I thought it was ironic the he started the video with "never a dull moment around here".

I have always found Mr Carlson's Lab to be some of the dullest electronics content on YT.

First I thought, they came up with some special solder that would work.
I was shocked when Paul took the other solder joint apart and it just fell apart. What a load of crap :palm:

Some books back in my university times stated that in order to weld or crimp aluminium thoughougly you need to first strip the oxide layer with hydrochloric acid, then not waste time, crimp it, heat it and then use nitric acid to oxidize the aluminium again. After flushing and drying a protective soft lacquer is applied.

I have done this donkeys years ago on my first job as a student and we never had a complaint.

well he is not a influencer but a teacher. Very detailed and with the stuff you learn about proper repairs and designs from that channel, I can live with someone not trying to 'go viral'.


And I thought it was exciting to see him go into it after he said it was clipped and glued together, I would just make a 2 minute video that ends with it crashing in a dumpster. Amazing tenacity of the human spirit.

I think we will have a great leap in progress when humans bring the first big ass copper asteroid to be mined on the moon so this aluminum stuff can go obsolete lol. Every time I see aluminum conductors that are not on the power line I think... damn... we need to find more copper out there. Some time after the real space age we will have the 'reasonably good conductor everywhere' age, or hopefully the silver age. 0.15 cents/pound silver.  :-+

Hopefully one day we will look at old technology and see the aluminum conductor like finding a knife made out of obsidian.
