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.
If you have a long-haul international flight coming up and you'll be in the back of the plane, this guide to the roomiest seats in regular economy could be useful. Noting seat pitch, width, recline ability, and roominess of the cabin, it's a list of which flights will be the most comfortable. I've been on two of them and will vouch that flying on Emirates in an Airbus 380 felt like going back in time to the 1980s, as in a far superior experience than what we're stuck with now most of the time.
Hidden Costs of Home Ownership
If your parents are asking you when you’re going to settle down and buy a house, you might want to send them this Bankrate article on how much it really costs to own a home. When you add in insurance, taxes, maintenance, and repairs, the average U.S. homeowner with an average house is paying an extra $18,118 every year on top of their hefty mortgage. (It’s much higher in states like California.) You could probably pay for a year’s worth of Airbnb monthly rentals in much of the world on that amount alone.
More People Can Stay in Thailand for 60 Days
Thailand’s visa rules change more often than I buy new shoes, but the latest tweak is a positive one all around. First of all, citizens of more countries can enter without getting a visa in advance, from 57 nations to 93. In a great change for nomads passing through, visa-free visitors can now stay in Thailand for up to 60 days, compared to the earlier limit of 30 days. Get the full story here.
Global Entry Renewal Delays
My wife applied to renew her Global Entry status back in December, paying and then getting reimbursed from a travel credit card. As of July 17, she’s still waiting for a response. Apparently that has become so normal that the agency is giving a two-year grace period: you can keep using the program (and TSA PreCheck) as long as you applied in time to renew. According to this article that has a response from the agency, 77% of applications are handled automatically and are swift, but the 23% that are randomly reviewed manually are getting stuck in a huge backlog.
