AliExpress unbag joy - High voltage, fire sprinkler, thermal switches, solar stuff

Another bulging sack of technical goodies from AliExpress for us to explore.

These videos are not sponsored by AliExpress. I buy all these items myself.

Here are some links to the items. Some of these are affiliate links, but that will not affect the price you pay.
Keep in mind that these products may not meet your country's standards.
Some listings may not work for some countries and some may just be sold out or disappear.

When paying on AliExpress, let the transaction complete before leaving the purchase page as otherwise it may not go through.

The very nifty high voltage tester:-

Shop around for the best price. It may appear as a bundle deal item.
If you buy one of these - open it and check that the potentiometer mounting pins aren't poking into the lithium cell! They may need trimmed.

The fire sprinkler head:-
