Dangerous DIY Krampus LED foliage lamp.

Note that this bizarre "lamp" is totally non compliant with most countries electrical safety regulations. The mains voltage version is more of a naughty novelty for those of us with no kids/pets, a liking of the simplicity of the circuitry and the extra zest of its dangerousness.
The video also includes a quick guide to making a much safer USB powered version at the end.

Regular viewers of the channel may get a slight sense of déjà vu as I've made similar lamps in the past in different styles. I've called this one the Krampus lamp as it has a strong Christmas colour theme, but is much less charitable than Santa. It is capable of imparting electric gifts to meddling fingers in the form of electric shocks capable of tossing your body into the air like a ragdoll. That's what makes it special.

To comply with snowflake regulations I have to advise against trying to build the high voltage version of this light. The safe low voltage version is fine though.

It was good to find a source of the little "Molex" terminals on eBay, but less good to find that the contacts are slightly narrower than the ones I normally use. This probably isn't such an issue if they are used in a normal way, but with the use of solid core wire with the rotational tension of the twisting of the wires it may have made the terminals sit at an angle inside. I had an issue with a few LEDs not making good contact initially and that's hard to trace in a long series circuit of about 43 LEDs. Not such a big issue with the USB version as each socket is independent, so finding a rogue connection is easy.

Here's a search link to find the connectors:-

The plastic foliage really makes a huge difference to these lights. The stuff I used came from a UK pound shop (The one opposite McDonalds on Sauchiehall St in Glasgow, Scotland.)
You can also buy stuff like this from eBay as artificial foliage:-

It turned out really well. The circuitry is simple enough and "low stress" that it should last for a long time. The fact that all the LEDs are ion sockets also allows updating with fresh LEDs at any time with different colours, just fresh new LEDs (they fade over time) or colour changing LEDs. Note that LEDs that flash as part of their sequence will need to be used with the USB powered version.

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