your wifi adapter/mouse keyboard are low power you might get away with using an unpowered hub. My rpi had no problems powering an usb...

Re: Raspberry v1. Share ground from 5v and 3v pins

I think you miss a basic principle in circuits. In a circuit all groundpoints are connected together. This is necessairy because it is the reference point for all the other voltages in the circuit. If a point has a certain voltage you always measure this against a ground point. example: a circuit wi...

Re: The one feature needed for future RasPii

My understanding is that the early prototypes had switching regulators, but they were sacrificed and switched to linear regulators in order to get the bill of materials & build into the target price point.

Re: The one feature needed for future RasPii

maybe not a feature but rather a suggestion: replace the linear voltage regulator with a proper switching regulator. The raspberry pi accepts 4.75V - 5.25V as power supply. Since it uses 3.3V internally the linear regulator disspates 1.45 - 1.95V. This means about 30% less power consumption to feed ...

Re: Will an external sound card be in sync with video?

Too bad HDMI audio extractors are more expensive then the R pi itself... And it needs it's own power supply...

That way we losse the idea of a cheap, low power media center...
