    Help wiring in 6A dial into Western Electric 302 rotary telephone

    Maybe you have it wired correctly but the dial is out of calibration. When the dial is back to its resting position, it may overshoot by a fraction. Check the mechanism for anything slightly bent. I have never played with one and am guessing by your description so apologies if it’s BS. Martin

    Wi-fi door to let squirrel out of my basement

    Your new 3" hole may let the critter out but 'it' must know another entrance and exit. It must be going out to dine or your basement is a preppers/squirrels paradise. Not being able to make something is your major disadvantage. I would suggest a simple 'one way' exit only!. Imagine this: A...

    Light/outlet remote status indication

    Have a look at the X10 home automation system. There are better up to date, modern systems but I love the X10 protocol. It’s simple, straightforward technology that doesn’t need a degree in AI. Martin

    I don’t understand current source in a power supply.

    Adding to the above posts. You have to set the current limit yourself. This is (probably) achieved by shorting the power supply leads and setting your desired current limit. Some of these PSU's require a higher voltage setting first in order to set the current limit. Example: Set voltage to 5V...

    DMM Showing Current without Current Source

    What is the problem? Are you having a flat battery after a day? Or 3 days?. What vehicle is it? year? Newer model cars have 50mA or lower after it goes to sleep. 100mA is excessive but not necessarily a fault. Martin
