SparkFun Electronics will be closed on July 3rd, 2015 in observance of Independence Day. Any orders placed after 2:00pm MT on July 2nd will be shipped out after the weekend. Thanks!

  • The short options is useful to zero the system minimum resistance if you were to use this as a precision load. But this can’t really offer precision measurements anyway.

  • Unfortunately this is a very poorly designed resistor box with accumulating errors everywhere. This should only be used for rough measurements…

  • The power supply does not need to provide 2.8A. It only needs to provide at most 700mA, actually a lot less since you won’t be running them at the full current.

  • Does anyone know if there is a variety of this LED in a 10mm diffused format?

  • 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.

No public wish lists :(
