I have an RSSI output from my receiver. I would like to wake up the rest of the circuit when the RSSI output voltage goes above 0.6V. This voltage is uaually 0.4V and can go upto 1.5V. The system is running on a 3V supply. So I want to convert the voltage as follows
dc voltage 1v to 5v
These have been discussed here before but my application is a bit different.
I want to generage 5V from 1V. However my source is a solarcell and th output is a few milliamps, usually between 1 and 5mA. I want to use this to top-up a rechargable battery, however due to...
circuit diagram of rc helicopter
I am trying to make my own transmitter that should work with 40MHZ OOK reciever for RC helicopter. I have found this circuit from net.
but i dont understand this well or how to conver it to 40mhz.
i am designing a micro controller circuit that is powered by usb. but some of the functionality need +5 to -5 volt range while usb provides only +5 volt, is there an easy way to convert the +5 to -5 volts as well?
