Making a video about something like this is almost like a holiday for me.  Very simple circuitry that is fast to reverse engineer.

This is the fourth video I've made about this style of light over many years of evolution, and they have all been different.

They're very hackable, and could be used to make low level wire-free garden festoon lighting with your choice of LED colours, or you could use the case as a base for a completely different project.

Different again! This one came from One Below, or possibly now One Beyond. I think this one has the harshest LED current yet, but has easy hackability, including changing the current limiting resistor and the LEDs to ones that fit your needs better. It could also be converted to use a rechargeable lithium cell, although it will accept three rechargeable AAA NiMH cells as standard. I regard these lights as a useful base for customisation, or even as an enclosure for other circuitry. Mid-play video-adverts are annoying in technical videos, so I don't enable them. If you appreciate that and enjoy my content then you can help support the channel with a contribution of a dollar or two a month on Patreon. That also lets you critique the (advert free) videos before they are released, gives a more direct means of communication with me and also gives access to the regular relaxed Patreon live streams. https://www.patreon.com/bigclive #ElectronicsCreators

It is always interesting to see you document the evolution of these cheapie gadgets. By the way - I know I told Clive I wasn't going to sell the bigger version of the "square supercomputer", but I changed my mind because the shipping charges were misquoted to me originally. So if anyone wants a 150mm square supercomputer with 324 LEDs on it... it's in my Etsy shop :)

All postal services seem to be notorious for upselling shipping costs. If you look at their price guides you can often optimise the size and weight of items to fit into slim and economic packaging and rates.

red light is good for beekeeping. It doesn't accidently make the bees think it's morning when working around the hives at night. Astrologers don't need red light. They don't actually look up in the sky. Their zodiac is off by a month because they haven't updated it in thousands of years.
