    value of learning vs value of meter

    I need a capacitance meter and I have found some, that are what I want, for sale. I also found a kit that makes one but it is not really what I want. My situation is that I would like to keep my hobby a hobby, but my skills honed nicely. I think I want to buy one because the kit doesn't...

    transistors, and capacitors

    A transistor is basically a capacitor with an attitude. Rather than open after it heats up a little, It refuses to open unless power is supplied to the base. Same basic deal, different application conditions. I have a cheap Harbor freight multimeter, with NPN and PNP testing capabilities. It...

    Hp laptop adapter fail

    check the wires. the wires sometimes break on the device end, and have to be cut and spliced. I had one that was busted on both ends., I had to rewire the plug and the board. There is alot of white pucky in there. That's quite a bit of white pucky. Might call it a pucky covered mother!

    Restoring a Regal Do-Wa-Diddy by fOXX

    This is a pic of all the wiring pins and their connectors that I assume are wrong. It still doesn't work, and I have worked so hard to get it working, I just can't stop until I've got it. The blue wire is Pin A to the treadle. There is no connector on Pin B-PinC which are bridged and I put A...

    Ceramic Disc Confusion

    I went to the library, I got a book on electronics for inventors, and a book on electronics for hobbiests. Great for me, whoopdy doo for you. Each book had a chart in it, that gave capacitor code reading a whole new meaning to the word confusing. One was fairly clear, It has little pictures...

    Restoring a Regal Do-Wa-Diddy by fOXX

    I have an idea.... just an idea. The resistors at the second transistor 10k and 1k are active when the 22k resistor fires. Because 10k + 1k + 22k = 33k, the 33k resistor becomes inactive in this condition, shutting down the inductor until the treadle changes the resistance, creating a trickle...

    Pavilion 560w MB w/bulging caps

    Wow.. ESR.Hey it would seem that maybe thos caps are using up some of the higher ripples on start up and if the volt rating was changed, it might effect the entire system with some of the ripples because they are burning up some of the current as they fail/and recover. ESR... wow. So even...

    Motherboard repair help

    have fun! I have found that most shorts are caused by something metal wedged between the mobo and the case, touching a hot or even a wire connector. even a hair of copper wire, or a spit ball can cause this stuff.

    Pavilion 560w MB w/bulging caps

    dubious of you steve. thanks for keeping me on track. I did an ebay search and found the exact match caps for a mear 10dollars. Well a lot of 10 anyway. I don't think I will find the same MOBO anywhere, its out of an HP Pavilion from the 90's, and after doing a MOBOcheck online, even if I...

    Pavilion 560w MB w/bulging caps

    nichicon 3300uf 6.3v H0149 105 degree-- total of 9. The computer has been acting up for quite some time. I had checked it about a year ago, and the caps didn't look that bad, maybe a bit bulgy.. So I let it run and yesturday.... no monitor. huh. Where can I get some of these 6.3v 3300uf...

    Motherboard repair help

    I really hate to sat this stuff. I have found from past experience that motherboards are extremely touchy when they fail. It is easier and less costly to replace the motherboard than to try and find a bad component. Most are assembled by robots and trying to second guess their circuits is...

    cheat sheets

    What impresses me with this is that it is 1.5v, and in the case of costly 9v pervasive boxes, there is a real nice bill or two in the folding money after purchase. Don't know how long its gonna last though!!!

    Restoring a Regal Do-Wa-Diddy by fOXX

    After completeing the change from the treadle out to the common wah out, I noticed that the wah has 3 outs, the common to the output and pins G. The last terminal is grounded to the case, as I understand you require a spare grounding wire from the lug to the pin H on board? This would ground...

    Replacing an electrical ballast

    One thing about ballasts.... if you can find a ballast that has the exact specs but different wiring, its if usually safe to rewire it and use it in your light, but remember THE EXACT SPECS, if any of the specs are off, it won't work, or it will blow up or leak or just sit there and buzz.

    cheat sheets

    AS I sit here on the verge of collapse due to idiocy and ironic turmoil... I ponder the great one whom sits for hours toiling upon ways to simplify their performance, fine tune their considerations and just make everything easier. I asked myself..."I wonder if there are any great engineers out...

    Resistance and Inductance

    Dad used to grill me on fractions... I new already that 1/ a number was not 1, from working on lathe calculations in the shop. Removal of zeros is part of machinist, and was a small part of pre algebra. I had heard the term "polish calculator" before, but I have to be honest... the first time...

    Resistance and Inductance

    Calculating resistors in parallel--- count the number of conductors - "duh... I got like 2 resistors in there" 1 divided by each resistor value and add them together. (remember to convert all your values to the same value where ohms is king and the polish are itallian) so 1 / 100000 =.00001...
