If you’ve done even the most cursory research into buying a laser cutter, you’ve certainly heard of the K40. Usually selling for around $400 USD online, the K40 is not so much a single machine as a class of very similar 40 watt CO2 lasers from various Chinese manufacturers. As you might expect, it takes considerable corner cutting to drive the cost down that low, but the K40 is still arguably the most cost-effective way to get a “real” laser cutter into your shop. If you’re willing to do some modifications on the thing, even better.
One of the shortcomings …read more
Laser cutters aren’t the sort of thing that you might think about making at home, but there’s no reason not to if you are careful and do your research. That’s what [Daniele Ingrassia] did with the Laser Duo, an open source laser cutter that has two light sources for cutting various materials. His final product is not a small device: it has a press-formed aluminum case that looks more like a World War I tank than a piece of precision machinery. But that’s for a good reason: you don’t mess about with lasers, especially the 130 Watt CO2 and 75 …read more
We’ll go way out on a limb here and say you’ve probably got a ridiculous amount of flattened cardboard boxes. We’re buying more stuff online than ever before, and all those boxes really start to add up. At the least we hope they’re making it to the recycling bin, but what about reusing them? Surely there’s something you could do with all those empty shipping boxes…
Here’s a wild idea…why not use them to ship things? But not exactly as they are, unless you’re in the business of shipping big stuff, the probably won’t do you much good as-is. Instead, …read more
When tossing something into the rubbish bin, do you ever concoct that momentary mental scenario where you’re on a basketball court charging the net — the game’s final seconds ticking down on the clock — making a desperate stretch and flicking some crumpled paper perfectly into the basket only for no one to notice your awesome skills? Well, now you can show off how good you are at throwing out garbage.
Well, not strictly garbage. The genesis of this IoT basketball hoop was in fact an inflatable ball on [Brandon Rice]’s desk that he felt would be more fun to …read more
Who would have thought you could make a game out of an optical bench? [Chris Mitchell] did, and while we were skeptical at first, his laser Light Bender game has some potential. Just watch your eyes.
The premise is simple: direct the beam of a colored laser to the correct target before time runs out. [Chris] used laser-cut acrylic for his playfield, which has nine square cutouts arranged in a grid. Red, green, and blue laser pointers line the bottom of the grid, with photosensors and RGB LEDs lining the grid on the other three sides. Play starts with a …read more
If you have a 3D printer, you’re surrounded by plastic trash. I’m speaking, of course, of failed prints, brims, and support material that builds up in the trash can near your printer. Although machines that turn that trash into filament exist, they’re not exactly common. But there’s another way to turn that waste into new building materials. [flowalistic], 3D designer extraordinaire, is using that trash to create panels of plastic and throwing that into a laser cutter. It’s a plastic smoothie, and if you can sort your scrap by color, the results look fantastic.
The first step in turning garbage …read more
The distinctive blue-and-white enclosure of the Chinese-made K40 laser cutter has become a common sight in workshops and hackerspaces, as they represent the cheapest route to a working cutter that can be found. It’s fair to say though that they are not a particularly good or safe machine when shipped, and [Archie Roques] has put together a blog post detailing the modifications to make something better of a stock K40 performed at Norwich Hackspace.
After checking that their K40 worked, and hooking up suitable cooling and ventilation for it, the first task facing the Norwich crew was to install a …read more
What’s better than a cool build? A cool build with valuable advice! Add a few flashy pictures and you have [Martin Raynsford]’s Reuleaux triangle coasters blog post. [Martin Raynsford] wanted to share his advice about the importance of using jigs and we’re sold. He was able to make 100 coasters in a single day and if he’s like us, after number ten, the work gets a little hurried and that is when mistakes are made.
Jig is a broad term when it comes to tooling but essentially, it holds your part in place while you work on it. In this …read more
This year at Maker Faire, laser cutters were all the rage. Dremel announced a 40W laser cutter, but it won’t be available for purchase until this time next year, there is no price yet, and therefore doesn’t deserve further mention. Glowforge was out in full force, but the most interesting aspect of the Glowforge — a compact filter system that sits right underneath the laser — was not to be found. It looks like lasers are the next 3D printer.
Of course, those in the know have already been using laser cutters for years, and there are options for desktop …read more
A while ago, [Marco] mounted a powerful laser diode to a CNC machine in an attempt to etch copper clad board and create a few PCBs. The results weren’t that great, but the technique was promising. In a new experiment, [Marco] purchased a very cheap laser engraver kit from China, and now this technique looks like it might be a winner.
[Marco] sourced his laser engraver from Banggood, and it’s pretty much exactly what you would expect for a CNC machine that costs under $200. The frame is aluminum extrusion, the motors are off-the-shelf steppers, the electronics are just Pololu-like …read more
