-Circuit overview.  An op amp and darlington transistor will be used as a constant current source.  A second op amp will amplify the current signal for input to the PIC.  A third op amp will amplify and condition the voltage signal for the PIC.  The op amps will be powered by a single 5 volt power supply. Input voltage will be between 12 and 25 volts so that many cell batteries can be charged.  To reverse the current for discharge 2, 2 pole relays will be used.  The relays could be replaced by a double pole double throw switch ( the user, not the software would have to be used to throw the switch ).

 Board design will be in Eagle, single sided for Toner Transfer.

		+	Anything you want to do is fine, it could include:
		+
		+	* Just building ( and testing ) the charger
		+	* Improving and/or extending the board, a more compact board, adding a PIC and power supply..... are possible ideas.
		+	* Writing alternative PC interfaces for the hardware, some might prefer .Net or....
		+	* Enhancing the Java program ( you need to let me finish what I am doing first )
		+	* Testing the Java -- some can be done using any device with a serial port, I have a simulator that substitutes for some of the hardware.
		+	* You can just lurk, that is participate in a stealth mode.
		+	* Add to the list anything that occurs to you, I will let you know if it works for me.
