    Schematic question ...

    I'm getting 25.8 vdc from the negative transformer output line, through the first diode out to the second diode. But I am not getting anything through the second diode. But that's good for my experiment, down from 37.8vac straight off the trans secondary. If I split that with a voltage...

    Schematic question ...

    Hey I think it's coming back to me... Everything in the mains is negated and the sequenced output is gotten from the C-tap. It was signal until AnalogKid got his hands on it !!! then everything went sideways....

    Schematic question ...

    OK I also need to know if I have a component such as a diode, does the polarity change when it goes through it, or is the diode immune to polarity because it allows the pass through? So if I have a resistor where +-----VVVVV------ then - out here... is a diode subject to the same foop...

    LGS4056 Not Working

    OK a little bit of ideal crusade here... The temp pin is a sensor, that is supposed to detect a temp rise in the battery when its either overcharging, or full, but the idea of charging a battery based on its heat signature seems to be a failing system. Good idea. Looks like it might have...

    Schematic question ...

    Just to keep the line open...This was posted on the web as a "center tap recitifier". The image however, is missing the tap... Uh- OK! I would consider the ground to be where the tap would connect, and that the circuit load at Vp(out) would also be part of the the ground buss, as it isn't...

    The diodes were cooked... No telling what rating ..

    Schematic question ...

    I think it's a 120vac to 35vac and the supply was rebuilt in the early 70's by a communications shop on an island in Alaska. It worked when the ambient temp was very low... I moved back to civilization and it overheated... The transformer tests at 35 v in the secondary. Fused 120v US source...

    Schematic question ...

    I see what I did.... The negative changes to positive when it crosses the diode... Oooh how'd it do that??? Ok, but aren't bigger diodes used to replace ones that burn up? I think the transformer is bigger than the diodes could handle.... So they cooked???

    Schematic question ...

    My PSU is a simple AC to DC voltage dropper that employs a transformer and a few transistor and some rc. The transformer is center tapped, and the schematic I got for it, shows the tap as grounded, and the circuits divided with a 200v 35w cap. I'm increasing the amperage capabilities of the...

    Antenna conversion

    Cb whip I think. I clipped a bnc connector on the little 2.4g antenna, and I get a signal from the shop, when the bnc connector is stuck in the aluminum window frame... There is a mini yagi build on you tube, but the weather antenna download on the NOAA site doesn't work... So I am skeptical.

    Antenna conversion

    This is the shop roof in the distance, probably 300' past the building in the foreground. The receiver is too weak to get the signal. But I can put one out front, and the signal is good, but a small bit noisy. Happy Halloween!

    Antenna conversion

    I have a small security camera system that is incapable of sending the signal from my shop to my residence. Can I convert the antenna to a 50 ohm marine whip, the camera will work in my shop too?

    Insulation or bad cell???

    6v 1800ma canan a1 digital movie camera battery pack. Is this a bad cell? There in one pic that looks good

    Mercury 80 throttle.

    I don't waffle! The original switch doesn't exist any more! There is a big metal block in the boat throttle that barely contacts the little switch. The switch is a neutral switch. It turns off, when the boat is in gear, keeps the starter from working when it's not in neutral. I grew up...

    Mercury 80 throttle.

    Those are 250v 125v AC switches that handle about .4 of a pound click hammer. I need some that size...to fit the mounting, that will handle about 6 pounds of hammer.

    Two days later, still really purple. Kind of throbbs off and on... Looks like a darker cathode ray tube...
