tiny little stack of LAMP
Monday, April 8 2019
A light rain was falling this morning as I got going, and even though I got up with the 7:30am alarm and stopped at the Hurley post office (a little 8:00am) to mail off some of the books people had bought from Gretchen's website, I was the second person into the office. The first, as usual, was Morning Dave, the guy with the stand-up desk who usually comes in super early and leaves at 2:00pm or 3:00pm.
I had my leftover Beyond Burger for lunch and then hopped in the car to run some lunchtime errands. First I drove to the Williams Lumber north of Rhinebeck to see what sort of esoteric vent pipe fittings they had in stock. The most intriguing of these was a fat rubber one designed to be installed as a plug. This might've come in handy had I not found a properly-sized ABS fitting online. The hardest thing to find for this project has been a tool suitable for cutting an old pipe from the inside of a fitting. But there at Williams, they had that tool in a nice range of sizes. They also had a great many more options for woodstove gaskets than I'd been able to find at Home Depot or Lowes. It's taken me awhile to realize this, but it's true: the mom & pop hardware stores are geared towards a more professional clientele, whereas Lowes and Home Depot care more about the home do-it-yourselfer. So you're just not going to find esoteric tools and equipment in a Home Depot. But a guy who does plumbing for a living needs to have easy access to obscure equipment.
My next lunchtime errand was to Hobson Window, that glass place in Red Hook where I'd ordered the two panes to replace the broken ones on my big homemade solar panel. When I walked into the store today, nobody was there but a somewhat overweight golden retriever. He or she wasn't concerned about me at all and was happy to have his or her ears scratched. Then a guy showed up who told me to pick up my glass at a building in the back. The guys there were unusually unpleasant, which is why, I suppose, they cut glass all day instead of interact with customers. One was running a grinder while the other gruffly "helped" me get my glass, though he began by demanding to see the paperwork the guy in front had not given to me. But when I described glass that was on the ready rack, he became a little less belligerent. But then he had to yell in order for me to hear him over that grinder, which made everything unnecessarily stressful. It was good to get the fuck out of there.
By the time I returned home (a little before 5:00pm) the day was so warm that the windows and doors of the house could be thrown open to let in that glorious springtime air during the brief time it isn't full of flying insects.
I've been wanting to set up another Raspberry-Pi-based surveillance camera, so the other day I got a cheap Raspberry Pi Zero W. I didn't want to bother with setting it all up, so I hoped I could just make an image of the existing SD card in the EyeSpy Raspberry Pi I've already built, which can already do things like show sensor data on the webpage which shows the video stream, and stick a copy of that in the Raspberry Pi Zero. This evening, I was delighted to discover that this does indeed work. Unfortunately, the Raspberry Pi Zero requires a different camera interface, so I couldn't get a second EyeSpy working immediately. Ultimately, I'd like to have multiple EyeSpies all logging data (and perhaps controlling certain things like lighting) in multiple locations. Since a Raspberry Pi can host an entire LAMP stack, I can use some of my existing MySQL visualization tools to display historic data.
