Last week, I forgot to include a link to the oscillating multi-tool tips video I included. Thanks to those of you who kindly pointed out the omission. In the future, if this happens, you can always go to the channel I mention, search on the subject, and find the video. My apologies for the hiccup.
Tips Busters: Amazingly Stupid Tape Tricks
Months back, I proposed the idea of doing a “Tips Busters” section where I deputize readers to try out a tip, any tip they see that appears too good to be true, to determine whether it works, doesn’t work, sorta works. I’m still hoping to put such a series together. If you want to bust a tip or have a tip to bust, message me. In the meantime, I’m going to start running pieces from others who are testing and evaluating tips. On this episode of Stumpy Nubs, James looks at a number of dubious (at best) painter’s tape “hacks” as found on YouTube. There are many such tips. As James points out, lots of them are just plain silly.
Understanding Tolerances for 3D Design and Printing
Via Maker Update comes this gem of a video on Practical Alchemy about understanding parts tolerances when designing in Fusion 360 (and other CAD programs) and how to ensure that your 3D designed parts will properly fit when sent to a 3D printer. They also show you how to create a 3D printed “Fit Guide” to better understand and accommodate tolerances for your particular printer.
A User’s Guide to H-Bridge Motor Drivers
Anyone with even a casual familiarity with hobby electronics is likely familiar with H-bridge motor drivers. So named for the H-like configuration of the circuit schematic, with its 4 switching elements, these drivers allow you to control DC motors for speed and moving forwards, backwards, left, and right. In this DroneBot Workshop, they look at a number of popular H-bridge drivers (e.g. L298N, DRV8871, and the MX1508) and the types of DC motors they can control. At over 1-hour, this is a useful crash course in understanding and using this common drive train controller.
Animations of 75 Different Knots
Via the Tools for Possibilities newsletter comes this amazingly useful resource. Knot-tying is a fundamental maker skill. But learning to tie them from a text, or looking at still images, can make them seem unnecessarily confusing and complicated. I don’t know about you, but seeing these knot animations immediately makes me want to grab a rope and go to lashing school.
Maker Slang
Slang, jargon, and technical terms for the many realms of making things.
Surface profile – The 3-dimensional tolerance zone around the surface of an object, often one that’s a complex curve or shape. This profile requires that every point along the surface lies within a specified tolerance range.
Slush casting – A form of casting where material is “slushed around” inside of a mold, creating a thin layer on the outer walls of the casting. This technique is most often used to create a lightweight, hollow castings. It can also be done as the first pour in a highly-detailed mold, with a second pour finishing a solid cast.
The Rule of Cool – In making anything from realms of the imagination (e.g. sci-fi, fantasy, other fiction), the overriding of realism, the laws of physics, and practicality in the service of sheer cool factor.
Shop Talk
In response to my piece on toilet floats and valve reseating tools, I got an interesting message from a reader. He was taken aback by the fact that doing this sort of basic household plumbing was even a question for me. He assumed that any maker/handyperson would do this type of maintenance/repair work without even thinking about it. This led him to ask: “Is there anything you look at and think: ‘I cannot fix THAT!’ I’ve never once thought that. Am I in the majority or minority?”
My situation might be somewhat unique in this regard. I have severe spinal arthritis. So, many maintenance, repair, and DIY projects are outside my reach. Even to replace the float tank, I couldn’t reach down and shut off the very frozen water intake valve on the toilet. I had to get a friend to come over and do that for me.
But even for the more physically able, I’m sure there are preferences. I know plenty of people who loathe house painting, and others who would never think about doing electrical work. And I know plenty of electronics nerds who build robots, microcontroller projects, and all sorts of other high-tech makery who wouldn’t think about doing traditional shopcraft (woodworking, metalwork, etc). And vice versa.
Different strokes for different folks. And so on and so on and scooby dooby dooby.

Cool tools really work.
A cool tool can be any book, gadget, software, video, map, hardware, material, or website that is tried and true. All reviews on this site are written by readers who have actually used the tool and others like it. Items can be either old or new as long as they are wonderful. We post things we like and ignore the rest. Suggestions for tools much better than what is recommended here are always wanted.
Simply as advertised. Rows and rows of diverse things neatly organized. This process is often called knolling. The applied organizing logic varies: it can be by size, by color, by age; in rows, in grids, in fitted mosaics. The effect is always hypnotic. Seemingly meaningless collections gain intelligence and order which focuses attention on the parts. The book ranges wide and far in the type of things that are inspected. You will soon knoll your own. – Kevin Kelly
SHARKS – TASCHEN’S HUGE, STUNNING NEW BOOK ABOUT OUR OCEAN’S MAJESTIC, ENDANGERED PREDATORS
Sharks. Face-to-Face With the Ocean’s Endangered Predator by Michael Muller Taschen 2016, 334 pages, 11.5 x 15 x 1.5 inches
Sharks. The word alone conjures images of grey and white shadows, dorsal fins slicing through the water, row after row of fierce, terrifying, teeth. And we love them for it. Since Jaws first made us all afraid to go into the water, sharks have become our favorite bad guys. We paint them as the apex predators, devouring everything that dares enter their territory, including we frail, defenseless humans. And then we anthropomorphize them into relentless, driven killers, intent on feasting upon every last one of us. While this characterization makes for great entertainment, it has also lead to the idea that shark attacks are the result of killing machines stalking easy prey instead of the mistaken identity accidents that they are. This, combined with a pronounced market for shark fins, liver, and other body parts has lead to a severe decline in several shark species across the globe.
Sharks are magnificent animals. They are the undisputed kings of the sea, at home and graceful in the ocean, beautiful and awe inspiring to watch. This beautiful animal, while dangerous, is something to be respected rather than feared; they are animals that offer far more in their exotic beauty than ever they could cut up in rare dishes and cuisine. Which is exactly what underwater photographer Michael Muller shows us in Sharks. Face-to-Face with the Ocean’s Endangered Predator.
This book, Muller’s first, presents the culmination of over a decade’s worth of close encounters with sharks both small and gargantuan, both fierce and gentle, both rare and common. The photographs show incredible beauty at close range and in their natural habitats, all the better to help us overcome our fears, the better to see sharks for the graceful animals they are.
Presented by Taschen, this book is huge, beautiful, and comprehensive. Arranged geographically, the photos are printed on heavy, matte paper that allows a full range of colors and tones. The photos are also presented without context. Rather each photo is given its own page or two (or three or four in the gatefolds) and explanations and details are saved for the picture index in the final pages. Additional indices include essays by Philippe Cousteau, Jr. and Dr. Alison Kock detailing the need for conservation efforts as well as an overview of Muller’s work and technique by Arty Nelson. Perhaps the most important, or maybe just most interesting index is the Species Notes, written by Dr. Kock, which includes each species place on the Red List of Threatened Species.
This is an amazing, hefty (seriously, you’re gonna need a bigger boat, er, shelf) tome full of stunning photos of wildlife at its most majestic. Pick up a copy for the photographer and wildlife lover in your life and, next time you see a shark on the big screen in the role of bad guy, maybe try to see things from its point of view? – Joel Neff
