    Why do they use a voltage divider in this instance?

    Sorry HK. The transistor in the circuit hes doing is an amp to make the 12v look like 16 so the LEDS will work. If he removes the resistor, the transistor will fire too soon and the lights won't work because there is not enough power... sorry again!

    Problem with stuck relay

    A diode is a diode, and you have to release it from power to shut it off. A good lesson in grounding.

    automatic forward reverse motor with limit switch and relay

    This is an incredible invention and I am proud to call you an associate on this board, freind. remember, you always want the motor to turn in one direction, and that power cannot travel down two different paths of resistance, only the one of least resistance.

    automatic forward reverse motor with limit switch and relay

    If you want realism and a nice activity you could hire little electronics fairys to operate actual scale models of the equipment you are simulating. But if you just want a simple model, lose the physics and build a VR monitor with 3D glasses that your visitors can put on to enhance the...

    wiring diagram does not match...

    It seems to be working faster than it did... that I would say is a definitive + for operation... Now to crash the freezer room, tear out the sensor, test its resistance, and refit a new one... probably. then, of course, I will probably need to swap the wiring again!

    wiring diagram does not match...

    I re-routed the wires, It registered with the smartthings app but its still doing what it did before!!! that is the freezer temp guage is wrong, and the lights in the lower half are still out... dang must be something else!

    wiring diagram does not match...

    I don't have any interims.... they are an option that I cannot afford right now... Maybe after I get this fridge working properly.

    wiring diagram does not match...

    Are their instructions for swapping wires on CN board connectors for the Samsung SmartKegger? Anything I should know before I force the dingy open and crawl in so I don't drown?

    wiring diagram does not match...

    smart kegger is wired wrong! The skyblu wire and the w/blk wire are reversed... this is a refrigerator defrost sensor, and the CV freezer room switch that are reversed, (that CV room, thats my beer lagering room... very very important to maintain the proper temp!) can't have reversed leads here!!

    General Shortouts and Opens

    short sentence first... a couple connectors got broke, and the wiring connector is gone, so I can't tell which wires connect to which. The wiring diagrm stipulates options on a white/w Yellow wire in the connector. It is a DC door heater. One down, three to go!!! (I think!)

    Modified sinewave to pretty good sinewave?

    About your off grid sitrep---- The type of power you want is power that is created, not power that exists in gravity or otherwise... the day off grid starts between 7 and 9 and requires constant care. "TV and Movies" are considered the 'highest' on the list of un-needed entertainment. You will...

    Modified sinewave to pretty good sinewave?

    Mosfet amps and PWM give off two differn't signal sets... yer sine wave is not such a good idea cause it's not respected as a proper circuit in electronic brain cavities.. If a true sine wave is what you are talking about, well it is a signal that will fry everything if allowed to go on its'...

    General Shortouts and Opens

    Expecting a great turnout for this thread!! I am at odds with this discussion already, so maybe we can lose the rhetorical whoo-haw and just think for a minute. When a short occurs, it usually dumps a bunch of power to ground causing some things the board runs, to just quit working...

    Halogen projector bulb for American DJ effect burns out to soon

    The bulb is a specialized 2 pin mini-projector style bulb 250w. Is there a good replacement that will last longer than a few hours?

    Samsung SmartKegger - Weekends here... Saturdays log 17th 2022 Sept.

    Starting to cool off here. sunshiny day, plenty to do. The device has multiple sensors, and switches.. 11-13 sensors and 4 or 5 switches.. heh! So the freezer temp is right again, and the system appears to be working after a complete halt this morning when I punched in self diagnostics on the...

    Reply to update 'Sensor posting weird, normal operation good, readout wrong. 3-16-22' by 'roughshawd' on item 'Samsung SmartKegger'

    The service manual for this fridge, is written in some kind of pidgeonenglish that is frankly, (even for me) noteworthy of wrongdoing. I would tell the author, editor and officials in charge of its creation, that although I am capable of deciphering most of it, adding clauses at the end of a...

    Samsung SmartKegger - Sensor posting weird, normal operation good, readout wrong. 3-16-22

    Assuming it was the Freezer temp sensor that was bad due to difference in temp from the panel to actual, I returned to the study. The function was at readout 21, that's a proper freezer temp readout. maybe not the freezer sensor. this morning I will check the temps again, and start the...

    Old module does not work

    "It will take a second to think about... hm... you feel like this all the time huh!" ... So a grounding lug us designed to carry the ground from the entire board. usually there will be other grounds, but this ground depending on its size, will carry the majority of the line current. Therea...
