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.
For lightweight family-rated summer entertainment, try K-Pop Demon Hunters. It is an animated musical fairytale in the manner of Shrek or Frozen, but with Korean-American characteristics. In this fantasy, the battle is over fans, who are the scarce resource. Catchy K-pop songs score the fast action, which also delivers an emotional payoff. The film streams on Netflix, and is getting a lot of attention. It’s the meme source for this summer. — KK
Perfect first apartment tool kit
I got this Workpro Home Tool Kit as a gift for a relative moving into his first apartment. We used it to assemble flat-pack furniture, mount a TV, and install blackout curtains. The 12V cordless drill/driver, bits, wrench, pliers, level, utility knife, hammer, and tape measure handled everything we encountered. I’d add a socket set to round it out, but the kit contains all the essential tools a first-time apartment dweller needs. Everything stores in the included tool bag. — MF
Charting Wholeness
This chart, “A Guide from Pain to Presence”, explores how human expression changes when it is a reaction to past loss, future fear, or present discomfort. It also offers alternative expressions that stem from wholeness and embodiment. For example, personal boundaries may become forms of control or avoidance when motivated by past loss or fear of uncertainty, but when rooted in wholeness, boundaries express a healthy authority based on inner clarity. The language can be a bit jargon-heavy, but I find the framework helpful for shifting from old, anxious patterns to more intentional and grounded action. — CD
A creative follow
My favorite current New Yorker cartoonist is Roz Chast. I love her whimsy, childlike drawing, inventiveness, and silly sweet humor. But she creates more than cartoons. On her Instagram page, she posts weird painted eggs she makes, her marvelous embroidered dreams, her arrangements of Japanese matchboxes, her block prints, her photographs of New York shops at night, and more. It’s the most refreshing definition of being creative. I get inspired every visit. — KK
Smart scale for easy health tracking
My old bathroom scale was giving inconsistent measurements, so it was time to get a new one. I wanted something inexpensive, highly rated, with an easy-to-read LED display, and that could sync with my Apple Health app. The Fitindex Smart Scale checked all the boxes. The scale measures up to 400 lbs in 0.2 lb increments and runs on included AAA batteries. — MF
50 Ways to Unplug
The Analog Life: 50 Ways to Unplug and Feel Human Againoffers a great list of practical ways to go old-school and become less screen-centric. I love the advice to use devices that do one thing well, such as an e-reader, record player, or kitchen timer. My crystal radio—tuned to one station and one station only—is one of my favorite and most nostalgia-inducing possessions. All these tips help to reclaim a more intentional, analog way of living—like allowing days to go unaccounted for and enjoying experiences without feeling the need to document them. — CD
