Now as far as problems go, selling so many products on Tindie that you need to come up with a faster way to test them is a pretty good one to have. But it’s still a problem that needs solving. For [Eric Gunnerson] the solution involved finding a quick and …read more

The Practical Approach to Keeping Your Laser in Focus

You could be forgiven for thinking that laser cutters and engravers are purely two dimensional affairs. After all, when compared to something like your average desktop 3D printer, most don’t have much in the way of a Z axis: the head moves around at a fixed height over the workpiece. …read more

Custom Inflatables Are Only A Laser Beam Away

Carl Sagan one said “If you wish to make an apple pie from scratch, you must first invent the universe.” It might not be a very accurate description of the relative difficulty level of baking, but the logic is sound enough: there’s often a lot of ground work that needs …read more

K40 Gets A Leg Up With Open Source Z Table

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

Dual Source Laser Cutter Built Like a Tank, Cuts Most Anything

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

Laser Cutter Turns Scrapped To Shipped

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

The Internet of Three-Pointers

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
