You could make Twister1 if it's a viable option. The only problem you get is increased
EM interference. If you place Ronja next to a TV antenna people could complain. I did
Twister2 because someone complained about this situation. In most other situations
noone complained however. And Twister1 also takes more power because it has an inefficient regulator.
