Module Wi-Fi Luminograph

The module sits between the wall socket and the Luminograph, with no change to the machine itself: the unit keeps its own switch, and the module simply gives or withholds power. Exposure time is set in the Calibration Flow app, on iPhone or iPad, and the countdown is then handed over to the module. That handover is the point of the product: once an exposure has started, the device that ordered it can lock, close the app or leave the network, and the cutoff still lands, at the second it was set for. Nothing further depends on a connection staying up.

It replaces the kitchen timer and the need to stand and watch: long processes — gum bichromate, carbon transfer, pigment prints built in successive layers — run to tens of minutes, repeated identically from one layer to the next, and it is that exact repetition that makes a print consistent. It replaces no setting on the machine: the module opens and closes the power supply, and controls neither intensity, nor spectrum, nor channel. Compatible with both the Luminograph A4 and A3+, it fits an existing setup and is removed just as easily.
