Poundland USB vacuum teardown.

I'm not very keen on the use of violent inductive loads in laptop or computer USB ports, but this vacuum does yield acceptable results when used with a USB power bank. This video features the mass consumption of humble pie as I jump to reckless conclusions twice.
This vacuum also features a very hot transistor used in a rather odd and minimalist way to bring the thing slightly nearer USB compliance. And I use the word "compliance" very loosely indeed.
