How LC oscillators work with a continous DC power supply
The transistor in the circuit acts like the person pushing the swing. It takes its muscle energy (the DC supply power) and converts it into pushes to the swing. If you have any experience with it wont swing, unless if you let go, but the dc battery is connected directly to the LC witch means current is flowing continuously, so how did it
Feed a "solar" charge controller from AC->DC power supply?
$begingroup$ Thanks, Russell! I did eventually find a few "large" battery chargers that feed off AC (some at rather ridiculous prices). Since I''m apparently not losing much, though, and since A) being able to hang a couple solar panels off it in the future would be nice, and B) I''m going to have a nice power supply in the near future anyway, I think I will indeed find a good solar
