    ID a motorola diode

    Knowing the context of its use would help as generic replacements are often easy to identify and source. Got pics of its location on the circuit board?

    Triac Question

    The capacitor readings are within 10% and probably better than the OEM spec anyway. As for the fact that they are electrolytics that's even less of an issue. No one I know uses or requires greater accuracy for electrolytics than the 10% rule. ISTR the standard spec for electro's as being +10...

    Need help w/ home stereo

    I'm assuming the speakers weren't part of the Pioneer original setup? The 400W rating is probably for the whole amp electrically. This might equate to 2x100W audio output. If it is a rating of actual AUDIO output then such figures are more than often exaggerated beyond belief. For a garage...

    Home Based Income as an Electronics Hobbyist

    What 'gets' me though are those places in movies when they claim they are sending/receiving morse code - obviously I can read it and they very, very rarely make sense. Sometime there are fake characters sent! Or the good guys receive 'some' morse code (about three characters) and they make a...

    Famously - well, in the UK anyway - there's a detective series called 'Morse' (the main characters name) and the theme tune to the program actually spells out 'm-o-r-s-e' as it plays.

    Help to identify/replace component

    If it's a typical lithium powered device then the current consumption can be enormous, limited only by the internal resistance of the lithium cell. The MOSFET is actually rated to carry 162A !!! (650A when pulsed!) so needs to be the proper replacement...

    Old Car computer (ECM) may be faulty

    The other contacts are only 'tinned' anyway so you could use a soldering iron, flux cored solder and 'whet' the exposed copper pad to recover it with solder. If you don't feel confident with doing this - and there's a risk of the copper track lifting if you apply too much heat - then see if you...

    Old Car computer (ECM) may be faulty

    Cold solder joints are rare on ECUs - my experience is that they are much more reliable than most manufactured boards as they are designed to work in harsh environments. A quick 'scan' of the image provided shows no particular issues that I can see and trying to check EVERY soldered joint is...

    Year 2038 problem.

    Being more practical and less pessimistic.... if you're still using today's technology in 2038 then you perhaps deserve the problems this issue might pose. Somehow I reckon they'll be developing workarounds well before then.

    Sheeit.... I actually TAUGHT electronics to degree level for seven years and I can barely recall most of the theory! That said, I've always understood that in order to fully understand 'any'subject you have to be confident in being able to teach it to others. (not that you actually HAVE to...

    UT61E multimeter AC measurement issue

    Dud main IC then. Does it 'zero' with the leads shorted? Does the reading change at all when the AC input does? If so, does it follow a linear change?
