  • 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?


  • Referring to the wikipedia page on Parylene, there is indeed plenty of chlorine in the product.

  • Yes - the leds are independent of each other. You can energize them one at a time or both together. I bought one of these a few years back and just got it out yesterday to wire to an Adafruit Pro Trinket with their USB volume control software. I added a bit of pwm code to run the leds from green to yellow to red as the volume goes up.

  • There’s a bug on the survey question about the users preferred programming language. I didn’t check any box but filled in the “other” field. Then when trying to go to the next page, it said I must answer that question. So I clicked the javascript box but put a note that I don’t actually use it. I sent a note to customer service about it.

    Side issue: assembly language was not included as a choice; looking forward to see the results of the survey published here.

  • Just gonna ignore the few haters posting here and say “Nick: FANTASTIC POST!” And to Sparkfun: what a great company to be this inclusive.

    This is why I totally continue to support Sparkfun and Adafruit! Both companies support freedom for everyone, not just the supposed ‘mainstream’.

No public wish lists :(
