It's really easy and quite enjoyable to add LED features to Xmas and birthday cards, and they will literally run for weeks on a single set of batteries. Note that I've nothing against the red cross and it's valuable volunteer workers. Just the issue that a significant percentage of their income goes to the management who then use those volunteer workers to do the actual work.
The LED tester is a very common unit on eBay. They're quite handy to have. Here's a general purpose eBay search link:-

All the LEDs used in this project should be matched if using them in parallel with a single resistor. For other colours you could use individual resistors, although the LED with the lowest forward voltage will tend to slowly drag the battery pack voltage down below the point where the others can light.
When testing the LEDs for balance the one that is brightest of the parallel clump is the one with the lowest voltage, so it steals more of the current.

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

I absolute loved this video, please do more of this type of relaxed layed back stuff!
I‘ve used some incandescent teeny bulbs (or rice bulbs) long times ago to make Christmas cards for my classmates at the time, they looks nice and bright. (To save energy, I provided a tin-foil button there, so it will only light up as they press the button down.)
I think it's called the nap of the fur. But anyway, we used to have a bunny rabbit who actually did chew any wire he could sink his little teeth into.
We had to confine him to the bathroom before he became an ex-rabbit.
Fortunately, my sister, who has a farm with rabbits came over and said "What are you doing to that poor rabbit?" Needless to say, we quickly said "Ok ok. Here, you take Snowy."
By all accounts, Snowy is now living peacefully with other rabbits, and is obviously not a "he" because there are many little offspring bunnys hopping around 🙂
Nom nom nom is my favourite 👍😘
Before you even said this is just like Blue Peter, I'm thinking … Oh it's just like Blue Peter for Greenies ! ( Greenies is the navy term for electricians) !
Aye, as made by a true Scot, spending as little as he can get away with, and depriving some old granny of the right to feel all warm and fuzzy inside – having unwittingly sponsored someone's boardroom booze up.

With the way the wiring on the inside looks, I'd be tempted to draw a bit more "rail" and a derpy lookin' train at the end. If there's any cheap battery cases that look like boxcars or coal cars, or summat, that'd be perfect! (if you're imagining a masterpiece, it fuckin' wouldn't be, but I do love a bit of shitty whimsy, and I think my family knows to expect disappointment, by now.) 🙂

Very cool. I think could be a great candidate for doing a no or almost no solder version by wire wrapping, preferably with the right sort of wire and tool 🙂

I also feel hot when I concentrate so that is why I work with air conditioning, even in the winter.
Here in the USA, if you have blue peter, you will probably need penicillin shots…Lol

I recently watched the cartoon that snowman came from. It was surprisingly good.
