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.
Comfortable with Uncertainty by Pema Chodron - I treat this book as a daily devotional. I’m not a religious person but the act of reading one page per day and meditating on it is powerful and scratches my spiritual itch. Pema Chodron has written many books on meditation and mindfulness. Her writing is down to earth, conversational, and never ceases to make me think deeply.
Mini Binoculars - I have two windows in my home office and I love to sit at my desk and use these mini binoculars to observe nature in my yard. You can certainly spend a lot more money on fancy binocs but these are inexpensive and do the job well.
Bowflex 552 Adjustable Dumbbells - Staying fit and strength training have become big parts of my life as I have advanced into middle age. These dumbbells are easy to use, save a ton of space over traditional dumbbell sets and are well made. I’ve had them for years, use them 4 times weekly and they just keep on going.
DIGITAL
Internet Archive - From their website, “Internet Archive is a non-profit library of millions of free texts, movies, software, music, websites, and more”. You can spend hours here discovering live music, old books, videos, you name it. And it’s all free. Kind of what we all wanted from the internet when it began.
Perplexity Comet Browser - This is not just a browser, it’s also an AI assistant. It can do anything that Chrome, Edge or Safari can do but can also book a trip (including finding flights, hotels, etc.), browse your emails for specific information or give you recipe ideas for tonights dinner and order the ingredients for pick up from Wal Mart, etc. Perplexity is a great AI app and the integration to web browser/Ai Assistant just seems natural. It’s very new so it will only get better from here.
INVISIBLE
A lot of people prefer the comfort of a crowd to the responsibility of independent thought. — Shane Parrish
This quote is so appropriate to todays on line world. Shane Parrish is one of the most cogent thinkers around. His Sunday newsletter, Brain Food, bills itself to be a “signal in a world full of noise”. It truly is just that. There’s not a week that goes by where I don’t gain some insight from his critical thinking. He also has several great books and a fantastic podcast.
