It's like clap-on, clap-off, but nerdier.

Processor Interrupts with Arduino

December 11, 2018

What is an interrupt? In a nutshell, there is a method by which a processor can execute its normal program while continuously monitoring for some kind of event, or interrupt. There are two types of interrupts: hardware and software interrupts. For the purposes of this tutorial, we will focus on hardware interrupts.

How to Use a Hot Air Rework Station

April 10, 2018

Hot-air stations or heat guns are very useful tools and are essential for any electronics workbench. When working with or building printed circuit boards, there is a lot of room for errors to be made. Have no fear though, there are ways to remedy this with a hot air rework station!
  • I fail to see the connection between supportive family/mentors and special treatment from “powerful corporate interests”. I don’t look for special treatment or preferential benefits. The work still needs to be done, and it still needs to be up to snuff, regardless of who you are. I am merely stating what I see and hear. There are bullies everywhere - there is no point in looking for or worrying about them. You do your work in spite of them.

  • Given my personal experiences, I would hesitate to agree with your initial premise that this means women are pursuing their own interests. I have, throughout my life, been repeatedly discouraged from going into a “man’s field” and have flat out been told that women can’t do math or engineering. My collegiate classes had 250 guys… and me. I still see it; I still hear it. Little girls who ask me about what I do and then tell me “that’s boy stuff”. Or the boys on my kiddo’s soccer team who couldn’t believe that I was an engineer. One of them actually asked me “They LET you do that?”. The persistence of our traditional social constructs is far-reaching and to be honest, it is disheartening for me.

    I was extraordinarily fortunate to have parents who recognized and fostered my interests and abilities, allowing me to follow whatever path I wanted. I had mentors who did the same. But the more I see and hear, the more I realize that my experiences are NOT the norm; and I will continue to try to get all the kiddos in my family (especially the girls) to be nerds like me. :D

  • That speaker would be a bit heavy for a kitty. We have a lighter “thin speaker” (COM-10722) that might work though! The boards themselves are fairly compact, with a smaller battery perhaps?

    Hmm. I need to find a cat to prototype for now… :D

  • Hello! I re-read the experiment and looked at the code and I think the verbage could be re-worked because it is a bit confusing. We read resistance at 16 different loci and then use those values to calculate the cardinal directions we list in the experiment: N,NE,E,SE,S,SW,W,NE. In the makecode package, the standard deviation on these values is +/- 10 which gives me pause when looking at gradations of NNE, ENE, ESE, etc. I’m logging an issue to look at the statistical analysis to verify we can get consistent accuracy with these extended directions. If it makes sense to update the makeCode (and the experiment) we certainly will. Thank you!

  • True. I chose this method because I was teaching the basics to young'uns. I also had some of the parts just sitting around so it worked out to be pretty inexpensive as well. Win win!

  • Heads up! The tutorial is now live!
