raspberry pi 3 wifi latest raspbain

I have the latest Raspbain, a Raspberry Pi 3 with built-in wifi and the machine is running. BUT how do you configure the wifi? I find no GUI tool for this and when I try the command line process method from this site it does not work because when I issue the command iwlist wlan0 scanning the machine...

lastest raspbain and network configuration

The lastest verison of raspbain has no static ip configuration tools installed on the image. There use to be a network configuration tool installed in the menu that would allow you to configure eth0 as a static interface with the ip address and all the rest that you needed to make a wired connection...

Re: A kickstarter for Raspberry Pi lovers

Part of what I liked about this is that the body is provided along with all the movement parts. Also it appears to be setup for tank battle. Something that my 5 year old nephew and I can do together.

A kickstarter for Raspberry Pi lovers

Here is the link to a project that uses a Raspberry Pi in the most interesting way. Low level tracking as is 4 inches (100 mm) off the ground and you can shoot each other without harm.

Re: using the raspberry pi and the Oculus Rift

Just got update #18 from Oculus confirming that delivery is on schedule starting in the middle of March. They have also developed a Latency tester for movement to display changed complete speed evaluation. It appears that this will be some form of a game changer for the industry.

Re: ROS (Robot Operating System) on RPi

We also have had 1 person build the tree and created a .iso image to be installed on an SD card for use. The link to the .iso file is also in the build instructions at the beginning so that you will no...

Re: ROS (Robot Operating System) on RPi

No problem. No I think that we should just put all the apt-get items grouped together in several steps but make no distinction as to what they are used for. That way we don't have to figure out exactly where each falls in sequence. It appear that we may have more support for ROS on the Raspberry Pi ...

Re: ROS (Robot Operating System) on RPi

Kai - I just figured that loading all of the apt-get items would be the default structure as it is easy to do.
It's the ROS stuff that can get to be a pain sometimes.

In the list of apt-get modules to load is lsb-release which is needed to correctly identify the system as:

Re: ROS on RPi

I am close to getting the ros-comm package built. I am in the finishing stages of building it. Then I will be putting a fresh copy of the os on another SD card and doing one more time to verify it. The next step then is to see if the desktop version will build.

Re: ROS on RPi

Ros already has a build environment on github this will be add code and docs to that environment. What I want to be able to do is add links to our system install environment so that we can load prebuilt software to our raspberries and just run ROS.
