RE: Stepping up 120v - 240v - can the Hz be converted too?

["White, Peter" <peter.white@xxxxxxxxxxx>]

Thanks. I took it apart this morning (one of the 'wooden LED"
clocks
marketed by the Science Museum amongst others), but no pin, so I guess
I'll try to find the equivalent over here, and re-gift it for someone
back in the UK!

Replace the clock will be the cheapest thing you can do.

Some of the clock ICs used in cheap clock radio type clocks have a
50-60Hz
pin on them, I modded a novelty clock for a friend that came from the
states
to be happy on 50Hz - worked fine till his GF plugged it straight into
230..

Happy new year all.

I need to convert 110v - 240v, for which there's a bunch of wall-warts
on eBay that'll do the trick(eg: http://tinyurl.com/8z2sox ).

The problem I might have is that it's for a digital clock, which having
plugged it into 110v actually works, except it runs fast, which I assume
is because I'm on 60Hz over here (US), and it's designed for 50Hz. So,
does anyone know if these converters also convert the Hz, or, if not,
whether there's something cheap I can do?

Thanks, Pete
