  • A relay switch could work. You would put the car 12V and ground across the coil connections, the 12V on the NO connection, the panel on the NC connection, and the power pack on the C connection. Make sure you get a 12VDC relay.

    Are you going to have the panel installed permanently on your car?

    Definitely don’t connect a 24V source directly to your cars 12V system. There’s a good chance of frying something important. A fuse would not protect from overvoltage so don’t rely on those to protect components.








  • 4 times in the last 5 years.

    There’s a combination of flaws. The strainer basket doesn’t do a very good job keeping debris out of the impeller. There’s little separation between the steainer and the impeller. So long hairs that are partially caught in the strainer can still wrap around the impeller.

    The pump itself has a terrible impeller design. The impeller is nylon and is press fit onto a 1/8 brass rod that just has a flat ground on it, no knurling or splines. The nylon cracks easily and ends up free spinning.

    They use the same pump in loads of washer models. So yes, there’s a very large user base, but that’s a lot of people with part failures. The pump is garbage and lg should not be using it.





  • Maybe for someone with a specific baking recipe in mind? One of the egg noodle recipes I like calls for about as many extra yolks as whole eggs. So I could probably just use these without waste or having to make a separate recipe to use up the whites. I’ve never seen this at stores near me either in the US.







  • I could be wrong, but I think XRD requires very pure crystals of sufficiently large size. That can help you ascertain the structure and composition of something you can synthesize and crystalize, but I don’t believe xrd can image specific regions of interest like single doping sites like this article talks about.

    Synchrotron XRD also has a major drawback in having a very significant equipment requirement that requires being able send samples away for analysis at a dedicated facility. That puts limits on sample preparation and stability time, as well as sharing beam time with lots of other groups.

    It’s been a while since I’ve read up on synchrotron xray diffraction though, so there could be workarounds for some of those limitation or I could be misremembering details.
