Hi guys and Gals, i am new to electronics (about a month and a half) and have a MILLION questions....., however i am only posting my first problem today !
i have built an inductor based voltage booster with a primary coil of an old transformer, 2 capacitors and a switch (and it works, it actually takes the voltage up very nicely when the button is pushed !!)
So having been so infinitely successful with this major achievement (hihihihihi) here is my problem..............
1) as soon as the voltage appears it disappears ........................(want to be able to preset the voltage and once achieved, keep it there and stable)
2) i am using a push button switch. (to "up" the voltage).............(want the circuit to do the switching, i heard about the 555 and a mosfet)
3) even with high voltage (around 50), it wont turn a relatively small motor....(circuit must produce enough amps or miliamps to run the motor at full load)
4) system must be adjustable, varying from 12vdc (with its given miliamp) to around 20vdc (with its given miliamp) (or alternatively adjustable in a 10 - 15volt range either up or down, with a max input volt of 24vdc)
To put you all in the loop !!, i have a small solar panel (20vdc around 11 watt) and want to use this to power a small electric motor !, currently the battery (12vdc) powers it perfectly, but the solar panel(20v) just doesn't have the juice (even though the voltage is higher)..................
as simple as it can be (regards to explanation and schematics) i would appreciate any help !
much appreciated
