A great nightlight comes from a DVD. Not annoying, sufficient for soft lighting. The light image on the disc changes depending on the location of the viewer, and the impression is "stereo". It is done quickly and easily. The pictures were taken by phone, please do not scold for quality.
The original is very clear and colorful.
NECESSARY:
1. The disk is dark coated, can be double-sided.
2. The bottom of the box for DVDs.
3. Foil textolite for a round LED board, you can use a finished board from a broken lamp.
4. LEDs on 3v-9v and the POWER unit on 5v-9v from the phone. Holographic film self-adhesive.
5. LEDs at 3v, resistor at 200 ohms. for current blanking. Copper wire from a 05mm transformer for connecting the central LED and the leads to the rear wall of the box.
6. Hot melt adhesive.
7. Cap from kindersurprise or bottom from any layer of bubble. That's all.
WE COLLECT:
we cut out the board (40 mm diam.), use the compass to mark the current-carrying paths and the position of the LEDs, drill holes for the diodes and wire leads and solder in accordance with the polarity (see figure). We turn the external diode (you can make the “tablet” brighter with dispersion) and fix it with glue in the center of the board, put its conclusions through the holes and solder it. At the two ends of the PEL 05mm wire, 100 mm long, we clean the ends from the insulating varnish, solder and mark the polarity of one of the wires with a drop of hot glue. Gently twist and push through the cropped nose of the box. On the reverse side of the box we glue the pieces of foil-coated textolite to them, solder the output from the lamp, the 200 ohm resistor and the ends from the power supply. We turn on and check the performance. If all the right diodes light up. Next, I glue the board to the nose of the box (the distance from the disk to the LEDs is 15 mm).
In general, you can adjust the focal length of your choice, depending on the change in holography, I was satisfied with 15 mm. We cut out the decorative scarf, glue it to the circuit board and that's it. The design of the lamp can be done to your taste and color.
