    DIY harness for car amplifier?

    For the number of wires you describe, I'd probably get a 12-position Molex 0.093 connector. There is a Molex generic open barrel hand crimp tool that sells for ≈$40. You need to pay attention to wire gauge when buying the pins.

    DIY harness for car amplifier?

    Of course, it's just that most people don't have or want to acquire the more specialized crimping tool needed for the better connector option nor does the typical automotive DIYer have the requisite skills hence my comment about solder blobs and tape.

    Missing Edit & Cancel Options on Posts

    I've lost the option to edit or cancel an edit on my posts. I tried logging out and back in to no avail. Is anyone else experiencing similar difficulty? The edit option is available for this post so the problem seems to be specific to certain posts. The problem posts behave as if I don't have...

    Kodak Carousel Projector

    The nylon gears used in that line of projectors are prone to embrittlement and breakage due to material incompatibility with the grease used to lubricate them. One symptom of breakage is inability to advance or reverse the tray position. This may or may not be the cause of failure in your case...

    DIY harness for car amplifier?

    What about it? You have wires which you're free to terminate in whatever manner you please. My preference is a crimped pin connector but those short leads that come with your universal connectors are targeted to the solder blob and tape crowd. Many automotive shops sell generic multi-pin...

    DIY harness for car amplifier?

    Automotive applications including to a lesser extent third party audio are notoriously proprietary about their connectors. Consequently, it's very difficult to source matching pieces. As you found, there are some aftermarket suppliers like Crutchfield that specialize in solving some of the more...

    Soldering Help/Button Layout on a PCB Board

    The B in PCB is board. The term 'PCB board' is redundant. What is a pulse and why do you believe that's what you need?

    Soldering Help/Button Layout on a PCB Board

    More often than not, the switches sink an I/O line to ground when pressed. How does dismantling a bluetooth (receiver) help to mitigate your weak coding skills? Is the old radio being used only for aesthetics? What "everything" have you got working?

    Power cord for old knitting machine.

    While waiting, here are some resources. The last one has free service manuals for all models that include enough information to reverse engineer the power supplies. The two 10VAC inputs are converted to ±5VDC and +16VDC supplies with a common ground. The connector types used are not well...

    Must unplug and replug power to make Cooker Hood / Kitchen-Fan work

    That's just a slight variation in marking style.

    Must unplug and replug power to make Cooker Hood / Kitchen-Fan work

    Good catch! That's J0, the motor common. I see heat discoloration on the metal but fortunately no damage on the solder side or at the wire crimp so it's evidence of excess motor current. I also see signs of heat damage at J4 which corresponds to the motor's highest speed (insulation meltback...

    Fridge light

    Try another bulb. Sometimes a filament will break in a way that is intermittent for a while before complete failure. P.S. I understand that it's difficult to create or find a fitting avatar quickly but paint color chips? Really! :p P.P.S. At least you put something there instead of leaving it...

    Must unplug and replug power to make Cooker Hood / Kitchen-Fan work

    After reading your first description, I thought a PTC resettable fuse in the fan or one of the transformers was being tripped and reset and I was going to suggest the same divide and conquer diagnostic method that Ed did. After reading your second very thorough description of symptoms I suspect...

    Hi, have anyebody had trouble building the ELENCO 108 AM/FM RADIO KIT

    Besides correct component per location, the most common error in kit assembly is wrong polarity or orientation of components such as diodes, transistors, capacitors and ICs.

    Tablet RF coaxial cable.

    You didn't say what overall diameter but RG-174 and RG-316 are common small coaxial cables. Others are shown in the Wikipedia article as well. https://en.m.wikipedia.org/wiki/Coaxial_cable

    Wire connection type?

    It's understandable that the casual reader may not read the fine print of every linked item, though they probably should before posting on the thread. It is less understandable that the TS, having the most to gain, would fail to carefully parse a thoughtful response to their query. o_O The...

    Wire connection type?

    I told you exactly where the information is. The first link I posted is a data sheet. Halfway or more down that sheet, the blower model you have is listed in a chart. Below that chart are some notes. One of those notes is headed "Miscellaneous". In the paragraph that follows is a brand (Amp) and...
