Pixel_K, a French photographer and amateur radio operator, has published instructions on how to make a compact device on Arduino for remote control of DSLR.
The MiniCom remote was made to take pictures of the night sky, so the author added an LCD display to it. All control is with an encoder (a small button that rotates and is pressed). This remote control can even be used with gloves at –20 ° C.
The remote control is equipped with batteries, which are enough for the whole night. The shutter speed is set in the range from 1/100 s to several hours, otherwise the console supports the same standard functions as other similar devices.
The remote control output is implemented as a 3.5 mm audio jack, so you can use various cables to connect digital cameras from different manufacturers to the remote.
Parts List A
case for 4 AA batteries, with a switch, with eBay is used as a case. It is slightly modified by a drill.
Arduino Mini Pro (3.3V, 8MHz)
Adafruit 1.8 ″ LCD
Encoder from Sparkfun
1000 mAh LiPo Battery from Sparkfun
Sparkfun LiPo Micro-USB
Charging Optocoupler CNY74-4 3.5mm
Audio Jack
Plus a pair of 47Ω resistors and a bunch of wires.
Sample assembly diagram: The
result looks like this:
Program code and a modified library for the LCD:
