  • Nice work! Plus great job on the Baxandall analysis in LTSpice!

    Man, it’s been years and years since the last time I got to say ‘Baxandall’!

  • Not to mention this from the eff.org: https://www.eff.org/deeplinks/2017/04/trump-signs-bill-roll-back-privacy-rules-law
    wherein you will find this paragraph:

    That measure not only repeals the rules, it also prevents the FCC from writing similar rules in the future, throwing into question how much the FCC can do to police ISPs looking to trade off their customers’ privacy for higher profits. Because of the current legal landscape, the FTC can’t police ISPs either, leaving customers without a federal agency that can clearly protect them in this space.

    So, yeah, I’ll go with the eff.org version over your twisted fever dreams… referring here to the original post by #831693

  • There is no fine print on the bottom of the statue of liberty.

  • None just yet but have been getting interested in synths lately. I live mostly in the PIC archipelago plus have a long background in the arcane arts of analog. I just made a silly touch sensor from a brooch this one and when you touch it, it plays an MP3 file.

    My grandson is attracted to this stuff so I am constantly on the lookout for topics that he can explore. He seems to have some musical intuition plus a younger sister who is always right there watching as well. They are never too young to start and synth sounds appeal to them.


  • Very nice presentation! Is the source code for all these things available on the net? Also, does it only work on Teensy hardware?

  • Little children put nearly everything in their mouths; think of the leds getting chewed off and sticking in the throat of a little one… hilarity ensues.

    I wouldn’t give it to any child younger than 5 years of age let alone the 5 day old granddaughter I have. Just sayin…

  • First thing that came to mind was when a bug in the code makes the laser point up to the sky, into the cockpit of passing aircraft. Authorities quickly notified, knock at your door.

    Hilarity ensues.

  • Ten thumbs up for Colin Furze and James Bruton’s web sites; my grandson begs me to run the videos for him. Now gonna have to watch the others ones you posted!!!

  • End of the day, just read this article. In a word: OutStanding! Yeah, maybe that was two words.

    Barry’s write up is right up there in quality with Jim Williams (R.I.P.) apnotes he wrote for Linear Technology! I recommend that anyone interested in this stuff print it to pdf and read it at least once a year. As I read through it, I found myself saying “I hope he covers such and such” and a page or two later, he did. THIS STUFF is what has replaced analog electronics; I’m an analog dog from way back but since everything is done with micro-controllers these days, you need to know how the tools of the trade work and Barry has shown the way. Input/output, filters, math, signal processing, using tools to get the job done, integer math, and on and on.

    Plus: what a great write up. It’s one thing to understand it and do it; it’s another thing to communicate it to the rest of us and Barry did just that.

    So: thank you to Barry, thank you to Nate and thank you to Sparkfun: keep doing what you do!!!!!

  • Yup, got the same unit in my living room as well. And the lights are all gone too. Been thinking about doing this for years…

No public wish lists :(
