HackerBox #0029 Field Kit Updates

I’ve customized the items in the HackerBox Field Kit and explained everything in this video.

You can find the example code I put together for all of the modules in my hackerbox-29-field-kit GitHub repo.

I plan to keep the kit in my backpack, especially for trips up north when I visit family. Maybe I shouldn’t take this with me on flights though. Have you ever travelled with a bunch of wiring and electronics parts?

April 14, 2018 Storm in Saginaw, Michigan

On Thursday it was 64° when I ran outside. Then we had a winter storm come through the weekend.

Since it’s rare to get a storm this late in the year, I thought it would be neat to document it.

My makeshift ruler and stand was a complete failure; it blew over, spun around, and wasn’t readable. I’m happy with the rest of the project though. I really like the worms crawling around, seeing the water freeze, and how the lines of the bricks come through.

I used a Raspberry Pi Zero W and the camera module.

In order to get images for the time-lapse I added cron job that ran a bash script every minute, which in turn called raspistill to capture a photo. It was very easy to set up. Here is the bash script.

#!/bin/bash

DATE=$(date +"%Y-%m-%d-%H-%M-%S")

raspistill -vf -hf -o /home/pi/time-lapse/images/$DATE.jpg

This is the line I added to my crontab.

* * * * * /home/pi/time-lapse/capture.sh

Before transferring all of the images to my Mac, I compressed the images folder.

tar -czvf images.tar.gz images

Then, from my Mac I could grab them by doing a secure copy.

scp pi@pi.local:/home/pi/time-lapse/images.tar.gz images.tar.gz

In order to stitch everything together, I imported the images into iMovie, changed the crop style to fill, and set a 0.01 second duration.

JAY-Z & Letterman

Last night I watched JAY-Z on My Next Guest Needs No Introduction with David Letterman. I can’t recall ever watching an interview with JAY-Z before this, so it surprised me when he seemed a little awkward and uncomfortable. Especially for someone who might be the best artist of our generation. He had such a different presence than I got from Dr. Dre, another hip-hop legend, in The Defiant Ones. It’s quite possible it was because of editing or the format of the show though.

I’ve been listening to JAY-Z’s music for a long time, but never knew much about him. It was good watching him talk about his life and experiences as well as some of the tough conversations our country is having.

Photo Challenge: Awakening

I’m struggling with the “awakening” theme for this week’s photo challenge. While it’s the middle of April, spring is nowhere to be found here in Michigan. It’s 39° outside with a big winter storm starting in the morning. Nothing is growing yet. The best I could come up with is hope, which I what I thought when I saw these rose bushes at Sam’s Club.
