  • I love you Sparkfun, but I think you're in the wrong here. Anyone in this industry, especially you, should have seen LOTS of fluke DMMs in the past. What you tried to import looks like a clear and explicit knock off. Being engineers, I can see how you may have not understood that this was an issue (I wouldn't have really though of it either), so I do empathize. But part of the reason this trademark may already look somewhat generic is because it has been diluted by similar but not quite infringing designs already so everyone thinks "oh yeah DMMs are yellow". I'm just seeing a lot of one sided comment and wanted to provide a voice to the other side.

    Also, fluke isn't some evil global megacorp. They became number one because they were good, they're a USA company (like sparkfun). Sadly though, they have started outsourcing a lot of their manufacturing to china recently, but their best stuff is still made in USA (last I checked).

  • link is broken. Anyone else have a link?

  • Any Idea when this will be back in stock or recommendations for similar rework stations?

  • Another thing you can do is solder male headers to the GPS and female headers onto your board. I had to do this because board real-estate was at a premium and I had to put components between the pin rows. Also this is an expensive part so being able to move it to new board revisions was nice.

  • It's not a bug in the arduino. ints in avrgcc are 16bits. 38400 in binary is 1001 0110 0000 0000. Note the overflow into the sign bit! So the const int baud really has the decimal value -27136. When you use that to call begin it gets cast to a long but retains the negative value (which is the correct behavior). If you want to use a const instead of a literal value, you can define it as a const long and you should be okay. If you do use a literal value writing it as 38400L is best because you're explicit about the type.

    Note that literal values are, by default, interpreted as ints! Here you are lucky with Serial.begin(38400) working at all because the compiler can figure out from context that you meant 38400 to be a long!

  • nice! Thanks for the quick, accurate info! Honestly, this is why I love sparkfun so much. now if you just had some in stock... ;)

  • Hi I have a couple questions that don't seem to be explained here.
    1) How is the firmware updated/changed? 2) whats the difference between the firmware versions posted. from what I can guess the standard version will log to SPI still. The internal logging logs to the internal flash. But what does "high dynamic range" really mean in this context? and how do you define a sharply turning vehicle? 3) what is the difference between booting from FLASH and ROM? Is there a different "standard" version that is non-erasable? if so what does the rom firmware do differently?

  • Actually, the output frequency is linearly proportional(ignoring the tiny offset) to iridescence (power-per-area) in the range of 1Hz-1MHz. This means you can read light levels across six orders of magnitude. It's tough to read three orders of magnitude out of a typical photodiode.

No public wish lists :(
