I have a couple of Raspberry Pi projects in the works, but I thought it would be good to share a video I updated over the winter.
I thought it might be helpful to some to document how I go about taking the latest version of Raspbian (available at https://www.raspberrypi.org/downloads/raspbian/) and customize it for myself. This makes it easier for me to start a project and make sure all the Pi’s I work on have the same basic setup.
I tend to work from headless systems, so the first thing I do to the raw image file on my SD card is add a blank file named “ssh” to enable that functionality. Next, add a file named “wpa_supplicant.conf” to your boot directory as well. Include your WiFi information so you don’t have to connect to Ethernet if you choose not to.
Take that disk image you have on your SD card and connect it to the Pi. Connect however you choose (I use PuTTY) and login if needed.
Enter “sudo raspi-config” and make the following changes:
- Change your password (seriously!)
- Change your host name (I use a convention like PiBWIJune18) so I can find it in my DHCP list if I need to discover the IP and so I know which version I am using.
- Expand yout file system to use the whole disk
- set your keyboard type
- set your time zone
- optionally decide if you want to boot to desktop or command line
- optionally enable VNC (though if you are just doing command line, there is no need to do this.)
After you exit and save all that, now is a good time to reboot.
Starting up again, I remove Wolfram Alpha. It takes up about 700 MB and it’s not something I use regularly. I can always add it back if I need it for a project, but I haven’t yet. That command is “sudo apt-get purge wolfram-engine”
Another reason to remove Wolfram is that it seems to have a ton of updates and takes forever. Once it is gone, run your system updates with “sudo apt-get update”.
I run a home NTP server and quite a few of my projects are time related, so I always add NTP. A great tutorial to do that is at: http://raspberrypi.tomasgreno.cz/ntp-client-and-server.html
Finally, I want an easy way to move files between Pi and my desktop as needed. So I set up SAMBA sharing. The tutorial I use it at: http://raspberrywebserver.com/serveradmin/share-your-raspberry-pis-files-and-folders-across-a-network.html
When that’s done, I shut down the pi and make a backup. That’s the file I use to start my next project with, my “Base Working Image.”
Hope this helps. If not, at least I can find my notes next time there is a new Raspian release!
All the clips in one location:
I really enjoyed going to a night launch on the Space Coast on Feb. 9. United Launch Alliance shot a Solar Orbiter for ESA that will map close to the solar poles for the first time. Cool science is coming!
I used this an an experiment to photograph a bunch of different ways. 4 cameras ended up in this final video. My Sony A58 shot the launch in HD, I used my Panasonic Lumix to shoot the rocket gliding under the moon, I used a small “Action Cam” to get a time lapse of the launch, and finally my iPhone shot the selfie videos.
One shot that didn’t make it was a 4K Vertical Launch shot. I started the camera with about 2 minutes to go, but when I adjusted its placement I bumped it. No recording. Good thing I had some redundancy!
From the Radio Side, I listened to the launch on the K4GCC 146.94 repeater, who simulcast the launch audio for every launch via a phone patch. (Well it was a phone patch the two times I heard it). I also attempted to listen to the CCAFS traffic via a scanner. I was able to hear some KSC gate discussions, but no operational audio related to the launch. Something to try for next time!
I’ve been enjoying getting back into Parks on the Air over the last few months. I have about 25 confirmed chases and 2 activations. I shot a video of my Banks Lake activation, where I made about 30 contacts on Christmas Day. Enjoy.
