Yeah, just a small problem.... She is going to be in the photograph with me....
This is a double self-portrait project.
I thought about getting a short pneumatic type, cut it, and pump it up with a small air pump. I can rig up a garage door clicker and receiver, hook it up to a pump and do it that way. I think it's better than using a solenoid or servo as vibration won't transfer to the camera body.
I really wanted to avoid DIY though.
