Right, so I’m not sure what the purpose of the cost estimate is. To show you don’t need expensive tools? If that’s the case, then 200USD is massive over-estimate. You only need a soldering iron, and the parts. If you’re looking at the time costs, as I’d estimate this would take maybe a day or two. The time/human resource cost isn’t that right either. But.. I’m just not sure what the point of the article is...
