The Hunt For Red October In A Bathtub

Posted on December 1, 2016 by Brian Benchoff

Anything can be a remote controlled airplane, and ‘copters – quad or not – simply beat the air into submission. Remote controlled cars are easy, and RC tanks can even shoot their guns. One type of vehicle has eluded remote control hobbyists to a large extent; building a remote control submarine is hard. Not only do you have buoyancy to worry about, but you also need a way to keep the dry parts dry, all while operating in an environment where radio doesn’t really work well.

[Ivan] has already built RC planes, but wanted to tackle a new challenge. He …read more

Founding A Company In Shenzhen For Eight Days

Posted on November 30, 2016 by Brian Benchoff

Nadya Peek is one of the hackers that should require no introduction for the regular Hackaday reader. She is a postdoc at the Center for Bits and Atoms at the MIT Media Lab. She’s responsible for Popfab, a CNC machine that fits in a suitcase and one of the first implementations of a Core XY stage we’ve seen. Nadya has joined the ranks of Rudolf Diesel, Nikola Tesla, Mikhail Kalashnikov, and George W.G. Ferris by having a very tiny piece of the Novena laptop bear her name. She’s built cardboard CNC machines, and taken the idea of simple, easy to …read more

Slack, Backwards Compatible With 1982

Posted on November 30, 2016 by Brian Benchoff

Slack is great, but there are a few small problems with the current implementations. There isn’t a client for Palm, there isn’t a client for the Newton, and there isn’t a client for the Commodore 64. The last of these severe oversights was recently fixed by [Jeff Harris]. He built a native Slack client in 6502 assembly for the Commodore 64.

When dealing with network applications and the C64, the first question that comes to mind is how to talk to the outside world. There are C64 NICs, and ESP dongles, but for this build [Jeff] turned to the C64 …read more

HiFive1: RISC-V In An Arduino Form Factor

Posted on November 29, 2016 by Brian Benchoff

The RISC-V ISA has seen an uptick in popularity as of late — almost as if there’s a conference going on right now — thanks to the fact that this instruction set is big-O Open. This openness allows anyone to build their own software and hardware. Of course, getting your hands on a RISC-V chip has until now, been a bit difficult. You could always go over to opencores.com, grab some VHDL, and run a RISC-V chip on an FPGA. Last week, OnChip released the RISC-V Open-V in real, tangible silicon.

Choice is always a good thing, and now SiFive, …read more

Parametric 3D Printable Wheels And Treads

Posted on November 29, 2016 by Brian Benchoff

When it comes to robotic platforms, there is one constant problem: wheels. Wheels have infinite variety for every purpose imaginable, but if you buy a wheeled robotic chassis you have exactly one choice. Even if you go down to the local Horror Freight, there’s only about five or six different wheels available, all of which will quickly disintegrate.

To solve this problem, [Audrey] created OpenWheel, a system of parametric, 3D-printable wheels, tweels, tires, and tracks for robotics and more.

Like all good parametric 3D-printable designs, OpenWheel is written in OpenSCAD. These aren’t 3D designs; they’re code that compiles into printable …read more

Building Beautiful Cell Phones Out Of FR4

Posted on November 28, 2016 by Brian Benchoff

Over on Hackaday.io, [bobricius] took this technology and designed something great. It’s a GSM cell phone with a case made out of FR4. It’s beautiful, and if you’re ever in need of a beautifully crafted burner phone, this is the one to build.

The components, libraries, and toolchains to build a cellphone from scratch have been around for a very long time. Several years ago, the MIT Media Lab prototyped a very simple cellphone on a single piece of FR4. It made calls, but not much else. It was ugly, but it worked. [Bobricius] took the idea and ran with …read more

Neutralizing Intel’s Management Engine

Posted on November 28, 2016 by Brian Benchoff

Five or so years ago, Intel rolled out something horrible. Intel’s Management Engine (ME) is a completely separate computing environment running on Intel chipsets that has access to everything. The ME has network access, access to the host operating system, memory, and cryptography engine. The ME can be used remotely even if the PC is powered off. If that sounds scary, it gets even worse: no one knows what the ME is doing, and we can’t even look at the code. When — not ‘if’ — the ME is finally cracked open, every computer running on a recent Intel chip …read more

Contribute To Open Source On #OpenCyberMonday

Posted on November 28, 2016 by Brian Benchoff

Today is Cyber Monday, the day when everyone in the US goes back to work after Thanksgiving. Cyber Monday is a celebration of consumerism, and the largest online shopping day of the year. Right now, hundreds of thousands of office workers are browsing Amazon for Christmas presents, while the black sheep of the office are on LiveLeak checking out this year’s Black Friday compartment syndrome compilations.

This is the season of consumption, but there’s still time to give back. We would suggest #OpenCyberMonday, an effort to donate to your favorite Open Source foundations and projects.

It’s not necessary to explain …read more

Hackaday Links: November 27, 2016

Posted on November 28, 2016 by Brian Benchoff

[Prusa]’s business is doing great. This year, he released the Prusa i3 Mk. 2, a four color upgrade to the printer, and sales are through the roof. There’s just one problem: Paypal just locked his funds. Prusa is turning away from Paypal and given Paypal’s history, this will eventually be worked out. Be warned, though: don’t use Paypal for your hardware business. We’ve seen this same story played out too many times before.

Those millennials are always on their phones. How do you get rid of that distraction? Airplane mode? No, that’s stupid. Put those phones in a metal box. …read more
