S-video Converter
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.

Gerber file
CAM/CAD data for the PCB referred to in this article is available as a Gerber file. Elektor GREEN and GOLD members can exclusively download these files for free as part of their membership. Gerber files allow a PCB to be produced on an appropriate device available locally, or through an online PCB manufacturing service.
Elektor recommends the Elektor PCB Service service from its business partner Eurocircuits or AISLER as the best services for its own prototypes and volume production.
