Cable tester

Well.. This was requested, and first i thought that nah. Not gonna do it. But after thinking about it for a few seconds, it didn't feel like that bad of an idea. So i drew up simplest "original" design i could ever do. The idea is that you attach a cable to two shielded jacks. There are LEDs for both, the core and the shield wire of the cable. If the connection is solid, then the LED will stay lit. If wiggling the cable makes the LED blink or they don't light up at all - well then. You better get a new cable. I made two versions. One with completely unnecessary switches and the other with just simplest wiring i could come up with. This may be useful little utility for some people - and maybe even a nice purpose for those tiny leftover pieces of board :)

Anyway. Use shielded phone jacks and dc jack - stuff them into 1590A - Instant cable tester. This one  won't probably need a verified tag :)
