Overlay-lighter on a laptop or tablet



You decided to make a video call. Communication works fine, sound and image are transmitted with high quality and stable. But the interlocutor sees you like this:



Something needs to be done with this. Now it’s better:



Want to know how the author of Instructables under the nickname Toolify achieved this? Read on.

The wizard measures the dimensions of a tablet or laptop cover. Entirely, not just the screen. After all device should not cover the front camera.




Makes frame parts from plywood with this requirement in mind:





Sanding with sandpaper:



Selects one of the following connection methods:



Saws according to the selected method, then glues, exposing right angles with squares:




Glues the LED strip, solders the jumpers so that its pieces are connected in parallel in the same polarity.






Done:



If connected to the PSU, it even works:



But without an aluminum heat sink, the tape will overheat and will quickly fail. It is possible to use a PSU with a reduced voltage of about 10 V. But the master makes a step dimmer from eight diodes connected in series. On each of them drops about 0.7 V. You can switch the taps, choosing the voltage supplied to the tape.






Of course, it is better to place such a dimmer in the case, connect the parts by soldering and supplement with a wrench switch. And you can start video calls. You will be seen better than when illuminated by a frontal spot flash, which, moreover, is not available on all devices.

Topic not disclosed xxxxx fixing the frame on the screen. Not everyone likes LEDs that shine brightly in their faces; they should be closed with some kind of diffuser. And instead of a pseudo-dimmer, use an adjustable voltage source.
