What got me interested in electronics was the prospect of making my own cables, at custom lengths.
That was a cool article, but one thing I've noticed with some connectors is that sometimes pin #1 isn't always shield. I recently modded a set of headphones for my kid using a japanese (forgot the brand) female 3.5mm jack and the #1 pin was actually tip (what is commonly #3). It's always best to make sure by using a multimeter and checking for continuity when not sure (noticed a multimeter wasn't listed in the above article, and I think that's essential for making sure your connections were done properly, even when doing basic electronics, like making cables).
I don't like MP3s (or fat-free milk). Actually, I don't even like Dairy. Dairy messes with audio (sinuses). Hemp, Almond & Rice milk don't, so I guess that means I like FLAC instead of MP3s.
