  2. Hi Dave

    Nice work as usual – but a quick question:

    Can you predict the limits of output current using the reactance of the caps (i.e. Xc=1/jwC)- so you can design a supply in rather than measure it?

    Thanks,

    Simon

  3. Have you ever considered about adding a little bit more than just your articles?I mean, what you say is important and all.However imagine if you added some great graphics or video clips to give your posts more, “pop”!Your content is excellent but with images and videos, this site could definitely be one of the greatest in its niche.Superb blog!
