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.
Co-founder Kevin Kelly and I both swear by no-metal belts for airport days and we also like the fact that these military-style webbed ones don't have holes either, so they fit precisely no matter what's going on with your waistline. I've been using the same one for five years and it looks like new. There's a stream of very similar ones on Amazon with Chinese names, but this brand has the highest ratings and you get two (of different colors) for under $20, with Prime shipping.
Tough Solar-powered Watch
Speaking of travel gear that holds up well, I've passed the 12-year mark on the watch I wear the most when traveling: My Casio solar-powered one with an altimeter. I've never replaced the battery because it recharges from sunlight. Even when it sits in a drawer for months though, it doesn't wear down because the display turns off to save power. Prices range from $35 to $350 and that vast range stems from how deep they can go in the water and what features they have, so if you don't care about underwater strength, the altimeter, or other features, then you can go with the low end at this page. Some have analog dials too.
The Return To Office Tug-of-war
Corporate efforts to get people to commute to cubicles again are not going well. Widespread employee satisfaction drops in surveys seem to be correlating closely with back-to-office demands. When dating app Grindr demanded that its workers return to the office, almost half of them said, "No thanks" and quit. At Amazon, efforts to drive workers back to the office have become a PR nightmare for the company and led to very public departures and protests. Meanwhile, remote companies are finding higher worker satisfaction, less turnover, and more diversity in their workforce. Remote work is a godsend for those who are trying to balance work demands with taking care of the kids, so why are "pro-family" leaders so hung up on butts in office seats? I believe the most obvious explanation is the most plausible: roughly half of commercial office space is sitting empty and a lot of powerful people own those buildings—or collect taxes from them.
Earth-friendly Toiletries in Europe
We tend to be North America-centric in this newsletter since that's where we and the biggest chunk of our readers are from, but here's one for the Europeans. Reader Mira replied to my earlier post about planet-friendly toiletry packaging with a recommendation for a Dutch company called Lekker. They make organic, sustainably packaged items like deodorant, lip balm, sunscreen, and soap. They ship all over Europe and in the Netherlands shipping is free with a minimum 35-euro spend.
