Wind Turbine (50W) Loaded Results

Wind Turbine (50W) Loaded Results

Update (03/26/14):  The Wind Turbine was deployed down in Curacao two weeks ago.  The actual data from the Turbine matched this article quite well.  About 60-90ma at 15 MPH.  Not much (and not nearly enough to run the box – […]

Matplotlib, Raspberry Pi, MySQL, RasPiConnect and Project Curacao

One of the things we are using the Raspberry Pi on Project Curacao for is to generate graphs.  Yes, We know we could ship the data to another server and generate the graphs there, but since we have a nice […]
Windstorm on RasPiConnect

Windstorm on RasPiConnect

Here is a screen shot of RasPiConnect capturing the wind storm that came through last weekend.  We had the 15W Wind Turbine hooked up and reporting through the Project Curacao software.  It was fortuitous that the wind storm came through. […]

pi camera / raspistill problem behavior change

Yesterday, we installed all the new updates and upgrades to the Raspberry Pi in preparation for the trip to Curacao (we leave at the end of February).  When we looked at the power system display this morning, we were surprised […]

Project Curacao / RasPiConnect Video

The folks over at Milocreek.com (Authors of the RasPiConnect App) asked us to put together a short video of Project Curacao focusing on the control panel (done in RasPiConnect).Here it is:

    Just got my WeatherPiArduino and WeatherRack. I hope to set up a Citizens Weather Observer Program station. Soldering in the DS3231 blocks the data and clock pins for the I2C. I installed it along with an AM2302 in a proto shield instead. The Arduino with instruments overloads my Raspberry Pi USB bus locking up the keyboard and mouse. The Arduino required an external power supply. I am having problems with the Sketch. Libraries time.h and elapsedMillis.h were missing. Defines are for interrupts on pins 18 and 2. Connections are on pins 2 and 3 in your wiring diagram.

    I would like to know where you put your code after designing a RasPiConnect screen. Where is the command file called from to get the button responses?
    I see you use a command file, where does the commands come from? Does the RasConnect send them to the command file?

    Thank you

    how do you integrate your command.txt in your MouseAir program into RasPiConnect Local.py file. Where do the command = f.read() come from?

    I see that the SunAIRPlus is out of stock on Amazon, any idea when it may be back in stock. I’m trying to build a solar project and want the monitoring capabilities of the plus.

    Thanks,
    Geoff

      Geoff,

      There are 7 more heading to Amazon and they should be there on or about March 28th. We got caught with a big order from back east. We have ordered more and the next batch of 100 should be here in about 3 weeks.

      The 7 coming up to Amazon are the new Grove connector units. They are 100% compatible and they now include the Grove Adaptor to Male Headers cable.

      Best,

      SDL

    I previously contacted you about a switch bounce problem with my rain tipper. I had another problem of rain indication when there was no rain. After months of experimentation I found that the phantom rain was being caused by USB power noise. It appeared on every computer I tried, but was minimal on a laptop. Searching the internet I found this post: http://andybrown.me.uk/2015/07/24/usb-filtering/. I modified a USB adapter for my Pi 3 using his circuit. For a few cents worth of parts the phantom rain went away. Now I was able to see a reliable 3 triggers per tip which I corrected in software. This noise was probably affecting wind speed as well. Now I can calibrate my rain gauge against a tube gauge and recalibrate my anemometer.

    My station software is written in Python and runs on Windows, Linux and Mac. It post a local web page, ftps a web page to a web server, and telnets the data to the National Weather Service via the Citizens Weather Observer Program. With the addition of an AM2302 for humidity, the quality control analysis of my data by CWOP has shown it to be accurate and reliable except for rainfall.

      Excellent find. I have repeated this in the forums for others.

    I just set up my SmartPlantPi kit (that I got as a KickStarter reward) by following the ‘AssemblyAndUsageManual 1.0’ and now am looking for the Advanced Manual to hook it up to Freeboard. Where can I find it?
    Kind regards, Ted

      It’s not quite out yet. We are hoping to publish it on June 1st. Stay tuned. If you want to do it yourself, you can really do it by following the SunIOT tutorial on switchdoc.com. It will be very similar to that flow. 🙂
