I'm going to look myself, but do you have any links about the 18650 packs? Edit:cheapest aliexpress ones i see are about usd$2.00 each. That's not bad though.

Check ebay, packs from hover boards that got recalled are available. The cost can be $1 a cell, a pack might have 20. Each cell might be 10-12 watt hours. It takes 3 cells to produce 12 volts.

Indeed. I hadn't actually reviewed ebay for electronics things for a couple of years, because any of the products I used to see there were significantly more expensive than anything I could get from aliexpress. It looks like, at least in this instance, that has turned around. I could even see individual 18650 cells for $1.

Great stuff.

Yup, just look at https://en.wikipedia.org/wiki/China_Railways_CRH380A Although I see it as a positive. The money spent to "buy" technology is essentially wasted money.

> Although I see it as a positive. The money spent to "buy" technology is essentially wasted money. Is money spent to buy software also "wasted money"? How are you going to pay the engineers developing this technology?

Just because I make a living writing software does not mean I have to support all of this wealth transfer.

I can live on a decent wage. I don't need to make millions of dollars a year.

Screw "creatives" and screw this madness of royalties and license fees. Of what you're doing is of value to someone, they will pay you upfront.
