Triggering a Camera’s Flash with Sound and Light

Triggering a Camera’s Flash with Sound and Light
Update: Check out my latest Camera Axe project for a much more robust device that handles this or my store where I sell the Camera Axe. For those just wanting to see the pretty pictures, click here. This article focuses on making the sensors used to trigger a camera’s flash using a microphone or a cheap laser pointer. Since I’ve already described how to do the actual firing of a camera’s flash here I won’t focus on that part of this project today. There are a lot of places on the web that describe how to trigger a flash with an electrical circuit, but I feel that using a microcontroller like Arduino offers big benefits. For instance you can easily add new sensors, or even run multiple sensors at once. Now let’s talk about why we’re triggering the flash. Most SLR and DSLR cameras let you attach a cable to trigger the camera directly. When I’m using this flash trigger I work in a dim room and set my shutter speed to 10 seconds. Laser Sensor Here’s the circuit. Sound Sensor Flash Trigger Related:  ArduinoProjet de réalisation

Guilherme Martins : PAPERduino’s design This is a fully functional version of the Arduino. We eliminated the PCB and use paper and cardboard as support and the result is.. the PAPERduino :D This is the the first version of the layout design, next we will try more designs, and another materials. There is no USB direct connection, so to program the paperduino you will need some kind of FTDI cable or adapter. Download PDF Components list: 1 x 7805 Voltage regulator 2 x LEDs (different colors) 2 x 560 Ohm resistors (between 220oHm and 1K) 1 x 10k Ohm resistor 2 x 100 uF capacitors 1x 16 MHz clock crystal 2 x 22 pF capacitors 1 x 0.01 uF capacitor 1 x button 1 x Atmel ATMega168 1 x socket 28 pin Female and Male headers Instructions: Use a needle to puncture the holes for your components. Don’t rush, place one component after another and do all the solder work carefully. Follow the connection lines. And this should be the final look of your paperduino connections. PAPERduino for ALL and more..

DIY High Impedance Preamplifier w/2N3904 Arduino Camera Axe 5 Shield This is the first Camera Axe shield, but it leverages the lessons learned from the previous four generations of Camera Axe hardware. The word “shield” describes a board that plugs into the Arduino board. The standard Camera Axe 5, which will be released in the next few months, will have a lot of difficult to solder surface mount components. There are hundreds of thousands of people who have Arduino boards. The both versions of the Camera Axe 5 will use 100% the same software and will both have the same capabilities. Here are some improvements this design has over the Camera Axe 4: Lower cost than the Camera Axe 4 kit.Sensor ports can now have two data lines per port. Useful links: As always here are the schematics and Eagle PCB files. Permalink Camera Axe 4 After six months of work, the fourth version of the Camera Axe is finally ready. Camera Axe Video: Here is a list of improvements from version 3 to version 4 of the Camera Axe. Permalink Projectile Sensor #2 PCBs Results

UobboU Photo Arduino Risultati di ricerca - corbettaluigi - Gmail Arduino Ce projet va vous permettre de réaliser un oscilloscope minimaliste et d'expérimenter la communication série avec un autre logiciel que celui d'Arduino, en l'occurrence, Processing. Un oscilloscope permet de visualiser les variations d'une tension dans le temps, sous forme d'une courbe. Le principe de fonctionnement de ce projet est le suivant : L'Arduino mesure une tension sur une entrée analogique. Il transmet la valeur de cette entrée à l'ordinateur via la communication série à travers le port USB. Précautions L'oscilloscope ainsi réalisé ne sera capable de mesurer que des tensions comprises entre 0 et 5 V. Éléments nécessaires Montage électronique Comme expliqué ci-dessus, le montage se résume à deux fils connectés à l'Arduino, qui vont servir à mesurer un autre montage soumis à une tension variable. Première étape Copiez le programme suivant dans Arduino. /* Ce programme consiste simplement à mesurer l'entrée analogique 0, et à transmettre le résultat via une communication série.

Arduino Analog Pins: Setting Up A Photo Interrupter (or Slotted Optical) For Digital Pins (Part 2) | Utopia Mechanicus As I mentioned in the last post, I finally got my photo interrupter to react under the Arduino, using an Analog pin. Now for my project this was fine, as I had actually allotted one analog pin for this detector, as the digital ones would all be in use. But analog is slow (about 110us), much slower than a digital detect, and I worried this slowness would someday come back and cause problems. So I looked at the circuit I was using, and realized something: the analog output value of 200 was quite low. I was thinking of 255 as the upper limit for analog, but in fact it runs from 0-1023. This means that 200 was about 20% of a full signal, and possibly that was why I couldn’t get a digital reading. So I set about increasing the ‘on’ signal. The pulldown resistor (from ground to the pin, to make ‘0v’ nice and clean) was about 10k; perhaps it was interfering somehow. The next step, now that I had a nice wide range, was to try it on a digital test. So, the moral of the story?

arduino meets processing - PUSHBUTTON The Arduino meets Processing project intends to make it as easy as possible for anyone to explore the world of physical computing. All you need is an Arduino board as well as the Arduino and Processing software, which you can download on their project websites. On this website we explain how to: set up electronic circuits with various kinds of sensors, control and measure the sensors with the Arduino board, send the data to the computer, and use the received values to generate computer graphics with Processing. For all examples you need some basic electronic equipment such as a breadboard, resistors, the sensors, and some wires. The following sensors are dealt with on this website: All examples contain a list of the parts as well as the Arduino and Processing files you need. The Processing files have a DisplayItems class which paints a grid with values, a black or white background. Feel free to play around and have fun exploring the wonderful world of Arduino and Processing!

Piloter des dispositifs sans fil Électronique | Informatique Niveau: Avancé Jonathan Schemoul Montage avec la Leonardo Partie 1: Réception en 433 MHz Vous avez sans doute entendu parler ou vu des détecteurs de fumée, d'ouverture de porte, des télécommandes, des prises murales, etc. sans fil ? Que ce soit les modèles chers que vous trouvez en magasin ou les modèles chinois bon marché, la plupart, s'ils ne sont pas avancés, utilisent la bande de fréquence 433 MHz (n'essayez pas ceux en 315, ils sont illégaux en France). En ce qui concerne ces capteurs en 433 MHz, il se trouve qu'ils utilisent pour la plupart un protocole très simple, introduit par des circuits intégrés chinois à bas coût, les PT2262 côté émission et les PT2272 côté réception (d'autres plus exotiques comme les SC5262 / SC5272, HX2262 / HX2272, EV1527, RT1527, FP1527 ou encore HS1527 peuvent être trouvés et fonctionneront aussi). Regardons de plus près ce que nous avons à disposition : Montage détaillé Niveau détecteurs : Installation de la librairie RC Switch

The 6 Skills Required to be a Good Data Scientist - ANZ Blog Presenting at Teradata Summit 2014 across Australia and New Zealand this week, Teradata CTO Stephen Brobst discussed the skills that are required to be a good data scientist : - Curiosity: Dives into the data head first. - Intuition: Has good business sense and will explore in directions that yield results but is not afraid to fail. - Data Gathering: Knows how to find data and knows how to design experiments to obtain data when it is not available. - Statistics: Understands causality versus correlation, expected value theory, statistical significance etc. This is different from the base math, but covers the understanding of creating a viable sample size, understanding the basis of valid and sound experiments etc. - Analytic Modelling: Uses historical data to predict the future without over-fitting the data. - Communication: Ability to explain the results of data exploration without using math terms. "So, where do you find people like this? - Give them self-provisioning to data.
