This was exactly the kind of conversation I was looking for.



This means, that I have to decide on the exact ICs capacitor sresistors etc. right form the word go (After the conceptual design is done)

Secondly, I could get a wood casing fabricated (because from where I come it is easier to get a carpenter to do one for me) with an internal layout similar to the final product and do all prototyping on top of that. I hope the casing does not have much effect on the performance.

Finally the question, why would a charger be sensitive to layout? Is it because of the use of a transformer?

And again, are there alternatives to using relays and transformers?

Thanks a lot Erik!
