First of all, this is not the place to come with those silly ideas that ATMEL and Microchip use to sell their products to the fools who will buy them. Both companies started out selling to uninformed hobbyists, especially Microchip. ...but, unfortunately, what they show in their cheap application notes is very common design practise! Mains capacitor power supply, connecting signal ground to mains and using non-surge prooved components is right what you get, when you have a shopping tour in a DIY market or lamp shop. The point is, that in the hand of a newbie who just wants to tinker a bit with this stuff, this can easily turn out to be deadly. The authors of these application notes lack all their responsibilities. What they do is just criminal! Kai Klaas |
