New Electronics Series from Becky Stern
My old Make: colleague, Becky Stern, has a new video series that she’s doing for the electronics component company, Digi-Key. Becky has always done an impressive job of explaining what can be intimidating technical information in an entertaining and digestible way. If this first installment, an introduction to LEDs, is any indication, this series looks to deliver more of her welcome brand of accessible tech education.
How to Get Clearer and Stronger Transparent FDM Prints
In this CNC Kitchen video, Stefan shows the special settings you can use to create superior-looking clear prints using an FDM (Fused deposition modeling)printer and clear filament. He also looks at how these parameters make your parts super strong.
Making Your Own Vinyl Stickers
If you’ve been attracted to the idea of creating your own custom vinyl stickers, this video shows you how. All you basically need is a crafting vinyl cutter (a few hundred dollars) and some sheets or rolls of vinyl material.
CA Glue Accelerator from Baking Soda and Water
One of the best takeaways from this Bill Making Stuff video (where he celebrates his 50th episode) is his tip for creating your own accelerator for CA glue. As you likely know, there are commercial accelerators, but they smell funny, have nasty stuff in them, and are combustible. You’re even supposed to wear eye protection when using them, though nobody does. You may also know about using baking soda as an accelerator. It works great, but it leaves a dusty powder on everything that you have to clean off. Bill mixes his baking soda with water in a spray bottle and has found that it works great and creates less mess. I will definitely be trying this.
How a Gas Pump Knows When to Turn Itself Off
If you’ve ever wondered how a gas pump nozzle knows when to shut off when your tank is full, this video reveals the clever design. Venturi tubes, Bernoulli principle, negative pressure — it turns out the design is far more complicated that you might expect. I always assumed it was some sort of an electronic sensor, but it’s purely mechanical.
“I was surprised to see a recommendation for the OXO sink strainer. I love OXO products, but that strainer is a disappointment to me. I do like the inversion feature, but stuff still gets stuck in and around the holes. The silicone gets slimy. I have black slime after a week in my kitchen drain, probably from teensy bits of lettuce and herbs and salad dressing. UGH. (Cleaning out the bowl with a paper towel before washing it seems to help.) I don’t know that a standard issue strainer would make me any happier (though I’d love to quit using so many paper towels). I’m glad yours pleases you; my experience is just different.”
This is a great example of that adage made popular by early hacker culture: “Your mileage may vary” (YMMV). When I posted my review of the strainer on Boing Boing, the first few responses were similar to Candy’s and I got nervous, thinking I had prematurely decided a tool was a winner without giving it an honest testing myself. But then the positive reviews came and they were the overwhelming sentiment. And on Amazon, it has 17.5K reviews at 4.7 stars. After a month, we are more than happy with ours, but, as in all things, YMMV. Thanks for sharing your experience, Candy!

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's been so long since I've used a portable transistor radio that it feels like advanced technology. The Prunus J-166 is an impressively capable pocket AM/FM radio for $10. It's about the size of an iPhone and has just three simple controls (tuning, volume, band switch) that make it intuitive to use. It also has a tuning indicator light, headphone jack, and battery indicator. Requires 2 AA batteries (not included). — MF
True country sizes
My mental image of country sizes has been wrong. The True Size Of... is an interactive website that lets you drag countries around a world map to compare their actual sizes without the distortion caused by standard map projections. It's shocking to see how countries change shape as you move them — drag Greenland into Africa and watch it shrink to a small fraction of its map projection! — MF
101 Rules of Effective Living
Esoteric author Mitch Horowitz recently launched his Substack newsletter, Mystery Achievement, where he shared a list of 101 rules for effective living, distilled from more than 30 years of reading “nearly every major work of inspirational literature produced or translated into English.” You can find the full list here. Below are some of my favorites.
6) Be willing to clean toilets and wash floors. 20) Get away from cruel people—at all costs. 38) Look people in the eye, recognize them, acknowledge them. 65) “To feel brave, act as if we were brave.” (William James) 69) Know your preferences, even if you cannot act on them. 77) Do your absolute best to carry your own load before bothering another. 81) “Be wise as serpents and harmless as doves.” (Christ) 83) Boredom invites trouble. 94) Accept paradox.
