I guess they tried to make this little light as universal as possible. It can operate with any polarity and with a huge voltage range of 5V to 58V, which it then efficiently converts to drive a single red LED at 50mA.

This is quite a functional little module. The resistor is properly rated for power dissipation and the separation is good.

It appears YouTube have restricted advertising on this Saturday's stream before it's even happened. I guess that must mean it's going to be a rude one.

Dave Jones at EEVblog dives and finds fancy computers. I dive and find an old Honeywell diverter valve.
Actually quite well made and very serviceable.

Since every other video I was working on has gone "complicated" or required further materials, here's a nice plain light teardown and assessment for hackability.

Regulars to the channel may get Deja Vu, as I've covered these suspicious devices in the past.
The reason I'm covering them again is because there's been a burst of particularly scummy advertising that is using stolen pictures and videos and literally creating a fake story about how the you...

This isn't what I thought it was:-
And the circuitry wasn't what I thought it was going to be either.
It was almost harder to reverse engineer because of its simplicity.
An extra lock-downy stream as we've just locked down again.
As always, the live chat can only be interacted with if you view the stream on YouTube.

Kinda short notice at about 21 hours before the event, but I'll be doing a quiet Patreon stream.
Let me know if you have any subjects or questions you want answered in the stream.

This classic Chinese night light has one very appealing feature that makes it non compliant with most other countries. You can change the LEDs at the risk of exposing small areas of live metal while doing so.

I've looked at these things before, but the circuitry always seems to be different between units.
