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.

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.

cnet With more people packing smartphones and mobile hot spots, a camera with Wi-Fi gives you the control, flexibility, and quality of a dedicated camera with the capability to back up to a cloud service, computer, or mobile device while you shoot, or share shots online without offloading to a computer first. However, while many new point-and-shoots have Wi-Fi built in, fewer dSLRs and mirrorless interchangeable lens cameras (ILC) have wireless connectivity. Also, if you have a camera that's only a year or two old, chances are you're not ready to run out and buy a new one just to add some wireless functionality to your shooting experience. There are ways to add wireless features to your current camera of choice, though. Some are just for image transfers or for remote control with a smartphone or tablet, while others can do both and more.

Interrupts, the easy way Many folks starting out in microcontrollers do not know what interrupts are, or are intimidated by them. Today I hope to shed some light on this easy to use, and useful function. There are two ways to detect if an event has happened, polling, and interrupts. If you are expecting someone to come to your front door, you can get up every few minutes to look out the window (polling), or you can be busy cleaning your house until the doorbell rings (interrupts). Day by Day: Nikon D700 - DIY GPS Project I built a GPS unit for my Nikon D700 over the last couple of weeks. I have been testing it all this week. I came across this design by Rick Wargo while looking for DIY GPS solution for my Nikon D700 that was simple and cheap to build. ABC - Arduino Basic Connections - PighiXXX ABC – Arduino Basic Connections Just about everything you every wanted to know about how interface your Arduino to a wide selection of input and output devices! All cards are now divided in sets (3 cards each). For every card there’s a revision number.

How To DIY An Uber High Speed Trigger Michael Ross is not only a talented photographer, he is also somewhat of a maker. If you don’t believe me check his Digital Light Wand and Programmable Orb Tool tutorials. His latest endeavor is a super functional Arduino based high speed trigger. Happy Hallow-uino! Celebrate October 31st Maker style Let’s face it, Halloween is arguably one of, if not, the best night to be a Maker — a celebration full of carving, candy consumption, and of course, DIY props and costumery. To pay homage to All Hallows’ Eve, we decided to compile a list of a few Atmel powered tricks, which surely deserve treats! Tired of having to greet those trick-or-treaters personally? Powered by an Arduino Duemilanove (ATmega168), this talking skeleton will take care of all that mumbo jumbo for you, with a variety of your own prerecorded phrases. Muahahahaha!

Micro-Manager Download the most recent version (1.4) from our website. Also check out our ScreenCast for a quick tour on getting started. You have a choice of many commercial packages available, too many, perhaps. Some are produced by microscope or camera manufacturers, others by third parties but they all suffer from the same problems: lack of flexibility and proprietary drivers... With the help of users world-wide Micro-Manager has been developed into a professional Microscopy software able to connect to a huge list of devices and effortlessly perform laborious acquisitions.

Digital camera control using Arduino USB Host Shield. Part 2 – Canon EOS Cameras. By Oleg Mazurov New version of PTP Library for Arduino USB Host Shield has been posted on GitHub. In this version, PTP::Task() has been completely rewritten to provide for non-blocking state machine-type execution. Poorman's oscilloscope (with Arduino + Processing) This software allows you to get a visual representation of an analog signal using Arduino and Processing. The resolution is 10 bits, which is good, but the frequency is a lot lower than that of a real oscilloscope but it is still pretty useful. It works by sending values read from the Arduino board (pin 0) to Processing through serial communication. Alternative Arduino oscilloscope projects Arduinoscope (was inspired by our oscilloscope)Lxardoscope (non-java alternative)
