DIY：延时摄影的红外遥控器（Nikon D70）
An IR Remote Control of Time Lapse Shooting for Nikon D70
Nikon D70相机没有延时摄影功能，但有红外遥控器可控制快门。我在2009年左右做了个红外遥控器。最近把它加了个插口，把市场上能买到的延时器接到这个插口上，这样Nikon D70就可以延时摄影了。
Nikon D70 does not have a function of time lapse shooting but the shutter for Nikon D70 can be controlled by a Nikon IR remote control. In this project, I made an IR remote control for Nikon D70. This IR signal control could be released either by a bush-on button or by an input from an intervalometer.
On the video, the green LED light in the intervalometer is for focus, the red LED light is for shutter release. the time interval is 10 seconds.
Tools used:
1. IR remote control: made for Nikon D70, using a pic mictrocontroller.
2. Intervalometer: commercially available, such as Jintu for Canon 60D, Pentax K110D (with a 2.5 mm male-male stereo cable).
3. If you already have an intervalometer designed for other cameras, such as for Nikon D200, D300, you could buy a 2.5 mm male-male stereo cable or make one yourself, with your existing intervalometer.

焊了一个2.5 mm male-male stereo cable:
三张间隔10秒的照片。时间分别为6小时01分54秒，6小时02分05秒，6小时02分17秒（我老早就注意到这些市场上的延时器不准了，今天没想到10秒钟就能差1秒， Nikon D200， D300s上的延时器使用20天也不会差2-3秒）。
