BOOKS | Dylan Evans
Saved by uncleflo on February 12th, 2022.
Imagine you have survived an apocalypse. Civilization as you knew it is no more. What will life be like and how will you cope? In 2006, Dylan Evans set out to answer these questions. He left his job in a high-tech robotics lab, moved to the Scottish Highlands and founded a community called The Utopia Experiment. In this book he tells his own extraordinary story: his frenzied early enthusiasm for this unusual project, the many challenges of post-apocalyptic living, his descent into madness and his gradual recovery. There is a special kind of intelligence for dealing with risk and uncertainty. It doesn’t correlate with IQ and most psychologists fail to spot it because it is found in a disparate group of people such as weather forecasters, professional gamblers and hedge-fund managers. This book shows just how important risk intelligence is.

Arvel Gentry | North Sails
Saved by uncleflo on April 10th, 2021.
In the first edition of the Art and Science of Sails, written by Tom Whidden, president of North Sails Group, LLC, and Michael Levitt, and published by St. Martin’s Press, the authors used Arvel Gentry’s now famous Bathtub Experiment to demonstrate the existence of Circulation, or a second force, that operates around an airfoil, like a sail, wing, or keel etc. Big picture: it’s the combined effort of these two forces that makes the wind speed up on the leeward side — and thus show low pressure — and slow down on the windward side of a sail — high pressure. Gentry was the Boeing engineer who first taught sailors aerodynamics. These diagrams first appeared in Gentry’s Sail magazine articles. In the Revised Edition, the authors used computer testing to show where the wind speeds up around a sail plan and where it slows down. And why and by how much? Nevertheless, Gentry’s experiment is the standard — still popular on the web — and it was left it out of the Revised Edition with trepidation, but we linked in the book to this web page.

The ultimate antifouling group test - Motor Boat & Yachting
Saved by uncleflo on July 24th, 2019.
Our antifouling paint test threw up some interesting results. At first glance the boards show a range of different results, but only when you investigate the product and why it performed how it did do you fully understand what has happened.
Firstly it shows that professional application paints seem to perform marginally better. The higher toxicity of the paint is deemed too risky for the public to handle, so perhaps that’s why it’s also more effective.
Rather more surprising is that, contrary to expectations, many of the paints performed better in the Mediterranean than in the UK, although as the variations in our UK results proved, that may not apply to other areas of the Med.
The muddy waters of the East Coast proved the most challenging with all the paints showing plenty of slime and the occasional patch of weed.
However, the big surprise for us was the relative success of the silicone paints in a static test that would usually have favoured soft or copolymer copper-based antifoulings.
When choosing a paint, it’s important to think about how much you’ll be using your boat, as some of the hard paints will perform so much better with regular usage, while if you only plan on pottering up a river occasionally, you might be better off by going for a soft self-eroding paint.
Armed with the results of this test, you should be able to make a more informed decision on what paint to use this season, even if you’re not bold enough to try the silicone alternative.

ABB Robotics - Milling Sculpture in Natural Stone
Saved by uncleflo on November 29th, 2018.
In the last few years Robot integrator T&D in collaboration with a leading supplier of natural stone, Marmi e Graniti d'Italia (MGI), has applied its technology and innovation for applications in the stone industry. One of the latest frontiers in the field is definitely the interaction between ABB robots and natural stone. Using the creation of a replica of artist Amedeo Modigliani's infamous "HEAD" sculpture in white granite, T&D explored the application of a robotic milling system to evaluate whether industrial robots are capable of the demands and challenges that processing stone requires. The results of the experiment surpassed all expectations offering a quality of cut comparable to CNC machinery. The possibility of perfecting the approach, integrating milling and polishing, is currently being explored in collaboration with ABB integrator T&D Robotics.

How To Turn Styrofoam, Into Solid Aluminum
Saved by uncleflo on July 18th, 2016.
The gun is solid aluminum, made from melted down soda cans. I spent over 100 hours of time, and 7 styrofoam prototypes to make this video. About a third of the time was spent filing and sanding the gun. Each time I poured a casting for the gun, the trigger guard wouldn’t complete all the way through, so I kept making new styrofoam guns, modifying the designs slightly until it worked. Once I got a fairly clean casting, I put 2 days into filing down rough points, and sanding them smooth. The gun could use a little more work, and it’s not perfect, but this experiment was mainly a proof of concept that nearly anything you can imagine can be made fairly easily with the “lost foam casting” technique. Overall, I really am happy with the gun though! It weighs 556 grams, and is really quite smooth to feel. For future projects, I plan to work more with green sand casting. I believe it will leave a nicer finish overall and won’t require as many prototypes to get it right :) Instead of foam, wood plugs can be used to make the molds, or even real weapons for that matter.

Google Analytics Content Experiments - A Guide To Website Testing | Testing & Usability
Saved by uncleflo on April 4th, 2015.
In this article I discuss Content Experiments, a tool that can be used to create A/B tests from inside Google Analytics. This tool has several advantages over the old Google Website Optimizer, especially if you are just starting the website testing journey. Content Experiments provide a quick way to test your main pages (landing pages, homepage, category pages) and it requires very few code implementations.

C = 4*m + 3*v + 2*(i - f) - 2*a. Anxiety is one of the key elements in the MarketingExperiments Conversion Heuristic. In our Landing Page Optimization Online Course, anxiety is defined as “a psychological concern stimulated by a given element in the sales or sign-up process.” Essentially, anxiety is a negative element on your landing page that reduces the likelihood that a potential customer will take a desired action. It’s no big surprise that experiments with our Research Partners have found third-party privacy and security seals help reduce customer anxiety and improve conversion. So, let’s take a look at two types of seals that can help you reduce customer anxiety.

DARPA: You didn't think we could make a Mach 6 spaceplane, so let us have this MACH TEN job • The Register
Saved by uncleflo on June 3rd, 2014.
A Mach 10 plane capable of rapid turnaround between missions will need to be pretty tough to resist the heat generated as it bores through the atmosphere at hypersonic speed. In DARPA's view this will be pretty much as bad as the frying the space shuttle used to suffer and the X-37B still does. The XS-1 will need "low-maintenance thermal protection systems that provide protection from temperatures and heating rates ranging from orbital vacuum to atmospheric re-entry".

LED Cube Matrix Driver
Saved by uncleflo on February 8th, 2014.
Do a search on YouTube and you'll turn up literally dozens of video clips of LED cubes, small 3x3x3 cubes, bi-colour, RGB and mono cubes, amazing 16 x 16 x 16 RGB cubes. However, very few show you how to make one and provide the firmware. The cube described on this page uses a 5 x 5 x 5 matrix of single colour LEDs. This is a good size to experiment with as the number of LEDs required at 125 keeps the cost down, doesn't take too long to assemble and just fits onto a eurocard sized PCB. The power requirement is under 1 amp and the use of just one colour keeps both the hardware construction and control software fairly simple.
