Hi Lawrence, Great! I suppose I should warn you,though, that the PIC doesn't CONTROL the voltage, it just measures it. It is a traditional dual linear regulated supply with a 16C71 and an LCD added to monitor the voltage. Perhaps it would have been better to go with a switching supply, but I had already started the linear regulator design when peopl suggested it.
