Poundlands 2021 Halloween lights (and USB hack)
The local Poundland has been struggling with some stock this year due to the effects of covid and brexit. I picked an item from their meagre display for us to explore and hack.
This is a string of orange phosphor based LED lights. They are actually a blue/UV LED being used to stimulate a layer of orange phosphor to give a brighter and richer colour than classic orange LEDs. It's a really nice soft orange with a hint of pink.
To make the modification for guilt free running with USB chargers instead of batteries, I added a 10 ohm quarter watt resistor in series with each of the two wires. That results in a current of 100mA and total power dissipation of about half a watt. The current is high enough that it should prevent most "intelligent" USB power banks from going into standby.
You can adjust the intensity/current by using different resistors. Using 5.6 ohm resistors would increase the intensity and using 22 ohm resistors would decrease it.
The components needed are:-
String of chosen parallel LEDs
Two 10 ohm resistors
Salvaged USB cable
2"/50mm of 2.4mm diameter heat shrink
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:-

This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
