Description: In some areas of forestry and wood utilization research, use of automatic data recording equipment has become commonplace. This research note describes the basic electronic components needed to modify an existing intervalometer into a simplified pulsing device for controlling an automatic data recording camera. The pulsing device is easily assembled and inexpensive, when compared to similar proprietary units.
