X-acto knives are popular as the scalpel of the craft world. Obviously, holders for the blades are available off-the-shelf, but you needn’t settle for store bought. [Ariel Yahni] set about making an X-acto handle of their own, and it shows just how quick and easy making your own tools can be. The blades are first […]
Perhaps you’ve played a flight simulator before, using something like a mouse and keyboard. That’s a fine experience, but like any other activity you can get a lot more out of it if you put a little more effort into the experience. Some will upgrade to a joystick for a modest improvement, and others will […]
[Amon] built an induction heater to break stuck bolts loose. If you work on cars, machines, or anything big and metal, sooner or later you’re going to run into stuck nuts and bolts. Getting them unstuck usually involves penetrating oil, heat from a torch, and cheater bars. Heat usually works well, as heating the bolt […]
TV’s MacGyver would love the breadboard arrangement we saw recently: it uses paperclips and crimping to make circuits that can be more or less permanent with no soldering. The basic idea is simple. A cardboard base has a piece of paper affixed. Metal paperclips are bent straight and glued to the paper using PVA glue […]
CNC machining is a wonderful thing, taking away a lot of the manual work required in machining and replacing it with accurate, repeatable computer control. However, this doesn’t mean that you can simply click a few buttons and become a great machinist overnight. There are a wide variety of skills involved in utilizing these tools […]
Have you ever seen a product in the store and been shocked at what the manufacturer was trying to charge for it? Since you’re reading Hackaday, we can safely assume the answer to that question; building a homebrew version of some commercial product for a fraction of its retail price is practically a rite of […]
Air compressors are often loud, raucous machines – but they don’t have to be. [Eric Strebel] built a remarkably quiet compressor using parts salvaged from an old fridge. After several years of use, it was due for an upgrade (Youtube link, embedded below}. While performance of the original setup was good, [Eric] desired a compressor […]
The 3D printing community is simply stirring with excitement over toolchanging printers, but these machines are still the exception rather than the norm. Here’s an exceptional exception: [Paul Paukstelis] built a five-color printer with a novel head-changing solution. [Paul’s] 3D printer is a hat-tip to anyone who’s spent time in the wetlab. For starters, the […]
Here at Hackaday, we thought we’d seen every method of making PCBs: CNC machining, masking and etching with a variety of chemicals, laser engraving, or even the crude but effective method of scratching away the copper with a utility knife. Whatever works is fine with us, really, but there still does seem to be room […]
CNC builds come in all shapes and sizes. There’s delta manipulators, experimental polar rigs, and all manner of cartesian builds, large and small. After completing their first CNC build, [jtaggard] took what they learned and applied it in the development of a new machine. It’s a desk-sized cartesian design, with a frame built from V-slot […]
