If you’re looking for more control than the average shutter release cable, then you should check out this DIY Bluetooth shutter release from YouTuber Scott Wallace. Using an Arduino Uno, BlueSmirf Bluetooth transceiver, and some perfboard, Scott fashioned a device capable of accepting commands over the air from his Android handset. [via nikonrumors]

The camera I’m using is a Nikon D90, but this same controller would work on all Nikons that have the same shutter release/GPS port as the D90. Additionally, I’ve read about Canon and Sony DSLRs also having a wired shutter-release port that operates in the same way, you’d just have to find the pin-out of those ports and make your own connector .

On the Android side, right now I’m using SENA BTerm as the Bluetooth terminal. This isn’t a long term solution, but for now is a proof-of-concept that camera control from the phone is possible.
