Re: Rpi and reley to switch on/off lights

I know there are plenty of tutorials out there but my problem is I know about nothing of electronic, my bad. I wanted to buy a relay like this : http://i.ebayimg.com/t/MODUDO-RE...

wifi hotspot question (I think)

I have a number of Raspberry PIs which I set up to connect via wifi to my router by editing the /etc/network/interfaces file and adding the password for my router. What I wanted was a way of connecting to the Pi without having to configure it with the pwssword for my router. ie make the pi act as a ...

current clamp meters

Hi There was some discussion some time ago about reading domestic electricity meters with a Pi and the best solution seemed to be counting the LED flashes using a photoresistor. In the case of older meters, it seems we need to use a current clamp http://www.powermeterstore.com/p8578/efergy_xl.php wh...

wireless relays

I have a pi operating certain relays in my house (lights etc). Is there a generic solution for this to be wireless? It would be pretty useful to have a relay I can turn on or off wirelessley via a usb dongle or rf transmitter coming from the gpio pins There was an article about turning on and off so...

RPi poweroff issues

I have a raspberry PI in the car and the power goes off when the ignition goes off which means it doesn't shutdown nicely. I'm not sure if this has caused a problem because there have been alot of other intermittency issues, but I imagine it would be better to shutdown nicely. I was wondering about ...

Re: usb stick problem

I've got a usb stick which I've used before but I reformatted it on ubuntu using the 'compatible with all systems (FAT)' option. I then put it into the usb hub connected to the PI and do the following... mkdir /media/usbstick mount -t vfat -o rw /dev/sda1 /media/usbstick cp somefiles /media/usbstic...

Re: usb stick problem

just rmdir /media/usbstick if you did anything wrong, it will refuse to do bad stuff, and just give an error as for formatting, get a root shell (sudo -i) then type in mkfs. and hit tab twice you should get a list of options similar to this: mkfs mkfs.bfs mkfs.cramfs mkfs.ext2 mkfs.ext3 mkfs.ext4 m...

Re: usb stick problem

You need to say what tool(s) you used to reformat the stick. Sometimes reformatting does not work unless you wipe out everything in the partition or on the device with something like "wipe". Also, after creating a new file system, it is always wise to run fsck to make sure the file system is clean ...

Re: bluetooth dongle (again)

There is a serious bug with the current version of Raspbian and Bluetooth. If you boot the Pi from cold with the dongle attached it doesn't get initialised, however it does when you insert it into the USB ports after boot up. There is obviously a script missing some calling, I don’t know where but ...

Re: bluetooth dongle (again)

I know it sounds like a very simple answer, which anyone could give, but if you see it using lsusb, and yet it still does not work, could it be that you're just not getting enough power to it? I have similar problems with a wifi dongel which always shows p in lsusb, but doesn't always light up and ...
