[Aaed Musa] has been building robot dogs for a long time now, so it was only natural that he would make one for the senior design project of his mechanical engineering degree. Since this meant working with potential customers, the requirements were somewhat more stringent than for previous dogs, but [Aaed] and his team were […]
Before the advent of electricity in the home made electrically-heated clothes irons a possibility, ironing was a cumbersome process, with self-heated irons being an arguable improvement over solid (so-called sad) irons that required heating in an external heat source like a stove or fire. These self-heating irons used a variety of fuels, with the one […]
Reading a book about bowling is not the same as actually bowling. If that resonates with you and you want to learn more about large language models, check out the LLM From Scratch project. The hands-on workshop lets you use a Mac, Linux, or Windows PC running Python and common libraries like numpy and torch […]
Screws are useful fasteners for 3D prints, but the effectiveness of a screw (not to mention the ease or hassle of insertion) depends on the hole itself. This comprehensive guide on how to design screw holes in 3D printed parts takes guesswork out by providing reference tables as well as useful general tips. The guide […]
The age of steam is long gone, but there are few railfans who don’t have a soft spot for the old rolling kettles. So you’d best believe when [AeroKoi] talks about 3D printed train whistles, that’s steam whistles. Generally speaking, Diesels have horns. You would not expect printed plastic to hold up to live steam– […]
If you talk to the FDA, there’s only one permanent method of hair removal—electrolysis. This involves sticking a needle into a hair follicle, getting it very hot or running a current through it, and then letting heat and/or the lye generated kill the root of the hair dead. Normally, you’d pay someone with a commercial […]
