Arduino High Speed Photography Trigger

Arduino High Speed Photography Trigger

High Speed Photography using the Arduino Using a laser and sensor to create an electronic trip wire, this high tech photographer used the Arduino programmer to capture high speed pictures of liquid droplets, creating this outstanding collection of photographs.� His photos can be seen below, and you can learn how to make your own with the full tutorial and project code.� Pick up some low priced lasers and other project supplies in our store.

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

Create Techno with a Laser Harp Ever wanted to make your own techno music, but are tired of the standard midi controller? Well, you could build a harp (of all instruments) out of lasers and then play it by breaking the beams of light. See how it’s done. The harp is connected to the software synthesizer, the TAOS sensor array sits on the floor in its own stand. The array above the harp is just made up of mirrors for added p’zazz. How it works: Basically an Arduino connects to a 12-bit DAC chip (TLV5618) using the SPI 3 wire interface. Buy your next laser from the HacknMod Store. DIY camera motion control Hows about moving your HF100 like a pro?DIY camera motion control from Martin Koch on Vimeo. The system consists of a ready-made IGUS DryLin W rail system and a small stepping motor which is controlled by an Arduino interface board. Once the controller program is loaded the system works stand alone. It can be powered by a battery and can be controlled by a simple power switch because the programmed task starts automatically each time the Arduino board is powered on. Slider 1000 mm long Igus DryLin WS 10-80 rail. The Igus order number for a complete system with 1 meter long rail and 150 mm sledge is WK-10-80-15-01, 1000 (the first number is the rail diameter in millimeters, second is the rail width followed by length of sledge, number of sledges and rail length). Official Igus procedure for aligning the carriage (needs to be done once). 1. Controller board Arduino Duemilanove (or Arduino Uno see update below) or Arduino Nano USB I/O controller board.

DIY Mechanical Crank Driven Camera Slider Sliders have caught on in popularity recently with the lightweight DSLR camera explosion. Some say that the effect is overused – perhaps it is, but in my mind adding some slight subtle camera movements to your shot adds a tremendous amount of production value. And when it comes to subtle movement, sliders deliver the most bang for the buck, both in terms of cost and ease of setup and use. I’m going to demonstrate how to add a crank mechanism to an existing slider such as the indieSlider which I’m using here. But like all things on this earth, everything good thing comes with a drawbacks. So I wanted to take the human element out of it – or at least change the way the slider is powered. The following diagram lays out how I mechanized my indiSlider – this technique can be reworked to apply to any slider you have. Here is a PDF version of the schematic Here is a list of specialty parts you’ll need: Tools you’ll need: Drilling the Screw holes in the carriage for the timing belt

DIY belt-driven IGUS camera slider like pocketdolly , but much smaller and lighter. I cut the slider down to 30" and drilled and tapped 1/4-20" holes for legs and the Arca Swiss style quick release plate . I used an extra long quick release plate and drilled 2 holes to keep the slider from twisting when mounted on the tripod. and some round knobs I found on eBay. to keep the slider from sliding around on a smooth surface. A 1/4" hole was drilled in the carriage for the Arca Swiss style ball head . 10-24 holes were drilled and tapped on each side of the carriage to hold small screws around which I was going to wrap the drive belt. The drivetrain is built around a Sherline 2.5" handwheel - this is the only handwheel I could find to fit a 1/4" shaft. Detailed Parts List: Slider:1 x DryLin W1040-A Linear Motion System Feet:2 x Dual Flash Bracket 4 x 1/4-20 ball knobs Tripod / Camera attachment:1 x Arca Swiss compatible quick release plate 1 x Arca Swiss compatible ball head

Controlling a Stepper Motor « cyancdesign [Chris Yanc] One day I tore apart a scanner I owned. I didn't have the power cord for it, so no loss. In fact it became a gain! I started researching, like most things I didn't get it at first. With some really basic Arduino knowledge I started there. Sparkfun is AWESOME too! It's nice, the EasyDriver powers the stepper motor so 12V doesn't have to find its way through the Arduino. This site help me a lot to understand what a stepper motor is, and how to get started. see Tom Igoe's notes on steppers. Or, here is the exact code I used. After that was running, I wanted more control. Some differences from the above code is that there is no longer a progression of speeds automatically. And here is the code for you to try out. I'd like to note that I am a hobbyist, and do not have any actual electrical engineering education other than my own messing around with this stuff.I would assume you'd be able to kinda tell by my stellar diagrams.

StepperUnipolar Learning Examples | Foundations | Hacking | Links This page shows two examples on how to drive a unipolar stepper motor. These motors can be found in old floppy drives and are easy to control. The one we use has 6 connectors of which one is power (VCC) and the other four are used to drive the motor sending synchronous signals. The first example is the basic code to make the motor spin in one direction. The prototyping board has been populated with a 10K potentiomenter that we connect to an analog input, and a ULN2003A driver. Picture of a protoboard supporting the ULN2003A and a potentiometer Example 1: Simple example Example 2: Stepper Unipolar Advanced References In order to work out this example, we have been looking into quite a lot of documentation. - information about the motor we are using - here - basic explanation about steppers - here - good PDF with basic information - here
