On Adafruit Learning System there are a lot of cool tutorials and this particular one is based on the Arduino Micro used to upcycles old Next keyboards:
Ladyada and pt had an old NeXT keyboard with a strong desire to get it running on a modern computer. These keyboards are durable, super clicky, and very satisfying to use! However, they are very old designs, specifically made for NeXT hardware, pre-ADB and pre-USB! That means you can’t just plug the keyboard into an ADB or PS/2 port or PS/2 to USB converter (even though it looks similar). In fact, I have no idea what the protocol or pinout is named, so we’ll just call it “non-ADB NeXT Keyboard”
Click and follow the steps to make your own.
In his blog, Marc from Robot Dialogs presents a very nice hack involving a IBM Selectric II typewriter: by means of an Arduino board and several solenoids, the typewriter can be successfully connected to a computer to emulate a vintage teletype.
The complete story can be found here, together with several videos about its development.

Everyday, a lot of spam inevitably arrives to our mailboxes, forcing us to lose time in discerning fake emails from good ones, so everyone agrees on saying that spam is frustrating and completely useless.
This is almost true, since Varvara Guljajeva and Mar Canet Sola have taken advantage of spam coming from the Internet (more specifically, those messages “donated” by Eindhoven people) to make a very creative art project: first, they have recycled spam to algoritmically create poetry and, then, they have sent the result to a properly Arduino-hacked knitting machine (Arduino has been used to emulate the typing of the commands required to load the pattern).
From the authors:
Concerning the concept, we are interested in bringing together digital culture and traditional handicraft. To be more specific, the idea is to experiment with the form and meaning of SPAM. We turn SPAM into a romantic, funny or even sarcastic poetry and present it in unusual tangible form as knitted garment. To be more specific, we call final result dysfunctional wearable, because it reminds a sweater but is not really a one. Like SPAM, our dysfunctional wearable does not have a purpose.
The result is really impressive and it has been presented at two exhibitions, at Eindhoven and Malmö. Several pictures of the events can be found here. More information about the project can be found at Mar and Varvara‘s homepages.
En él nos descubre el nuevo módulo 3G para Arduino de Cooking Hacks con el que podremos construir una divertida alarma que nos enviará la foto de nuestro intruso directamente a nuestro correo, además de avisarnos por un mensaje sms a nuestro teléfono móvil sin necesidad de tener conectado nuestro Arduino a internet constantemente, pues lo hace todo a través de la red móvil.
Vamos a construirnos una alarma totalmente casera, a través del sensor de ultrasonidos, escanearemos continuamente el espacio situado enfrente suyo con un radio aproximado de 30º, cuando algún objeto o persona se sitúe en su campo de actuación a una distancia inferior a la que establezcamos, haremos sonar una alarma, tomaremos una fotografía, el Led RGB que antes estaba verde, pasará a color azul y daremos 10 segundos para poder desactivar la alarma a través de nuestro teclado matricial, si la desactivamos, volverá de nuevo a escanear el campo, pero si no!! Reproducirá un sonido contundente y se dispondrá a mandarnos un sms a nuestro teléfono móvil y la fotografía a nuestro correo electrónico.
A weekend project by Adafruit to print announcements and discount coupons from the internet.
This project uses an Arduino Uno, an ethernet shield, a thermal printer (aka receipt printer) and a Staples easy button to print out the current discount percentages available at the tkts times square booth for Broadway shows.
A beautiful tutorial accompanies the project.
The Twittertape Machine prototype from Adam Vaughan connects to his Twitter account via Ethernet, checks for updates twice every minute, and prints out a hard copy of any new Tweets without the need for printer ink.
Vaughan told us that the idea for the Twittertape Machine was born of a desire to have the kind of old stock ticker seen in movies sitting on his desk. After a lukewarm reception to his pitch from friends, he decided to make his dream a reality. Rather than sacrifice a rare original (like the Edison Universal Stock Ticker used for Ames Bielenberg’s Spring Break project), he opted to build his own replica version from some old brass clock movements, a wooden plinth and a glass dome found online.
It is powered by two AC adapters and is controlled by a network-enabled Arduino-style microcontroller running custom code in the base. The board checks Vaughan’s Twitter account every 30 seconds for new Tweets.
The little thermal printer hidden at the base prints the tweets on a cut-down thermal paper. An awesome product in an awesome demand!
Il prossimo week-end a Torino si terrà un workshop gratuito di Arduino (un kit opzionale potrà essere comprato per partecipare qualora non disponeste dei materiali elencati) sul circuit bending e la generazione di suoni con la scheda.
Un workshop di tre giorni per smontare riciclare e far suonare vecchi strumenti elettronici, creare una digital toys orchesta e sfilare in parata a Paratissima.
Il circuit Bending è una pratica molto diffusa tra gli sperimentatori musicali. Soprattutto sulla scena della musica elettronica sono sempre più frequenti gli artisti che si creano controller o addirittura strumenti musicali personalizzati.
Nel workshop saranno coinvolte diverse discipline: toy hacking, riciclo elettronico, elettronica di base, sintesi sonora, programmazione ad oggetti e faremo largo uso di Arduino per comandare i nuovi strumenti.
Il workshop è gratuito, a carico dei partecipanti il costo dei materiali e l’acquisto del kit-workshop.

[Riccardo Giraldi] posted a nice project controlling a slot car race from a Mindwave headset (=> your brain waves).
From B-Reel’s secret laboratory comes a brain-bending experimental project utilising a number of cutting edge tech tools. B-Reel’s UK creative director Riccardo Giraldi led the development of the project, and you can view the explanatory video here, as well as some of the creative musings in a write up below. [...] There are few commercial devices that claim to safely read your brain signals. We ended up choosing the Mindwave headset from Neurosky for this experiment because of its unobtrusive design and its affordable price.
Pinball machine will automatically power up at the preset time each day and then resets to display the current time, the year, the time the alarm is set for and the date month/day. Then as long as the GPS has a signal the time will update once a minute for the rest of the day. At the time you would like to go to bed the Arduino will cut power to the game and it will remain off until the alarm time. Should you have a power failure in the night the machine will not lose it’s settings. If power is restored prior to the alarm time the machine will wake up as normal, otherwise the machine will wake up once power is restored.
If the game is powered on because it is not yet bed time and it is after the alarm time then at 12am, 1am or 1pm the game will do a full reset. This makes sure the clock hasn’t gotten off due to a stuck score reel, keeps the time in a 12 hour format and keeps the date display up to date.
