Collaborate Disseminate
Gearheads love noisy engines, but this enthusiasm is rarely shared by the general public – hence, the UK is trialing new noise camera technology. Just like speed cameras, they’ll sit by the roadside watching and listening 24/7 to identify and… Continue reading UK noise cameras are coming to silence thunderous exhausts
There are many annoying issues associated with desktop 3D printers, but perhaps none are trickier than keeping the machine at the proper temperature. Too cold, and printed parts can warp or fail to adhere to the bed. Too hot, and the filament can get soft and jam, or the motors will start clanking and missing steps. High-end industrial 3D printers have temperature-controlled enclosures for precisely this reason, but the best you can hope for with a printer that’s little more than some aluminum extrusion and an Arduino is a heated bed that helps but is no substitute for the real …read more

Everyone loves firing up that CNC router for the first time. But if the first thing you cut is wood, chances are good that the second thing you cut will be parts for some kind of dust shroud. Babysitting the machine and chasing the spindle around with a shop vac hose probably isn’t why you got it in the first place, right?
Trouble is, most dust-management designs just don’t get the job done, or if they do, they obstruct your view of the tool with a brush or other flexible shroud. [Jeremy Cook] figured he could do better with this …read more

What good is safety gear that isn’t used because it’s annoying and gets in the way of getting the job at hand completed? None, really, and the solder fume extractor is one item that never seems to live in harmony with your workspace. They’re often noisy, they obstruct your vision, and a power cord draped across your bench is a sure way to ruin your soldering zen.
To fix those problems, [Nate] has built a nice battery powered solder fume extractor that’s so low profile and so quiet, you won’t mind sharing a bench with it. Based on a standard …read more

A lot of work has gone into hacking common items (like IKEA Lack tables) into useful and effective 3D printer enclosures, but [Stefan.Lu] has taken a harder look at the whole business. He decided to start with some specific goals that were unmet by current solutions. In particular, he wanted to allow for proper ventilation and exhaust. Not only do some filaments smell bad, but there is ongoing research around UFP (ultra-fine particles) emitted from the 3D printing process. Just in case UFPs turn out to be this generation’s asbestos or something equally terrible, [Stefan.Lu] felt that a bit more …read more

[Frank Howarth] has a shop most woodworkers would kill for, stuffed with enough tools to equip multiple hackspaces — four radial-arm saws alone! But while the CNC router in the middle of the shop, large enough to work on an entire sheet of plywood, is a gem of a machine, it was proving to be a dusty nightmare. [Frank]’s solution was as unique as his workspace — this swiveling overhead dust extraction system.
The two-part video below shows how he dealt with the dual problems of collection and removal. The former was a fairly simple brush-bristle shroud of the type …read more

As if slinging around 40 watts of potentially tattoo-removing or retina-singeing laser beams wasn’t anxiety-inducing enough, now comes a new, scary acronym – LCAGs, or “laser-generated airborne contaminants.” With something that scary floating around your shop, it might be a good idea to build a souped-up laser cutter exhaust fan to save your lungs.
We jest, but taking care of yourself is the responsible way to have a long and fruitful hacking career, and while [patternmusic]’s “Fume Coffin” might seem like overkill, can you go too far to protect your lungs? Plywood and acrylic, the most common materials that come …read more

Don’t you just hate it when you spend less than $400 on a 40-watt laser cutter and it turns out to have a work area the size of a sheet of copy paper? [Kostas Filosofou] sure did, but rather than stick with that limited work envelope, he modified his cheap K40 laser cutter so it has almost five times the original space.
The K40 doesn’t make any pretenses — it’s a cheap laser cutter and engraver from China. But with new units going for $344 on eBay now, it’s almost a no-brainer. Even with its limitations, you’re still getting a …read more

Nothing says swinging 21st-century bachelor pad better than a laser cutter. To really make a statement, you want a custom-built, 100 Watt, 1200mm x 900mm laser cutter.
The bachelor in question, [drandolph], rightly points out that a $6,000 build that takes up a significant fraction of the floor space in one’s apartment is better attempted without the benefit of spousal oversight. Still, what spouse couldn’t love the finished product? With a custom aluminum extrusion frame (which barely made the trip from China intact) it’s a sturdy affair, and who could deny the appeal of the soft glow of an LED-illuminated …read more
