Re: Advice on Arduino integration and Weather Grabbing

I believe that is correct from my reading - AS LONG AS the Pi is the master - but i have read if there are multiple other devices on the bus at 5v then it is a safer idea to have a level shifter. The whole module only costs $3-$4 on EBAY so it is a good insurance option.

Re: Advice on Arduino integration and Weather Grabbing

Yep already go the level shifting happening - not a problem thanks.

I already have i2c in place so no dramas there - easier than parsing text streams etc.

Advice on Arduino integration and Weather Grabbing

Guys, I have an Arduino that is running my home heating system (i am just in transition to this from a Picaxe based system). I intend to integrate my Rpi and the Arduino through i2c. I intend to continue to use the Arduino to provide the heavy lifting and managing of sensors, relays and the like. I ...

Re: Is my brand new Pi DOA ?

I have tried the alternate bootloader that is listed on the troubleshooting FAQ and that has made no difference

I will connect a SD card reader to one of my Linux boxes and write the image from there as the next step

Re: Is my brand new Pi DOA ?

I do computers for a living so am pretty sure i am OK on the flashing side. I am using the download from the downloads page on here. I have burnt it on two different windows machines with two different SD card readers. Yes when i view the files on the SD card i can see about a dozen or so in there. ...

Re: Is my brand new Pi DOA ?

thanks for taking the time to respond -- yes i can confirm i am using the hardfloat from the download link on this site - downloaded as of 15th May. I have started going through the troubleshooting section. I have tried another 5v adapter with another micro USB cable and the same symptoms - so that ...

Re: Feasbility of an in-car media server

You can then use the Pi as the client to the MediaServer running on the Router - so you could have a nice interface like the squeezebox interface running on the Pi talking to the Logitech Media Server running on the Router - obviously you could run any client/server combo you like - this is just the...

Re: Cut the power cord!

Make your own power pack is easy enough - look for quality batteries - NIMH is the easiest to work with - you will get Tenergy D-Cells up to 10,000mah for around $20 each in the US - four of these will give you a steady 4.8v and will last something like 15 hours (at full load of 700ma for the Pi) Or...

Re: Feasbility of an in-car media server

I guess you could do this - but you are going to be sharing the USB bus with both a wireless dongle and an external hard drive (unless you plan on using the SD card for media ?) I think a better bet would be one of the routers that runs OpenWRT - plenty of options there that you could power from 12v...
