hi, i was following this circuit http://www.csgnetwork.com/ne555c1.html and i think i know how it works... but i'm not sure if it generates enough current.
I need -5v for my 4x40 LCD, so far i've tried this circuit using slightly different valued resistors and capacitors and so far it works, but it doesn't charge/pump fast enough. Is there any way i can enhance this circuit to be able to supply more current using common parts?
