Re: Removed Raspi-Config... how??

is luajit also a dependency? Just want to make sure I take it off my 'remove' list if it is. Easiest way to tell is to install raspi-config and see if it pulls in luajit as well. Or you could ask it to remove luajit and see if it will say it will also remove raspi-config. You can always answer "N" ...

Re: GPIO Pins and P5 Socket.

DNC connections have always been connected to 3.3V or GND, but initially the design wasn't finalised. Now it is and those pins are confirmed as being 3.3V or GND according to the latest diagram. They are safe to use. Soldering anything directly on to the Pi will (probably, please correct me if I'm w...

Re: Removed Raspi-Config... how??

raspi-config depends on lua5.1, so by removing this you have removed raspi-config as well.

Easiest thing to do is just install raspi-config again and all the depends should be pulled in with it

Code: Select all

sudo apt-get install raspi-config

Re: How to check memory and cpu after raspi-config overclock

The CPU will drop back to 700MHz when it is not very busy. What you need to do is have a CPU intensive task running in one terminal session, while checking the cpuinfo_cur_freq value in another. You should see it ramp up as CPU usage approaches 100%, then drop back down when it is idle. The gpu_mem=...

This is something that happens sometimes.

You should also look very carefully at the...

Re: Connecting a relay

Another thing that strikes me is the fact the specs say "working current 105mA". Presumably this means the relay will take 105mA at 9v when active. I doubt the usual little 9v batteries will be able to supply that much current for very long. Perhaps the relay board is meant to be driven by a 9v PSU?

Re: Connecting a relay

As you have guessed, it looks like you don't have a return wire connected to the Pi. You can't have a circuit with only one wire - the current has nowhere to go! I think the solution would be to connect the GND pin to one of the Raspi's GND pins as well as the battery. Test this first by putting som...

Re: Problem ssh'ing to PI directly connected to ubuntu lapto

From that log I can see that Ubuntu is definitely using Dnsmasq to handle the local DNS and DHCP. The next step is to see what IP address it has assigned to your Pi. The easiest way to do this is to connect a screen and keyboard to the Pi and run /sbin/ifconfig eth0 on it. This will show the address...

Re: SD card from Raspberry Pi 512Mb to Raspi 256Mb

Yes.

I often switch cards between my 256MB Model B rev.1, 256MB Model A and 512MB Model B rev.2.1.

The main thing you might need to look out for (assuming your friend has a Rev.1 model B and you have a Rev.2 Model B) is that some of the GPIO pins changed between revisions.

Re: Problem ssh'ing to PI directly connected to ubuntu lapto

As a guess, I would assume that your Pi is given an address of 10.42.0.2 as the next one up from the laptop's 10.42.0.1. Try ping -c 4 10.42.0.2 and if that works, ssh pi@10.42.0.2 There is possibly a log file for the Ubuntu Connection Sharing that will show IP addresses being allocated, which would...
