The Virtual Haircut That Could Change the World | Wired Design. A Little Printer. “We’re way past the time that technology and its processes could be made understandable by an array of indicator lights, or even a desktop GUI, which worked really well for a long while,” says Webb. On or about the 14th of February, 2013, the hair on Little Printers’ faces began to grow.
Stick with us. This is about the future of the Internet of Things. Little Printer is a creation of BERG, a design consultancy based in London. Little Printer is a connected appliance. Here’s how Little Printer works. Frivolous Applications of Big Ideas If you are having trouble understanding why you’d want one of these in your home, you are not alone. “We’ve had a long interest in what happens when the Internet is no longer trapped behind glass.” Little Printer is a niche product. The context in which you need to think about Little Printer is a society on the brink of almost completely wiring itself up with sensors and networks.

Chip Basics For our experiments, we'll use a couple basic chips: 40106 Hex Inverting Schmitt Trigger: This chip contains 6 individual Schmitt triggers. A Schmitt trigger is a comparator circuit that incorporates positive feedback. What this means is that when a high signal (positive voltage defined as '1') is applied to the input pin, the output pin generates a low signal (ground voltage defined as '0). This simple circuit can be connected to a resistor/capacitor pair to rapidly turn on an off. When the frequency of this on/off conversion is in the audible range, we hear a square-wave tone. 4040 Binary Counter/Divider: This simple logic chip takes an input square wave and generates oscillations at 8 outputs with a frequency related to the input frequency. 4051 Eight Channel Analog Multiplexor/Demultiplexor: The voltage status of the three address pins A, B and C determines which of the eight channels presents its voltage to the common connection pin.
Let's Build Something Fun. Ten Tips for New Raspberry Pi Owners. Merry Christmas, makers! We’re guessing a lot of you found Raspberry Pis under the tree this morning and are eager to start hacking around with it. Getting Started with Raspberry Pi, which I co-authored with Shawn Wallace, will be shipping very soon and is available for pre-order now. In the meantime, we’ve compiled a list of a few of our favorite quick tips that may come in handy as you explore the platform. Some of these might be old hat to experienced Linux users, but who knows, you might also learn something new. And if you have any favorite Raspberry Pi tips that you’d like to add, we want to hear them!
Please share them in the comments below. Command line completion You don’t have to laboriously type out long paths, filenames, and commands. Command history Bash also keeps a history of the commands you type. Jumping to the beginning or end of a command If you want to jump to the beginning of a command you’ve typed (for instance, if you’ve miskeyed something), type Control-A. Related.

JamStik portable MIDI guitar lets you play and learn on the iPad wirelessly.
We heard from our friends over at TechCrunch (thanks, John Biggs!) That a company called Zivix has been showing off a cool little MIDI guitar at CES, so here it is! Dubbed the JamStik, this digital instrument serves the same purpose as the already-available You Rock, except this one comes with real guitar strings, works wirelessly over WiFi, features a lower latency (under 10ms instead of about 20ms, according to Zivix's lab test), and it also has a shorter neck plus a much smaller body for the sake of portability -- even for some casual plucking on the plane.
The JamStik also supports string bending thanks to the way it detects finger movement on the neck -- the rows of infrared lights and sensors under the strings make the magic happen.

So this week I've been experimenting making PCB's using a great freeware package for windows ExpressPCB I'm using the toner transfer method, laser printing onto glossy paper and then heat transfering the toner onto the copper clad board (ironing the back of the paper on the hottest setting!) I'm then soaking off the paper and etching the boards using Ferric Chloride. Here's a board thats the result of this process. The board above is for a simple 4 - 1 passive mono mixer which is based on the ones I've made for my CMOS synth stuff.
And another shot of her getting tested... So I plan to make a couple of these for friends and maybe some more for myself, I realised that this board could also be built up with full size pots and audio connectors (jack/phono etc) and stuck in an enclosure so I am going to release a pdf of the board for if people wanted to build there own but I need to do a bit of documentation first.
