Excuse Me, Your Tie Is Unzipped

If you ask your typical handyperson what’s the one thing you need to fix most things, the answer might very well be duct tape. But second place — and first place in some circles — would have to be zip ties. These little wonders are everywhere if you look for them. But they are a relatively recent invention and haven’t always had the form they have today.

The original zip tie wasn’t called a zip tie or even a cable tie. In 1958 they were called Ty-Raps and produced by a company called Thomas and Betts. Originally meant to improve aircraft wiring harnesses, they found their way into various electronic equipment and packaging uses. But they’ve also become helpful in very unusual places too. A policeman trying to round up rioters would have problems carrying more than a few conventional handcuffs. But flexible cuffs based on zip ties are lightweight and easy to carry. Colon surgeons sometimes use a modified form of zip tie during procedures.

History

Maurus Logan worked for the Thomas and Betts company. In 1956, he was touring an aircraft manufacturing plant. Observing a wiring harness being put together on a nail board, similar to how car harnesses are made, he noted that the cables were bundled with waxed twine or nylon cord. A technician had to tie knots in the cord, sometimes cutting their fingers and often developing calluses. In addition, the twine was prone to fungal growth, requiring special treatment.

Logan kept turning the problem over in his mind and tried various approaches. By 1958, he had a patent for the Ty-Rap. The tie was lightweight, easy to install, easy to remove, and inexpensive.

N-O-D-E Unveils Slick Tech News Site

There’s probably some axiom in professional journalism that says you shouldn’t give out free advertisement to your competitors — but since none of us have any formal training in this kind of thing and are just making it up as we go along — we’re more than happy to plug the brand-new MOSFET.net.

We like the option to ignore Reality.

Created by the mysterious hacker [N-O-D-E], the site is exceptionally minimal, providing an experience not entirely unlike a feed reader. Each story has a main image, a few sentences that describe what it’s about, and the ever-important link to the original source. There’s even a color filter applied on the images so they aren’t jarring when compared to the site’s monochrome color scheme. (If that all sounds familiar, it’s because Hackaday came up with the idea 18 years ago. But it’s cool, we’re not salty or anything.)

In all seriousness, the site looks very well done and will no doubt be a great resource for the community. A particularly interesting feature is that entries expire automatically after 30 days. This speaks to the goal [N-O-D-E] has for MOSFET.net — it’s designed to show you relevant tech news, and literally nothing else. The focus and simplicity is beautiful.

Here’s wishing all the luck to [N-O-D-E] in this new venture. We know better than most that it can be a difficult and sometimes thankless job, but we wouldn’t still be doing it all these years if it wasn’t worth the effort. The tech world is always growing and there’s plenty of room for everyone. In fact, a recent peek at the analytics revealed that Hackaday got more views in 2022 than at any time in its history. As far as we’re concerned, the future looks bright for everyone.

The Flight Of The Dremel

A few months ago we featured a model aircraft whose power plant came courtesy of an angle grinder. It was the work of [Peter Sripol], and it seems he was beseiged by suggestions afterwards that he might follow it up with a helicopter built using a Dremel rotary tool. Which he duly did, and the results can be seen in the video below the break.

The Dremel itself requires a gearing to drive the balsa-bladed rotor, and a tail rotor is mounted with its own motor at the end of a boom. The video has many entertaining failures which see him arrive at a set of balancing arms and a tailplane for stability. The result is a helicopter that flies after a fashion, and is even able to stay aloft for a few seconds rather than crashing to earth.

The machine lacks the full rotor pitch control of its commercial bretheren, indeed the only control is directional via the tail rotor. Still it deserves top marks for entertainment alone, and we wouldn’t mind a go ourselves. The original angle grinder craft can be seen here.
