  • I made a watt meter using electric imp and ADE7953 energy meter chip. As many know, the old light bulbs have nearly a perfect 1.0 power factor. You can see some examples here http://themzlab.tumblr.com/wattmeterwaveforms

    The Cree light bulb that I checked appears to be attempting power factor correction and achieves 0.97.

  • It has happened to me. Some old and slow-moving software was written for IE and only IE back in the day. At work you are stuck with those tools for the moment and so yes, this happens. For example, ADP suggests IE, FF or Safari, no mention of Chrome. It used to only work on IE but now I use it with Chrome.

  • good, but I laughed the most at the one with the Yakov Smirnoff reference

  • all right, the first person that falls asleep…

  • Actually, technically it does work this way. A finite amount of energy or power causes the wind to flow. If there is sufficient drain on this the wind will slow. I don’t know about the relative magnitudes but wind turbines do subtract from the power of the wind.

  • no, it will not : )

  • I like this board and the Imp. I got it up and running in just a handful of hours. I had to cut the “CS” trace because that pin was already used by my system. I also cut the traces that were defaulted for software serial and solder-jumpered the UART 57 (pins 5 and 7) of the Electric Imp to the Arduino. I am using Leonardo boards so the hardware UART was available.

    I started with the code by Jim Lindblom and modified it slightly to work on my system.

    Now my Arduino-based testing machine is on the web. Awesome!

  • I used this with the SEN-08554 IR receiver and with a Windows Media Center compatible remote. The combination works well so far in my tests. I have set the SIS-2 to discrete button mode so that I can use it to toggle power to my media center PC. I will use an Arduino board between them to handle the logic of commanding the power switch on the computer and to flash a LED to tell me the status of everything.

    The IR Receiver is optimized 38kHz and the WMC remotes are running at 36 kHz but this does not seem to be a problem so far.

    What I have working so far is that one remote control button will turn on the output regardless of how many times I press it. The other button will turn off the output regardless of how many times I press it.

    I hope this little bit of information may help others…

  • I wouldn’t think so. The linked data sheet states this:
    Operate times: 15 ms max actuate, 10 ms max release

  • Very nice work!

No public wish lists :(
