faclab: research 3d scanners, printers

http://www.3ders.org/articles/20160128-build-your-own-arduino-powered-desktop-3d-scanner.html


Jan 28, 2016 | By Benedict
Think it’s possible to build a desktop 3D scanner with infinite resolution for just $50? Instructables guru Whitney Potter has done just that, using a Nikon DSLR and an Arduino-powered stepper motor. To capture its high-res scans, Potter’s systems uses photogrammetry—a method of constructing 3D images from a set of partially overlapping 2D photographs. The impressive results have to be seen to be believed.
Naturally, the main caveat of the “3D scanner for $50” claim is its assumption of prior DSLR ownership. Builders of the budget scanner will need their own high quality digital camera—unlikely to be found within that strict budget! Once that small condition is met, however, the process becomes extremely wallet-friendly. The principle of Potter’s system is simple: Why buy a dedicated 3D scanner when, with the right manipulation, your high quality digital camera is capable of producing superior results, and on subjects of all sizes?
The main obstacles faced during photogrammetry are photograph quality and spacing. Each photo must be perfectly focused and exposed, and must be spaced around the object to capture its every feature. There must be sufficient overlap between photos so the rendering software knows where each shot belongs. Getting this spacing right can be achieved with some practice on large subjects, but is incredibly difficult with small objects. This is where Potter’s Arduino-powered stepper motor comes in.
The DIY 3D scanner uses a stepper motor controlled by an Arduino board to turn the scanned object by a fixed amount, before an LED triggers the camera’s wireless sensor, setting off the shutter. This process is repeated until photos have been collected from all angles, allowing one’s photogrammetry software to construct an accurate and high resolution 3D image of the subject. There are just five key ingredients to the budget 3D scanner: Arduino, stepper motor driver, stepper motor, IR LED and LCD shield.
Although Potter’s Arduino sketch has been configured to work with Nikon DSLRs, owners of other brands can simply alter a section of the code to suit their own model. Potter has used Sebastian Setz’s Multi Camera IR Control library, so the scanner will work with virtually any brand of camera with an IR remote. When the code is in place, the subject needs to be well-lit so the camera can capture all of its precise details. The captured set of photos can then be processed using photogrammetry software. Potter recommends Agisoft Photoscan ($180), Autodesk Memento or Autodesk 123D Catch (budget option).
Potter’s handy guide demonstrates an innovative method for 3D scanning on a budget—using resources at most people’s disposal. Could DIY photogrammetry be the future of desktop 3D scanning? Watch out, 3D scanner manufacturers!

photogrammetry system
Jul 28, 2016 | By Andre
For some time now 3D scanning, especially when it relates to recreating the intricacies of the human face, has been limited in some ways. Whether its low-resolution capture or lengthy waits or cumbersome post-processing, there aren't many examples of a device that can capture all the details of the human face (and beyond) in just four seconds. The Royal Academy of Arts in London has recently begun experimenting with a photogrammetry system that takes 96 photos in rapid succession via an eight camera system. These images can then be processed into a digital 3D model, replicating every feature of the face in intricate detail. The results are something some of history's greatest artists would be jealous of no doubt.

Course Work

Introduction:

FacLab - Gennevilliers

What do we think of the FacLab experience?
The answer to this is multifold, as I review the sequences in my mind, they bring back very good memories.

We all have learnt many many new tech, softwares, ways to make things, the current magic machines and how to use them, apply them to our creative ideas.

Above all, we learnt to work in a team, each with our own personalities and background.

We ate together everyday, chatted, the conviviality is very important to understanding how each person tick; and what they like, their wishes and dreams and battles being fought.

The communal social aspect is very rare once you are outside of your standard schooling environment.  Here at FacLab, we are in a warm and gentle home kitchen environment, you get to relive it again once more.

FacLab is a creativity place, you tinker, you make, people come in and out, you ask a question, somebody may know the answer.  How much more fun it is to be here instead of being alone your own studio!  Its a parallel space where you can go and enjoy a drink or two, meet people.  Learn things, expand yourself, grow, collaborate, join the DIY world movement.  Have an opening to an international FabLab community.  You are plugged in to the world.

As in the movie "Primaire" - which I just saw last week - like that little autistic girl who gets to play an angel instead of a handicap monster, snow flakes sprinkled from above, and God finally realise too, that it takes courage to stay alive, to live, and grow for everybody regardless of age and time.

N.B.:  Another interesting point is, all University trainings are important for self improvement, especially at the end of it, does it help in the next step of the person's development?  After the FacLab experience, it is very clear that, interesting ideas are plenty all around, can you make it happen?  And, after it happens can you sell it?  Circulate it, diffuse it, and enable, grow, make further work possible?  How does a University education link up with the existing job market?  Some University subjects are not necessarily related to employment, work as the next step.  However, is this a valid question to ask vis a vis a subject like "DIY FabLab - numerical fabrication of projects?"?

"Black Night Light" 

group project: Landry, Charlene, Swannjie.

A Black Light tube is installed on the vertical edge of the clamp. 
One movement sensor, and one light sensor are respectively attached at the bottom and the top of the tube.  The adruino board and electric regulators are inserted inside the vertical edge of the clamp.  Electrical wire runs down the rod to an outlet.  

In the evening, you could comfortably get to another area of the house - ie toilet, kitchen etc - without disturbing other people - 

people sleeping - in the same room.

Black Light is a very soft light that reflects only on white and flourescent surfaces, for epileptic people, it is a required, preferred lighting.  As ordinary light is too harsh for their perception.  Therefore this light is designed specially for people with soft lighting needs.


The device could be attached horizontally and vertically anywhere.

There are two versions, the regular "Midnight Black" version and the "Clamp  mobile version.


Clips and Clamps started with a "clip holder" object given as stimulus designed by Loic, inspired by the object, the team began with research with various ways of holding things together; such as velcro, magnets, hooks, elastic... and Landry had the knowledge that Black Lights are necessary for epileptic persons, Charlene wanted to make special boxes with special keys to open and fun games for children, Swannjie wanted to use standard clamping device - as a useful mobile object which could also house the Black Light.  So we had two versions, one fixed with plug in outlet cord, and one mobile, either with batteries or plug in wall outlets.









































"Clamp 2017":
Alternate status of the object
by : Swannjie

This object is a customized clamp originally conceived as a clamping device for a night light mobile use.  There are on the market currently led portable small lights which has an integrated battery, you just charge it up and take it anywhere.  Some have integrated clamping clip device. A handy led lamp on a clip.


"Clamp" is a attachment device which is designed to be used as an adjustable mobile table leg.  It could be used singly as shown here, as a special lighting object.  And it could be used as a discreet customised adjustable height table leg - in this case there will be 4 clamps. 


The legs have an adjustable height feature which makes the table a perfect fit with the user.  Such an adjustable table could be used for guqin performances.


It was designed as a component for carbon fiber guqin instrument.  

The carbon fiber guqin comes in a special carbon fiber transport case, which is the exact dimension of airline baggage.  The four carbon fiber clamp legs are integrated into the case.  

To set up, you open the case, take out the carbon fiber guqin, take out the 4 clamp legs, and clamp it onto the case (thickness 10cm)  


You have a perfect table for the guqin, including the case as resonance sound box.

Ready for playing/ performance.

Stay tuned for the carbon fiber prototypes coming !

Capteur de mouvement

lecafedugeek.fr



Electronique & Raspberry Pi : détectez les intrus avec le capteur de mouvement PIR


Le capteur de mouvement PIR (Passive Infrared  Sensor) est un senseur électronique qui mesure la lumière infrarouge (IR) rayonnant à partir d’objets dans son champ de vision. Ils sont très souvent utilisés dans les systèmes d’alarmes ou de détection de présence pour leur faible coût (3,80€ chez belectronique.fr) et leur efficacité.
module-detecteur-mouvement-pir
Le fonctionnement d’un capteur PIR n’est pas compliqué à comprendre. Il possède 3 pins : l’alimentation, la masse et le pin data qui va nous intéresser. Par défaut, celui-ci est à l’état bas. Quand le capteur détectera un mouvement cette sortie passera à l’état haut pendant une durée comprise entre 5s et 2min réglable grâce à un des deux petits potentiomètres situés à l’arrière du capteur, l’autre permettant de régler la sensibilité de 3 à 7m.
Pour les détails techniques, ce capteur est basé sur un circuit-integré BISS001, en regardant le datasheet on s’aperçoit que c’est un CI spécialisé pour cette application qu’il opère entre 3 et 5V et qu’il consomme très peu de courant, il est donc idéal pour une utilisation à piles.

Tester un capteur PIR


schema simple_schem

Pour tester un capteur PIR, rien de plus simple : il suffit de l’alimenter entre 3 et 5V (3 piles LR6 font parfaitement l’affaire, pour ma part j’utilise mon alimentation stabilisée de laboratoire et un régulateur 5V) et de brancher une led avec sa résistance en série sur le pin data. En bon prince je vous ai même fait un schéma de ce circuit d’une difficulté remarquable.
Vous pouvez à présent faire vos tests de distance, de réglages de sensibilité et de temps d’activation.
Oui c’est bien beau mais ça va nous servir à quoi en fait ?

On peut imaginer pas mal d’applications :

  • Un allumage automatique d’une lampe quand une personne passe grâce à un relais
  • Un « compte-personnes » en reliant la sortie du capteur sur un compteur logique comme le CD4017
  • Une alarme entièrement personnalisée et personnalisable avec le Raspberry Pi (quelques pistes dans la suite de l’article)
Et que sais-je d’autre ? La seule limite à l’électronique est votre imagination.

Connecter le capteur PIR au Raspberry Pi

J’ai réalisé un petit programme en python avec la librairie RPi.GPIO qui permet d’utiliser le capteur PIR avec un Raspberry Pi et ainsi avoir accès à beaucoup de possibilités (créations d’événements sous certaines conditions, envoi d’un message sur votre téléphone, interface web regroupant des informations sur votre logement quand vous êtes en déplacement…).
Mon programme allume un buzzer quand un mouvement est détecté, le code n’est pas très compliqué mais permet d’appréhender les bases de cette librairie. Il nécessite les droits sudo pour être exécuté.


import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)

pir_pin = 18 #le capteur PIR est connecté au GPIO 18
buzzer_pin = 22 #le buzzer est connecté au GPIO 22

GPIO.setup(pir_pin, GPIO.IN) #configuration en entrée pour le PIR
GPIO.setup(buzzer_pin, GPIO.OUT) #configuration en sortie pour le buzzer

Try:

while True:
    if GPIO.input(pir_pin):
        print("MOUVEMENT DETECTE!")
        GPIO.output(buzzer_pin, True)
    time.sleep(0.5)

except KeyboardInterrut:
 GPIO.cleanup()
