Trigger Your DSLR Wirelessly With Smartphone and ESP8266 Wi-fi Module

It will only cost you a few bucks (pounds, euros or whatever) and require basic soldering skills to wirelessly trigger your DSLR camera from any smartphone, including Self-timer and Intervalometer modes.

Tested on a Canon DSLR, but it should work with any camera with built-in shutter switch terminal (cf. http://www.doc-diy.net/photo/remote_pinout/)
