I am by no means an electrical person when I decided I wanted to do this project but now that I am started on it I want to finish it.

I recently bought a Binary clock that I was under the impression was a battery powered clock but much to my amazement ... it wasn't. However, I wanted/needed it to be. So here is my way of thinking on how to get it so I can use a battery for it, if there is a easy way please buy all means tell me. =)

Here is what is printed on the plug -
Plug in class 2 transformer
model no:A9-159
Input: 120V 60HHz 5w
Output: 9VAC 150mA

1) Buy a <a href='http://www.radioshack.com/product.asp?catalog%5Fname=CTLG&product%5Fid=273-1770' target='_blank'>AC to DC power adapter</a> and <a href='http://www.radioshack.com/product.asp?cookie%5Ftest=1&catalog%5Fname=CTLG&product%5Fid=273-1745' target='_blank'>9V battery extension</a>

2) Dismantle the AC to DC power adapter and remove the plug in prongs.

3) Replace the prongs with a plug that fits into AC.

I am not sure if I there is an easier way or if I am doing it wrong so if you have anything to say, say it.

    It sounds like you're going to a lot of trouble to do this. Probably, all you need is to do is open up the clock, dismantle the section that attaches to the ac adapter and attact the 9V batter connector to it. Before you do any of this, though, you might want to measure how much current it draws, as it may not be designed to be power effiecient.

    You mean you want to hook up a 9v battery to that clock, right? Then you would need to buy a DC to AC adapter, unless that thing works backwards, which may or may not be the case. Also, It may be a good deal cheaper/less time consuming/less risking screwing up and frying your electronics to just buy a new clock that runs on batteries.

    It is a binary clock (from thinkgeek) that I like a lot. Also a AC to DC adapter would still need wriring.

    You keep saying AC to DC adapter. It needs to be a <u>DC to AC</u> adapter. I'm sure they can be found, but chances are that if you put 9V DC in, the result will be less than 9V AC. It might still work though. If there isn't enough current, you can always hook up multiple 9V batteries in parallel to power it.
