Gareth’s Tips, Tools, and Shop Tales is published by Cool Tools Lab. To receive the newsletter a week early, sign up here.
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.
This two-sided page contains the wisdom of an entire book on how to write better. Nay, it distills an entire shelf of the world’s greatest writing manuals (and I have them all). After 30 years as both a writer and editor I can’t think of much I would add to these 50 short tips. This PDF is now my favorite guide to writing well. You can print it out for free. If you want its pithy reminders fleshed out with more examples, see the book form, or the website. But the free tip sheet itself — one paper printed both sides — rewards a quick review anytime you get down to serious writing.. – KK
There’s an emerging new media I use more and more: an online summary of a conference. Known as liveblogging, it presents a synopsis of each presentation, talk-by-talk, in nearly real time. This saves you time and money traveling to distant cities, and suffering through introductions and equipment failures. At its best, reading the liveblog can be better than attending the talk. All the chaff has been winnowed, and almost every talk captured. (Most conference attendees don’t even get to every talk.) Video recordings of conferences are becoming more popular, but a good liveblog is much quicker to scan and digest. But at its worse, a liveblog will offer little more than snarky comments about the speaker.
At the creation end, you need some skills to separate the best from the worst. Ethan Zuckerman, of Geek Corp, is one of the best conference bloggers alive. He teamed up with Bruno Giussani, another star liveblogger, to produce this free short 6-page PDF booklet on how to blog a conference with effectiveness. When you blog a conference it forces you to pay attention. My first book Out of Control began as an online blog of every talk at the first Artificial Life Conference (although no one called it blogging in 1987). The requisite focus of summarizing each talk clarified many ideas for me, and the response to the “blog” of the conference encouraged me to write a book. Other livebloggers find the same. They listen harder, and remember more.
Get good at this and you have a free pass to many high-priced conferences. Organizers are increasingly looking for first-rate livebloggers to generate press and future attendees. Or, like Ethan you can generate your own audience who follow you because your liveblogging skills. – KK
It’s relatively easy to blog good and great speakers: They follow a narrative path through their talks and speak at a pace the audience can understand. It’s harder to blog inexperienced speakers(because they may be too technical, confusing, fast, etc.) and multispeaker panels (because the discussion can take many different unstructured turns). But you don’t need to transcribe the whole talk, you need to capture the gist of it. A 20-minutes talk can often be summarized in a 20-lines post.
Always remember that what you’re writing will be read by people who weren’t in the room, so they haven’t seen the slides, the video, or the gesture. Hence, you have to compensate for the lack of context. Don’t be afraid to create a narrative by saying “He shows a slide with data on …” or “She walks on stage carrying a big suitcase” or “He shows a YouTube video” etc. And if the speaker shows a YouTube video, or a picture, remember that you’re online: Open another browser window, go to YouTube, find that video, and link to it; or go to the speaker’s website, find that picture or another similar or related item, and link to it (or republish the picture within your post). Yes, this requires effective multitasking. It’s at the root of conference blogging.
Conferences usually give out a program ahead of time. Use it to prepare for blogging: Do a quick Google search for each speaker, and save (in the same text file) links to their sites, blogs, and the institutions they’re affiliated with; write a one-or-two-sentences “biography” for each; and for the speakers you’ve never heard of, try to get a general sense of who they are and what they do. To write the mini-biography, use also the speaker information distributed by the conference organizers (booklet, website, etc.). For the key speakers, save a picture on your laptop (from their websites) and pre-format it for Web use, in case you will need it. If you prepare sufficiently, you’ve got the first paragraph of each post almost written ahead of time.
This is the best thesaurus there is. It supplies more synonyms, analogs, parallels, equivalents and comparable words in English than any other source, online or off. No other thesaurus comes near to it for completeness or breadth. Compiled in dictionary form, like the one in your word processors, there’s no index or cross-referencing. Just look up a word, any word, and it proceeds to overwhelm you with alternative choices (a total of 1.5 million synonyms are presented in 1,361 pages), including short phrases and only mildly related words. Rather than being a problem of imprecision, the Finder’s broad inclusiveness prods your imagination and prompts your recall.
Its single downside, however, is a major frustration: it is not available digitally, in a form compatible to the way most people write these days. It should live on your computer in a pull-down option, or plug-in for Word or the like. I’m totally baffled why it is not. As it is, it’s a huge fat book — a great book! — sitting within arm’s reach when I write, but not near enough for the power that it offers. – KK
