Recently I built some sound reactive LEDs to put into my gaming computer:
I like to take pictures of lightning and stars, but the only problem is that these require relatively long exposure times (15 sec – 2 min) so holding down the shutter button for that long causes some camera shake from my hand. Therefore, I decided to build a remote to control my camera so that I don’t have to actually touch the camera itself. Here’s what the remote looks like:
The bottom button auto-focuses the camera (although, since lightning and astrophotos are in the dark, manual focus is normally used). The middle red button takes a picture for whatever length is set on the camera. It’s just like pressing the shutter button. The toggle switch on the top acts like holding down the shutter button. If a shutter time is set on the camera, then it will continuously take pictures for the set time. Otherwise, if the camera is set to “bulb” mode, it will lock the shutter open for as long as the switch is toggled. Here’s a picture I took using the remote:
