SunAir Solar Power Controller for Raspberry Pi and Arduino

Ever wanted to build your own Solar Powered Raspberry Pi or Arduino system?   SunAir and SunAirPlus are 3rd Generation Solar Charging and Sun Tracking Boards designed by Dr. John C. Shovic at SwitchDoc Labs. You can use this board to power your projects and add a servo or stepper motor to allow it to track the sun using photoresistors to generate even more power! It incorporates a number of outstanding feat ...

Solar-Oriented, Arduino-Powered Clock

This is a clock designed to keep accurate time (independent of atomic or GPS), display local sunrise, sunset and solar noon, and also adjust itself for daylight savings time. I wanted the clock to be easy to use and be flexible. The setting functions are menu-driven, you set each parameter one digit at a time (with live data validation) and you can abandon changes if you want. You can have 12 or 24-hour tim ...

Print-On Polymer Multiplies Solar Output

PORTLAND, Ore. -- Scientists have demonstrated a doubling of the number of electrons produced by carbon-based photovoltaic polymer potentially doubling the efficiency of any solar cell. The process called "singlet fission" produces "identical twin" electrons from a single photon, instead of the normal one, dramatically boosting the theoretical maximum output of solar cells. Instead of loosing energy to heat ...

Solar powered wireless Arduino based Geiger counter porject.

Hello, I have plans to build myself a solar powered wireless Geiger counter using a RH Electronics Arduino IDE Geiger counter connected via a serial connection through a logic level converter to a 3.3V ATmega328P-AU Pro MCU with an ESP8266 serial WiFi tranceiver to send the readings from the Geiger counter to radmon.org.I intend to connect the hardware together something like this, #include <SPI.h> #i ...

Solar Panel Battery Charge Controller Using Arduino

This is an updated version of Solar Panel Charge Controller Using Arduino. Solar Panel Battery Charge Controller Using Arduino Pictures of Power box and Arduino solar charge regulator: Charge Regulator with Power Box Connections to Regulator Inside the Box The output voltage of the ACS712 is 2.5V with no input while the spec sheet specifies 66 to 185 mV/A output sensitivity. That's a broad range and given t ...

Arduino Solar Radio

Solar charging, via the panel on the back. * 12 position switch to select channel number * Seek up / seek down controls and 'store' button * RDS display of call sign * Frequency display * Battery voltage display * Solar charging current display The software still needs a bit of attention. Its fine if the signal is good and RDS comes in quickly, but if not, then adjusting the volume or changing channel takes ...

Solar Powered LED/Ultracapacitor Arduino Regulated Light

This instructable primarily shows how to control the charging voltage from a solar panel to an energy storage device (capacitors in this case). I showed how to construct the light previously http://www.instructables.com/id/Human-Powered-Light-from-my-book-Doable-Renewab/ Step 1: This solar panel can produce up to 18 volts, but my capacitor bank should never receive more than 15 volts.  I want to stop chargi ...

Arduino Solar Tracking Robot

This is a simple solar tracker which automatically orients itself towards the sun or any bright source of light like the sun .If you place solar panels on this robot it can increase their productivity by 90 to 95 %. At first creating a solar tracking robot may sound complicated but it quite quickly becomes clear. As the title suggests it runs on the arduino board .This is a fun to do and low cost project. T ...

Lithium Battery Solar USB – iPhone – Arduino Charger

One of the most fun and useful projects on instructables is to create your very own solar USB/ iPhone charger. They're not overly difficult to make, nor are the parts overly expensive or hard to find. For the most part they do a rather good job of charging up small gadgets. Mostly. The big flaw in the DIY solar charger world are the batteries. Nearly all the designs on instructables (including all of my des ...
