SCC2 10 Amp Solar Charge Controller - The SCC2 is a solar charge
controller, its function is to regulate the power flowing from a
photovoltaic panel into a rechargeable battery. It features easy setup with
one potentiometer for the float voltage adjustment, an equalize function for
periodic overcharging, and automatic temperature compensation for better
charging over a range of temperatures..... [G. Forrest Cook] |

SCC3 - 12 Volt 20 Amp Solar Charge Controller - The SCC3 is a
solar charge controller, its function is to regulate the power flowing from
a photovoltaic panel into a rechargeable battery. It features easy setup
with one potentiometer for the float voltage adjustment, an equalize
function for periodic overcharging, and automatic temperature
compensation.... [G. Forrest Cook] |

Self Powered Solar Box Furnace - This project involves the construction of a
self contained solar box furnace (Photo 1). I assembled the prototype with materials
that I had laying around my workshop. It is suitable for heating up a small room or a
detached shed. I use the furnace to warm up my garage, it takes the chill out of a
fairly large space when the weather is cold, but sunny. It is possible to scale this
project up to any size, a larger version, or a set of them, could be used to add a lot
of supplemental heat a house.... [G. Forrest Cook] |

Self-Powered Solar Data Logger - My project is a self-powered solar data
logger. Put out in the sunlight, it will measure the light level and log this to
memory to be later downloaded to a computer. The system is powered by a small solar
panel and battery….... |

Sensor Electronic Tracker with H-Bridge Drive - I decided to make a
commercial surface mount PC board using the LED2 sensor concept. It is quite sensitive
and can track to a few degrees of accuracy in bright sunlight. If a blocking shadow
is used the accuracy is better then 1/4 degree, that's about as good as you can get
with an active feedback sensor. The board is a tiny .7"x1.4".... [The site is owned by

Sensor Electronic Tracker with Simple Solar Charge Controller - The "LED3"
light sensor works very well. It is sensitive, accurate, and cheap. A couple of years
ago I had devised a simple solar charge controller I called "Shunt 2". I thought it
would be a good idea to combine them into a single PC board called the LED4.... [The

Seven Component Regulated LED Lamp - This is a minimal parts lamp made with
four white LEDs. It features regulated light output from 10V to around 20V and works
well as a flashlight. [G. Forrest Cook] |

SIMD1 V0 - Nocturnal-Controlled Solar Engine: The original SIMD1, the V0
does its magic with just a resistor and a Germanium diode. (added 11/05)
|
|
SIMD1 V1 - Nocturnal-Controlled Solar Engine: The V1 is just like the V0,
but with polarities reversed. (added 11/05) |
|
SIMD1 V2 - Nocturnal-Controlled Solar Engine: The V2 has two flavors,
essentially modifications of the V0 and V1, but with a transistor and resistor
replacing the diode. This variant turns on earlier (i.e., before it's so dark)
and "cleaner" than the V0 and V1. (added 11/05) |
|
SIMD1 V3 - Nocturnal-Controlled Solar Engine: The V3 is very similar to the
NPN flavor of the V2, but with the addition of a FET on the output line. This
makes life easier for its attached load. (added 11/05) |
|
SIMD1/Solar Regulator - Nocturnal-Controlled Solar Engine: The SIMD1 / Solar
Regulator supplies a constant 2V after triggering and permits driving LEDs with
constant brightness without the need for current limiting resistors. (added
