Information and free software on projects that I, David LaBrecque, have worked on both in and out of the Chemistry Department at the University of Maine. Click on links for more information or to download software.
Ring Diffraction Spectrometers
Introduction to Ring Spectrometers. See Download page for free design software and pdf of Power Point presentation given at the University of Maine.
Star Doors Novels
Science fiction novels that couple the strangeness of physics (quantum entanglement) with the bizarre extremist politics of today, and tries to make sense of it all. Where is humanity going? Where do we want to go? Two fascinating UMaine college students try to find answers in this entertaining adventure through time and space.
Physics of Learning
Do Students Obey the Laws of Physics?
Extending a physics analogy to teaching and learning creates a rich set of terms and relationships that are already familiar to scientists. This paper defines those terms, suggests methods for quantifying those terms and thus provides teachers with a method for optimizing student learning. The author’s role in developing a 1000 student per year, computer networked chemistry lab provides a unique opportunity to analyze these terms and relationships. Get PDF from download page.
My Geothermal Heat Pump
A ground loop geothermal heat pump I installed at my home which provides both low cost heating and air conditioning.
My Grid Tied Solar Array
Chart the falling prices of photovoltaics and it becomes obvious that solar panels will help solve our problems with energy and climate change. So I added grid-tied solar panels to my home and now can enjoy watching the electric company's meter spinning backward on sunny days.
Home-Built Skate Sharpener
I try to play hockey twice a week year round and I like sharp skates. Rather than pay $5 every few weeks to get the edges I want, I opted to build my own skate sharpener. I've used this $150 setup for about twenty years and saved over $1700!
SnowBear Plow Fix
I like my SnowBear personal plow. It beats snowblowing my 300 foot driveway and definitely beats paying someone who may or may not show up to plow my driveway. Unfortunately the plow puts a high load on my Ford Escape's front end 2" hitch which can bend the hitch downward. This unusual fix is surprisingly strong.
EBike: All Electric Bicycle, No Pedals!
Powerful electric bicycle with 2 electric hub motors gets 3 miles a penny.
400 NMR donated to University
Hundreds called about this free $100,000 NMR when it was posted one evening in an NMR newsgroup. I just happened to be first to realize its value and say yes, we definitely want it. Its now an essential University research tool.
Publications and Patent
I've authored/coauthored papers on Dielectric Properties of Snow, Using Pulsars to Observe Interstellar Matter, Mass Spectroscopy, A Flexible Wing Energy System, a US Patent on Circular Diffraction Spectrometers.
General Chemistry Web Page Analysis
UMaine students can now collect data on advanced scientific instrumentation and analyse their data on their smart phones, tablets's or laptops. This is part of the innovative ICN project initiated and coordinated by Prof. Mitchell Bruce, Prof. Francois Amar and Robert Kirk.
