Night light with ldr

thingiverse

This is simple night light. I created a lithopane from https://tool.itslitho.com/ using cartoon drawing of red panda ( my son loves red pandas ). Used default setting except set frame option to none. This will give you 0.8mm thick panel. You have to glue the panel and the shade. Be carefull for corners. I used simple perfboard to solder all circuit parts. I already have 5 mm radius ldr. I used drill to open hole for ldr. Please glue small circle part from inner to avoid ldr drop inside the shade. Bulb used https://www.aliexpress.com/item/32642236592.html?spm=a2g0s.9042311.0.0.27424c4duATn4f Circuit that i used https://electricdiylab.com/ldr-darkness-sensor-circuit/ but i changed R1 for intensity and R2 for light sensitivity to best suit my environment. Used 12v power source since my led bulb was 12 volts Also you will need 12v 1Amps power adaptor.
