    Is this possible to do?

    If it's copper line to the house it is . The telecom company own that and all downstream from there. This is exactly what I was referring to when I said stay out of it. A little knowledge is dangerous.

    Is this possible to do?

    Bridge is a 2A bridge rectifier and (as shown) is made up of 4 diodes. I would imagine this is made for the old style copper line in where on hook and off hook are at different voltages, along with the ring level. Best advice would be, stay well away from any telecom gear. If you send something...

    Motion sensing

    Same pensioners club eh?....:):) I think you'll find your sonic device will have a rather large "viewing angle" , whereas the pir sensor I mentioned can be "blinkered" ( much like an old draught horse in the horse and buggy situation) I have seen some which will actually have small clip in...

    Motion sensing

    Possibly think about using an off-the-shelf passive infrared detector, angled such that it will only detect the top of the bimini. Note that most of these units detect at an angle to the incoming traffic, not straight on as one might imagine. They also do not like direct sunlight on the front...

    Will MOSFET be Replaced in the Future?

    They do a particular job and do it well, so why replace it? I'm just ticked off when the English language gets abused.

    2 mosfets switch

    Resistors are for proper biasing. As shown the 10k pulldown is to ensure the mosfet goes off and stays off. The 100R is for some series protection. The 1K pullup ensures M2 operates correctly. 12v operation would suit most mosfets but that depends on which ones you use and what signal level you...

    12 Battery charger transformer issue/identification

    Transformers don't transform DC. The switchmode transform a high frequency switched dc from the input rectifiers. If your input is solid dc from the input rectifier and filter then there is a problem in the switcher section. The unit needs to be assembled for the switcher to work.

    12 Battery charger transformer issue/identification

    More likely to be a switchmode type by the looks of the opto feedback chip centre right. Cannot say for sure with the limited photo range. I don't see where you tested the primary offhand. These transformers rarely fail, so I'd be looking elsewhere in the circuit. Not an easy task for inexperienced.

    Toyota Order Picker PCB

    Photo too blurry to identify anything but by board marking some kind of capacitor. What makes you believe it is faulty? Did you cut it out or did it fall out?

    Technically it's a high frequency ( maybe 400hz) switched dc on the primary input to the transformer. Can be the chip as they get quite a hard life, but as in many things, not always. Sometimes it will be the associated switching mosfet (if used) or failure of one of the feedback items, rarely...

    One can also learn by reading as we used to in the old days, it's called study. Pick a subject and find as much info on it as you can and go from there. The 5VSB I imagine would be the standby voltage generated by one section of the supply, usually low current. The main supply needs it to...

    repair pc power supply

    Diode legs are usually referred to as anode and cathode, that way avoids any confusion. Photos have the flash turned on by the look of it, difficult to make out any chip markings. Underside view with arrows and red circles, something looks to have blown up there. Also above right hand side...

    repair pc power supply

    Have no idea which diode you are referring to as the photo is not specific. However, normally the characteristic of the supply shutting down would be some kind of short. If testing a diode, lift at least one leg to test otherwise you will get inaccurate results. How did you test the...

    Well, to be fair , you didn't say that. Look for any dodgy or leaking electrolytics.

    Cannot see the output plugs but it looks like an older one given the power output......... So......may be nothing wrong with it, it might just be waiting for the PG signal (power good) That usually entails bridging the green in the plug to black common. Yours might be different though.

    Preparation is important. There are a couple of stages to go through if you want paint to stick properly, especially to stainless. Just use a sticker, plenty of signwriters have offcuts you could use.
