Some coffee maker hacking…At work we got new coffee machines. The supplier is the Dutch company Douwe Etters. It immediately became apparent that the coffee was not up to spec compared with our former supplier. Complaints did not result in better coffee, so I decided to try to do something about the weak coffee with froth (foam) on top of it. After all, everybody knows that foam should be on top of beer, not on coffee! On the plus side, the coffee is free… Link.
