How to Set Up a Solar Powered Webcam Server Using NanosG20 Running Debian


Introduction: How to Set Up a Solar Powered Webcam Server Using NanosG20 Running Debian

About: I am a researcher working on development of optical atomic clocks. Electronics is my hobby since childhood when my uncle was bringing me old phones to play and take apart.

NanosG20 is one of the most energy efficient Linux boards wtth a 400 MHz ARM processor, consuming <1 W when running and 25 mA from 5 V in power-down mode.With a webacm and WiFi stick power consumption is 2.5 W.
This is the right board if you need a low-power solution like when running on solar energy.

I have set up NanosG20 running on solar cell and 12V 8 Ah hattery in my garden house that is 15 m away from WiFi access point uploading pictures to the Internet.
A few days it was runing running on a Huawei GSM modem sending pictures from a city skatepark.

NanosG20 runs reliably. All Debian things more or less work. Board costs 99 EUR.  Howewer for home use would reccomend to set up webcam on an OpenWRT router as every home needs a router.

The notes below contain the code that will help you to set up NanosG20.

    Thank you for sharing this great schematic! I was wondering if you could configure this to use a Verizon Aircard to upload images rather than WiFi, maybe 5 images or so per day. Do you think this could be done? Thanks!

    I tried to attach Huavei modem. And after some hours of trying could get it working. Here is description
    However do not know about compatibility with Verizon.

    Now I would probably use WR703N. as it already has a built in functionality for GSM modems ppp. Would attach a USB hub and have on one port webcam and on antother GSM modem. I have tried only webcam, but not GSM modem.

    Thank you for the recommendation!

    Details on the hardware construction would be nice, or even a link to another instructable that you may have used.

    I have made instructable concerning solar part here

    In NanosG20 the only thing what was modified was to connect a 1Meg potentiometer on the analog input pin to increase the acceptable voltage range from 3.3 to 20 V. Analog input is used to monitor battery voltage that is showed in a dataplot online.
