Title: Hacking USB powered speakers to be Non-USB powered
Post by: electricd on March 13, 2006, 09:34:16 am

Hello,

I just bought a set of the cheapie Benwin USB powered speakers to use for their amp.  Now, I am short on USB ports, so what I would like to do is hack the power to accept a normal wall-wart style power.  What is the  voltage that USB supplies?  I *should* be able to just find a DC adapter that supplies ~ the same voltage and tap it in, correct?  Thanks in advance!

Ahh..so it should be very easy...plenty of 5V DC power supplies lying around...any reason I shouldn't do this?

Would a self powered USB hub not be easier?  Give you more ports as well as running the speakers?

you can get them quite cheap on ebay or a local computer store

Now, I am short on USB ports

What motherboard do you have?  There's probably USB port headers on the motherboard that would allow you to add up to 4 more ports by using a USB bracket or two...

If you'd rather have ports on the front, I recommend this.
I have a few (brand new) that I'd be willing to sell for $16 each (shipping included).
PM me if you're interested.
