Got a chance to hang out with the excellent Dave Jones on Saturday night at his studio. He’s been working with video artists since the 70’s, designing and fabricating electronics for live video signal manipulation. There was so much good stuff to see, including this old school schematic that was done by hand with tape.
The kitchen sink at Signal Culture was missing a faucet handle so I made them a new one. I love sneaking plain, functional objects into public environments where they become useful and invisible. Unlike more precious art objects, these items are designed to be handled and forgotten (even as they give me a semi-permanent presence in a space).
One of the great things about the Signal Culture residency is that they understand tool making as a creative practice. I brought along my 6040, an aluminum mill that I bought from China via eBay. Though I did not fabricate this mill myself (like we did with DIYLILCNC), the 6040 came with no instructions, so I’m applying all my DIY know-how to getting it up and running. I’ll use both this blog and github to document the process.
Today I got down to business on a new Raspberry Pi project. I started with the following parts:
- RPi 2B (w/ 8G NOOBS)
- USB wifi dongle
- RPi Noir camera board
- Monitor, keyboard and mouse (just for setup)
Following a clean install* I set up my RPi to enable SSH and the camera. If your RPi system software is already installed, you can reach these features by entering raspi-config in the Terminal. I also got the wifi dongle talking to my network. Camera installation is really simple. See this link to make sure you get the ribbon cable polarity right.
Now we install RPi-Cam-Web-Interface. The documentation is a little hard to follow, so here’s a condensed version:
- sudo apt-get install lsb-release
- lsb_release -a
- Confirm OS code name is “Jessie”
- git clone https://github.com/silvanmelchior/RPi_Cam_Web_Interface.git
- cd RPi_Cam_Web_Interface
- chmod u+x *.sh
- Enter the IP address of the RPi into a browser from another computer on your network. You should get a page full of options and a live image from the camera.
Ok! Next time I’ll talk about adding UV LEDs.
*After one unsuccessful run at this project, I ran into problems trying to reinstall NOOBS from the RPi boot screen. You’re supposed to be able to do this by holding shift, but I couldn’t get it to work (even after trying all the voodoo like rapidly pressing both shift keys in alternating fashion). I wound up downloading a fresh copy of NOOBS and copying it to the SD after wiping it with the OSX disk utility. Everything worked perfectly after that.
The good folks at Element14 got in touch after they read some of the Raspberry Pi tutorials on this website. They offered to send me some parts for a project, so I decided to start with a networked baby monitor. I’ll post progress as I go!
AT&T tells me you can’t trust sites that test your internet speed. When I had a tech out for repairs today, I was able to ask him for live stats to compare to a few web services. This one matched the AT&T test almost exactly.
My colleague Greg Corness at Columbia College just turned me on to Defamiliarization, or the presentation of common things in an unfamiliar way. This leads to reevaluation of assumptions, and describes my research really well. Here’s a recent article dealing with the topic through the design of the kitchen.
Google has instructions on how to do this, but they kept confusing my students. Here’s an attempt to make the process clearer (and more useful – we’ll be sharing folders instead of pages). Note that this feature will cease working as of August 31 2016.
- Log in to Google Drive. This may not work from an institutional account like those we have at Columbia College. Safari can also try problems, so maybe try Chrome.
- Create a new folder
- Right click this folder and select “Share”
- then “Advanced”
- then “Change”
- the “On – Public on the Web”
- click Save, then copy the “Link to Share”
- Paste this link into a plain text editor, then delete everything to the left of “=” and the right of “&”. Delete = and & as well.
- This is your Document ID
- Now put www.googledrive.com/host/ in front of your Doc ID
- Now you’ve got a live URL! Type it into a browser and see if it works.
Every time I update WP I lose the changes I made to the WPBC plugin. I know there’s a better way to do this with theme children or something, but here’s a note to self for now. Maybe you’ll find it useful.
Plugins > Editor > Select Plugin > WP Bootstrap Carousel
Comment out the following:
$carousel .= '<h3 class="carousel-post-title">' . $item->post_title . '</h3>';
