Illumipaper: paper that can selectively illuminate to provide interactivity

Illumipaper is a well-developed prototype from Interactive Media Lab Dresden; the researchers behind it used a variety of techniques to create regular-seeming paper with all the traditional characteristics (it can be crumpled, folded, written on with pen and ink, etc); but a wireless controller allows it to be selectively illuminated to provide interactivity (e.g. to provide tips on homework problems).

Make: an open source hardware, Arduino-powered, 3D-printed wire-bending machine

How To Mechatronics has pulled together detailed instructions and a great video explaining how to make an Arduino-powered, 3D-printed wire-bending machine whose gears can create arbitrary vector images out of precision-bent continuous lengths of wire. (via Beyond the Beyond) Read the rest

Kickstarting the Makerphone: an open-source hardware phone kit, programmable with python and Scratch

Circuitmess's fully funded Makerphone kickstarter is raising money to produce open source hardware smartphone kits to teach kids (and grownups) everything from soldering to programming. Read the rest

This year's Electromagnetic Field hacker campout demonstrated the awesome power of DIY cellphones and DIY stingrays

Every year, security researchers, hardware hackers and other deep geeks from around the world converge on an English nature reserve for Electromagnetic Field, a hacker campout where participants show off and discuss their research and creations. Read the rest

Making an LED you blow out like a candle, without any additional sensors

LEDs are diodes (that's what the D stands for) and diodes are sensitive to voltage drops: when you blow on an LED, you make it ever so slightly cooler, and that causes an infinitesimal, but detectable voltage drop. Read the rest

A next-gen, multi-switch Useless Machine that unswitches your switches in order

Coffeeman 500's Useless Box - Multi Switch project is an open-source hardware project that's an ambitious variant on the beloved "Useless Machine" -- 2010, 2010 (Lego)), 2010 Political edition), 2011 (HOWTO), 2012 (politics), 2013 (fancy), 2013 (advanced) (vs human), 2016 (most useless), 2017 (vs twisty vase).

Karaoke casemod: it's surprisingly easy to hook up a karaoke machine's CRT to a Raspberry Pi

Brett writes, "As a critique of the IoT buzz, I hacked a portable karaoke machine, stuffed a Raspberry Pi in it, connected it to the internet, and installed Docker on it." (tl;dr: he needed a portable CRT for an installation, found one embedded in a thrift-store karaoke machine, and got it wired up to the Raspi on the first try and discovered it made a perfect and delightful casemod).

The Cyberdeck: a homebrew, 3D printed cyberspace deck

A small but vital genre of homebrew portable computers is the "cyberspace deck," in which hackers create DIY, special-purpose computers inspired by the ICE-breaking console-cowboy decks of William Gibson's Sprawl trilogy (Neuromancer, Count Zero, Mona Lisa Overdrive). Read the rest

Four Thieves Vinegar Collective: DIY epipens were just the start, now it's home bioreactors to thwart Big Pharma's price-gouging

When last we met the Four Thieves Vinegar collective -- a group of anarchist scientists who combine free/open chemistry with open source hardware in response to shkrelic gouging by pharma companies -- they were announcing the epipencil, a $30 DIY alternative to the Epipen, Mylan's poster-child for price-gouging and profiteering on human misery.

Homebiogas: easy, clean, climate-friendly way to heat and power your home with garbage

Yesterday, I saw a demo of the Homebiogas bioreactor: it's essentially an artificial stomach that uses colonies of microbes to digest your home food waste (it can do poop, too, but people tend to be squeamish about this), providing enough clean-burning biogas to cook your next meal, heat your house, or run a generator -- what's left behind is excellent fertilizer.

Kickstarting an open digital microscope kit for public-spirited citizen science

The Community Microscope is a fully-funded, crowdfunded open source microscope hardware kit built around a digital camera: it costs $39 and snaps together in 15 minutes. Read the rest

Frozen Rat Kidney Shipping Container: The incredibly bounty of the NIH's 3D printables repository

The National Institutes of Health maintain a 3D Print Exchange, a kind of miniature Thingiverse for open-licensed, 3D printable objects for teaching and practicing public health. Read the rest

Astounding t-shirt art, created by marker-wielding open source hardware plotters

Evil Mad Scientist Labs sell a bunch of cool open source hardware kits for making plotters -- basically, a very precise robot arm that draws with whatever pen or marker you screw into its grip. There's the Eggbot (for drawing on curved surfaces like eggs, balloons and balls), but there's also the Axidraw, which works on flat surfaces. Read the rest

Count your bees with a Raspberry Pi and machine learning

Sure, you worry about your bees, what with colony collapse disorder, but they're hard to count! Read the rest

Innovation should be legal; that's why I'm launching NeTV2

I’d like to share a project I’m working on that could have an impact on your future freedoms in the digital age. It’s an open video development board I call NeTV2.

MIT students create and circulate open source, covert RFID rings to subvert campus tracking system

A reader writes, "A couple years ago MIT changed their dorm security/student tracking policy. They hired security contractors to work in dorms and required everyone to tap their RFID cards upon entry (no vouching for friends/guests). Most students complied. Some moved out. Some got in trouble ;)" Read the rest

Meshing, rugged, free/open wifi routers for refugee camps

Meshpoint is a Croatian open source hardware company that turns out rugged, meshing, battery-powered wifi hotspots that get their backhaul from cellular networks; they're based on the widely used Open WRT free/open wifi routing software, and use open source hardware designs that are intended to stand up to punishing field conditions like those found in refugee camps.
