Making the main board

A project log for A Spring-Loaded Digital Movie Camera

Digitize a vintage 8mm camera. Not for the sake of convenience, but for the enjoyment of video recording.

Now that we are able to detect the shutter movement, which had been a pending project, we have started fabrication of the main board.

It has a DC-DC converter, a photo sensor for shutter detection, DIP switches for inputting shooting conditions, and pins for connecting to the Raspberry Pi.
When we checked the operation, we found that the Raspberry Pi was reset due to lack of power when continuous shooting was performed. As a countermeasure, we changed the DC-DC converter from the LM1117 3V3 version board (top photo) to the MP1584 version board (bottom photo).
