    I now only play OPR instead of any games workshop wargame.

    What it lacks in depth it gains immensely in actual fun, I’ve taught newbies how to play in minutes top and the army builder is the best there is.

    The alternative activation means there’s no down time where you’re waiting 30mn to have a proper reaction, it feels fast paced, strategic.

    Hugely recommend it if you have miniatures for wargaming, hell they even have a free starter set where you print 2D “miniature” if you don’t have any.

    Just so you know, as an inductor is just a small coil of copper, the resistivity might be low enough to trigger the beeping on the multimeter! So maybe it’s not dead. I’ve seen a lot of burned down inductor and trust me it looks way worse.

    If your multimeter can measure resistance in miliHoms, you should be able to measure at least ~10mR or more (that order of magnitude) Note that measuring a circuit like so is not guaranteed since there’s other stuff on a PCB that gets measured at the same time.

    Did you remove the motherboard and looked at the other side?

    Wait do you want to have some sort of security camera when not using the car or more something to record when driving?

    Do you want to stream the camera with the phone? If so that’ll take quite a bit more power than you’re expecting.

    If you want to record when the car is sitting idle, I wouldn’t connect it to the car directly as you’ll probably drain the battery (the capacity of those isn’t huge and I bet you’d drain it enough in <10h)

    If you want the phone to be able to record and stream over 2G / 4G for a full week, I would do the following:

    Fully charge the phone, turn off the WiFi, set the app to start the stream, and make it look outside a window. Then check in every hour to see when the battery ran out.

    Once you know it take X hours to drain the battery, look up your phone battery capacity (ideally in WH to get an accurate result, but mAh is fine), and then you can do the math:

    There’s 24*7= 168h in a week You need capacity for 168/X hours (the time it took to drain the battery) Multiply by your capacity C

    So in the end you’ll need a power bank that has at least 168/X*C Wh.

    If you only have the mAh rating it’s a bit more math, happy to help with infos if you need it.
