I have a relatively cheep LCD clock in the kids room (Grow Egg Clock) that is supplied with a ac/dc adaptor, 8V 500mA.

As the little moster keeps playing with it I'd like to put it on a shelf but there's no sockets near by.

Was considering one of those 9V battery enclosures with the correct lead, can pick them up from CPC and use rechargeable.

What are the likly outcomes?

1, "It will kill it you moron, what are you thinking" in which case any better ideas?

2, "it'll work but may damage the clock in the long run" in which case I'll take the chance.

3 "the solution is so obvious you fool why are you bothering us" in which case himour me and let me know.

Thanks
 
OK, just looked it up and the thing is illuminated!

Why can't you just extend the ELV leads round, you could get away with twin bell wire sort of stuff.

Don't, that was my suggestion.

Apparently it would be a strangulation hazard, no more that the little monster playing with the clock was my retort.

She who must be obeyed was not amused.

Even if you put it in some small plastic trunking on the wall?

A set of rechargeable batteries is probably your best bet. Using 6 * AA at around 1.2V/cell is 7.2V and probably close enough, or go for larger like C/D to make it last longer between charges.

I can't see them putting on a 4W supply unless the thing takes at least half of that in power, if so (guess at 200mA, unless you can measure it) the AA size are around 2Ah capacity so you would only get 10 or so hours per charge. So really you would want D size, which bulks it up a bit in size and cost.

RS have a selection of 6 * D-cell holders which hopefully this URL will show you:

CPC don't seem to have 6-cell ones, but you could put a 4 & 2 together in a box, etc, if needed:

Can you get above the room, such as in the loft and power it from up there, and drop the cable down from the ceiling?

Clever :)

I was going to suggest one of the adaptors you got for powering stuff from a bayonet light outlet but then realised I was 5 decades out...
