Hi all, The power supply that I ordered from ebay is a 15Volt 2Amp switcher as follows: 15V 2A 30W Single Output Switching Power Supply Voltage...<http://www.ebay.com.au/itm/280764693188?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649>(280764693188) cost AU$13.00 inc postage. Its small and easy to use. For the 5Volt either a 7805 or a dc-dc switcher that are available on ebay for very little.
