A long time ago I came across a decorative mobile being sold in a gadget shop. It had a battery operated rotator and a choice of mobiles to suspend from it, mostly UV-active fluorescent plastic.
The most intriguing thing was the rotator, since it claimed to run for months on 2 AA cells. I bought one to take the rotator apart and found that it used a motor directly driving the attachment point and relied on running the motor in short bursts to wind-up the thread between it and the rotating mobile. It was basically using the thread to store the rotation like a spring and release it slowly.
I'm not sure if they make those any more, so here's one you can make out of a cheap air freshener unit, which provides the motor and the circuitry that runs it briefly every several minutes.

Clive, that's an Airwick air freshener. Airwick is made by the huge, anonymous UK company Reckitt Benkiser, now just 'RB'. I used to work there many, many years ago when they were called Reckitt & Colman. I'm guessing the processor is named RB1401C because it is made for RB.
Thanks for your videos – it has made lockdown bearable and I have learned such a lot.
I have now a beginning of understanding decoupling capacitor function. Very many thanks.
At almost 60 years of age now I have never seen one of these & now that I have I'm still not certain just what it really does or is for. WOW!!!!!!!
I love love love your accent. 🙂
These ZVS flyback induction heaters from Ebay seem extremely cheap until you see the circuitry. Then you realise how simple they are and how poor they will perform due to the inability to create a tuned circuit for the average purchaser.
Please overclock it.
I am wondering if those super cheap ultrasonic cleaners powered by a couple of AAA batteries actually do anything or do the batteries just power an LED to make it look like they are.
……. I would be locked in a MATRIX type loop waiting for the ball to eject !
would you be doing more of "electronic basics on components"??
Thanks for this video.

Are you there ? I really need to talk to you about a bargin ? How can i ? Please respond me 🙂
The package of the chip is a SO8, in case you want to know.
These chips are easy to solder. Even the smaller TSSOP packages are not that hard to solder. You just need the right tip 🙂
Sometimes I have to solder some QFNs on a pcb. That's hard tho.
Hey Clive I have a question (not related to this video).
At work we use a Titan electric breaker (for breaking out concrete and what not) and it was plugged into an extension lead (fully un-rolled) and after we unplugged it from the extension lead we saw that there were burn marks on the top and bottom of the Live and Neutral pins. The machine works fine, there were no blown fuses and not breaker trip.
What could be causing that?
(Sorry for the essay)
how come the orange ball didn't explode ! you said my orange things explode because they are orange !
You could insert a small circuit board and LED into the ball to provided randomly flashing illumination too
y tho
