  • We have several products that have gone through the FCC throughout the years (all intentional radiators, all used in airborne applications). The costs you outlined seemed very reasonable. This is probably one of the best summaries I've seen and I am very impressed you published it (kudos to you). Since going through the process is pretty time consuming, many companies consider the experience more inline with intellectual property (just thought others that are not as familiar can really appreciate what you've done). We normally go to a local place for testing, but I know of one product that was more "commercial" and went to one of the "aggregators" so the testing was actually done in China. I can tell you that one thing we learned is that some test houses over there (I won't say all) take very detailed pictures and documentation of everything they test and later on pass that information to local design houses. It is kind of the "cost of doing business" with companies over there (but you probably knew that already).

  • Whoa turbo … this thing looks wicked. They called this impulse buying.

  • I got the previous version of the Blackboard and the newest (rev C). It is a really good dev board. The USB-C is a plus. The Qwiic support if very well thought off; the Qwiic connector contains the level translator for the +3.3V Qwiic system, but the SDA/SCL lines still maintain +5V support. For the Uno line, this is my new go-to.

  • On Windows 7, 8, 10, the device was not recognized automatically. My recommendation is to install Zadig before using the device. Run Zadig and plug the Logic device (it will pop-up in the Zadig drop-down as unknown device). Within Zadig; rename the device to something meaningfull (e.g. "SFE USB Logic Analyzer" - this is the name that will show up in Windows Device Manager), and install the WinUSB driver. From there on when you run Sigrok Pulseview, the Logic device will show up as Saleae Logic Analyzer.

  • What is the difference between this one and the SPX-15057? Is it just that going forward this is the commercial version that will be available?

  • While helping someone else to use OpenScale I decided to build a quick prototype of a small weight scale. I create a brief article on it (including code) on the following link for anyone that finds it useful.

  • Thank you for this excellent article. One would hope it would illustrate how isolation or protectionism is not the answer. One would hope that most people in the US had enough education in history to know that all the great empires (Greece, Rome, England, add your favorite one) mostly failed not necessarily because of their armies, but because their economies were unsustainable. Because they stopped adapting and decided to close themselves to the outside. One thing that has maintained US as a world economy is not that it has the smartest, richest, or hard working people; it is that it has known how to intermix those type of people at the right times. It has been able to innovate, evolve, change, but always with the mind of making money.

    Now we are heading straight down the annals of history; right down to join other have-been empires. I guess we are not as educated as we thought; either that or our history teachers failed and our ego is so big that blinds us from following what made America great.

    England here we come, ready to join you as a once-great-empire full of older people and a stagnant economy. Again, great article, and I would hope that true capitalism runs rampant for the next year or two and just swallows these attempts of isolation or protectionism and buries them so deep that they will never ever come out.

  • I love this product. Next to the perpetual motion machine, this is truly revolutionary. Kudos to the SFE team for their continued innovation. These things are just awesome. Can't wait for the 120V version that will allow me to hookup appliances together.

  • Thank God you decided against using Parylene. I am not sure why you think this is easy to remove or who have you really consulted on this. We normally use acrylic type for most airborne electronics (Humiseal 1B31 LOC) for its ease of rework and low environmental impact (as well as human impact - the people that have to work with it). We only use Parylene where we have to make absolutely sure moisture needs to be completely sealed off (i.e. air pressure sensors, fuel measurement systems, military avionics). I can attest from experience there is no chemical we can use to remove it (we have to sent the coated electronics to a specialized house to do this); so the only other option to remove it is the Xacto knife (and oh how much fun can that be). Seriously, if you want to look at coating take a closer look at acrylic types as they are friendlier in every way. Parylene is awesome for its purpose; but its purpose is certainly not general electronics (think space shuttle, F15/F16, high reliability / high criticality equipment).

No public wish lists :(
