This scene is about 24 mins in, after Gaff and Deckard entered Leon’s apartment for clues. From the sweep of the lights (clockwise as seen from the front), the revolving beacon is placed slightly forward of the middle. Shame I cannot put 10 LEDs in there without using more wires as designing the 8mm PCB is quite a challenge.
Here it is again, towards the conclusion of the fight with Roy. The LED I am using would have to have some kind of lens.
Assuming this is the interior height for that part, I have about 0.9mm left. The two PCBs would take up 1.6mm (0.8mm + 0.8mm), the 0805 SMD LED would have the ‘height’ of 2.2mm. So, its 4.5-0.8-0.8-2.2 = 0.7mm. Which is just enough for a paper-thin double-sided tape or some hot-melt glue. And just to be sure, the soldering would not be at the base of the PCB which can be quite a challenge.
This board is about 8mm across and fitting 10 LEDs in there is quite difficult. The design above is for 0805 LEDs without the connections. Another solution would be to use addressable LEDs. This would create two other problems, namely developing another microcontroller for it (making the count to 4 microcontrollers), plus soldering these these LEDs vertically is going to be a challenge since it needs to be connected on both sides.
This is a typical WS2812 RGB LED. Connection-wise, they are a dream because all you ever need are just a minimum of three wires.
This is a typical 2xx x 2xx WS2812 LED. It’s quite small and now I have to figure out how to control them. I mean, how does each LED know it is being addressed to?
