We always like to call out a commercial success stemming from projects that got their start on Hackaday.io, and so we’re proud to announce the release of MAKE: Calculus by Joan Horvath and Rich Cameron, a book that takes a decidedly different approach to teaching calculus than traditional courses. Geared to makers and hackers, who generally tend to have a visual style of learning, the book makes heavy use of 3D-printed models to illustrate the relationships between functions. The project started five years ago as a 2017 Hackaday Prize entry, and resulted in a talk at the 2019 Supercon. Their book is now available for preorder, and might be a great way to reacquaint themselves with calc, or perhaps even to learn it for the first time. Continue reading “Hackaday Links: July 10, 2022”
Location, location, location — what’s critical to real estate is also critical to eclipse watching, and without sounding too boastful, those of us atop South Menan Butte, an extinct volcano in southeast Idaho, absolutely nailed it. Not only did we have perfect weather, we had an excellent camping experience, great food, a magnificent natural setting, and a perch 800 feet above a vast plain stretching endlessly to the east and west. Everything was set up for a perfect eclipse experience, and we were not disappointed.
Golf is an expensive obsession for some, with course fees on the most memorable and challenging courses running into the hundreds of dollars a game and beyond. If playing one of the most unusual holes in golf is simply beyond your means, there’s no need to fret – just do what [TVMiller] did and build a miniature mobile replica of the famous Coeur d’Alene Resort Floating 14th hole.
The Floating 14th is pretty spectacular as far as golf holes go. With a green located on an island about a hundred yards offshore of beautiful Lake Coeur d’Alene in northern Idaho, there’s little room for error – after all, it’s surrounded by a 49 square mile water trap. [TVMiller]’s replica green recreates the target quite accurately, although we doubt the Jolly Wrencher flag is regulation for championship play. But the best part is the motorized platform and smartphone app that can be used to send the mini green out as far as you feel like practicing. Sure, it could be a tad more realistic if the replica green actually floated, but asphalt fairways are a little easier to come by than Olympic-sized swimming pools.
A fun, tongue-in-cheek project, and we really enjoyed the faux TV coverage of the 2015 Hackaday Golf Championship in the video below. If real golf isn’t your thing, you might want to build a table-top golf course, or play a round of mini golf with a ball-incinerating Portal themed hole.
