![]() ![]() The code i run on my controller as of now is up there in a hex file along with the main c file and its dependencies. I have provided some applications in step 13. The only major limitation of the design currently is that it works only with IR interfaces, it would be fairly simple to modify the software and hardware to output via mini-USB or whatever sort of interface is required. You could even link the circuit up to another controller and provided it can give you a logical output, thus you can trigger from it. By simply monitoring a voltage level, your trigger could be light based (LDR), sound based (microphone or ultrasound), temperature based (thermistor) or even a simple potentiometer. On the face of it this is a boring statement, but once you begin to understand the implications it becomes very powerful. If your sensor generates an output voltage between 0 and 5V, you can use it to trigger your camera! Most importantly, in these tight times, the cost is lower than alternative models (some people have produced kits doing this kind of thing, but they cost a fortune see links). But what im going to show you is that its possible to construct a circuit that will give you consistent results time and time again. Ok, 1 and 2 are fine for messing around and can yield some very good pictures. Buy a dedicated trigger controller that has some kind of audio/light sensor to take the picture at your command Improved trial and error you black out the room, put your camera on bulb (open shutter) and fire a flash at the right timeģ. Trial and error you try to take the picture at the right momentĢ. ![]() There are a variety of methods for doing this:ġ. You want to take a picture of something quite fast (limited currently by the lag on your shutter, for me 6ms). Where my implementation differs from most intervalometers and diy remotes is that it allows for a lot of customisation and modularity, is compatible with both Nikon/Canon (and likely others later) and combines the ability to take a picture on a particular trigger. I then found out (somewhat embarrassedly, because i thought i'd had a massive brain wave) that this has been done and there are even a couple of instructables on the topic. I thought, hey, it's just an IR LED isn't it? Why can't i replicate it and make my own remote with a built in delay? I was doing an 8 second interval for around 1000 shots. I had the idea for this after sitting outside in the cold clicking my remote control for hours. Uses IR so is both wireless and doesn't damage your camera Included sensor designs - light, sound (many more possible!)Ĭompatible with Nikon/Canon (coded), potential support (untested) for Olympus/Pentax Triggered shot (trigger from external sensor) mode with variable conditions I've gone through how to breadboard it since the process is very similar and allows for correcting mistakes before you make the design permanent! Features: It will be a simple case of transferring the design to a stripboard and adding the LCD for most people. I've provided schematics and full code so you can always just copy it. Think of this as a lesson in camera controller design. This started off as a full blown tutorial, but due to some unexpected constraints i encountered later on, it may be more of a guide as to how to accomplish various things - i'll often leave you the choice on how you could do things which i think is a better way of doing things than just blindly saying "you must do this". Certainly this will also work (with a bit of modification) with camera hacks where you can wire up logical outputs to camera trigger terminals. This instructable is mainly for the benefit of SLR users looking to get a bit more mileage out of their cameras, however if there are any point and shoots with IR interfaces, you might find this interesting. Update: First Prize =D, thanks for voting and/or rating! Update: new photos of the laser trigger in action! Update: featured on hackaday! /3/a-different-breed-of-camera-controllers/ This is an entry into the Digital Days competition so if you find it useful, please rate/vote/comment favourably! If you reallly like it and are a stumbler, hit "i like it!" :) The schematic is correct, but the component list was wrong - updated. Introduction Ever fancied building your own camera controller? IMPORTANT NOTE: Capacitors for the MAX619 are 470n or 0.47u. ![]()
