Really? It's easy to sit back behind a keyboard and make comments about someone's knowledge or lack of, it's another thing to put yourself out there and open yourself up to scrutiny from other knowledgeable people. I mean seriously, you have it broke down to 25%, How about some details? I personally can put some clout in that, Much more than just attacking other members with innuendo's about there personal life.
AvE is knowledgeable about a great many thing. But his knowledge is broad but at times shallow. For instance, I recall several instances of him talking about lithium battery charging and capacity. Now, I've designed commercial products with lithium batteries and am decently well acquainted with lithium chemistry and charge management, and I can tell you he has a superficial knowledge of the subject but he simply gets many of the details wrong. No sin in that, but if you're going to shoot down a product because you say the manufacturer's claims are wrong in terms of battery life, it would behoove you to get the details right.
My sense is that AvE probably has a background as a manufacturing engineer. A good manufacturing engineer is worth his weight in gold, but it a different discipline from the design engineer actually having to make real trade offs in product development. My impression is, he has no experience in that area. I could be wrong but that's what I get from watching his videos.
Trust me, you guys don't really want a product designed by the AvEs of the world. If at every design decision point you put in the most premium component you will end up with a product that costs too much, weighs too much, and will in fact flop in the market. A drill that last 50% longer, but costs 75% more and is 30% heavier is not a product that is going to sell. Those are just the facts. I promise you, the guys that have been designing cordless drill for years know far more than AvE about where their products tend to break, where they need to use premium components, and where they can get by with less, and most importantly what their customers are willing to pay and what is the best trade off in terms of product life versus cost.
In fact, it is AvE that is armchair quarterbacking when he says "oh, this sintered metal gear is ****, they should have used a machined part here". He's not the guy that will have to answer to his management when his overly expensive, overly heavy product does not sell. He's just the anonymous guy in Canada that pronounces that it isn't "skookum".
