Multi proyectos 0084

Finally, we have these in production! Took a lot longer than expected, due to some other urgent projects with Tangible Interaction, and Maker Faire. Anyway they’re here and I think they look great.

The Centipede Shield adds 64 general purpose digital I/O to your Arduino. By “general purpose I/O” I mean that each pin can be individually configured as an input or an output, just like the normal digital pins on an Arduino. We’ve alsocooked up a library that makes it easy to talk to the Centipede Shield; the syntax very similar to the normal Arduino digital pin commands.

Leather work, copper tubing, small easy to use package. Now that is a beautifulArduino Watch. [Matthew Garten] has retrofitted his old Arduino Watch and given us the details that we crave.

Here at the Transistor, we love the Arduino platform, so we decided to make our own Arduino Clone. The Minimalist Arduino is designed for use in permanent or custom circuits on solderless breadboards, stripboard, or custom PCBs. It contains only the bare minimum parts required for building the Arduino platform. The schematic for the board can be downloaded here (pdf).Please read all instructions on this page before assembly. The parts list is as follows, with linked manufacturer datasheets when available:

(1) ATMega328P
(1) 28-Pin DIP Socket
(1) LM7805 1A 5V Positive Voltage Regulator
(1) 16.000MHz Clock Crystal
(2) 22pF Capacitor
(2) 10uF Capacitor
(2) 100nF Capacitor
(1) 10kOhm Resistor
(2) 150 Ohm Resistor
(2) Green 3mm LED

Parmi la centaine de commentaires provoqués par notre récent article Pourquoi je n’achèterai pas un iPad, on a pu noter une opposition franche entre ceux qui pensaient qu’il était important, voire fondamental, d’avoir la possibilité « d’ouvrir le capot » logiciel et matériel de la bête, et ceux qui n’y voyaient qu’une lubie de geeks passéistes et rétrogrades.Or aujourd’hui nous allons justement évoquer un drôle d’objet qui accepte d’autant plus volontiers de semettre à nu qu’il sait que c’est sa principale qualité aux yeux de son enthousiaste et créative communauté.

Nous vous suggérons également cette excellente interview de Alexandra Deschamps-Sonsino, réalisée par Hubert Guillaud pour InternetActu, dont voici quelques larges extraits :

Depuis la révolution industrielle, on a beaucoup créé de dépendances aux produits déjà fabriqués, déjà organisés. Le mouvement DIY (Do It Yourself, Faites-le vous-mêmes) qui se développe depuis 2 ans, réunit une communauté qui ne veut plus accepter des produits tout finis, tout cuits. Cette nouvelle vague de hackers (bidouilleurs) essaye de regarder ce qu’il y a l’intérieur, alors que les conditions d’utilisation n’encouragent pas les gens à regarder ce qu’il y a l’intérieur de ce qu’ils achètent. (…) Le DIY devient un outil pour la microproduction, permettant à chacun de créer son propre business, de fabriquer 20 exemplaires et de voir ce qu’il se passe. Le DIY est finalement important pour sortir du carcan de la mégaproduction. Avant, il fallait un grand marché potentiel pour lancer un produit. Avec l’internet et des plateformes comme Arduino, chacun a accès à sa micro production.

Regular reader [Osgeld] built a 1024 LED display matrix. This is a proof-of-concept design and he admittedly has overloaded the components. Most notably, the 595 shift registers (featured over the weekend) are sourcing too much current if all eight pins are active. That’s easy enough to fix in the next design by moving up to cascading LED drivers. Instead of soldering every connection in the display, [Osgeld] soldered the components in place and then used wire wrapping to make the point-to-point connections. This must have saved him a ton of time and frustration. We can’t wait to see what comes out of this first prototype.

During the last two days I have been conducting a workshop for kids on the topic of electronics. The idea of this workshop is to warm up for a course to come later in July when we will be playing around with robots. I have the task of designing 2 or 3 different models of robots together with the documentation needed to run the course.

‘NIKE Levitation’

To me the shoes have a very pure function. Supporting, cushioning and softening the inevitable fall back down to earth. It was this relationship with gravity that gave me my starting point. I asked what would happen if the shoes didn’t have to fall back down to earth? What if they never touched the ground? How would their function change? I imagined them moving away from impact cushioning and towards a kind of spectacle. So this is what I decided
to make happen.

Actually making it happen was very challenging. After experimenting (and failing) with many different systems and methods, I finally settled on a system comprising an electromagnet and feedback system, at the heart of which is an Arduino micro controller.

Here’s the source code for the Arduino + PING))) + 7-Segment Shield ultrasonic distance sensor project I build for this video. It is the progenitor of my Arduino Nerf sentry gun code, which I’ll be posting soon. Warning: my code gets the job done, but isn’t elegant.

Basically in short, we’re creating an open source laser cutter.

We have been doing the research for the last few months and believe we  have all the specs to make it happen… Now we just need the capital  to do it. Much like the open multitouch system of ’07/’08 we did, I believe if we can get the same attention, we can get the community to make it happen.

I want open source laser cutters to become a reality and an inundated fab piece for artist/designers/hackers. As you know from ITP, people can do amazing things if they just had the access to the equipment so  we’re trying to make that happen and happen now.
