Imho the Rpi is an excellent example on how not to rely on external power
supplies of the 'standard' kind. 5V charge USB standard for today is 1A, no=

2A, regardless of what a certain company claims.

The duino is another example of a really badly 'designed' product which
caught on. No reverse voltage, high voltage, or overload on regulated outpu=
t
protection whatsoever, and 20 odd MCU pins connected to pins people touch,
with no current limiting whasoever. It is a cash cow because the average
dude fries about 3 in a row before he gets anything working, if at all. At
27EUR each for a 'free' product, which contains a $1 mcu and a usb adapter
which should be externally plugged on, the sales certainly support the
'ecosystem' (their phraseology here, just quoting). Yes, duinos and their
'master' users are one of my pet peeves. I am sure a lot of people make the=
