    design of short circuit indicator using neon for domestic distribution board

    I think @Bluejets was asking for more specific information like: 1. What do you mean by permanent? 2. Built into the consumer unit? 3. A device for plugging into domestic outlets? 4. Testing for short circuit of what? 5. Live and neutral reversed? 6. Live and earth fault? etc etc etc Be more...

    What is this unit ?

    @Joey4208 If you're still interested in finding out.....Take more pictures of back, sides and the joypad. Make sure all writing, logos and any labels on the backs are clear and readable. Also any input/output connections be clear and hopefully identifiable. Your picture doesn't tell us much...

    Help with a circuit.

    That rotary switch looks like a single pole. 'A' is it's only pole. This should be the common positive terminal. Then 1,2,3,4...etc are switched by turning the knob. Then you can control what you want to turn on. The negative should not be on the rotary switch. Have a separate connector inside...

    Repairing an old radiation detector.

    I would urge you to get a second 'expert' opinion....:cool: Well they are clearly NOT working fine....Did you read post #10? Electrolytic caps do dry out and or leak. Some go dead short. Some restorers wont turn on old equipment until they have first re-capped it. It can save other component...

    How would a twisted pair effect a signal

    I too had to look up 'farkle'. @hevans1944 always does this in most of his posts. I have read the dictionary more times than 'The Art Of Electronics' thanks to his posts... He is stalling me.....:p Martin
