Comparing Circular Saw Blades
In this Project Farm video, Todd tests 15 different circular saw blades to find out which ones are the best. He tested blades for performance in ripping 2×4 lumber (before and after striking nails) and compared for performance while cutting through oak and ripping an 8’ pressure-treated 4×4. Bottom line? The Makita blade ($10) was best overall. The Spyder also performed surprisingly well for its $5 price tag (at time of testing), although that price is currently over $12 each, so look for it on sale. Doing a web search, I see it’s available at some e-tailers for under $7.
Cutlist Optimizer
Speaking of cutting things. If you have a woodworking project that involves a fairly complicated cut list, there is a free app called Cutlist Optimizer. It allows you to both organize your cut list to better keep track of all of your pieces and allows you to optimize the parts you can get from your sheet goods.
How to Calculate 555 Timer Frequency and Duration
Ah, the venerable 555 chip. One of the most useful and popular ICs in electronics history. Invented in 1971, released in 72, it remains a go-to solution for a myriad of timer, delay, pulse, and oscillation applications. In this Digi-Key video, they cover the steps for calculating the necessary resistor and capacitor values needed to achieve the frequency and signal duration that you’re after in your project.
The Power of Great Reference Books and Knowing the Names of Things
As both a maker and a word nerd (I edited Wired’s “Jargon Watch” column for 13 years), I’ve always tried to impress upon people the power in knowing what something is called. Knowing the proper name for something allows you to look it up, learn about it, track it down (if it’s a tangible object). In this Adam Savage video, he harps on the same thing. He does so while extolling the virtues of a book he recently discovered and loves, the Backstage Handbook. This visual technical reference is for stagecraft, but most of its contents–divided into tools, hardware, materials, shop math, electrics, and architecture–can be applied to all manner of making. You you get to learn the proper names for all of the tools, hardware, and materials it covers. Magic!
TOYS! StylusReach Flexible Flashlight
Cool Tools has launched a new newsletter called Tools for Possibilities. Every week, subscribers get sent a page from the CT book: Cool Tools: A Catalog of Possibilities. I was tickled to see that the first page I was sent had a review that I wrote on the StylusReach flashlight. The Cool Tools catalog was released in 2013. Nine years later and I still have, use, and love this flashlight. Good tools do that.
Newsletter reader Paco Hidalgo sent this in response to the piece in the last issue on water and baking soda as a CA glue accelerator.
“I first tried the Zip Kicker CA accelerator and found its smell very disagreeable, nauseating, and the spray bottle made it very difficult to apply just a small drop. I later leaned that cyanoacrylate glues “set” (polymerize) by the mere presence of trace amounts of water vapor in the atmosphere. This infographic explains.
“So, I concluded that if that is the case, then liquid water would certainly accelerate the polymerization. I found that just a drop of water from a toothpick or needle onto a blob of the glue does indeed accelerate the setting process. I never heard of using baking soda but that would add a foreign material to the bond. Why do that? [See comment below] There would be no reason to mix baking soda with water since water alone does a good job.
“BTW: A ‘secret’ that I learned from the guy at the counter of a mall hobby shop, is that CA glues will keep indefinitely in the freezer. I think the dry environment prevents the glue from polymerizing. The manufacturers don’t want you to know that so they tell you not to freeze their glues. I keep partial bottles of different types of CA glue, including LOCTITE, sealed inside a ziploc bag in the freezer that are at least 10 years old. I can take a bottle and use it immediately without waiting for it to come to room temp. It is liquid and works just as fast. I wipe the tip with acetone after each use and keep a common pin in the narrow opening so it doesn’t clog.
“I keep all my solvent glues, including Lexel, E6000, and Goop in the freezer too, with the same result. I think the cold environment keeps the solvent from evaporating and escaping from the imperfect seal that normally shortens the shelf life. I keep epoxy glues in the refrigerator. This is enough to prevent them from self-polymerizing.”
[Just to clarify: Baking soda is commonly used by itself as an accelerator, especially in the hobby/modeling communities. Besides being an accelerator, it adds more structure to the join. Large amounts of baking soda can be added to CA glue to create a very hard material. This soda and CA combo as a structural material is common among luthiers repairing bridges and fret boards. It can be sanded, drilled, etc.]

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.
It is remarkable how much we learn in our youth and how fast we learn it. It is a pace that really cannot sustain itself as we age, though we might try to continue to learn as though we were young. In my youth, the newspaper seemed a vast swarm of text and a few images that encircled a hidden prize: the funnies. Comics, in youth, are acceptable, but as we age we regard them more as juvenile diversions. Over time, the picture book gives way to the novel. The non-fiction works in the form of text books and scholarly journals are tools to educate us. Finally, should we pursue learning down the institutional path long enough, we encounter doctoral theses with their many and myriad intertextual references. It is a long-standing joke among academics that it is rare that the thesis they slave over for four or more years ever actually gets read.
Nick Sousanis, with his doctoral thesis Unflattening, is a poignant departure from any trend of dissertations written for the sake of being written. More than that, it is meant to be more than a read work. It is an experiential work that asks the reader to not just read, but rather to participate in learning to appreciate imagery on equal terms with orderly lines of written text. This is a dissertation written in comic book format that argues for the power of that medium. One might think about the adage concerning the worth of pictures and thousands of words, and that does come up in the work itself, but this is something more than a trite saying. It is a masterful reinterpretation of how we read and learn, and how our world can be captured and conveyed to our fellows. It dismantles the rigid presumptions we have regarding the inherent value of the written word – especially scholarly writing. It champions the comic, for “while the image is, the text is always about.” Indeed, it is brilliantly argued throughout that “the visual provides expression where words fail.”
The title, Unflattening, refers to Edwin A. Abbott’s novella Flatland (1884), about a dystopian flatland of two dimensional objects, where a coin would not be seen by others for its circular shape, but rather would be seen edge-on as just a line obscuring the horizon. This is a “linelander,” and all linelanders see each other this way. A square of three dimensions frees the coin-shaped object by peeling it from the flat surface so that it might see its brethren and world from above – from the third dimension, just as we would look down upon a page in a geometry textbook
Sousanis, similarly, wishes to peel us away from the linear predominance of the textual world where word follows word follows word. He comes from a background in comics, graphic novels, or whatever phrase you would use to describe his art. Just as his square peels away the coin from lineland to reveal it to be flatland, so too Sousanis convinces us, by both text and deed, of the power of comics. His text is often sparse and pared down to its most necessary elements, but the accompanying visuals draw the eye along and serve as an obvious example that reinforces the sometimes vague text. The deed is the image, for it is the more obvious representation of our lived world, while the text can only describe it. This may all seem obvious, but Sousanis brings to bear so many examples and graphical displays to reinforce his line of argument, that the journey through this work is quite remarkable. Moreover, his endnotes at the back serve not only to acknowledge his textual sources, but also to draw attention to and explain his visual inspirations. Those images that so often sit confined within frames within museum galleries or as a ghettoized section of glossy pages in the middle of an art book, they are given life and agency by Sousanis’ deploying of them as allies to his words.
Certainly, it is almost with chagrin that one must only write about such a work when it argues so convincingly that mere text is limited in its conveying of full meaning. It is some solace that the accompanying images from Sousanis’ work will allow readers of this review to gain greater insight in the majesty of his pairing of imagery and text. This is a thinking person’s book and it is most definitely academic, but it is also surprisingly accessible. It draws upon – and draws – so many disciplines and so many real-world instances, that anyone and everyone will find it illuminating. So profound are many of these moments of illumination that they go a long way to rejuvenating our desire to see the world anew, from a child’s eyes once more. – Stephen Webb.
FOR FANS INTERESTED IN THE HISTORY AND INSPIRATION BEHIND A BOY AND HIS TIGER
Exploring Calvin and Hobbes: An Exhibition Catalogue by Bill Watterson and Robb Jenny Andrews McMeel Publishing 2016, 160 pages, 8.5 x 11 x 0.6 inches
I like many grew up on Calvin and Hobbes. I don’t know if there’s a comic, book, film, or any other piece of art that better captures a childhood. I read every Sunday strip, most of the dailies, and the ones that I missed I would read in dog-eared collection books checked out from the library. As I got older, I wanted to know more about the strip’s creation. When I picked up the Complete Calvin and Hobbes, a 14-pound tomb, I was a little disappointed. Other than an introduction, there was very little information about the mysterious creator Bill Watterson. Thankfully, Exploring Calvin and Hobbes: An Exhibition Catalogue makes up for that.
This is the Blu-Ray extras that Calvin & Hobbes fans have been waiting for. It’s not for those casually interested in reading the strip. There are plenty of other books for that. But if you’re interested in process, history, and the inspiration behind a boy and his tiger, you’re going to love this book.
The book explores an exhibit of Watterson’s work at the Billy Ireland Cartoon Museum. It also includes one of the most in-depth interviews he’s ever given. In it you get a rare look at his early work, the tools Watterson used, the struggles he went through, and the wonderful comic that he created. You get a real sense of the artistry that Watterson put into the strip, and how it evolved over the years. It’s great to relive and learn about something that had such an influence on me. This book is definitely a must-have for Calvin and Hobbes fans. – JP LeRoux
