    Overkill LEDs and PWMing with electric switch

    These are a logic level switched mosfet which will handle quite a bit of current, they are cheap @ $4.00 odd for 10, plus you can use them in micro circuits as well later on maybe. FQP30N06L Look on Ebay.

    LED Celling stay glow.Can I stop that?

    As Shrtrnd says, depends on your electrical installation however, most of the problem like this comes from a rising neutral voltage (above ground). The fix with fluro lights was to reverse the line and neutral connections. Whether or not it will work with the new LEDs and their power supply...

    Temperature sensor

    If you tell us a bit more about the application as your query raises a dozen or more questions about your application. Such as, is the 3' x 3' surface concrete or steel, is the 3' x 3' section enclosed or in a wind tunnel....what range of temperatures are you talking about here .......on and...

    Sequential Tail Light

    Managed to get a "round-a-bout" translation on the pdf data sheet done.....may be enough to get Gryd3 to see what's going on.

    Aluminum Extrusion

    I had an aluminium screen door frame built from this exact same profile. (aprox. 2mm wall thickness.) Made to fit inside an existing exterior door steel frame as used in concrete block walls.

    Sequential Tail Light

    Red angle banana plug looks like its almost broken off... perhaps intermittent..?? could be wrong but it looks like the 2000 scale is for diode test also you have the red test lead connected to the common........

    Use for old circuit boards

    We used to run a wood chisel through everything and use the bare board for control horns on model aircraft. Takes superglue like it was made for it.

    UT61E multimeter - milliamps function not working

    Probably not a good idea. Don't think much of that aluminium foil either. Are you sure you have the leads connected to the right terminals?

    DIY programmable battery charger

    Wire coil on the back of the ammeter is a shunt, not a regulator. Not possible to charge batteries higher than 12v with this charger. Modification would be extreme and given you did not know what a shunt was, then I doubt you could handle building a programmable charger. Better to buy one, most...
