A spooOOOOoooky project!

This is a fun one.

It’s also a testament to how nifty and easy it is to quickly whip up a project with Arduinos, provided you have enough of a “critical mass”, as I’ve called it before, of other stuff that you might end up needing.

How was this one born? Well, there was a Halloween grad student party our school was throwing, on a Friday night. It’s… honestly, really the type of thing I, or any grad student, should go to. We’re mostly isolated from other grad students, and these parties have typically gotten pretty raucous when I’ve gone to them. However, that night, I really wasn’t feelin it. I got home from work/the gym kind of late, hadn’t eaten, and the party was downtown. I think it might’ve also been raining or something, adding to the “I don’t want to go out” side of the scale. read more

Getting back on the horse…er, Python

As of this writing, I just defended and I’m considering various options for what I’ll do next. That’s a whole other story, but the important part for this post is that, probably for whatever I do, I’ll be coding.

I’ve coded a decent amount in my life. I started with dinky web stuff wayyy back, then picked up a now-tattered and probably outdated “C++ for Dummies” book in highschool. I did small programs with that, as well as some silly things for crappy AVR projects I did. In college, I used mostly Java because that’s what the computer science classes I took asked for. Towards the end of college, though, I was working on my own research, and used C++ instead (why? I honestly don’t remember. Wait, I just did! My advisor had heard of some multiprocessor module for C++ that he wanted me to try, so that’s why I didn’t stick with Java). read more

Low power Arduinos, part 1

As part of an ongoing project, I wanted to see how low I could get the power consumption of Arduinos to go. The reason is as follows. When getting back into Arduinos a few months ago, I wanted to try a telemetry project of some sort, collecting data remotely and sending it back. Ideally, the idea would be to collect data from different places and analyze the aggregate in some cool way, but that’s a story for another post.

The point I was going for, though, is that I wanted to put these Arduinos in places that wouldn’t have constant access to power, so that already means using a battery. Using a battery to power an Arduino isn’t a big deal (plenty of people do it for portable projects), but once you’re looking at long term powering without recharging, it’s a different story. read more
