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.
I carry a roll of the Velcro Plant Ties (see right) in my tool bag, but also keep One-Wrap Velcro strips in the shop. While they’re much more expensive, I’ve found the larger kind to be substantially bulkier and stronger. Here in Toronto, we have alternating weekly garbage, recycling, and green waste pickup. We also have rapacious raccoons. I found if I add a simple loop of One-Wrap, screw it into the side of the green bin and loop it over the locking bail of the bin, the raccoons cannot open it. I first tried Plant Ties. They just wouldn’t hold. For my purposes, a One-Wrap is good for about a year, after which it is easily replaced. It’s available in various colors and sizes. The lower-end of the One-Wrap line is a similar size to the Plant Ties, which are 13 mm wide; however, the One-Wrap also come as large as 22mm. It has deeper loop Velcro (thicker and fuzzier), and as the width of the tape increases, the size of the loops and their grip strength increases. Plant Ties really are great for handling all kinds of tasks, but One-Wrap is strong enough to bundle thicker rope, heavier hoses, and most importantly for me, they keep raccoons out of the recycling. – David Keldsen
To me, as a commuter, one of the most impressive parts of the EZ Pass toll-paying system is the hardcore industrial “velcro” tape they give you to attach your transponder to your windshield. It’s not really velcro, though – instead of hooks and loops, both surfaces have these tiny hard plastic mushroom-shaped things that grab each other by the hundreds and don’t let go. Both sides are the same, so there is only one tape (called selfmating). And unlike the loosy-fabricky velcro connection, the Dual Lock surfaces don’t join until you’ve positioned them exactly, and then pressed them together with a satisfying “chunk.” They’re primarily used in industrial applications as a replacement for mechanical fasteners, but I use mine to attach my iPod to my dashboard, and tools to the wall in my workshop. – S.S.

Parachute cord isn’t only light and strong (550lb. rating) for its size (5/32” diameter), it’s also more versatile than other types of rope because it can be dissected and parted out, cut and used for its braided nylon sleeve and/or seven separate core strands.
You can get an enhanced grip and a little added padding by using paracord to wrap tool handles. It’s also used for making lanyards. I recently inserted a length of ball chain into a parachute cord sleeve to make a hands-free flashlight for late-night dog walks. The nylon is a lot more comfortable around my neck than a ball chain, and the fit is perfect. – Spencer Starr
