Guy MarsdenGreetings!
I live with my wife Rebekah in rural Maine where I work out of my solar powered and heated barn workshop.
  
I started this web site in 1997 and add to it when I have new things to share, it now includes well over 210 pages.  I update the site frequently, so there's often something new to see.  Check below for the latest updates.

In recent years I have come to define myself as a "creator".  This concept encompasses the many media and technologies with which I work, all require the idea of creating or designing something new.  This is what gets me up every morning and keeps me going every day.  Creating.

Since 2001
I have made a big commitment to live as sustainably as possible and my web site documents all my efforts to reduce the carbon footprint of our lifestyle.  The main reason I share this information is to help others who are equally committed to saving our planet from the impending climate disaster that global warming presents.

BUILDING PROTOTYPES
Since the mid 1980's I have worked with inventors and small companies to build custom electronic prototypes of all kinds.

Here you will find my background, examples, and a detailed example of my design process.
piano artwork ENGINEERING FOR ARTISTS
I work with artists to design electronic controls for their light, kinetic, video, audio and multi-media work. 

Here you will find an extensive gallery documenting many projects large and small.


My wife and I are committed to living sustainably, here are blogs and information about all the things we do to live lightly on the planet.
LIVING SUSTAINABLY
On this page I list all the things that we do to live sustainably from owning 2 hybrid vehicles to simple no-cost things like composting and turning down the water heater.

By modeling the world we want to see maybe others will join us in living lightly on the planet without compromising a comfortable lifestyle.
SOLAR POWER SYSTEM
Blog that documents the process of financing, designing, purchasing and installing a 3.6kW solar power system myself in the summer of 2009.  The system consists of 21 175 Watt solar panels with Enphase M190 inverters behind each panel that convert solar power directly to 240 Volts AC.  By installing it myself, I saved about $9000.
SOLAR HEATING FOR MY WORKSHOP
In 2001 I designed and built a solar augmented heating system for the radiant floor in my workshop.  The backup is propane, and I later added a wood stove to reduce the propane consumption.  This blog documents the initial construction and the continuing improvements and lessons learned.
HEAT RECOVERY VENTILATION SYSTEM IN MY WORKSHOP
In October 2008 I installed a heat recovery ventilator in my workshop because the building is so well sealed in the winter that I was concerned about indoor air quality.  This inexpensive system replaces the air and recovers 86% of the heat as it exits the building.
"Many hands make light work" SOLAR DOMESTIC WATER
In July 2006 I installed a solar domestic water heating system with the help of my friends. 

This blog documents the installation of a solar system that was purchased as a complete off-the-shelf kit, although I made a few modifications.
SOLAR LAWN MOWER
In July 2005 I converted a gas lawn mower by replacing the engine with a 12 Volt electric motor run from a battery that charges from solar electric panels on my shed roof.

In my blog I have detailed every step of the process so that others can build their own.
THERMAL WINDOWS
In 2008 I came up with a design for an interior thermal storm window that can be made easily and inexpensively.  If placed in all the windows of a home these simple frames of double pane shrink film can save hundreds of dollars in heating bills in colder climates.

Complete instructions with detailed pictures show you how to build these simple energy savers.

FURNITURE
My furnishings are all based on a theme of thin vertical staves as a primary visual/structural element.  I work primarily in native woods; maple, cherry, walnut and some exotics.

I have exhibited in craft shows and galleries across the country since 1997.  Here you will find a catalog of my designs, information about how I work and where to find my work.
CANOE
In July 2007 I decided that I needed a small, light canoe that I could use to paddle around Maine's waterways.

This detailed blog shows the construction of my 14 foot stitched lapstrake canoe, made from plans in a book.  Made from 4mm marine plywood it weighs less than 47lbs.

ART TEC Solar - DTC-AT controller SOLAR DIFFERENTIAL TEMPERATURE CONTROLLERS
Designed to control solar powered pumps in closed loop solar heating systems, these simple and affordable controllers will improve performance by preventing a solar powered pump from running if the collectors become cooler than the storage tank.
MAGNETIC LEVITATION KIT
This simple electronic kit uses magnetic levitation to suspend small objects up to about 1/2 ounce (15 Grams) or so in mid air.  This is an ideal Science Project for ages 12 and up!

Defy gravity!  Enhance levity!

Assembled and tested versions as well as parts kits with detailed instructions from $38.00

"Entropy 3" artwork MY ELECTRONIC ARTWORKS
I began making electronic artworks in the mid 1980's.  My work has exhibited in museums and galleries throughout the country and is in several private collections.

My early work focused on a series of "Digital Numeric Relevators" that satirized our implicit trust in electronically represented numbers. 

My current work (left) focuses on kinetic color fields that mutate randomly, creating hypnotic effects.

In the
media
IN THE MEDIA
Over the years I have appeared in the media in a variety of ways, and also have authored numerous articles on art, technology and solar issues.
WEB CAMS
I have 2 web cameras that show images of my workshop and solar panels as seen from the dining room window of our house, and inside my workshop.  You may catch a glimpse of me at work - or mowing the lawn with my solar powered mower!
TIME LAPSE MOVIE
I made a time lapse movie of our house by taking 1 frame per day at noon from a web cam in my office window.  And every so often I take a panoramic view of our property so that folks from away can share the beauty of our surroundings.
TWITTER FEEDS
When I have any significant news I Tweet about it - often I'll post a link to a new page on my on my site.  This is a good way to stay up to date on my on-going projects.

A variety of links representing my diverse interests
