Arch, do you use any king of voltage regulator on your boards which you make yourself? If so, so you have a low power 5 volt regulator that you can recommend. All of the ones I have are 7805 derivitives and tend to have a high quescient current draw, around 5-10ma usually. Any suggestions? At full power, my controller board will draw no more that 100ma (with both relays activated). At normal standby, around 10ma.
