NovaGemCDR™ Coin Drop Replacement Pushbutton LED Replacement?

Thanks again. I think I will get the power from the PSU. But while I am at it, I have bought some Logitech Z110 USB powered speakers (although the sound signal is through a normal jack), do you know if these babies can be powered using a normal HTC mobile charger? I know my HTC charger outputs 1 amp and that it can also be used as a Raspberry Pi PSU. You say that each powered USB port can maximum output 500 mAh so I guess these chargers would work brilliantly then? Just wondering in case I will want to use the speakers for some other stuff where I dont have a USB port available. (I also think the Z110 ones are too big for my project as well actually).

Good news, the Z110 USB powered speakers work fine on a HTC mobile charger. It would probably run fine from Samsung Galaxy charger as well as Asus Transformer charger, both also have a standard USB port on the power brick. Also the sound in the Z110 is really good for such small cheap speakers.
