Figure A4. The lightcrafter as optogenetic stimulation light source.

Figure A4

A, remove the projection lens (yellow arrow) by gently wedging it out of its mount with a screwdriver. To bypass the native LED driver, populate Jumper 30 (white arrow). Unplug the connectors (purple arrows) for the blue and green LEDs (cyan arrows). B–D, using spacers (orange arrows, B) mount an aluminium plate with adequately spaced and threaded through holes (C) to mount the external LED driver (D). E, on the LED driver, mount connectors for the blue and green LED and connect them to the LED+ and LED− terminals (white arrows) in a series configuration and solder a pull‐up resistor (blue arrowhead). F, the lightcrafter is mounted on a manual xyz tip stage which is approximately inclined by 10 degrees. Without the projection lens, the lightcrafter projects a primary image (white arrow) approximately 10 mm from the front housing.
