Now that I’ve mastered (!) publishing sensor readings from a Particle device and visualizing them with ThingSpeak, it’s time to step up my game a little bit. I have an old BMP180 temperature and pressure sensor that I thought was toast. I’m glad I didn’t throw it out because it seems to be working well.
I was interested in this sensor because it reports two values. If I want to send both values to ThingSpeak using the Particle tutorial, I would have to set up two webhooks (and possibly two channels). That seems like a lot of work. I sought an alternative. The particle community has several discussions (such as this one) that show how to do it.
I am continuing my exploration of the particle devices. This time, I have a Xenon that is connected to a TMP36 temperature sensor sitting in my office at home. Every second, it updates a variable on the cloud that contains the current temperature of my office.
I recently purchased a few particles in part because they are little devices that are named after elements that allow you to connect sensors to the internet; what about these items does not scream BoBtheChemist?
I’m currently running through some tutorials and am sure to forget a thing or three, so I’m going to chronicle my experience in hopes to (a) have a central repository for my work, (b) show that my website does have some activity (c) possibly serve as a resource for the 1-2 bots that frequent my website.
Tomorrow starts the new semester for me, and I finished my course prep (well, tomorrow’s activities anyway) so I figured I would celebrate with a little creativity. Not too long ago, I came across the activity where you can make a t-shirt iron on by drawing on sandpaper. I have sandpaper, some old t-shirts and I splurged on an 8-pack of crayons ($0.67 at Walmart) so I figured I would give it a go.
This year is all about the periodic table, so I wanted a periodic table design. One trend that I particularly like is the number of stable isotopes, which very clearly shows off my favorite element – technetium – because it is the lightest element without any stable isotopes. Technetium’s claim to fame is that it’s the first element to have been synthesized (in 1937) and therefore it is, in my opinion, the element of makers.
