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.
Walking Pad: MERACH W50. I tried using a walking pad while working. It was fine during calls, but deep work while walking did not work for me. Then I made a rule: I can watch Netflix only while walking on the pad. That worked much better. I now easily reach 10,000 to 12,000 steps a day, and quite often more than 15,000.
Battery-Free Luggage Scale.We usually check one or two bags on family trips. I am also the person who really does not want to pay an overweight baggage fee. A luggage scale helps us check the weight before leaving and see whether there is still room for souvenirs. The problem with my old scale was the battery. Once, it died right before we left for the airport. This one has a tiny hand-powered generator inside. You push the button a few times, and it creates enough power to weigh the bag. No batteries and nothing to charge.
Tapo Smart Plugs. I do not like using the ceiling light in my home office. Instead, I have several lamps around the room. The light feels warmer and makes the office much nicer to work in. The annoying part was walking around and turning every lamp on and off. I connected them to Tapo smart plugs and grouped them together. Now I can control all the lamps with one tap in Apple Home or by saying, “Alexa (or Siri - I have both), turn on the office lights”.
DIGITAL
Spark Email. I have several email accounts for different purposes. Connecting all of them again every time I get a new device is annoying. I use Spark on two MacBooks, an iPhone, and an iPad. I connect my accounts once, and Spark syncs them across my devices. When I replace or upgrade a device, I do not have to set everything up again.
The Curious Procrastinator Newsletter. This is a weekly read about behavior, some of the psychology behind it, and useful technology. It mixes interesting ideas with personal stories and dry, self-sarcastic humor.
INVISIBLE
Answers are hidden in action, not thinking.
Many times, I do not know what to do. Sometimes I am not even sure what I am doing. But I have learned that I usually do not find the answer by searching or thinking longer. I find it by starting. Works every time.
