Burned out PIR switch

A rather catastrophic failure that sums up so many of the design weaknesses of rogue imported electronics.

It shows that a lot of electronic designs are copied without any real understanding of real life hazards.

'An adorable little hole where a shot of flame cam out' - whoofles!

I toyed with that, but my bench is not rated for high swing-press forces.

It might be corrosion in the vicinity of the switching transistor.

The real problem with having such inferior products in the market is they create a demand for cheap goods, which creates pressure on otherwise safe product manufacturers to cut corners. On top of that is the fact that its impossible to tell whether something is safe or unsafe without doing an expert teardown. (Price is a good indicator but insufficient, because nothing stops a disreputable vendor from marking up the unsafe cheap products to the same level as the safe expensive ones.) We are going to have a number tragedies reminiscent of 19th and early 20th century West before this phenomen get fixed. Which is why BigClive's channel is a service to humanity, if you think about it!

I was also hoping for the X-Ray.

Thankfully smellevision has not been invented yet.

Probably a good thing that it was an outdoor feature.

When you said "I know what tool to use..." I thought you were going for the AvE-Hammer.

Mum has a battery operated solar light with two LED bulbs; they have developed a 24-hour 'glow' feature but still turn on bright when passed. Would you like it for 'autopsy'? If not, what could be the problem? Not thinking to repair it as it was practically free - found it in the skip when Homebase had a clear out a few years ago!

I'm very happy I don't have smellovision. My imagination was enough to make me gag.
