  • Re: Different Kind Of 3 Way Light Bulb Switch

    Received socket today and replaced it... took longer to post these pics than to do it, lol.

    Nothing special involved, screws, middle terminal is socket for each bulb, AC neutral, and the two opposing side terminals, one is AC hot and the other goes to the other bulb socket center conductor.

  • Re: Sunpower RPS-2600 pinout?

    If you're saying that it has 12V output for 10 seconds then shuts down, I would guess that you need to put a load on the major power rails to keep them all regulating within tolerance. For example the 5V and 3.3V if present, see if drawing an amp or two from each works.

  • Re: Harman Kardon AVR5 starts, clicks, shuts off

    On your second (middle) picture, below the large caps and to the right is what looks like a relay, next to the small transformer. Maybe it's a film capacitor, check the markings on the side if visible or # of pins as a relay will have 3 or more and film cap usually only 2. If a relay, that should be what is clicking as a protection circuit because something is shorting out, so it's just a symptom, not the problem.

    Most likely it's one of the transistors on the large rear heatsink or one immediately before it in the circuit....

  • Re: OBH Nordica DC adapter

    After repairing something like this I cheat and drill an array of small vent holes on a drill press, with the PCB out of course.

    I slap some masking tape on for contrast then a ruler and marker for a nice even grid for hole placement, then barely touch each hole with a larger bit to chamfer the edge, remove fuzzy plastic remnants.

    Not recommended for wet areas or if you have small children that like to electrocute themselves.

  • Re: Different Kind Of 3 Way Light Bulb Switch



    Yeah but this is a fancy antique lamp with its own matching stem handle that screws onto the switch shaft in place of the original plastic one. I thought about converting it to a capacitive touch lamp but decided cheap, quick, and easy would result in me more likely getting it back to the owner soon instead of shelving the project and forgetting about it. Besides it still needs a new socket even if it had capacitive switching. I tore the old one open to see if it was refurbish-able but it was just too worn out.

    ^ No you had it right the first time. I bought the PLT 90-421 that I linked on Amazon. Oddly 1000Bulbs sells it with $2.29 shipping on Amazon but wants $10 shipping if ordered direct from their website.

    Leviton also makes one that looks right as # 07070-0PG

  • Re: Different Kind Of 3 Way Light Bulb Switch

    ^ Yes. I need it to do that, and have a rotating side stem switch like this:

    [url]https://www.amazon.com/gp/product/B002DN4LX4[/url]

    If it comes with the exterior shell like that one at amazon, it'll have the (1/4"?) threaded mount on the bottom that is needed, or I could reuse the old exterior shell if I found the interior switch/socket assembly sold separately.

    Previously I wrote E27 but I meant E26, need E26 socket.

    Did some more searching, found a lamp repair site that stated...

  • Re: Different Kind Of 3 Way Light Bulb Switch

    Not relevant. I am asking about 3 way where the 3rd way is a separate bulb ( circuit ) instead of a separate ring on the same bulb socket. Whether it is LED or not is irrelevant, but yeah, it makes sense to make both bulbs LED.

  • Different Kind Of 3 Way Light Bulb Switch

    Fixing a lamp, I have a strange light bulb socket, at least strange to me.

    It's a 3 way but not to a 3 way bulb. Way one, primary bulb on. Way two, second base bulb lights up but not primary. Way three, all off.

    It needs to fit standard (1/4"?) lamp post pole threading and take an E27 bulb. Am I just not using the right search terms? This is replacing a failed (worn out and severely corroded) socket that does not have more than a two way bulb contacts in the socket.

  • Re: Computer fan noise and maintenance

    Unfortunately I'm finding more and more cheap fans that are permanently sealed, no lube bung and have some kind of press-fit assembly. Some are even semi-popular brands like Coolermaster and otherwise appear to be fair quality for their low price.

    Some day if I get bored enough I might try drilling a little hole to lube one, but I have plenty of other fans so am in no rush to bother.

  • Re: Computer fan noise and maintenance

    I've washed fans before just to get gunk like tobacco tar off the blades and frame, and didn't disassemble them at all, just shook excess water out and set them over a HVAC register if I was in a hurry or just sitting on a shelf if I wasn't.

    The main thing was to just wait until I felt they were dry before applying power. Never had a problem doing that, though I didn't leave them soaking in water, just sprayed Mr. Clean on them and a toothbrush to loosen gunk, then a brief rinse under tap water. FYI Mr Clean is a lot better at...

  • Re: Computer fan noise and maintenance

    Graphite is cheap, if it worked then that's what fan manufacturers would use from the factory.

    Practically all of the sleeve bearing type use a sintered bronze bearing which has pores in it. Due to this you want a thin oil base that is absorbed into the pores, and a longer chain grease suspended to make up for the excess play and keep the oil in place so more of it has a chance to soak in.

    No fancy lubricant additive is needed. It merely needs to keep the shaft from wobbling around, pumping out the lubricant once there...

  • Re: 18 volt drill power supply.

    First, it's entirely possible that the transformer's thermal fuse has blown but only due to a temporary condition. Put the transformer on a heat resistant (fire-proof) surface, put a new thermal fuse on, and test for overheating. Using it in a hot area, bits of drilled material or dust clogging inadequate vent slots in the charger casing, it happens... clean it up and drill some more vent holes if the transformer seems okay with a new fuse.

    However, an 18V drill doesn't necessarily have an 18V transformer. 18V is just the nominal voltage...

  • Re: Infinity PS-12 Powered Subwoofer Fired Amplifier

    four3rds, yes that's just glue that turned brown from heat. The way they put the shrink wrap on some caps that size, with the plastic disc on there it makes them look a little domed on top like bad caps get but that's usually just the plastic disc bulged up, not the metal under it.

    Trying to describe from scratch how to trace an amp is really beyond the scope of a forum post but basically you whip out a multimeter and see if the right voltage is getting to the output transistor(s) or power pin on an output IC....

  • Re: Why 19v adapter on laptop when they run on 12v

    First off, laptops don't run off 12V. Some batteries are 14.4V, some are 10.8V. The difference is 4 x 3.6V Li-Ion in series (and sometimes 2 series in parallel) for 14.4V, or 3 x series for 10.8V.

    Nothing in the laptop even needs that, unless they happened to pick a 12V fan. Make fan 5V, optical and HDD run off 5V and 3.3V, practically everything else even lower voltage (with exception of the fluorescent screen backlighting tubes in older models), and the voltage is just higher to reduce current until right before the...

  • Re: Zyxel PSU

    1) I am assuming you have a zyxel network switch that stopped working because the power supply for it failed.

    Any of those 3 capacitors you linked should work, but I wouldn't get the Rubycon because it's excessively priced. It does not need to be an AC capacitor as it is rectified to DC by one or more diodes before that capacitor in the circuit,but this should be obvious by looking at the original capacitor, looking up how it is rated.

  • Re: Choke/coil/inductor: replacing or measuring

    You can probably get away with just cutting the heatshrink tubing off, inspecting the windings to make sure they don't "look" like the enamel is burnt off to make any shorts, then unwind a winding or two to get enough length to strip and solder it back to the board.

    Once you've done that if you have no suitable replacement heatshrink tubing, fold a piece of cardboard around it and tack the component and cardboard down with silicone caulking or epoxy or whatever you have that's reasonably heat resistant.

  • Re: To be -5v, or not to be -5v? That is the question

    Some OEM motherboards and aftermarket (Creative Labs for one) sound cards had audio amp chips meant to direct drive speakers, also made use of the -12V rail to give 12V/0/-12V supply.

    Back to the original question, if -5V is connected to the board but not required, meaning not used, there is nothing it could damage. There is no ATX compliant motherboard which will have a problem with -5V being present on the corresponding PSU connector pin, not newer or older it makes no difference.

  • Re: AC Voltage Stabilization

    Get the pump motor manufacturer and model # info and ask the manufacturer what the most cost effective way to manage that is. Possibly you need a different motor or entire pump more immune to the dips.

    The flywheel idea is interesting. At first I was thinking an active generator style flywheel but then I thought "What if it's possible to just put it on a pulley or gear on the motor shaft?", although you might then need a second motor to start it so it doesn't burn up the pump motor and then if you're going to do that then you...
