Hello,
//For people who remember me from previous question about Bar Led driver, with 10.5V relay disable circuit. I don't forget about this project. I don't forget about You guys who spend time to help me!. I just have spending some time to learn many things. I decide to use IC, called Atmega. I finished writing application (firmware), i tested it using Atmega8, but it's to big (it's overkill), and i'm waiting for shipping atmega tiny, in dip 8 package. When i will be done, i will answer in that thread and show working project on my breadboard. I appreciated Your help, and i promise when i will have something to show i will!.
Today's question:
I would like power my 12V fan, from USB.
Please don't tell me i should buy 5V, because i was unable to find perfect size. It's slim fan, quiet...
I't take only 0,06A with 12V.
Any of step-up converters are not possible, because of problem in getting IC for it.
I found this project:
http://www.eleccircuit.com/voltage-doubler-with-ic-555/
It's voltage doubler, if i understand corect it will get me about 10V from 5V usb.
Question is, is this charge pump, can provide 0,06A ?
It's very little 60mA, just like 3 LED.
If anyone was trying that device, please tell me the current at output.
Regards
