Several people on here have asked me about some of the things that I have played around with, concerning making motorcycles etc.
I just came across this video which was made in 2012. The first 14 mins are in Spanish and the link starts from that point.
The sound is not great because I did it without a mic. but it is mostly understandable. I usually use my own wireless lapel mic. but I was assured that they had everything, but as it turned out they only had a wireless lollipop and as you'll see I use both hands when explaining stuff. I don't do hand held mics.
