Hello, Giampaolo, and thank you for showing up.
I love the design of the Penta, so I'm going forward and starting to build one. However, I've just realised that some of the most interesting words in Portuguese have 6 letters, so who knows an "Hexa" device might come to be sometime? Of course, I have no idea if it's possible to stick an extra digit/character there.
Anyway, I've got a few questions about the Penta.
- What modifications are needed for it to work under a 60Hz mains?
- What's that capacitor on pin 3 of the MC34063? It's not clear in your drawing, seems to be '1M'.
- There are 3 different drawings for capacitors, does that differ the electrolytic from ceramic, and so on?
- What's the dissipation on the resistors? don't know if there's any difference between the two different drawings of resistors also.
- What are the specifications (or just the type) of the four diodes making up a bridge at the main power source?
Thank you
(Everyone, please feel free to answer)
