  • 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…

  • Ok, the very first thing I saw was a person, despondent about the IOT, decides to end it all by hanging.

  • This has been a long time in arriving yet it ain’t here yet - it’s back ordered. So… a) What is Sparkfun’s best guess as to delivery dates? b) Does the entire ESP32 device work as advertised? For example, does Bluetooth work? Are there drivers for it? c) Any other caveats customers would like to know about before ordering one?


No public wish lists :(
