    PWM Without PWM IC

    I was writing up a post on pwm after someone said that pwm didn't regulate voltage, and how before and after the filter capacitor the voltage is either 12 or 0V before but let's say 8V afterwards. This gave me an idea about a adjustable voltage regulator that would work sort of like this the...

    Creating a cheaply built (mostly out of slaughtered parts) mppt

    What I need is a circuit That will transfrom my 17V DC into something with quite a bit of frequency, I know if it's a capacitor based solution I might end up with higher voltage spikes, but on the output end I can smooth things out with capacitors again :P so I can feed it through a transformer...

    Relays that stay ? is there such a thing?

    ??? My question to the community is the following is there such thing as a relay that will stay in either in switch 1 or switch position 2 without constant current needing to be applied to either one or two. I mean usually a relay stays in the switch one position and lets current through to one...

    anyone got some ideas for me on these three problems Charger and monitor circuit

    First I need a voltage divider I know that is two resistors but I’m a little unclear on how that would be wired to an adc Second I need a circuit that can measure charging current based on an adc while it’s still isolated from the adc I can’t have the 1 amp going to the adc pin, but I can’t...

    Hello Newbie questions

    Hi guys I'm an advanced computer builder, but I got the small problem in electronics I'm a complete and utter novice, I want to learn how to program and design curcuits based on pic processors, but there are so many factors to consider, I really need some recomendations on how to learn this...
