    Will measuring the resistance of a capacitor damage it?

    What about analogue MM's. They run on higher voltages?

    Thanks! Wow! 2 minute result! How about becoming head of our Inland Revenue Service? Their turnaround time is measured in months and when they're really hot, years

    Is it possible to have the "Upload a file" option in the Conversation section? That would be very handy.

    Car phone charger with AD85063D. Does it deliver?

    I would love to get to that spice diagram to work but to do that I have to insert the IC in there. Is it possible to get that IC into spice.? Or another program like Tina, etc

    Car phone charger with AD85063D. Does it deliver?

    If I read it correctly the above diagram gives 2 different voltages to pins 2 and 3 whereas my spice diagram sends the same voltage to pins 2 and 3

    Car phone charger with AD85063D. Does it deliver?

    Sorry, didn't see the last bit. Very possibly. I'm not going to buy a genuine Samsung car charger just to compare

    Car phone charger with AD85063D. Does it deliver?

    I am also using a Samsung cable to connect it, so just curious why it usually charges at 300-600mA. At 300mA the phone actually loses charge while charging:mad:

    Car phone charger with AD85063D. Does it deliver?

    I am curious about this charger. Can it actually supply 2.1A as stated on the charger? When it was still working it mostly charged at 300 or 600mA. Here is the datasheet application for the charger: And here is the diagram for the actual charger: as I drew it in LTspice. Please be patient...

    fta Sat TV decoder: Need some ID

    Got it so it's running with one red light again. I now want to put it in a cryogenic state with a dry ice block on the heatsink. But while it's running like this I want to check the voltages of all 14 electrolytic caps. How do I do this? Do I put the neg probe of the dmm on the neg side of...

    Would love to try it but it will only happen if I can get it to fire up. When I plug in power now I get two flashing red led's. It did recover once before so here's hoping
