Ultra-thin side emitting LED tape
Added 2025-02-27 17:48:08 +0000 UTCNot just side emitting LED tape, but fully RGB addressable along its length too.
The controller is quite impressive in its functionality as well and can drive up to 154 standard WS2812B style LEDs.

I have a confession. I bought a cheap chinese deskmat that has a light pipe around the outer edge. I love(d) it. I know it is tacky and I'm not a computer RGB enthusiast. But the subtle ambient light it puts out around my desk was pleasant. The light pipe started to develop cracks and the light distribution was greatly effected and I also dripped hot solder on it by accident. I can't find a suitable replacement due to size or colour/pattern. There are many non-lit deskpads around that I might consider putting leds under. This is perfect except it can't bend to the radius I need.

2025-03-01 03:12:46 +0000 UTCI noticed that many of the Christmas style addressable strings seem to scale the intensity to keep the current down. I must admit that I find it a bit squirmy when I see some of the huge arrays used by holiday lighting enthusiasts in America, with piles of open chassis, high current switchmode power supplies in tupperware boxes and no obvious protection against short circuits.

2025-02-28 21:46:07 +0000 UTCI rounded it up to 2mm. It's actually a bit less.

2025-02-28 21:28:12 +0000 UTCAh, but it is not merely a car. It is a fanny magnet. Exactly the type of car that is involved in lots of single vehicle collisions due to operator bravado.

2025-02-28 21:27:41 +0000 UTCI've not really tested the RGBW or ones with amber. I'm not sure how standardised they are.

2025-02-28 21:26:02 +0000 UTCOn the topic of LED tap, is there a RGB/UV(A&W a plus as well) that you'd recommend? I'm not having much luck even finding anything besides seperate UV and RGB tapes. Looking for something to put in the Aubrey II set piece that eats people, in Little Shop of Horrors. I'd planned for an open topped plant pot I could put a couple RGBAW+UV PARs(which I had ordered for the purpose) into, but when the setpiece was constructed, it has a solid top(High School production where every department does their own thing, so no drawings) to help the eaten actor climb inside Aubrey II.

2025-02-28 21:05:25 +0000 UTCIt's already a thing in newer cars. I had a rental Renault two years ago that had decorative light strips and lights in the inside door handles that were customizable. It was also an automatic with several different driving profiles which also afffected the light strip colors and speedometer display. It didn't have chase lights or color cycling though, just static. Still bright enough at night to be potentially distracting.

2025-02-28 19:43:22 +0000 UTCThey recommend a feed every 5m. Fortunately for night-time use I found myself running at very low levels.

2025-02-28 19:34:23 +0000 UTCJust what we need. Another eye-catching distraction for the driver inside the car.

2025-02-28 12:48:54 +0000 UTCThanks Big Clive. That IS very impressive. 2mm even. Tiny tiny tiny!

2025-02-27 22:53:23 +0000 UTC5V is not a handy voltage for these large strings. Too much drop and too much current. You might want to inject 5V on the end of the sting and/or somewhere in the middle as well.

2025-02-27 20:11:18 +0000 UTCI recently bought a 300 LED WS2812B string and PSU to drive it. The connecting wires are skinny and the flexible trace none too convincing: with a stressy program, the voltage at the end of the string might drop to 3.5V from 5V at the feed. However, it holds up well visually. There's no issue with logic thresholds because the chips are close together, experiencing substantially similar Vdd. AC noise is not an issue because all communication takes place while the LEDs are static for a short period of time. The problem is colour drift: the output of the red green and blue LEDs is designed for 5V. If the chip gets 3.5V instead, the blue and green LEDs may be attenuated. I don't think they have constant current sinks.
