    Ticking sound and won't start VCR

    That video was really vaige... make sure you don't have one of those overloading psu manufacturers in there too!

    buggy board, bad tech and strange readout... heh heh

    One other thing, can I test this board out of the fridge using a digital oscilloscope/multi-channels or is it one of those handheld passive sets that cost a grand or two?

    buggy board, bad tech and strange readout... heh heh

    That's not what I learned in my basic electronics class. The actual ground is whatever ground is used on the board to handle the signal... Like if you have a 5v signal, you have to use a 5v ground or the signal feedsback. Now I know there is a such thing as a feedback circuit, but I don't know...

    Tumble Dryer Heat pump problem

    So locking wet clothes in a small freezer is not a good idea huh??!!!! Anyway, it sounds like a sensor problem, but todays electronic equip doesn't read the sensor value, it computes it for readout. That means that even if the sensor is going up and down, that the readout will only display what...

    buggy board, bad tech and strange readout... heh heh

    Is that probe grounded to the board, or the case of the fridge, or just a divergent idiot on the business end of an oscilloscope?

    buggy board, bad tech and strange readout... heh heh

    This is a pic of a stamp on the board it says Sensor CheckPoint and its numbered 1 through 13 for the individual sensors on the board. It is next to the 20 pin pinout next to the micom brainiac central processor chip in the middle of the board. note for dedicated fans... Arduino on steroids.

    buggy board, bad tech and strange readout... heh heh

    I would be probably better off just buying a new PBA and put it in the fridge, but I feel so close to fixing it!!! Everything still looks good, in fact the readout seems to be running better than it did before except that the sensors are not proper, and read out -8 degrees while the Wi-Fi tells...

    diagnostic port on smartkegger control board.

    I was considering a complete change, building new boards and creating new and exciting programs, but the world just isn't turning that way. So there is a "short cut", what I usually call a ' short stack ' that should be a good option but there's no one who knows private business tech... Except...

    Fridge compressor test....

    PBA is not bad. Magnets placed under the doors make the accessories work, but in connecting to be wiring, I am not sure who's way is proper. The freezer is connected in series where gray wire is common or ground. The CV or lagering room is not connected series, where the colored wires are...

    Assuming your repair has 4 terminals for a two blade ac cable from 110v-120v wall plate.. ac1 ac2 ac3 and ac4. It has further two cable's with a switch in it. The slang being "always switch the line not the load" I have to think that the load is the terminal that has the switch in the cable...

    PSU transformer repair completed

    optional ducktape method! notice the extra backing used to maintain board integrity and proper function of the repair... Can be optionally removed by specialized technician and allows a holder so you don't get shocked if you are a novice.

    PSU transformer repair completed

    When I was fixing the J2 jumper, I lost hold of my tweezers and it flew away to where old jumpers go when they die. I replaced it with a solid copper jumper that solders directly to the repair strap. What should I use as a filler to seal the repair?

    PSU transformer repair completed

    One other small thing!!! There are supposed to be 2 red leds on the button board. They have long since been smoked. They sit atop little towers that lift them up. I am assuming these are 2007 era red LEDs and they are probably the standard small factor diodes. the outside led is activated...

    PSU transformer repair completed

    I have an old psu from some thing that was put in the operating pile in 2007. It has a two button, momentary interupt (gel button) board that plugs into it which has some kind of action that it is supposed to perform when the device is turned on with a second, push to activate - positive on...

    matched impedance question

    They are rca but I remember reading something about the video connectors on the RCA plugs being a superior material so there's less noise.

    matched impedance question

    I don't feel right spending 22 dollars on two little connectors, it's not American! So I have taken apart a video cable and an old VHS player that doesn't need them any more. There will simplify the connection, and should give smartkegger adequate signal to the board. Are the skinny video...

    matched impedance question

    The panel was staying lit all the time. with stronger magnets the door alarm silences and the lights in the freezers operate properly. I need two(2) 2 pin connectors for the doors, my wire nuts should be replaced with suitable connectors. The refrigerator is not reading properly now. it is...

    matched impedance question

    I will try stronger magnets and see if the lights turn off when they are applied. There is something funky with a set of switches that appear to work backwards...
