ADDING A digital TIMER TO A cord release cam

Here’s a totally non-invasive hack for a traditional Minolta SLR camera. [Robby] wished to add to the choices offered when it pertains to remote shutter release. He ended up building a cord release add-on that mounts on the hot shoe.

He drew a few of his motivation from a similar job we saw back in March. He took the engineering example from that job which utilizes a little servo motor to actuate the cord release. however along the method added his own features.

The system centers around an ATtiny4313 microcontroller. It supplies comments utilizing the character LCD on the back of the auxiliary flash body. That flash body likewise uses a battery compartment which supplies power for the manage circuitry in addition to the servo motor. ideal now it functions as a count-down timer, as well as likewise can hold the shutter a specified amount of time. however we might see this prolonged to work with outside sensors to activate at a set light level, when sensing motion, or from a remote control.
