  • News - Enginursday: Time-lapse w… | about 5 months ago

    Here’s the script I used to pull the images:

    $ cat getmsh
    #!/bin/sh
    wget -O /opt/home/eric/mshimages/mshvolcanocam-`date +%d%m%g-%H%M`.jpg http://website.us/images/mshvolcanocam.jpg
    

    The important bit is the command substitution in the filename using date +%d%m%g-%H%M

    using the crontab example above, you could do:

    */5 6-20 * * * raspistill -o /path/to/image-`date +%d%m%g-%H%M`.jpg
    

    I then used transcode to make the movie at the end of the month.

    I had the same thought. Years ago, I had a script to scrape the Mt. St. Helens webcam image and store it. I used cron to run the script every 5 minutes, and at the end of the month another script ran to make a timelapse for the month using ffmpeg. You can concatenate the date/time into the filename when you save the image. If I can find the script when I get home tonight, I’ll post it.

    Ideas for making the aerial competition more challenging (and even more entertaining): 1. Burning rings 2. Anti-aircraft fire (possibly re-purpose the atrium nerf-launcher?)

    Agreed, the NEETS modules are very handy for basic learning. It helps that they are broken up into discreet topics, so you can skip the ones you don’t need at the time. I think I still have a hard-copy set of NEETS modules in the basement somewhere from youth.

    AVC is taking on a bit of a Mad Max feel this year…

    You guys need to come up with some hidden cameras to capture your pranks without arousing suspicion.

    Also, I’m jealous of Pete’s office. It’s way cozier than my cubicle.

    Either put all of the elctronics (including battery) on the rotating part, and control it wirelessly, or use a slip ring to pass signals. Ladyada did a slip ring tutorial/teardown video not long ago.

    Actually Robert, there’s those of us that have been around a couple of years that also think this is a stupid idea. I would have liked the quiz last year if the website had stayed up for more than one question, and didn’t tell me I was wrong when it errored out.

    Is that an ESD-safe puppy? And is that dog tranquilized? It seems way too calm for a puppy.
    How are these wireless TX/RX pairs different from the ones offered previously?

    I, also, was disappointed that he didn’t blow up a electorlytic cap or two. Nothing like an object lesson to drive the point home. And to demonstrate that caps store energy, charge up a couple big ones and toss them to coworkers.

No public wish lists :(
