evening BIG Clive and family from Salford

2020-12-10 21:55:46 +0000 UTCI would greatly prefer a zero failure rate, as a rogue pixel can kill an entire line at that point.

2020-11-29 02:53:39 +0000 UTCA possible question for later, although the answer probably isn't an absolute. When buying WS2812 Pixel Tape from China on eBay, what is an acceptable LED failure rate?

2020-11-27 23:23:07 +0000 UTCThanks for the tip. After having no luck finding colour fading LEDs without a ferocious green, I tried applying a magenta sharpie to an LED to absorb some of the green light. With diffused LEDs, it made a surprising difference and can finally get yellow and white in the colour fading cycle.

2020-11-27 22:53:12 +0000 UTCThe caps of those lights can often be liberated from the LEDs by dripping a drop of isopropyl alcohol into them the dissolve the glue. Then you can reuse them on your choice of LED strings.

2020-11-27 21:40:54 +0000 UTCI finally found a few keywords for bulb style fairy lights - strawberry and pinecone. They even come in 5 or 6 LED colours, just like the traditional incandescent sets. I bought a 6 colour pinecone set on Amazon, so looking forward to them. I'll likely mod the set, i.e. convert to a static two wire string and double the spacing between the bulbs.

2020-11-27 21:29:34 +0000 UTCThe panels aren't too bad for flicker as they have a large linear surface. In the right circumstances a camera can show a strong visual ripple with traditional tungsten lights.

2020-11-27 18:43:53 +0000 UTCWith some lamps you can put a capacitor in series and it tames their output intensity, but for smoothing, only some lamps will work well with external DC applied to them.

2020-11-27 18:42:34 +0000 UTCCould you kludge a big red film cap for those lines❓ after the rectifier of course... thanks to BC i replaced and tuned a misbehaving room fan cap... you know those big black boxes. It came with a 6 uF, replaced with a 4 uF and it now puts out a smoother stream of air (noticably quieter)

2020-11-27 16:55:51 +0000 UTCYeah, I sometimes wonder whether the fact basically everything indoor is probably flickering at 100Hz could be a problem. The flourescent tubes at work got replaced by LED panels, I didn't notice they flickered until I used my webcam that defaulted to 60Hz. I'm not that worried actually...

2020-11-27 15:36:36 +0000 UTCThe conspiracy theorists claim that LED lamps cause eye damage. They casually ignore the fact that walking outside exposes you to massively higher levels of all light than a standard lamp could produce. My only problem with LED filament lamps is with the ones without a proper smoothing capacitor, that flicker.
Big Clive
2020-11-27 12:18:36 +0000 UTCHeard someone say those bulbs are bad for ones eyes? More misinformation I guess.
Andrew Donaldson
2020-11-27 12:04:18 +0000 UTCWell I will be there with trashy bells on!
