Turning a recalled children's unicorn boot into a display for endless product recall notices

Phil Torrone from Adafruit told us about Consumers Should Immediately...: "This uses a live data feed from The United States Consumer Product Safety Commission (USCPSC) to randomly display thousands of products recalled for reasons such as fire, electrocution, entrapment, choking and a variety of other unintended dangers. Every two minutes the embedded screen lists the name of the product, the identified danger, the product manufacturer, and the original recall date. The electronics are enclosed in an actual recalled children’s unicorn boot, along with an embedded rechargeable battery, allowing for an uninterrupted stream of recalled products in any location."

The Pegleg: an implanted, meshing, networked mass-storage device that you sew into your skin

New biohacking from the Four Thieves Vinegar Collective (previously): the Pegleg, a stripped-down Piratebox (previously) based on a Raspberry Pi 0 with needless components removed and an extra wifi card soldered on. Read the rest

How a sex researcher and a cosplaying 3D printing specialist created an open source, orgasm-measuring butt-plug

Nicole Prause is a sex researcher who wanted to design a gender-neutral orgasm-measuring tool that would fit in the anus and detect and measure pelvic contractions but all the buttplugs she tried to modify ("We ordered like 20 of these butt plugs off Amazon, and it messed up my recommendation engine for all time") were designed to be pistoned in and out, and thus had a taper that made it prone to popping out at the moment of orgasm.

Make: a machine-learning toy on open-source hardware

In the latest Adafruit video (previously) the proprietors, Limor "ladyada" Friend and Phil Torrone, explain the basics of machine learning, with particular emphasis on the difference between computing a model (hard) and implementing the model (easy and simple enough to run on relatively low-powered hardware), and then they install and run Tensorflow Light on a small, open-source handheld and teach it to distinguish between someone saying "No" and someone saying "Yes," in just a few minutes. It's an interesting demonstration of the theory that machine learning may be most useful in tiny, embedded, offline processors. (via Beyond the Beyond) Read the rest

Open Insulin: biohackers trying to create a "microbrewery" for insulin as an answer to price-gouging

The Open Insulin project ("a team of Bay Area biohackers working on newer, simpler, less expensive ways to make insulin") is trying to create an open source hardware system for making insulin in small batches, through a process that uses engineered yeast to "produce a modified proinsulin protein, and an enzyme to convert the modified proinsulin into insulin glargine" so that insulin co-ops can produce and test their own insulin for a cost "from ten thousand to a few tens of thousands of dollars."

People with diabetes are scouring the internet for a discontinued insulin pump that can be reprogrammed as an "artificial pancreas"

Since 2014, open source hackers have been perfecting the OpenAPS, an "open artificial pancreas" made by modifying the firmware of discontinued Medtronic insulin pumps, which were discontinued due to the very security flaw that makes them user modifiable (that flaw also leaves them vulnerable to malicious modifications).

A glowing, 3D printed rose that "blooms" when you touch its petals

Daren Schwenke's 3D printed blooming rose embeds a capacitive touch sensor -- a magnetic wire -- in one of the leaves, which trips an Arduino-controlled actuator that changes the rose's lighting and causes the petals -- 3D printed and then shaped over a hot chandelier bulb -- to splay open or fold closed.

Alias: a smart-speaker "parasite" that blocks your speaker's sensors until you activate it

Alias is an open source hardware/free-open firmware "parasite" that fits over your smart speaker's sensors and fills them with white noise; the Alias has its own (non-networked, user-controlled) mic and speaker and when you speak a magic phrase, the Alias temporarily stops the white noise and transmits your commands to the speaker; Alias also lets you specify strings of commands and other useful utilities that restore control over your smart-speaker to you.

A laptop built into a mouse

Electronic Grenade's "'Computer' Mouse" project fits a fully functional computer into a fully functional, 3D printed mouse; the computer is a Raspberry Pi Zero W, with a teeeny leeetle flip out keyboard and a tiny little itsy bitsy flip-out screen. (via Motherboard) Read the rest

Underclocking a baseband chip creates a stealth wifi channel

CNLohr discovered that underclocking the ESP8266 wifi module's Baseband PLL made the wifi channel progressively narrower, until it could not longer be detected by an unmodified wifi receiver -- but a similarly modified wifi module can detect the narrow signal, creating a s00p3r s33kr1t wifi channel; here's sourcecode (which may violate FCC Part 15 rules, so please use responsibly).

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

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).
