Brute Forcing Passwords with a 3D Printer

Many of us use a 4 digit pin code to lock our phones. [David Randolph] over at Hak5 has come up a simple way to use a 3D printer to brute force these passwords. Just about every 3D printer out there speaks the same language, G-code. The same language used in CAD and CNC machines for decades.

[David] placed a numeric keypad on the bed of his printer. He then mapped out the height and positions of each key. Once he knew the absolute positions of the keys, it was easy to tell the printer to move to a key, …read more

How Cheap Can A 3D Printer Get? The Anet A8

The short answer: something like $200, if your time is worth $0/hour. How is this possible? Cheap kit printers, with laser-cut acrylic frames, but otherwise reasonably solid components. In particular, for this review, an Anet A8. If you’re willing to add a little sweat equity and fix up some of the bugs, an A8 can be turned into a good 3D printer on a shoestring budget.

That said, the A8 is a printer kit, not a printer. You’re going to be responsible for assembly of every last M3 screw, and there are many. Building the thing took me eight …read more

What Actually Happens At A Hardware Hacking Con

The Hackaday Superconference was last weekend, and it was the greatest hardware con on the planet. What can you build out of a conference badge? If you answered “a resin-based 3D printer” you would have won a prize. If you decided to put your badge in a conference water bottle and make a stun gun you’d receive adoration of all in attendance. Yeah, it got that crazy.

At other tech conferences, you’ll find gaggles of nerds sitting around a table with MacBooks and Thinkpads. The Superconference is different. Here, you’ll find soldering irons, tackle boxes filled with components, and loose …read more

3D Printed Tyres Let You Drive on Water

[Jesus] apparently walked on water, without any tools at all. But when you’ve got a 3D printer handy, it makes sense to use it. [Simon] decided to use his to 3D print some tyres for his R/C car – with awesome results.

[Simon] started this project with a goal of driving on water. Initial experiments were promising – the first design of paddle tyres gave great traction in the sand and were capable of climbing some impressive slopes. However, once aimed at the water, the car quickly sank below the surface.

Returning to the drawing board armed with the advice …read more

This 3D Cable Printer Remixes the Delta

When last we ran into [Daren Schwenke] he was showing off his 6-color delta printer that changes colors seamless mid-print. Right now he’s working on a printer that uses tensioned cables to precisely move a toolhead while maintaining enough solidity that [Daren] can tap on the toolhead without it budging at all.

It’s much more simple a rig than a gantry-style 3D printer, with a chassis shaped like a geodesic polyhedron consisting of fiberglass trusses (those driveway markers) secured by 3D-printed lugs, all controlled by a Beaglebone Green and four steppers. A key element of the build is the central …read more

This 3D Printer Enclosure Takes Ventilation Seriously

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

3D Printing on the Subway; Or Anywhere Else!

3D-Printed wearable electronics are on the rise, however our own [Naomi Wu] flipped it around and made a wearable 3D printer which not only is portable but also manufactures on the move!

The project starts with a baby carrier that was locally purchased, and the extra fat was trimmed off leaving behind only the primary harness and square frame. This square frame is left intact to provide stability to the mounted printer as well as some level of comfort to the wearer. [Naomi] then drills a number of new holes in the delta printer in question, of which fortunately the …read more
