Heh, by on the go, I mean mobile application. (I admit, I have no idea how to do this, stationary or mobile.) I'm trying to wire LEDs to the underside of an umbrella. Kind of counterbalance the dreariness of days that warrant umbrella use.
I was ready to use three AA batteries as the power supply but that's a little bulky for an umbrella - especially when you go to close it. Google became overwhelming.
I read about operational amplifiers, transistors, NPN, transformers. Those all sounded very similar for my particular case. An inverter, a Cockcroft-Walton ladder.. no idea. A charge pump did sound more promising for this project. A switching regulator, DC bus, oscillator, etc. were all suggested to someone in a similar situation.
Common collector circuits were where my eyes crosses and I decided to make this post. Think you could point me in the right direction or possibly make a suggestion for a particular component, knowing the situation?
-oh, and in my travels I read that the voltage of a battery falls as it is discharged. Is that true too? How would I compensate for that?
Thanks in advance - I just found this site a few days ago.. never have a lurked for such a short amount of time before I got interested enough to make an account! Well done, AAC.
