Thanks Bob! It is magic, massively cool! it has sunk in, and as I said earlier, its cheaper too, now I only need to know about those capacitors, electrolytic/ceramicHopefully it has sunk in by now that you do not use a voltage divider as a power supply.
But what is a regulator really? A regulator is a voltage divider with the regulator replacing the top resistor and the load replacing the bottom resistor. But the magic of it is that the resistance of the regulator changes to automatically keep the same voltage on the load.

So the 0.1uF also electrolytic?
You can use 100uF electrolytic it wont make any difference since its there to remove noise.
can't get either of them from my local store, btw how much input current do they need?if you use an lm323k or 74h05 you can get much more current, the lm 323k runs 2 amps, and the 74h05 runs 3 amps. otherwise the same circuit.
excuse my ignorance, but what is C3's unit? then its C1,C2 0.1uF ceramic but what happens to ground, on the circuit i referred to have GND connected to the Caps EDIT: misread sozYou can make it like this:
C3-100 uF
I meant the x on the line coming from gnd, shouldn't that be connected to GND7805 is POSITIVE voltage regulator bottom line is always ground in this kind of designs.
Voltage regulators take very little current to regulate.can't get either of them from my local store, btw how much input current do they need?
Forget the pipe theory.The pipe theory (smallest pipe determines current) and load may use any amount of the pipe
