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
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
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
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).

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).

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
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.

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.

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