    I’d like to hear your thoughts on solar for roadways in general and specifically the old Gandy Bridge. It’s been proposed, but in the backwoods that Tampa is, will probably remain in ‘committee’ forever. What does price need to drop to? Low enough for Teco to buy all the companies interest in Florida?

    There is a company near here doing solar roadways. (http://www.solarroadways.com).

    Cool concept, but there is a lot of testing to be done. How long will they really last? How much will they really cost? It’s a long process to get to those answers, but they are making progress.

    Is Amazon the only way to purchase things from SwitchDoc? I don’t do Amazon any more as I had a bad experience in the past with their lack of customer support of the sale (referring me to a third party instead of addressing the issue themselves).

    Just know that I owe you a drink or dinner; you saved my butt after literally three days of doing nothing but working with ble in linux. If I had the budget i’d hire you; sadly, I’ve got a “small project contractors” budget. If you offer consulting or per hour pricing, please let me know.

      Arlow,

      Thank you for the compliment! Made my day. I’m pretty much booked up right now for consulting (and I do per hour and per project), but let me know if you have some questions.

    Hi John,

    I’m going to get my “Really Useful Breakout” package on Tuesday and am very excited to get started. Two questions:

    1. Is the “Comes with an iPhone / iPad based Control Panel App ($2 on App Store – SunAirPlusPiConnect /SunAirPlusArduinoConnect)” still going to happen? The PiConnect app is 12 bucks at this time.

    2. I have a 12 volt solar panel. Do i need to get a step down buck converter to 6 v before using it with the SunAirPlus?

    Thanks for the info!

      Hi Mark,

      Glad you are getting your package soon. We haven’t shipped anything from the “Really Really Useful Breakout Boards Kickstarter yet – it is still open until next week” but I assume you mean SunAirPlus is arriving on Tuesday. 🙂

      1) The SunAirPlusPi/Arduino Connect is still in the development chain. The delay is not MiloCreek, it is us in getting them all of the information. We will be shipping in April, a week or two through the Appstore and it should be there. We will keep you posted on our Blog.

      2) Yes, you can’t supply more than about 6.5V to SunAir or SunAirPlus. Step it down and it will work fine. It will be interesting to see how the power curve changes with a Buck Converter in the Solar Panel path. Good think you have SunAirPlus and you can look at all that very cool data.

    Thanks John. I should have read the email from Kickstarter more closely! (You’re getting the prototypes next Tuesday not shipping).

    Just bought one of SunAirPlus boards from Amazon. Looks great, I’ll be gathering the rest of the parts I need and press it into service in a month or so. I can send photos when done if you’d like.

    Can you design and sell a USB dongle that I uses with the RaspPi, ala a serial interface or something (ease of driver use), with a postive and negative connector for a 24/12volt, 6volt battery, that would output a voltage. Pretty simple, but it’s doesn’t exists except for much higher cost $70 on ebay with a wider range for voltages.

    There lots of people who need 12/24 volt powered gear along with power for the RaspPi, lots of dc-dc step-down gear from 12volts on ebay, I just need a clean, simple, lower cost, lower power USB dongle to monitor the 12volt power, versus building a breadboard circuit for each one.
    I thought about doing a kickstarter project for this, but since you have already done that, this may a good next project?

      Hi Dewey,

      I’m a bit confused.

      Are you looking for something to monitor 12-24 Volt current and Voltage from the Raspberry Pi? If so, then our second kickstarter ( https://www.kickstarter.com/projects/sunair/really-useful-breakout-boards-for-raspberry-pi-ard ), recently successfully concluded produced a breakout board that can measure from 0 to 26V common-mode and -26CV to 26V in differential mode. Currents and voltages.

      It’s not a USB Dongle (which is a good idea by the way), but it is out and it works not he Raspberry Pi I2C bus. Lookup INA3221 on Switchdoc.com to see the info. The board has been released to production and will be available for sale next week or so.

      Best,

      John

    Hey guys! Could you take a look at this page: http://www.switchdoc.com/weatherpiarduino-bare-board/
    Use an ipad and see the page jumping up and down due to a malfunctioning photo…
    Thanks!

      Just went to that page and everything looks fine on an iPad. What version of iOS are you using and what photo is behaving badly?

    I have just received my SunAir Plus, and actually have the WeatherPiArduino targeted to arrive in 2 days.
    For both it notes you have the arrangements for the SunAirPlusArduinoConnect and such from Milocreek ready back in April?
    I cant seem to find these apps or now to get them for the discounted rate.
    Can you please help point me to the correct place?

      The discounted RasPiConnect Apps aren’t available yet. Not MiloCreek’s problem, we just haven’t shipped the changes yet. Hopefully before August.

        If my project reaches the point its ready for the apps before then, am i safe to assume the full priced version will work just as well? or is the app they are doing special for your product(s)

        • SwitchDoc Labs Author
          2 years ago · Reply

          Absolutely. The special app is just a limited version of the full priced app. It is locked to one page and one configuration file. You can do all features with the full priced RasPiConnect milo creek.com App.

    I have a 50W solar panel with a marine wet battery (charge controller between them). I would like to use something like SunAir, but more current than it can handle. Is there something like this?
    Thanks, Vince

    • SwitchDoc Labs Author

      Vince,

      Yes that is more current than SunAir can handle. You can get a commercial unit and then use our INA3221 3 channel current sensor to gather data.

    RE: USB PowerControl

    So are the USB data lines also supported on the USB PowerControl or is this device strictly for supporting power control?

    • SwitchDoc Labs Author
      2 years ago · Reply

      The Data lines (D+, D-) are passed through. Only the USB +V Power line is switched.

    Hey there,

    I am a CS student doing my senior project this semester. The idea of my senior project is to build a personal weather station that collects weather data and sends it to a dedicated mobile app over an API(which I will be coding). However, since I am CS I can’t have a mechanical side involved with my senior project so I would like to have an already built sensor stations that I can use. My target is to write code to drive the sensors(optional) and be able to access/store weather data in a database server and support the mobile app with it.
    Or I can have the sensors code written for me but I still need to have some sort of interface to the data(access it programmatically) and deliver the data to the mobile app
    I looked at the GroveWeatherPi and the WeatherPi Solar Powered Raspberry Pi Project but I couldn’t determine which is a better fit if any?
    Can you please help me on this

    Thanks a lot
    Mohamad

      Mohamad,

      GroveWeatherPi is the better choice. It is a newer design and has a full suite of sensors. You will be able to modify the software in Python to do whatever you want. It requires no soldering so it is easy to put together.

        Thank you very much for your quick respond
        I will be purchasing it immediately!
        Can I access the data collected via an API written in C#(ASP.NET) or Python that the mobile app can consume?

        Also can you direct me to a link where I can purchase the GroveWeatherPi? does it all come in one package?

        Thanks a lot again

    Dear receiver,

    Thanks a lot for your previous advise!
    I want to purchase the GroveWeatherPi but I am kind of confused about what parts should I be purchasing
    I found the GROVEWEATHERPI PRODUCT BUNDLE at: http://store.switchdoc.com/groveweatherpi-product-bundle/
    is this all what I need? the content information is kind of saddle. It doesn’t tell me if there is a Raspberry PI included in the bundle or not! and if there is one what version? is it the Zero or A+?
    Can I access the data collected(or the MySQL database) via an API written(by me) in C#(ASP.NET) or Python that the mobile app can consume?

    Also can you direct me to a link where I can purchase the GroveWeatherPi? does it all come in one package?

    I am sorry for all these questions but I am trying to finalize the purchase but everything should go through my school adviser and all the purchasing should occur up in front and in under one purchase.
    My apologies again
    Thanks a lot for your help
    Mohamad
