    [moved] led problem wont light up anymore

    What is your meter set for? Voltage or Resistance? A buzzing noise is usually reserved for continuity setting. So are you sure you are not reading .010 Ohms and not Volts? Especially as you say the module is removed from the bike, there can be no voltage. If it is ohms, you have a shorted...

    [SOLVED] dummy load on old computer power supply

    In my experience you just need to take the green and black wires and tie them together, as they are the "On Switch" wires, and it should fire up just fine. Yes, some switching power supplies do have a minimum load, but all the computer supplys I've checked just need to be switched on with the...

    Are you speaking of a RGB LED?

    [SOLVED] 2way active speaker sounds distorted

    Hi 5inc, "When you do reballings, do you **** out some solder before you apply new one?" On most Reballings, you can't **** the solder out the other side. "****" is not a dirty word, it's what life often does. 8-) Even when you can **** out the solder, you could never reapply the solder through...

    what is diierance between electrical and mechanical tilt

    Would you mind expounding on that question?

    directional dependence of antenna gain

    "do we measure the antenna gain all direction and then simply take the directive one as the antenna gain." I'm pretty sure on directional antennas that is the convention.

    directional dependence of antenna gain

    Good question. If it is a directional antenna, common sense would dictate that at it's highest gain would indeed be the number used. Just like you would only use the Gain directly in front of a parabolic, as that is the one (and only) you care about.

    [SOLVED] 2way active speaker sounds distorted

    5inc, Glad you found the problem. Congratulations on your tenacity! You didn't even need to order a part! Production problems are the hardest to find, because you have to start with the assumption that it was at least built right. By the way, I looked at the Spec sheet for the IC, Monolithic...

    [SOLVED] 2way active speaker sounds distorted

    Guru, who cares if YOU think it is junk? It works for him. That is what matters. And almost everything can be repaired. 5inc, Does it use an integrated amplifier? You know, a power IC for an amp? If so, 1 or 2? (left and right or 1 mono) If freeze spray did not fix it, (temporally of course)...

    [SOLVED] 2way active speaker sounds distorted

    Audio guru gave a poor opinion, no help. Your friend doesn't know what he was talking about, randomly changing parts never works. Bridge rectifiers are not high fail items, or subject to being intermittent. If it was a intermittent bridge rectifier, it would put out a 60 hz loud hum. A problem...

    What is the absolute maximum supply voltage spike withstand of ASICs?

    Rather than your question, I would be asking myself what can I do to tightly control the power supply output, to the point of taking extreme measures. Only the manufacturer would be closest to being able to answer your original question, as they know how it was built. But, use ACTIVE...

    Can't find the datasheet/replacement of this IC

    Any chance it is the part below? I dropped the IL (manufacturer) and 03 suffix As is so often the case on old parts, they want money for the data sheet. -Lisa APL1088EC-PB Datasheet Datasheet for http://chipmanuals.com/datasheets/search/go/ Description: 500mA Low Dropout Linear Regulator...

    Charger for 1.2v NiMH battery without contact

    Capacitive coupling is out of the question, if you knew the surface area, and plate proximity of a 1uF cap, you would understand what I mean. If you want, Sacrifice a 1 or 10 uF cap, carefully take it apart with gloves on, and unroll the 2 plates separated by the dielectric. You will get the...

    16F877 thermometer problem

    What caps and crystal are you using, I know the caps you originally had were actually shorting the clock signal to ground they were so large. It is possible your clock is intermittent if you don't have correct values, also different brand/ type crystals require different size caps. Do you have...

    Charger for 1.2v NiMH battery without contact

    In the original post he described the it as a phototransistor. I stand by my conclusions, it would not be very efficient to use a photo cell especially if it is not at it's best at that photo DIODES wavelength. A motor with neodymium magnets would indeed work , but be very tough to balance...
