Testing bulk LED filaments
Added 2021-11-08 18:02:32 +0000 UTCThis video started as a simple test of a pack of bandoliered LED filaments from Aliexpress, but kinda turned into an experiment with driving them all from a capacitive dropper.

There's a link to the listing I bought these from in the YouTube description. It's a pack of 100, but 105 were actually supplied.
The 1872 LED reference is the 104 filaments with 18 LED chips each.
Mine all arrived intact, but that depends on how nice the postal system is. An order for coloured filaments paced at the same time from a different seller had about half of them pre-snapped. I'm not sure if that was during shipping or if they were pre-broken dumpster-dive LEDs.
Comments
I think I managed the very first video on the filaments when they first appeared.

2021-11-17 00:28:13 +0000 UTCYeah, I'm holding off for a bit on a few things(*) I'd like. (* ie, i've ~100 things in my basket and probably ought to shift stuff onto wishlist or something because it's getting silly)

2021-11-09 22:31:42 +0000 UTCThe first few lots of 100 I found on Ali listed the voltage at 47V. Fair warning to others though, it is approaching the Aliexpress 11.11 "festival". That's where for the month or so before vendors raise their prices just to put them on "sale" on 11.11 at still over usual retail cost. Not a great time to buy.

2021-11-08 23:20:17 +0000 UTCWith a suitable transistor you could probably drive a few.

2021-11-08 22:14:58 +0000 UTCThat's not a bad idea. Maybe with a resistor too as a precaution.

2021-11-08 22:13:51 +0000 UTCFor polarity testing you could just use your insulation tester. It's limited at about 1.6mA.

2021-11-08 20:38:33 +0000 UTCSo funny, again something I recently bought for the sake of trying out.. (last month). This happens often,that I buy some stuff and see it here a little later/earlier.. 🤣🤣
2021-11-08 20:20:06 +0000 UTCLooking forward to the DIY Dubai lamp schematics. Can you also do a 120V version?

2021-11-08 19:35:51 +0000 UTCThe release of LEDs in 1872 is what most economists claim is the root cause of the Panic of 1873.

2021-11-08 18:46:59 +0000 UTCImagine the Pharos Of Clive of Man the equivalent of the Ancient Pharos (Lighthouse of Alexandria in Egypt) It would be lit by a million LED's from Ali Express, and powered from a set of poundland 4000mah Powerbanks!

2021-11-08 18:31:54 +0000 UTCI'm just wondering, how many of them could be driven with a single Joule Thief...

2021-11-08 18:28:46 +0000 UTCThose LED's have come down in price substantially from their £5 each price a couple of years ago. Time to try and buy some for fun things to make.

2021-11-08 18:22:01 +0000 UTCIs there a glassblower on the Isle of Man? You could do a massive lightbulb.
