Summary: use optocouplers Message-ID: <1305@leah.Albany.Edu> Date: 1 Dec 88 07:20:27 GMT References: <3ff08ff4.d753@apollo.COM> Distribution: na Organization: The University at Albany, Computer Services Center Lines: 11 I built this modification into a TV about five years ago. I think there was a project in SCIENCE & ELECTRIONIC magazine 5 or 6 years ago. It used optocouplers and coiled wire around the xformer to draw off 12v to power the board. It sounds real simple, but there's more to it than there seems, sorry I don't remember much, but this was done years ago in High School. Good Luck, Ken Zinssar Poor College Student :
