S-video Converter
Published in issue 391, July/August 2009
The converter we are suggesting building, very simple since it only uses two transistor, lets you convert any S-video signal into a composite signal and so will perhaps enable you to give a new lease of life to your old CRT television.
Resistors R1,R2,R11 = 75Ohm R3,R7,R8 = 470Ohm R4 = 560Ohm R5 = 27kOhm R6 = 10kOhm R9,R10 = 150Ohm Capacitors C1, C3 = 100nF C2, C4, C8 = 470µF 25V C5 = 10nF C6 = 10µF 25V C7 = 220nF Semiconductors D1 = 1N4004 T1 = 2N2222A T2 = 2N2907A IC1 = 7805 Miscellaneous 4-pin mini DIN connector Cinch connector (yellow) DC supply connector
