PoC||GTFO 14 is now out. It’s a 40 MB PDF that’s also a Nintendo Entertainment System ROM, and a Zip archive. Pastor Laphroaig Screams High Five To The Heavens As The Whole World Goes Under. Download this, but don’t link – host it yourself. Bitrot will be the end of us all.

[Photonicinduction] is back. The guy best known for not starting an electrical fire in his attic has been working through some stuff recently. He got married, went to India, and he’s going to try to blow a five thousand amp fuse. Good on him.

There’s a certain segment …read more

MRRF 17: True Color 3D PrintingCMYKWHeaderbrianbenchoff

Sun, 26 Mar 2017 20:00:11 +0000

3D printing has evolved to a point where dual extrusion isn’t really that special anymore. A few years ago, a two-color frog print would have been impressive, but this isn’t the case anymore. The Midwest RepRap Festival is all about the bleeding edge of what 3D printers are capable of, and this year is no exception. This year, we were graced with a few true multicolor filament-based 3D printers. The biggest and best comes from [Daren Schwenke]. His Arcus 3D printer is a full color, CMYKW mixing printer that’s able to print in any color imaginable.

The electronics for this …read more

Oscillating Fan Controller Used As Relaymainbryancockfield

Sun, 26 Mar 2017 17:00:00 +0000

The most brilliant hacks we see aren’t always the thousand-dollar, multi-year projects spanning every facet of engineering. Rather, the most ingenious projects are ones that take an everyday thing and use it in a simple but revolutionary way. By that measure, it’ll be hard to top [Robert]’s latest hack which uses the controller board from an everyday oscillating fan to build a three-way remote-controlled relay board.

Most oscillating fans have a speed selector switch. What that does might be somewhat different between different types of fan, but in general it will select either a smaller portion of the fan’s motor …read more

CNC Turns Empty Cans into Action FiguresSoda Can Bots Widedp2cnk

Sun, 26 Mar 2017 14:00:00 +0000

[apollocrowe] at Carbide 3D (a company that does desktop CNC machines) shared a project of his that spent years being not-quite-there, but recently got dusted off and carried past the finish line. His soda can robot action figures were originally made by gluing a paper design to aluminum from a soda can, but [apollocrowe] was never really able to cut the pieces as reliably or as accurately as he wanted and the idea got shelved. With a desktop CNC machine to take care of accurate cutting, the next issue was how to best hold down a thin piece of uneven …read more

Printing Nintendo Portables With SLAmainlewinday

Sun, 26 Mar 2017 11:00:00 +0000

Downing] is no stranger to building portable consoles, employing all manner of techniques in the process. However, when it came time to start on this commission, [Downing] decided to take a different tack – employing a Form 2 SLA printer in this Nintendo 64 portable build.

Modifying home consoles to become portables often involves tricks like Frankencasing – hacking together original factory parts such as controllers, cases, and accessories, and using body filler and a lot of sanding to create a template for vacuum moulding, which then results in a seamless final product. It’s possible to get some really impressive …read more

How to Play the Bass With Marblesmainlewinday

Sun, 26 Mar 2017 08:00:00 +0000

Stringed instruments make noise from the vibrations of tuned strings, using acoustic or electronic means to amplify those vibrations to the point where they’re loud enough to hear. The strings are triggered in a variety of ways – piano strings are hit with hammers, guitar strings are plucked, while violin strings are bowed. Meanwhile, [Martin] from the band [Wintergatan] is using marbles to play a bass guitar.

[Martin] starts out with a basic setup. The bass guitar is placed on the workbench, while a piece of wood is taped to a tripod. The wood has a hole drilled through it, …read more

MRRF 17: E3D Introduces Combination Extruder And HotendAerobrianbenchoff

Sun, 26 Mar 2017 05:00:31 +0000

Since the beginning of time, or 2006, the ‘hot glue gun’ part of our CNC hot glue guns have had well-defined parts. The extruder is the bit that pushes plastic through a tube, and the hot end is where all the melty bits are. These are separate devices, even though a shorter path from the extruder to hotend is always better. From Wade’s gear extruder to a nozzle made from an acorn nut, having the hotend and extruder as separate devices has become the standard.

This week at the Midwest RepRap Festival, E3D unveiled the Titan Aero. It’s an extruder …read more
