    An unidentified component

    Hi Aron, welcome to EP. Does it have 3 legs, I can't see that clearly from the pictures? If it does it could be a small auto transformer. What is the device it's out of? Adam

    newbie question

    I think most modern lamps like this use the solar panel as the light detector as well as charging the battery, but I might be wrong. You may also need to find out if the circuitry inside has a little boost convertor to take a single cell battery up to a voltage high enough to drive the white LED...

    current flow in earthing point problem????

    Yep. But not just the insulation resistance. Every mains filter that has a connection from live to earth (Y type capacitor) will inject a current into earth. This is why there is a maximum value of capacitance, so to be below the 30 mA trip value. But some equipment like a LISN (line input...

    current flow in earthing point problem????

    Current in the earth wire happens all the time, it's the amount of current that's important. Adam

    You going to tell us the error then? The mind readers aren't online today.

    What about a drill with variable speed and a wooden bobbin?

    Dimmer for 12volt AC LED strip

    Yeah the dimmer looks good but it does mention certain LEDs I think, maybe just marketing stuff. Give it a go, I will be interested how you get on. Adam

    Guitar pedal customization

    I'll see if I can find the website I used to use that had lots of circuit diagrams for pedals.

    Dimmer for 12volt AC LED strip

    It depends on the power supply you use. The resistor will dissipate some of the energy as heat thus reducing the amount for the LEDs. If you use a switch mode power supply then this is more efficient than using a resistor. Both options will accomplish the same thing at the end of the day.

    Dimmer for 12volt AC LED strip

    I assume 12 Volts will produce maximum brightness. What about running them from say 9 Volts? Adam

    Guitar pedal customization

    You could use a variable resistor or a cheap resistance block like this to try some different values. It would be good to know what current the unit draws when in use. I think it's quite low, I never measured any of mine when I used to play guitar. https://www.sparkfun.com/products/13006
