    Simple Wiring Question

    mmmm...well say Honda 750, probably has around the 220w output and different ones have been trying to increase this over the years. Seems around 30w is the maximum they can achieve with major hacking. 100w extra to me seems a bit of a pipe dream really.

    Simple solar charging circuit for two 18V Lithium Ion batteries

    Converters have no limiting factors required for charging (or discharging) such cells. If you have access to a 12v car battery, connect your solar to there by all means but the Li-ion best charged using an appropriate charger. There are r/c aircraft chargers available that will safely charge up...

    PIR LED 12V light circuit recommendations wanted.

    Best get yourself a cheap component tester........worth their weight as they say. I added a hack rechargable battery and charger to the back of mine. https://www.ebay.com.au/itm/154100949483

    Simple Wiring Question

    Yes, my error. Didn't see the (1 way) The actual voltage drop is something you need to consider when connected to your equipment and whether or not the load can tolerate it. In your circumstances it wouldn't matter a toss as it's just heating elements. The only problem would be if your cable is...

    Simple Wiring Question

    Seems it would be around 0.5v drop.... calculator here ...... https://www.rapidtables.com/calc/wire/voltage-drop-calculator.html I'd be using silicon cable as used in rc model aircraft with some form of outer sheath for protection, much more flexible. As far as safe is concerned, only as good...

    Ampere/voltagemeter

    Good idea. Have done that before today in "difficult" situations.

    Op amp comparator troubles

    Output of op amp is open collector. Your circuit does not allow for that. Show the complete circuit.

    NiMH battery pack mystery

    Not unless the cells are defective. Point was, if you read any of the batteryuniversity data on NiMh or Nicads or whatever you would see the capacity is rated at a certain discharge. This may be called C10 or C5 whatever the manufacturer decides. (C5 = 5 hours) So if a cell is has a certain...

    Yes, I was thinking the Op may try to use the micro to sink the LED circuit from 10v.
