Bio

I started at SparkFun in September of 2007 as an assembly technician. My experience in electronics had consisted of only running sound equipment for my band and fixing the occasional broken guitar cord. After only a few days on the production floor, my skills with a soldering iron improved dramatically, and I was building beautiful little widgets. It wasn't too long before I started wondering how all these circuit boards actually worked. Whenever I had the chance, I would walk across the hallway to the engineers and ask for 5 minutes of their time. I learned words like micro controller, source code, op amp and many more. I was hooked.

My first project was an analog headphone amp. It was something I could use as a performing musician. This has since kept me busy on week nights (and most weekends) as I've grown my own business around audio products for musicians.

While perfecting my headphone amp design, I got into other DIY projects too. Before long, I was in my front lawn with my laptop and a few servos. I was hacking my sprinkler system. With some active pressure control, I was able to make my sprinkler shoot a perfect square. My neighbors thought I was a crazy :)

Little did I know that taking this position at SparkFun would open my eyes to a new favorite creative outlet, DIY Electronics. I get super stoked about a lot of things, but from the moment I felt that initial spark of interest, I knew this was something very special. I was learning tools that would allow me to truly harness my inner inventor.

In the last few years I have focused my energy at SparkFun to designing more efficient testing equipment and providing feedback to the engineers on how we can better design for manufacturing and testing. I can hardly call it a job, because I love it so much :)

  • Hey 773, Nice to hear from you! Indeed, the IC is a pretty darn cool facility. Everyone on their staff, the mentors and students are all wonderful to work with. It has been an honor to work with them on this project. I'm astonished by this team's dedication and how far they have come with their engineering skills. This was one heck of a huge PCB to layout and assemble by hand!

    PS not sure if you saw saw these other posts over the past few years, but here are a couple more blogs we've done about the IC:

    Project Canary: Atmospheric Research Takes Flight

    Aerofest 2019

  • The ATMega328 has an internal oscillator. We program the fuse bits to utilize this at 8MHz. This is done in production just prior to programming the bootloader and Simon firmware. Hope this helps!

  • Thanks for your feedback. We will definitely consider the 1015 as a future project. It would be a drop in replacement on the PCB layout, and a minor addition to the Arduino Library, however, sourcing the modules (and all parts these days, really) is another challenge.

    Also, I agree, most RC airplane's are flying much faster, and so it would most likely be only useful on thermal gliders and slow slope floaters (maybe some VTPR in lighter conditions, but even those could max it out on big dives). I've decided to remove that suggestion from the description for now. I might give this a try on my Ahi and report back.

  • Hi there Kraxner, Sorry, but due to the fact that this module does clock stretching, we won't be creating python/raspi support.

    It doesn't have much (in terms of setup), so basically, you just take readings from it, and then convert that raw reading into m/s or mph.

    If you wanted to create your own simple I2C read python example, then you might be able to use this by slowing down your clock speed way down (like 5KHz or even 1KHz). It looks like some people are able to use I2C peripheral boards that do clock stretching with python in this way. Sorry for the long winded response here without the best news, but hope this helps.

  • Hi Radiohound, Sounds like a cool project! Unfortunately, we don't have any immediate plans to sell the 1015 version. Could be something down the road, but how long I really can't say.

    If you can rig up some sort of airflow intake system ahead of the sensor (that is smaller than the area of the sensor intake), you can read faster air velocities. Maybe a fun 3D printing project? However, this would take a bit of experimenting and data-intake to get accurate conversions.

    FWW, during my prototype testing on this design, I put the sensor in various PVC pipe diameters with some known air velocity sources (created by thinner pipes hooked up to oxygen flow meters and compressed air) and the readings matched the planned conversions quite nicely.

  • Hi There, Sorry for the delay in my response here, but glad to hear you got it working!

    I see you also posted an issue on the forums about the Pi not finding the boot hex file (even though you had verified it was there and had correct permissions). How did you end up resolving that issue?

  • Hi Dom, Sorry, but this mic's datasheet says it will only work from 60Hz to 20KHz. Also note, that the op amp design has an upper frequency -3dB roll off at 19.7KHz. Sounds like a cool project though. If you want to, you could try reaching out on our forums to see if anyone else might be able to recommend a mic with wider frequency response. https://forum.sparkfun.com/ Good luck! Pete

  • Hi There, Please double-check that you are using the latest driver on the CP210X. If you use an old one (or the one that windows automatically installs), then the auto-reset does not work. See this drivers section of the tutorial for more info and links.

    Hope this helps!

  • Hi Nuri, The ATECC508A does not encrypt or decrypt messages. It only creates signatures. In the examples we have provided, the message is sent as clear text along with a signature.

    The keys are only used to create and verify signatures.

    Hope this helps! -Pete

  • Hey 720, Wow, nice work! Your layout is great and I like what you've done with your software reorganization. Our repo has a ton of code included in the "test.py" module, and it makes sense to split it up. Your state machine is a very clean approach. It is really wonderful to see this project grow into another - the true open source success story. Thanks for sharing!

    PS I'm curious, what kind of projects are you planning to use your LEMPA on?
