  1. gentlywiringit* replied to the thread Hi and alternative mosfet help.

    So this project went on the back burner for a while.. :meh: Pleased to say I have managed to piece it together slowly and now I'm almost...

    30V 10A 110V Precision Variable DC Power Supply to find short to ground(sort of newbe)

    I am trying to find a short to ground in a battery backup and surge protector and I saw a video on YouTube [MEDIA] where the guy placed...

  4. ronsimpson replied to the thread Capacitor help.

    Here is a picture of a spiral cut film resistor. The resistive mater is cut to make a long thin piece. [IMG] A ark arrestor is made...

  5. ronsimpson replied to the thread Capacitor help.

    I think it is a spark gap / ark arrestor /voltage limiting/ thing. I find them on telephone equipment to limit voltage (lightning)....

  6. ronsimpson attached a file to the thread Problem with Battery Balancing Circuit.

    Here is one with a transistor not an op-amp. I am getting 2.4A. [ATTACH]

  7. cowboybob replied to the thread About energy efficiency.

    On that we are in total agreement. I didn't immediately pick up the"tongue in cheek" aspect of your post. I've been dealing with idiots...

  8. cowboybob rated spec's post Agree in the thread About energy efficiency.

    CB, I was playing devils advocate and, as you probably may have realized, this is one area that I consider to be full of snake oil, at...

  9. RogerSLO replied to the thread Neeed some help with dual PIR sensor circuit.

    Hello Eric. Thank you for clarification of direction sensor sensitivity. If I want to use 5V input (for other project), what do I need...

  10. atferrari rated Nigel Goodwin's post Agree in the thread binary coded modulation.

    Rather a bizarre link then :D PIC hardware PWM is usually up to 10 bit, so 1024 levels.

    I've now got a full write-up on the tesla coil circuit. Thanks!...

  12. spec replied to the thread LM723 based PSU with min voltage of 0,00V.

    The diode is in series with a resistor (or two depending where the voltage output photometer is set) so the maximum negative voltage...

  13. spec replied to the thread LM723 based PSU with min voltage of 0,00V.

    You just don't care- do you.:D Quite right, nothing else should be damaged electrically, but you may have a caustic liquid splattered...

  15. earckens replied to the thread LM723 based PSU with min voltage of 0,00V.

    Hi spec, what if I leave the elco, and let it pop when reverse voltage is applied? What else can get harmed? And I would get an auditive...
