    Homemade capacitor

    Kris, The capacitor you describe made from brass tubes will not have a high value, maybe just a few pF. Does your meter work on such low values?

    RC Frequency scanner.

    Well, I use to run RC cars a lot some years ago. Here we have rules about the frequencies, every frequency has a colour and when you come to a track you put up your colour on the board as soon as you are ready to run. And every radio antenna has a flag with the colour corresponding to the...

    high voltage resister devider

    Steven, If you think about it this way you can rearrange the formula and start over. Sorry for doodling on your picture.

    high voltage resister devider

    Audioguru, Steven, Do you think it would work just by omitting one resistor and use the meter in series as the one hundredth resistor? Presupposed that the meter have and input resistance of 10M which is very common. This way it would be easier to interpret the reading.

    Hi, I suggest junior carry on with his trade business and the next item should be a bigger alternator. I can recommend a 1.7kW like I have, but mine is not for sale! ;D ;D Best Regards to Junior

    Hi, This means 100mA maximum and less if the voltage is high. But yes the draw is less and it

    File types and sizes

    Suraj, Thanks for the suggestion but in this case the file extension was the same. I am sure because I used the same program (Win2PDF) to split the file the first time as when I spitted it in five parts the second time. Sometimes I have been denied uploading a file because

    MosFet

    Thanks for trying Dazza, I am stubborn and I have tried anything I can think of but to no avail. This is a hard nut to crack but John is the best in this game and if given time he can find anything. This mosfet is part of a 80VDC to 3-phase inverter/motorcontroller and quite new (2000) so it can

    LM317 Variable power supply

    I can only speak from my own experience but often I use the LM317 for small things that uses in the range of 10 to 150mA. And if planning the circuit well, a heatsink is overkill. I mean I don

    117L7 tube test

    I am sorry to hear this Mike. What range is it suppose to have, a lot more than 30 feet I guess? Can you post the schematic then maybe someone can assist you. Have you run the new tube in the tester? It is possible that they have made a series of bad tubes.

    LM317 Variable power supply

    Yes, another transistor and a current sense resistor and it works. It will still be much cheaper. Another possibility is to add a fuse or a circuit breaker, it requires manually reset but it
