A lot of guys swear by the M105/M205 combo for quick restoration work. Personally M105 flashes off (dries) way too quickly to me, but it is an aggressive and very linear cut. You just have to be careful, because if you work it until dry it is like glue and leaves marring you have to repolish to...
A few things:
The 3M 39002 is pretty toxic. If you read the label there is a fairly obscure warning that you need respiratory protection when using it. Do so if you continue to (though 1 exposure is no big deal). Given that it is toxic there are better options out there that will get you...
A 555 timer, a MOSFET, and a few various passive circuit parts and you could make a super cheap, super reliable flasher that will drive a hell of a lot of LEDs.
Adding a nice high power resistor should work too, but will waste power. Someone probably already makes the led blinker circuit in a...
Double check your solder joints, they should be shiny and smooth not cloudy and clumpy. That's the first place I would look if you're sure it worked right initially.
You are reading the equivalent resistance of the circuit at that point.
Once you solder them, they become a part of the circuit network, and when you test two points electricity flows in all possible paths between the two points to varying degrees.
You can learn more about the basic...
Take note scott, the best thing my parents did for me was leave me the fxxx alone and let me make my own mistakes and burn my own hand on the stove. What I'm trying to say is your daughter would be better off if you left her alone and her house burned to the ground from an electrical fire.
