    Can someone please comment on the price of these units? Were they always $189? Or where they used to be $99?

    This would have made the RGB Fiber Communication experiment much easier!

    Yes, the detector has three identical photo-diodes with red, green and blue optical filter arrays in front of them.

    The RC filters convert the PWM to analog and thus the constellation is 8-PAM. If I were to leave it as PWM and detect the duty-cycle directly, then the constellation is PWM with 8-duty-cycle. Also, thanks for the kind comments.

    I think they already do. With TX and RX modules as well.

    Hi! This is Shahriar, the host of The Signal Path. Thank you Sparkfun for featuring one of my videos. I’d like to point out that wavelength division multiplexing (WDM) is a common practice for increasing data throughput of fiber communication systems. Multi-Terra-bit-per-second data rates can be achieved using this technique. My video is aimed to illustrate the idea using visible wavelengths and for educational purposes.

    Although I am happy to see this type of giveaways, I absolutely did not have fun with this one. It was a frustrating experience which must have wasted tens of thousands of man-hour effort during a weekday. After 10-minutes I had to give up because I could not justify the time. Regardless, I appreciate Sparkfun and enjoy their products all the time.

    Are the througholes all independent or are they wired like a breadboard? I personally think the breadboard style is much more useful.

  • Product PRT-10746 | about 2 years ago

    Very useful!

  • Product DEV-10864 | about 2 years ago

    All this Arduino shields are great, but I wish we would get more generic type development boards, perhaps with PICs.

No public wish lists :(
