Making Tension Based Furniture

Posted on by

[Robby Cuthbert,] an artist and designer based out of Palo Alto, California is creating stable cable tables that are simultaneously a feat of engineering and a work of art.

[Cuthbert’s] tables are held together by 1/16″ stainless steel cables that exert oppositional tensions that result in a structurally stable and visually appealing coffee table. In his video, [Cuthbert] leads us through his process for creating his tables, step by step. [Cuthbert] starts by cutting out bamboo legs on his CNC mill. He then drills holes in each leg for cables and mounts each leg on his custom table jig. Then, …read more

Easy DIY Microfluidics

Posted on by

Microfluidics, the precise control and manipulation of small volumes of liquids, is heavily used in any field that does small-scale experiments with expensive reagents (We’re looking at you, natural sciences.) However, the process commonly used to create microfluidic devices is time and experience intensive. But, worry not: the Uppsala iGEM team has created Chipgineering: A manual for manufacturing a microfluidic chip.

Used while developing everything from inkjet print heads to micro-thermal technologies, microfluidic systems are generally useful. Specifically, Uppsala’s microfluidic device performs a simple biological procedure, a heat-shock transformation, as a proof of concept. Moreover, Uppsala uses commonly available materials: …read more

How to Trick Your Electrical Meter By Saving Power

Posted on by

A group of Dutch scientists have been testing out some of today’s “smart” electrical meters to check their accuracy, among other things. Not ones to disappoint, the scientists have found consistently false readings that in some cases are 582% higher than actual energy consumption.

With experiments lasting for six months, the researchers tried to focus on meters representative of those commonly used in the Netherlands and manufactured between 2004 and 2014. Moreover, the researchers tried to reproduce standard household energy consumption patters rather than focusing on stress tests.

Their results? Well, “results varied wildly, with some meters reporting errors way …read more

Canary for USB Ports

Posted on by

If you’re a paranoid system admin, [errbufferoverfl] has your back with software that keeps track of whenever someone plugs in or disconnects an USB-based device from a workstation.

Christened USB Canary, [errbufferoverfl’s] tool is written in Python. However, even though Python is cross-platform, USB Canary only works on Linux currently. But, fret not: [errbufferoverfl] is already working on Windows and Mac versions.

Primarily, USB Canary watches USB connectors for any activity and logs anything it sees. Moreover, when a USB device is plugged in or unplugged, USB Canary can alert the owner of the workstation via an SMS message courtesy …read more

How to Find a Twitter Account

Posted on by

[Ashley Feinberg] is not one to say no to a challenge. When James Comey (the current Director of the Federal Bureau of Investigation for the United States of America) let slip that he has a secret Twitter and Instagram account, [Ashley] knew what she had to do.

At the beginning, [Ashley] knew only a few things: (1) Comey had recently joined twitter and (2) he only allows his “immediate relatives and one daughter’s serious boyfriend” to follow him. As such, [Ashely] deduced that “if we can find the Instagram accounts belonging to James Comey’s family, we can also find James …read more

New Wisdom on Old Practices

Posted on by

Getting into machining is hard. From high-speed seel versus carbide to “old US iron” versus “new Asian manufacture” to simply choosing which drill bits to buy, many hard decisions must be made before one even has a chance to gain experience. Fear not, [Quinn Dunki] has created “a roadmap for how to get involved in this hobby.”

We saw [Quinn’s] first entry in her lathe series back in January, and now the series is complete! Starting with the definition of a machine tool and ending with the famous Clickspring scriber and a multi-material pen, [Quinn] leaves no stone unturned. [Quinn’s] …read more

Mycelia + Sawdust = House?

Posted on by

Take a guess. What is the featured picture for this article? If you’re channeling your inner Google image recognition, you might say: “Best guess for this image: rock.” But, like Google, you’d be wrong. Instead, what you see are bricks made out of fungi obtained from tissues of mycelia.

By taking fungi obtained from tissues of mycelia and storing them in a jar filled with a growth medium (usually sawdust), MycoWorks is creating all sorts of materials with exciting properties. In just three to seven days, the fungi and sawdust mixture expands and forms into clumps of material, which …read more

An Eggcelent Eggspriment

Posted on by

After multiple iterations [Keef] has nailed down the fabrication process for an unusual component. Using only a heater water bath, some silicone and easily available reagents, [Keef] demonstrate how he manufactures a gastronomic enigma: the long egg.

The similarities between [Keef’s] process and the typical hacker iteration cycle are eggceptional. He starts out with a goal and iterates, modifying his methods until he gets the perfect long egg. Sound familiar? Cooking can be as much of a science as it is an art.

In his quest, [Keef] utilizes sausage casing, plastic bags, sticky tape, “lots of sweat and almost some …read more

Microfluidic LEGO Bricks

Posted on by

Years ago, prototyping microfluidic systems was a long, time-intensive task. With inspiration from DIY PCB fabrication techniques, that time is now greatly reduced. However, even with the improvements, it still takes a full day to go from an idea to a tangible implementation. However, progress creeps in this petty pace from day to day, and in accordance, a group of researchers have found a way to use 3D printed molds to create microfluidic LEGO bricks that make microfluidic prototyping child’s play.

For the uninitiated, microfluidics is the study and manipulation of very small volumes of water, usually a millionth of …read more
